x = -4

y = -25

Step-by-step explanation:

Since one of the equations is already set with one variable as the subject ( y = 7x + 3) substitute that into the one below it:

9x - 2y = 14

9x - 2(7x + 3) = 14

9x - 14x - 6 = 14

-5x = 20

x = -4

Substitute this into one of the equations and solve for the other variable:

y = 7x + 3

y = 7(-4) + 3)

y = -28 + 3

y = -25

hope this helps!

(- 4, - 25 )

Step-by-step explanation:

Given the 2 equations

y = 7x + 3 → (1)

9x - 2y = 14 → (2)

Substitute y = 7x + 3 into (2)

9x - 2(7x + 3) = 14 ← distribute and simplify left side

9x - 14x - 6 = 14

- 5x - 6 = 14 ( add 6 to both sides )

- 5x = 20 ( divide both sides by - 5 )

x = - 4

Substitute x = - 4 into (1) for corresponding value of y

y = 7(- 4) + 3 = - 28 + 3 = - 25

solution is (- 4, - 25 )

i am currently in the exact same situation rn. algebra2/adv algebra is killing

step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
