Answer: [tex](f-g)(x)=-x+10[/tex]

Step-by-step explanation:

Given the function f(x):

[tex]f(x)=3x-1+4[/tex]

And given the function g(x):

[tex]g(x)=4x-7[/tex]

You must subtract both functions is order to find [tex](f-g)(x)[/tex].

You need to remember the multiplication of signs:

[tex](+)(+)=+\\(-)(-)=+\\(+)(-)=-[/tex]

Then:

[tex](f-g)(x)=3x-1+4-(4x-7)[/tex]

Now, you must distribute the negative sign:

[tex](f-g)(x)=3x-1+4-4x+7[/tex]

And finally, add the like terms. Then you get that  [tex](f-g)(x)[/tex] is:

[tex](f-g)(x)=-x+10[/tex]

ANSWER

[tex]b \geqslant - 18[/tex]

EXPLANATION

The given inequality is:

[tex] - 18 \leqslant b[/tex]

We can rewrite this as:

[tex]b \geqslant - 18[/tex]

The above two inequalities have the same meaning.

Reading from right to left, the first inequality says, "b is greater than or equal to negative 18."

Reading from left to right, the second inequality says, "b is greater than or equal to negative 18."

Therefore the two inequalities have the same meaning.

Step-by-step Answer:

Many inequalities are possible, for example:

Keeping the less than or equal to sign, we could write

-18-b<=0

or, switching sides,

b>= -18   (just by switching sides)

b+18>=0  (by transposing -18 to the left)

Then again, we can multiply both sides by -1, but we need to change the direction of the inequality:

18>=-b

or equivalently, by transposing 18 to the other side

0>=-b-18

and similarly

b+18>=0  (we already had this above)

Answer:

3.6 hours

Step-by-step explanation:

Blake can do work in hours = 9

Blake can do a part of work in 1 hour = [tex]\frac{1}{9}[/tex]

Ned can paint the same room in six hours.

Ned can do a part of work in 1 hour = [tex]\frac{1}{6}[/tex]

They can do a part of work together in 1 hour =  [tex]\frac{1}{9}+\frac{1}{6}[/tex]

                                                                           =  [tex]\frac{5}{18}[/tex]  

Now they can do [tex]\frac{5}{18}[/tex]  part of work in hour = 1

So, they can do whole work in hours =  [tex]\frac{1}{\frac{5}{18}}[/tex]

                                                             =  [tex]3.6[/tex]

Hence it will take 3.6 hours to paint the room if they work together.

Answer:

The range is 19

Step-by-step explanation:

First, you have to order the numbers from least to greatest:

-9.5, -3.1, 3.1, 3.2, 4.7, 4.9, 5.4, 6.3, 9.5

Then, you have to find the difference between the largest number and and smallest number. You do this by subtracting them:

9.5 - (-9.5)= 19

So, the range is 19

ANSWER

1. No solution

2. 4 and 6

3. 81

EXPLANATION

1. The given quadratic equation is

[tex] {x}^{2} + 1 = 0[/tex]

This implies that:

[tex] {x}^{2} = - 1[/tex]

There is no real number whose square is negative one.

This quadratic equation has no solution.

2. The given quadratic equation is

[tex] {x}^{2} - 10x + 24 = 0[/tex]

We split the middle term with -6,-4 because their product is 24 and their sum is -10

[tex]{x}^{2} - 6x - 4x+ 24 = 0[/tex]

We factor by grouping

[tex]{x}(x - 6)- 4(x - 6)= 0[/tex]

[tex](x - 6)(x - 4)= 0[/tex]

We have x=4 and x=6.

3. The given quadratic equation is

[tex] {x}^{2} - 18x = 7[/tex]

We the square of half the coefficient of x to both sides of the equation.

[tex]( - \frac{18}{2} )^{2} = ( { - 9)}^{2} = 81[/tex]

The correct choice is C.

Answer:

The equation [tex]y=x^2+1[/tex] will be a parabola when it is graphed

Answer:

It's a parabola

Step-by-step explanation:

The equation seems to a parabolic function. The parabola is defined as:

[tex]y=Ax^2+b[/tex]

where b is a displacement, we can notice that in our case A=1 and b=1

so it is a parabola with a vertical displacement of one unit.

Answer:

2/5

Step-by-step explanation:

There are 10 marbles and 4 of them are purple. That would give you the fraction 4/10. 4/10 can be simplified to 2/5. So, you have a 2/5ths chance of choosing a purple marble.

The probability of selecting a purple marble from a bag containing 10 marbles, 4 of which are purple, is 2/5.

The question asks: "A bag contains 10 marbles. Four of the marbles are purple. What is the probability you will choose a purple marble from the bag?" To find the probability, you divide the number of favorable outcomes (choosing a purple marble) by the total number of outcomes (all the marbles in the bag). Here, there are 4 purple marbles and 10 marbles in total.

The probability is therefore 4/10, which can be simplified to 2/5. So, the probability of choosing a purple marble from the bag is 2/5.

I would say option A best proves it is a parallelogram.

Answer:

360

Step-by-step explanation:

f varies directly as g

f = kg  where k is the constant of variation

f varies inversely as h

f = kg/h

We know g = 198 when  h = –11 and f = –6.  Substituting in

-6 = k*198/(-11)

-6 =k*(-18)

Dividing each side by -18

-6/-18 = k*-18/-18

1/3 =k

Our equation is

f = 1/3 g/h

Letting  f = 12 and h = 10

12 = 1/3 g/10

Multiply each side by 10

12*10 =1/3 g/10*10

120 = 1/3 g

Multiply each side by 3

120*3 =1/3 g *3

360 =g

Answer:

The cost of one pack of paper was $0.90 and the cost of one box of pens was $2.00

Step-by-step explanation:

Let

x----> the cost of one pack of paper

y---> the cost of one box of pens

we know that

10x+12y=33 ----> equation A

15x+7y=27.50 ---> equation B

Solve the system of equations by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution is the point (0.9,2)

see the attached figure

Therefore

The cost of one pack of paper was $0.90

The cost of one box of pens was $2.00

Answer:

pens = $2

paper = .9

Step-by-step explanation:

p = price of a pack of paper

n =  price of a box of pens

10p + 12n = 33

15p + 7n = 27.50

Multiply the first equation by 3

3(10p + 12n )= 33*3

30p +36n = 99

Multiply the second equation by -2

-2(15p + 7n) = 27.50*-2

-30p -14n = -55

Add the 2 modified equations together

30p +36n = 99

-30p -14n = -55

--------------------

    22n = 44

Divide each side by 22

22n/22 = 44/22

n =2

Each box of pens is $2

Now we can find the price of the paper

10p + 12n = 33

10p +12(2) = 33

10p +24 =33

Subtract 24 from each side

10p+24-24=33-24

10p = 9

Divide by 10

10p/10 =9/10

p = .9

Answer:

5(1248 lb/horse + t lb) ≤ 8000 lb

Step-by-step explanation:

One way to do this is to find the average weight of the 5 horses:

It is:

6,240 lb

---------------- = 1248 lb/horse

  5 horses

and to this, for each horse, we must add t lbs tack.

Thus, 5(1248 lb/horse + t lb) ≤ 8000 lb

would be an appropriate inequality.

Answer:

10 pairs of earrings and 5 necklaces (the maximum profit will be $250)

Step-by-step explanation:

Let x be the number of earrings and y be the number of necklaces Lisa makes.

1.  Lisa only has enough materials to make 15 total jewelry items per week, then

[tex]x+y\le 15.[/tex]

2.  It takes half an hour to make a pair of earrings, so it takes her [tex]\dfrac{1}{2}x[/tex] hours to make x earrings. It takes her 1 hour to make a necklace, so it takes her y hours to make y necklaces. Lisa only has 10 hours a week to make jewelry, thus

[tex]\dfrac{x}{2}+y\le 10[/tex]

3. Lisa makes a profit of $15 on each pair of earrings and $20 on each necklace. In total her profit is

[tex]P=15x+20y.[/tex]

You have to find the maximum value of the function [tex]P=15x+20y[/tex] with respect to inequalities

[tex]x+y\le 15\\ \\\dfrac{x}{2}+y\le 10[/tex]

Draw the solution set on the coordinate plane (see attached diagram). The maximum value of the efunction P is at point (10,5) and is

2, -1. I think, possibly.

Answer:

3, -1

Step-by-step explanation:

Answer:

hypotenuse = 20

leg = x + 4

other leg = x

From the Pythagorean Theorem we know that

20^2 = (x + 4)^2 + x^2

400 = x^2 + 8x + 16 + x^2

2 x^2 + 8x -384 = 0

Solving the quadratic equation we get

x = 12 and x = -16

x = 12 and so the lengths of the 2 legs are:

12 and 16

Right Triangle Area = (leg1 * leg2) / 2

Right Triangle Area = (12 * 16) / 2

Area = 192 / 2

Area = 96 square centimeters

Step-by-step explanation:

To find the area of the triangle, we used the Pythagorean theorem to solve for the legs, obtaining lengths of 16 cm and 12 cm. The area is then calculated using the formula for the area of a right triangle (1/2 * base * height), resulting in an area of 96 cm².

We are given a right triangle with a hypotenuse of 20 cm and two legs where one leg (let's call it a) is 4 cm longer than the other leg (let's call it b). Using the Pythagorean theorem, we can express the relationship between the legs and the hypotenuse: a² + b² = 20². We know that a = b + 4, so if we substitute a into the equation, we get:

(b + 4)² + b² = 400

b² + 8b + 16 + b2 = 400

2b² + 8b - 384 = 0

Dividing everything by 2, we get:

b² + 4b - 192 = 0

Using the quadratic formula or factoring, we find that b = 12 (b can't be negative). Consequently, a = 16. The area of the triangle is given by 1/2 * base * height, which is:

Area = 1/2 * a * b

Area = 1/2 * 16 * 12

Area = 1/2 * 192

Area = 96 cm²

Answer:

C) 50,653

Step-by-step explanation:

y = 1000(3.7)^x

After 3 hours   x=3

y = 1000(3.7)^3

y = 1000(50.653)

y =50653

Answer: OPTION C

Step-by-step explanation:

You know that in the function [tex]y = 1000(3.7^x)[/tex] the variable "y" is the number of bacterias in a petri dish  and the variable "x" is the number of hours.

Then, to answer the question "How many bacteria will there be after 3 hours?", you need to substitute [tex]x=3[/tex] into the function.

Therefore, the number of baterias after 3 hours will be:

[tex]y = 1000(3.7^3)[/tex]

[tex]y = 1000(50.653)[/tex]

[tex]y = 50,653[/tex]

This matches with the option C.

Answer:

D

Step-by-step explanation:

Value of the function [tex]\lim_{x \to 4} \dfrac {g}{h}(x)[/tex] is zero.

Correct option is b.

Limits are defined as values ​​to which the function approximates the output for given input values. The limit is the unique real numbers. Given a real-valued function "f" and a real number "c", the limit is usually defined as [tex]\lim_{x \to c} f(x) = L[/tex]. We read that "the limit of f of x is equal to L as x approaches c". "lim" represents the limit, and the right arrow indicates that the function f(x) approaches the limit L as x approaches c.

Given functions,

[tex]\lim_{x \to 4} f(x) = 5 , \lim_{x \to 4} g(x) = 0, \lim_{x \to 4} h(x) = -2[/tex]

[tex]=\lim_{x \to 4} \dfrac {g}{h}(x)[/tex]

[tex]=\lim_{x \to 4} \dfrac {g(x)}{h(x)}[/tex]

[tex]=\dfrac{\lim_{x \to 4} g(x)} {\lim_{x \to 4} h(x)}[/tex]

= 0/-2

= 0

Hence, 0 is the value of function [tex]\lim_{x \to 4} \dfrac {g}{h}(x)[/tex] .

Answer

Midpoint (5, -2)

The midpoint of the graphed line segment is (5, -2)

The correct option is C) (5, -2).

The midpoint formula is expressed as;

Midpoint = ( ( x₁+x₂ )/2, ( y₁+y₂ )/2 )
