Answer:
A) 5x-7y=58
B) y=-x+2 we rearrange B) into
B) x + y = 2 then we multiply B) by -5
B) -5x -5y = -10 adding this to A)
A) 5x -7y = 58 we get
-12y = 48
y = -4
B) x + y = 2
x = 2 +4
x = 6
Step-by-step explanation:
From question,
lacy learned 34 recipes in 17 weeks,
so in 1 week she learns = 34/17 =2 recipes,
hence she learns 40 recipes in
= 40*2
=80 recipes.
Y = mx + b
m = -2, b = 4
<span>y = -2x + 4</span>
