Answer:
Step-by-step explanation:
A liter of milk cost $.75
A loaf of bread cost $1.75
If a solution(s) exists y=y so we can say:
x^2-3x=-2x+2 add 2x to both sides
x^2-x=2 subtract 2 from both sides
x^2-x-2=0 factor
(x-2)(x+1)=0
So x=-1 and 2, using y=-2x+2 we find:
y(-1)=4 and y(2)=-2
So the two solutions occur at the points:
(-1,4) and (2,-2)
Answer:
12.5
Step-by-step explanation:
f of x just means y, so you're just finding y when x = 1/2
