what is the value of y ​

Answer:

Option C

Step-by-step explanation:

We are given that

[tex]f(x)=-x[/tex]

The line passing through the points (0,0),(-6,6) and (6,-6).

[tex]g(x)=2x[/tex]

The line passing through the points (-3,-6),(0,0) and (3,6).

We have to find the graph of (g-f)(x).

[tex](g-f)(x)=g(x)-f(x)=2x-(-x)=2x+x[/tex]

[tex](g-f)(x)=3x[/tex]

Substitute x=0

[tex](g-f)(0)=3(0)=0[/tex]

[tex](g-f)(2)=3(2)=6[/tex]

[tex](g-f)(-2)=3(-2)=-6[/tex]

[tex](g-f)(-6)=3(-6)=-18[/tex]

Option C is true.

Step-by-step explanation:

Answer: Pedro= 1205. Ricky= 1488

Step-by-step explanation:

It is found that Ricky hits 1202 base and Pedro hits = 1485 base

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

Given that

Pedro + Ricky = 2693 hits

Let Ricky hits = x

So, the Pedro hits will be = x + 283

( x + 283 ) + x = 2693

2 x + 283 = 2693

2 x = 2693 - 283

2 x = 2404

x = 1202

So, the Ricky hits 1202 base

Thus Pedro hits (1202 + 283) = 1485 base

Answer: the answer is 5 feet per second

Step-by-step explanation:

Answer:

{(-34/7, -16/7)}

Step-by-step explanation:

Rearrange values, multiply to solve for x.

(5) 2y = 3x + 10

(-2) 5y = 4x + 8

Solve for x.

10y = 15x + 50 ↓

-10y = -8x -16

Combine and evaluate.

0 = 7x + 34

Subtract 34 from both sides.

7x = -34

Divide both sides by 7.

x = [tex]\frac{-34}{7}[/tex]

Plugin x value into either equation to solve for y.

2y = (3 × [tex]\frac{-34}{7}[/tex]) + 10

2y = [tex]\frac{-102}{7}[/tex] + 10

2y = [tex]\frac{-32}{7}[/tex]

y = [tex]\frac{-16}{7}[/tex]

Answer:

[tex]Area\ of\ a\ trinagle = \frac{5}{12}x^2[/tex] [tex]or\ 0.42x^2[/tex]

Step-by-step explanation:

Given:

Height of the triangle [tex]h = x[/tex]

Base of the triangle [tex]b=\frac{5}{6}x[/tex]

We need to find the area of the triangle.

Solution:

Using given Formula:

[tex]Area\ of\ a\ trinagle = \frac{1}{2}bh[/tex]

Where:

b = Base of the triangle.

h = Height of the triangle.

Substitute [tex]h = x[/tex] and [tex]b=\frac{5}{6}x[/tex] in equation in given formula.

[tex]Area\ of\ a\ trinagle = \frac{1}{2}(\frac{5}{6})x\times x[/tex]

[tex]Area\ of\ a\ trinagle = \frac{5}{12}x^2[/tex]

[tex]Area\ of\ a\ trinagle =0.42x^2[/tex]

Therefore, Area of the triangle is [tex]\frac{5}{12}x^2[/tex] or [tex]0.42x^2[/tex].

Diaz family spend $ 20 if they bought 3 adults tickets and 1 children's ticket

Solution:

Let "a" be the cost of each adult ticket

Let "c" be the cost of each student ticket

The Spencer family bought 3 adult tickets and 2 children's tickets for $23.50

Therefore, we frame a equation as:

[tex]3 \times a + 2 \times c = 23.50[/tex]

3a + 2c = 23.50 --------- eqn 1

The Yang family bought 2 adult tickets and 4 children's tickets for $25

Therefore, we frame a equation as:

[tex]2 \times a + 4 \times c = 25[/tex]

2a + 4c = 25 ----------- eqn 2

Let us solve eqn 1 and eqn 2

Multiply eqn 1 by 2

6a + 4c = 47 ---------- eqn 3

Subtract eqn 2 from eqn 3

6a + 4c = 47

2a + 4c = 25

( - ) --------------

4a = 47 - 25

4a = 22

Divide both sides of equation by 4

a = 5.5

Substitute a = 5.5 in eqn 1

3(5.5) + 2c = 23.50

16.5 + 2c = 23.50

2c = 23.50 - 16.5

2c = 7

Divide both sides of equation by 2

c = 3.5

Thus, cost of each adult ticket = $ 5.5

Cost of each student ticket = $ 3.5

How much would the Diaz family spend if they bought 3 adults tickets and 1 children's ticket?

Total cost = 3a + 1c

Total cost = 3(5.5) + 1(3.5) = 16.5 + 3.5

Total cost = 20

Thus Diaz family spend $ 20

Final answer:

The Diaz family would spend $20 for 3 adult tickets and 1 children's ticket at the zoo after solving the system of linear equations given by the Spencer and Yang families' purchases.

Explanation:

Let A be the price of an adult ticket and C be the price of a children's ticket. We are given:

3A + 2C = $23.50 (Spencer family)

2A + 4C = $25 (Yang family)

To solve this system, we can multiply the first equation by 2 and the second equation by 3:

6A + 4C = $47 (Spencer family doubled)

6A + 12C = $75 (Yang family tripled)

Subtracting the first equation from the second gives us:

8C = $28

Dividing both sides by 8 yields:

C = $3.50

Now that we know the price of a children's ticket, we can substitute this value back into one of the original equations to find the price of an adult ticket.

3A + 2(3.50) = $23.50

3A + $7 = $23.50

3A = $16.50

A = $5.50

With the price of both ticket types known, we can now calculate the cost for the Diaz family:

3A + 1C = 3($5.50) + 1($3.50)

3A + 1C = $16.50 + $3.50

3A + 1C = $20

Therefore, the Diaz family would spend $20 if they bought 3 adult tickets and 1 children's ticket.

Answer:

The aquarium needs 56 more gallons to be completely filled.

Step-by-step explanation:

To get the amount remaining you have to first divide 1120 by 100

1120/100=11.2

Then multiply it by 95

11.2*95=1064

You take the maximum amount (1120) and subtract the amount in the tank (1064) to get the amount left.

1120-1064= 56

With 56 gallons as your final answer.

Answer:

t = -8

Step-by-step explanation:

combine like terms, so -3t + 7t = 4t and 34 - 2 = 32

so 4t - 8 = 32 + 9t

then subtract 4t from both sides and subtract 32 from both sides. You will get: -40 = 5t.

Then divide both sides by 5 so you will get -8 = t

Answer:

The number of faculty member is 45.

Step-by-step explanation:

Ratio of faculty members to students = 1 : 15

Number of students = 675

Total = Number students + faculty members

Let the total be t

Let the faculty member be f

Representing the ratio, we have:

[tex]\frac{15}{16} * t = 675\\\frac{15t}{16} = 675\\15t = 16 * 675\\15t = 10800\\\frac{15t}{15} =\frac{10800}{15} \\t = 720[/tex]

Therefore, the total number of both the students and faculty member is 720. To get the number of faculty member:

Total = Number students + faculty members

[tex]720 = 675 + f\\f = 720 - 675\\f = 45[/tex]

The number of faculty member is 45.

Final answer:

The scientist used 9/40 of a full bottle of solution.

Explanation:

To find out how much of a full bottle of solution the scientist used, we first need to calculate the amount that is left in the bottle. The bottle is currently 5/8 full, and the scientist used 2/5 of the solution. To calculate the amount left, we subtract the amount used from the initial amount:

Amount Left = Initial Amount - Amount Used

To subtract fractions, we need a common denominator. The common denominator for 8 and 5 is 40:

Amount Left = 5/8 - 2/5

To subtract the fractions, we need to have the same denominator, which is 40:

Amount Left = (5/8) * (5/5) - (2/5) * (8/8)

Amount Left = 25/40 - 16/40

Amount Left = 9/40

Therefore, the scientist used 9/40 of a full bottle of solution.

Answer:

Each apples cost about $0.14

The linear equation representing the value of the car as it depreciates over time is y = -3,000x + 25,635, where y is the value of the car and x is the age of the car in years.

To write a linear equation that describes the depreciation of the SUV over time, we define two variables: y represents the total value of the car at any time x, where x represents the age of the car in years.

The car is purchased for $25,635 and depreciates at a rate of $3,000 per year, which means that the value of the car decreases by a constant amount each year. We can write this situation as a linear function:

Linear Depreciation Equation:

y = -3,000x + 25,635

Here, the y-intercept is $25,635 (the value of the car at the time of purchase when x is zero), and the slope is -$3,000 (the rate at which the value of the car decreases per year).

Answer:

1 necklace is $19!

Step-by-step explanation:

4•$8=$32

$70-$32=$38

$38/2=$19

Answer:

lets consider an example like

20 divided by 2/4 so we can rewrite as

2/4*  x      =20

so , 2*   x     =20*4

2*     x      =80

x=80/2

x=40

similarly,we can write the fraction as (20*4/2)-we can see that reciprocal of the fraction 2/4 is 4/2

x=20*4/2=80/2=40

so, we can say that dividing by a fraction results in the same answer as multiplying by its reciprocal.

At 4 miles per hour?

Time = 24/4 = 6 hours

At 6 miles per hour?

Time = 24/6 = 4 hours

b. Write an equation that Han can use to find t, the time it will take to ride 24 miles, if his rate in miles  per hour is represented by r.
