It’s definitely A
Ex: f(x)=8x+2
f(x)=8(-4)+2
f(x)=-32+2
f(x)=-30
First question is 1:2
Second question is 12
The first answer is C because the prompt says the total was lessthan 13. Also, the cost of the necklace is added to the cost, not subtracted.
5b+3.5<13
5b<9.5
b<1.9
Because it must be less than 1.9, the highest possible price is $1.89
Parallel means they have same gradient.
m=(y2-y1)/(x2-x1)
m=(5-(-4))/(3-(-2))
m=9/5
so the answer is B since the gradient also 9/5
