Answer: 63
Step-by-step explanation:
14.5x1.5=21.75
15x2.75=41.25
21.75+41.25=63
Step 1:
Subtract 3y from both sides
Step 2:
Divide both sides by -5
Answer:
x=3/5y + -22/5
Answers:
1) (s o t)(x)=4x^2-x-4
2) (t o s)(x)=4(x-7)^2-(x-7)+3
Solution:
1) (s o t)(x)=s(t(x))=s(4x^2-x+3)=(4x^2-x+3)-7=4x^2-x+3-7
(s o t)(x)=4x^2-x-4
2) (t o s)(x)=t(s(x))=t(x-7)=4(x-7)^2-(x-7)+3
(t o s)(x)=4(x-7)^2-(x-7)+3
