Answer:

-8

Step-by-step explanation:

Given that x and y are two variables.  they are related by the function

y =8-2x

Since x and y are related, given one value we can find the other using this equation.

In our question, given that x =8

Substitute x value in the equation

y = 8-2x

y =8-2(8) = -8

Hence answer is -8:


Verify:  We verify by putting -8 for y and check whether x =8

-8=8-2x

Or 2x = 16

x =8

Write an equation for a line that has slope of 4 and y- intercept of 7
grigory [225]

Answer:

y = 4x + 7

Step-by-step explanation:

the equation for a line is y = mx+b

the y intercept is (0,7)

so in the equation x= 0 and y= 7 and the slope is m, thus m= 4

7= (4)(0)+b

now solve for b

7 = 0 +b

7= b

so the equation of the line would be without the x and y points

y = 4x + 7

Ivahew [28]

The number of days d, he must use the gym to make the membership worthwhile is at least 21 days

Equation

Non members:

Cost of swimming per day = $5

Cost of exercise per day = $9

Swimming fee = $0

The number of days d, he must use the gym to make the membership worthwhile = $300 ÷ 14

= 21.42857142857142

Approximately,

21 days
