Start from the inside and work your way out
For f(g(0)), g(0)= 9-(0^2) = 9, f(9)= 5(9)+9 = 54
So f(g(0)) = 54
For g(f(0)), f(0)= 5(0)+9 = 9, g(9)= 9-(9^2) = -72
So g(f(0)) = -72
Write the equation: x + 42 + 30 = 131
Combine like terms: x + 72 = 131
Subtract 72 from both sides: x = 59
Answer:
Answer is A. 3 + 1.5 b < 15.
Step-by-step explanation:
Look at the problem carefully. Variable (b) represents <u>books</u>, and it states that the books weigh 1.5 lbs each. So you add her lunch (1 lb) and her shoes (2 lbs) to get 3 lbs. Once you add it together, it's less than (<) 15 lbs.
I tried to make this as understandable as possible, hope it helps.
Answer:
14
Step-by-step explanation:
In point-slope form, the equation with slope -7 through point (3, 0) can be written ...
y = -7(x -3) +0
y = -7x +21 . . . . . eliminate parentheses
Here, we can see m=-7 and b=21, so ...
m+b = -7+21 = 14
