Dividing by 10 is simple; just move the decimal place one digit to the left. So, 8.0 would then be 0.8. However, it is imperative you show your working out:
8/10=0.8
Answer:
x = 13
y = 9
Step-by-step explanation:
Answer:
A. 7
B. -3
C. 8
D. 13
E. 5a+17
F.
+ 8a + 20
Step-by-step explanation:
A. f(1) = 5*1 +2, which equals 7
B. f(-1)= 5(-1)+2 which equals -3
C. g(-3)= (-3)^2+ 2(-3)+ 5 = 9- 6+ 5 = 8.
D. g(2)= (2)^2+ 2(2)+ 5= 4+ 4+ 5= 13.
E. f(a+3)= 5(a+3)+2 = 5a+ 15+ 2= 5a+ 17.
F. g(a+3)= (a+3)^2+ 2(a+3)+ 5=
+ 6a+ 9+ 2a+ 6+ 5=
+ 8a+ 20.
If these are all separate answers, then: y=3r-1
Substitute r for the value it's asking for.
R=-1
y=3(-1)-1
(Answer) y=-4
R=-8
y=3(-8)-1
y=-24-1
(Answer) y=-25
R=-4
y=3(-4)-1
