1) (f + g)(2) = 7 + 3 = 10 The answer is C
2) (f - g)(4) = 11 - 15 = -4 The answer is A
3) f(1) = 2(1) + 3 = 5 g(1) = 1² - 1 = 0 The answer is D
4) (f xg ) (1) = 7/3 The answer is B
650* 2/100* 6
= 78

Do you need it explained or just the answer
Hmmmm
the 1 in 435.15 is worth 0.1 or 1/10
1/10 of 1/10 is 1/10 times 1/10 or 1/100 or 0.1/10 or 0.01/1 or 0.01
so we want one with the 1 that is 2 spaces to the right of the decimal
that is choice H
remember, when you divide by 10, move the decimal to the left 1 space
H is the answer
3.5x - 1 = -1/2(-7x + 2)
3.5x - 1 = 7/2x - 1 By virtue of the distributive property
7/2 = 3.5, so there is no solution. The statement is true for any value of x.
Essentially it boils down to -1 = -1, which is always true.
