Which of the following equations is equivalent to 2x+y = 7? a
y = -2x +7
Ob
y = 2x +7
y=2x-7
y=-2x-7
Od

a,y=‒2x+7

Step-by-step explanation:

2x+y=7

y=7‒2x or y=‒2x+7

i think it is easy to understand

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
