Answer:
-22
Step-by-step explanation:
f(x) = -x2 + 4x - 9
g(x) = x - 8,
g(f(-1))
First find f(-1)
f(-1) = - (-1)^2 + 4(-1) - 9 = -1 -4-9 = -14
The find g(-14)
g(-14) = -14-8 = -22
You can solve by subtracting: 500-330
but I like to use mental math and think this way:
she has 330
70 more will give her 400
and 100 more will give her 500
100 + 70 is 170.
Answer:
I think it's the last one D
Step-by-step explanation:
I'm not 100% sure, but I think the x can't repeat and 4 is the only number of x that hasn't been plotted yet. Tell me if it was right?
Answer:x=8
Step-by-step explanation:
You have to subtract 12 to 4
So x=8
Cos(sin⁻¹(³/₅))
cos(36.87)
