30 points for right answer! solve the system of equations using linear combination and show your work. g + h = 9 8g + 7.5h = 71

Given the system of equation:

g +h = 9                        ......[1]

8g + 7.5h = 71               ......[2]

We can write equation [1] as;

g = 9-h        ......[3]

Now, substitute equation [3] in [2] we get;

Using distributive property i,e .

72 - 8h +7.5h = 71

Combine like terms:

72 - 0.5 h = 71

Subtract 72 to both sides of an equation:

72 - 0.5 h -72 = 71-72

Simplify:

- 0.5 h = -1

Divide both sides by -0.5 we get;

Simplify:

h = 2

Substitute the value of h =2 in equation [3] to solve for g;

g = 9 - 2 = 7

g = 7

Therefore, the solution for the given equation is :

g = 7 and h = 2

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
