Frank is saving money in an account. At the beginning of the year, he had $50 in his savings account already, which represents his y-intercept, and he put another $10 per week into the
savings, which is the average rate of change. Which equation could model this situation?

50 over 10 is equal to the rate of change. So, 50/10=roc.

Step-by-step explanation: Rate of change is change in y over change in x: y/x

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
