Two equations are given below
a - 3b=4
a= b - 2

what is the solution to the set of equations in the form (a, b)?

(-5,-3)

Step-by-step explanation:

In this case to find the solution you could use substitution. This way you can solve without changing the equation over again.

(b - 2) - 3b = 4

b - 2 - 3b = 4

-2b - 2 = 4

-2b = 6

b =  -3

Plug back in to find value a

a = (-3) - 2

a = -5

Check your answer before submitting

(-5) - 3(-3) = 4

-5 + 9 = 4

4 = 4

Hope this helps

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.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
