How many solutions does the system have?
y=4x+4
y=x^2+4

2 solutions  (0, 4) and (4, 20)

Step-by-step explanation:

you can solve by substitution

y=4x+4 and y=x²+4 so you can say that

4x+4=x²+4

subtract (4x+4) from both sides to get an equation that equals 0

0=x²-4x    (the 4 cancels itself out, 4-4)

simplify, solve for x

0=x(x-4)

set each part =0 and solve

x=0  x-4=0

so x=0 and x=4

plug each solution back into one of the equations

y=4(0)+4

y=4

(0, 4) is one solution

y=4(4)+4

y=20

(4, 20) is another solution

so you have 2 solutions, (0, 4) and (4, 20)

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
