Step-by-step explanation:

4.5 + 1.5k = 18 - 3k

Bring -3k to the other side by adding 3k to both sides

4.5 + (1.5k + 3k) = 18 + (-3k + 3k)

4.5 + 4.5k = 18 + 0

4.5 + 4.5k = 18

Bring 4.5 to the other side by subtracting it to both sides

(4.5 - 4.5) + 4.5k = 18 - 4.5

0 + 4.5k = 13.5

4.5k = 13.5

Isolate k by dividing 4.5 to both sides

4.5k / 4.5 = 13.5 / 4.5

k = 3

Answer:

Distance divided by time

I would say that’s correct

OOF yes it's correct...

you just cancel out the x variable first since 4x-4x is 0 then you bring down your y variable and solve for x then you plug x into either equation then solve for x.

QUESTION 1

We have [tex]f(x)=\frac{2x-1}{x+2}[/tex]

Let [tex]y=\frac{2x-1}{x+2}[/tex]

Interchange x and y.

[tex]x=\frac{2y-1}{y+2}[/tex]

Solve for y.

First, cross multiply;

[tex]x(y+2)=2y-1[/tex]

Expand now:

[tex]xy+2x=2y-1[/tex]

Group the y-terms on the LHS

[tex]xy-2y=-2x-1[/tex]

Factor y on the left hand side;

[tex](x-2)y=-2x-1[/tex]

Divide both sides by (x-2).

[tex]y=\frac{-2x-1}{x-2}[/tex]

[tex]f^{-1}(x)=\frac{-2x-1}{x-2}[/tex]

[tex]\boxed{f(x)=\frac{2x-1}{x+2}\to f^{-1}(x)=\frac{-2x-1}{x-2}}[/tex]

QUESTION 2

Given: [tex]f(x)=\frac{x-1}{2x+1}[/tex]

Let  [tex]y=\frac{x-1}{2x+1}[/tex]

Interchange x and y.

[tex]x=\frac{y-1}{2y+1}[/tex]

Solve for y

[tex]x(2y+1)=y-1[/tex]

[tex]2xy+x=y-1[/tex]

[tex]2xy-y=-x-1[/tex]

[tex](2x-1)y=-x-1[/tex]

[tex]y=\frac{-x-1}{2x-1}[/tex]

[tex]f^{-1}(x)=\frac{-x-1}{2x-1}[/tex]

[tex]f^{-1}(x)=\frac{-x-1}{2x-1}[/tex]

[tex]\boxed{f(x)=\frac{x-1}{2x+1}\to f^{-1}(x)=\frac{-x-1}{2x-1}}[/tex]

QUESTION 3

Given : [tex]f(x)=\frac{2x+1}{2x-1}[/tex]

We let  [tex]y=\frac{2x+1}{2x-1}[/tex]

Interchange x and y.

[tex]x=\frac{2y+1}{2y-1}[/tex]

Solve for y;

[tex]x(2y-1)=2y+1[/tex]

[tex]2xy-x=2y+1[/tex]

[tex]2xy-2y=x+1[/tex]

[tex](2x-2)y=x+1[/tex]

[tex]y=\frac{x+1}{2x-2}[/tex]

[tex]f^{-1}(x)=\frac{x+1}{2(x-1)}[/tex]

[tex]\boxed{f(x)=\frac{2x+1}{2x-1}\to f^{-1}(x)=\frac{x+1}{2(x-1)}}[/tex]

Step-by-step explanation:

Answer: Second Option

C(8,8)=1

Step-by-step explanation:

We must calculate a combination

The combination [tex]C (n, r) =\frac{n!}{r!(n-r)!}[/tex]

Where n is the number of elements that you can combine and you choose "r" from them.

So

C (8, 8) is the combination of 8 in 8.

Therefore

[tex]n = 8\\r=8[/tex]

[tex]C(8,8)= \frac{8!}{8!(8-8)!}\\\\C(8,8)=\frac{8!}{8!(0)!}\\\\C(8,8)=\frac{1}{1*1}\\\\C(8,8)=1[/tex]

The answer is the second option

The value of  [tex]\( C(8, 8) \)[/tex]  is 1 because choosing all 8 items from 8 yields only 1 combination.

The expression [tex]\( C(8, 8) \)[/tex] represents choosing 8 items from a set of 8 items without regard to order, which is also known as a combination. Here's how we can evaluate it step by step:

Step 1: Recall the formula for combinations.

The formula for combinations is [tex]\( C(n, k) = \frac{n!}{k!(n - k)!} \),[/tex] where [tex]\( n \)[/tex] is the total number of items and [tex]\( k \)[/tex] is the number of items to choose.

Step 2: Substitute the values into the combination formula.

In this case, [tex]\( n = 8 \) and \( k = 8 \),[/tex] so the expression becomes:

[tex]\[ C(8, 8) = \frac{8!}{8!(8 - 8)!} \][/tex]

Step 3:

Simplify the expression.

[tex]\[ C(8, 8) = \frac{8!}{8!0!} \][/tex]

Step 4:

Recall that [tex]\( n! = n \times (n - 1) \times (n - 2) \times \ldots \times 1 \)[/tex] and [tex]\( 0! = 1 \).[/tex]

[tex]\[ C(8, 8) = \frac{8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1}{8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 \times 1} \][/tex]

Step 5:

Cancel out the common terms.

[tex]\[ C(8, 8) = \frac{8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1}{8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1} \][/tex]

[tex]\[ C(8, 8) = 1 \][/tex]

So, [tex]\( C(8, 8) = 1 \).[/tex]

17) f(x) - g(x) = x + 9

Step-by-step explanation:

15)

f(x) = 3x + 5

g(x)= - 4x + 3

Find f(x) + g(x)

f(x) + g(x)  = 3x + 5  + ( - 4x + 3 )

Answer:

32

Step-by-step explanation:

Number of times a coin is tossed up = 5

Number of possible outcomes in a toss of a coin = 2 ( Head or a Tail)

The sample space can be calculated by calculating total number of possible outcomes in 5 tosses of the coin.

Number of outcomes in 1 toss of a coin = 2

Number of outcomes in 2 tosses of a coin = 2 × 2

Number of outcomes in 3 tosses of a coin = 2 × 2 × 2

Number of outcomes in 4 tosses of a coin = 2 × 2 × 2 × 2

Number of outcomes in 5 tosses of a coin = 2 × 2 × 2 × 2 × 2

⇒ Total number of outcomes = 32

Therefore, Size of the sample space = 32

Answer:

A.

⇒The slope of the function f(x) is greater than the slope of the function g(x).

This is so because using the slope intercept form equation, the slope of f(x) is 6 while that of g(x) is 5

B.

⇒The function f(x) has a greater y-intercept than the function g(x)

⇒The y intercept for the function f(x) is -1 where as that of the function g(x) is -4

Step-by-step explanation:

This question is on the standard equation of a linear function using the slope-intercept form

y=m x+c----------where m is the gradient/slope of the line and c is the y-intercept.

Given the values in function f(x) we can identify the points in the line as;

(-1,-7), (0,-1) , (1,5)............plot the points to obtain the graph as indicated in the attachment.

Find the gradient  of the graph ;

m₁=Δy/Δx

m₁= 5--1/1-0 =6/1 =6

Equation of line will be;

y-5/x-1 = 6

y-5=6(x-1)

y-5=6x-6

y=6x-1.........................m₁=6 and c₁= -1

Given that;

g(x)=5x-4.........................m₂=5   c₂= -4

⇒The slope of slope of the function f(x) is greater than the slope of the function g(x).

This is so because using the slope intercept form equation, the slope of f(x) is 6 while that of g(x) is 5

B.

⇒The function f(x) has a greater y-intercept than the function g(x)

⇒The y intercept for the function f(x) is -1 where as that of the function g(x) is -4

In the attached graph;

Red line graph, y=5x-4

Blue line graph, y=6x-1

Answer:

g(x) =   y=5x-4

f(x) =.    y= 6x-1

I know the slope of f(x) is greater than the slope of g(x) since the slope of f(x)=6 and g(x)=5 and 6>5.

I also know that the y-intercept of f(x) is greater because f(x)=-1 and g(x)=-4 and -1>-4.  

Step-by-step explanation:

First, I will put both functions into slope-intercept form.

Next, I will use  by picking two points on the table.  and

this equals  or 6.

So, I know the slope is 6.

To find the y-intercept I have to do, -7=6(-1)+b

So, the y-intercept is -1.

From this, I know the slope of f(x) is greater than the slope of g(x) since the slope of f(x)=6 and g(x)=5 and 6>5.

I also know that the y-intercept of f(x) is greater because f(x)=-1 and g(x)=-4 and -1>-4.

Answer:

[tex]\$16,021[/tex]  

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to  

[tex]V=P(1-k)^{x}[/tex]  

where  

V is the depreciated value  

P is the original value  

k is the rate of depreciation  in decimal  

x  is Number of Time Periods  

in this problem we have  

[tex]P=\$20,000\\k=0.105\\x=2\ years[/tex]

[tex]V=\$20,000(1-0.105)^{2}=\$16,020.50[/tex]  

round to the nearest dollar

[tex]\$16,020.50=\$16,021[/tex]  

the value of the car after 2 years will be approximately $16,212.

To find the value of the car after 2 years with continuous depreciation, we will use the formula for continuous exponential decay:

[tex]V(t) = V_0 \times e^{-kt}[/tex]

Where V(t) is the value after time t V_0 is the initial value, k is the decay constant and t is time

Plugging in the values:

[tex]V(2) = 20000 \times e^{-0.105 \times 2}[/tex]

Simplifying the exponent:

[tex]V(2) = 20000 \times e^{-0.21}[/tex]

[tex]V(2) = 20000 \times 0.8106 \approx 16212[/tex]

Thus, the value of the car after 2 years will be approximately $16,212.

Answer:

[tex]g^2+ 3g -10=(x-2)(x+5)[/tex]

Step-by-step explanation:

The trinomial is the following

[tex]g^2+ 3g -10[/tex]

Look for two numbers b and d that when multiplying them get as a result -10 and when you add up these numbers you get 3 as a result.

This is.

[tex]b * d = -10\\\\b + d = 3[/tex]

Then you can write the trinomial as the product of two factors:

[tex](x+b)(x+d)[/tex]

You can check that the numbers that meet this condition are:

[tex]b = -2\\d = 5[/tex]

Then the trinomial is written as

[tex]g^2+ 3g -10=(x-2)(x+5)[/tex]

Add the total number of rolls that were greater than 3.

This would be the number 4, 5 and 6.

8 + 11 + 10 = 29 rolls higher than 3.

Now divide the number of rolls higher than 3 by the total number of rolls which is given as 50:

29 / 50 = 0.58

Multiply by 100 to get the percent:

0.58 x 100 = 58% of the rolls were higher than 3.

Answer: 56.25

Step-by-step explanation:

You just need to use common sense.

Answer:

Answer is B - 290.

Step-by-step explanation:

The idea here is that we're assuming the frequency each colour is drawn is a reflection of the proportion of marbles in the bag that are that colour. The more of a particular colour you have, the more likely you are to draw it, and vice versa.

Therefore we can assume the proportion of blue, gree, and red marbles is 13%, 29%, and 58% respectively based on the first 100 draws.

These percents should stay relatively similar as more draws are done, approaching the true proportions of each colour better the higher the number of draws. That means 29%, or 290, of the 1000 draws will be green.

Answer: 290

Step-by-step explanation:

The boat traveled a distance of 80 km during the whole trip.

This question involves determining the distance a boat traveled based on its travel times with and against a current. Let's denote the speed of the boat in still water as b km/h.

Step-by-step solution:

Downstream, distance d = speed × time = (b + 6) × 4

Upstream, distance d = speed × time = (b - 6) × 10

Since the distances are equal:

(b + 6) × 4 = (b - 6) × 10

Expanding and simplifying:

4b + 24 = 10b - 60

84 = 6b

b = 14 km/h

Now, using the downstream speed to find the distance:

Distance, d = (b + 6) × 4 = (14 + 6) × 4 = 20 × 4 = 80 km.

Thus, the boat traveled a distance of 80 km.

The boat traveled 80 kilometers.

To determine how far the boat traveled, let's denote the speed of the boat in still water as B km/h. The current speed is given as 6 km/h.

Using the formula speed = distance/time, we get:

We now have two equations:

Setting the right-hand sides of these equations equal to each other:

4(B + 6) = 10(B - 6)

Simplifying this equation:

4B + 24 = 10B - 60

Bringing like terms together:

84 = 6B

Solving for B:

B = 14

Substituting B back into either distance equation, we use D = 4(B + 6):

D = 4(14 + 6) = 4(20) = 80

Therefore, the boat traveled 80 kilometers.

Answer:

FICA Tax =$8170.2

Step-by-step explanation:

Given

Total income=$165000

Taxable income=$106800

FICA tax includes Social security tax and medicare tax.  

Medicare tax is 1.45% of the taxable wage and social security tax is6.2% of the taxable wage.  

1.45% of medicare is paid by the employer and similarly 6.2% social security tax is paid by the employer.

0.9% of medical surtax is deducted if the employee earns more than $200000

So,

Medicare  Tax=Taxable income*1.45/100

=106800*0.0145

=$1548.6  

Social Security Tax=Taxable Income*6.2/100

=106800*0.062

=$6621.6

As the income of the employee is less than $200000, so there will be no medical surtax.  

Total FICA tax=$1548.6+$6621.6

=$8170.2

Answer:

315 hamburgers

Step-by-step explanation:

Because 3 times the amount of hamburgers were sold than the cheeseburgers, it is fair to say that 420 burgers is 4 times the amount of cheeseburgers sold.

That means that 420/4 = 105 cheeseburgers were sold.

That means that 105 * 3 = 315 hamburgers were sold.

The total number of hamburgers sold on Friday is 105

Number of Hamburgers sold = h

Number of Cheeseburgers sold = c

h + c = 420

c = 3*h

substitute the value of c in  ( h + c = 420 )

h + 3h = 420

4h = 420

h = [tex]\frac{420}{4}[/tex]

h = 105

The number of hamburgers sold is 105

Answer:

The solution of the equation are 3 , -11

Step-by-step explanation:

* Lets revise how to make the completing square

- The form of the completing square is a(x - h)² + k, where a , h , k

 are constant

- The general form of the quadratic is ax² + bx + c, where a , b , c

 are constant

- To change the general form to the completing square form equate

  them and find the constant a , h , k

* Now lets solve the problem

∵ x² + 8x = 33 ⇒ subtract 33 from both sides

∴ x² + 8x - 33 = 0

- lets change the general form to the completing square

∴ x² + 8x - 33 = a(x - h)² + k ⇒ solve the bracket of power 2

∴ x² + 8x - 33 = a(x² - 2hx + h²) + k ⇒ multiply the bracket by a

∴ x² + 8x - 33 = ax² - 2ahx + ah² + k ⇒ compare the two sides

∵ x² = ax² ⇒ ÷ x²

∴ a = 1  

∴ -2ah = 8 ⇒ substitute the value of a

∴ -2(1)h = 8 ⇒ -2h = 8 ⇒ ÷ (-2)

∴ h = -4

∵ ah² + k = -33 ⇒ substitute the value of a and h

∴ (1)(-4)² + k = -33

∴ 16 + k = -33 ⇒ subtract 16 from both sides

∴ k = -49

∴ x² + 8x - 33 = (x + 4)² - 49

* Now lets solve the completing square

∵ (x + 4)² - 49 = 0 ⇒ add 49 to both sides

∴ (x + 4)² = 49 ⇒ take square root for both sides

∴ (x + 4) = ± 7

∵ x + 4 = 7 ⇒ subtract 4 from both sides

∴ x = 3

∵ x + 4 = -7 ⇒ subtract 4 from both sides

∴ x = -11

* The solution of the equation are 3 , -11
