Rewrite the following equation in standard form. y = 9x+ 9/8

72x-8y=-9

Step-by-step explanation:

-72x+8y=9

Step-by-step explanation:

Given equation is

y=9x+9/8

Ax+By= C is the standard form of equation where x and y are variables and A,B and C are constants.

we have to change given equation into standard form.

y=9x+9/8

Adding -9x to both sides of above equation,we get

y+(-9x)=9x+9/8+(-9x)

y-9x=9x-9x +9/8

y-9x=0+9/8

y-9x=9/8

Multiplying by 8 to each term of above equation,we get

8.y-8.9x=8.9/8

8y-72x=9

-72x+8y=9

which is the standard form of given equation where A=-72,B=8 and C=9.

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.
