Answer:

The x-intercept is -7/5.

Step-by-step explanation:

Firstly, you must know what is intercept. Intercept is the line where it touches the axis. When a line touches the one axis, the other axis must be zero. So in this question, it given to us to find the x-intercept which means that y coordinate is zero. We have to let y equals to zero and solve for the value of x :

Let y = 0,

5x - y = -7

5x - 0 = -7

5x = -7

x = -7/5(improper fraction) or -1 2/5(mixed no.)

The equation 10x + 5y = 150

Verdich [7]

Answer:

x = 14.5 y = 1

Step-by-step explanation:

get the x alone by subtracting 5y from both sides

10x + 5y = 150

- 5y -5y

10x = -5y + 150

divide both sides by 10

10x = -5y + 150

10 10

x = -0.5y + 15

Now that we've solved for x, we can plug it into the original equation

10 (-0.5y + 15) + 5y = 150

now we solve for y the same way we did x

first distribute 10 into (-0.5y + 15)

-5 + 150 +5y = 150

now we get the y alone

-5 + 150 + 5y = 150

+5 -150 -150 +5

5y = 5

now divide by 5

5y = 5

5 5

y = 1

now that we have both x and y, we plug y into our solution for x

x = -0.5y + 15

x = -0.5(1) + 15

x= -0.5 + 15

x = 14.5

Verizon [17]

Answer: 50 cases per minute

Step-by-step explanation:

1. Select one of the points on the graph. Let's use (2, 100) in this case.

2. Divide the number of cases (y) by the amount of minutes (x) This means the equation would be 100 ÷ 2.

3. Since 100 cases ÷ 2 minutes = 50 cases per minute, that means that is unit rate, which can be expressed by y = 50x or f(x) = 50x.
