Hello from MrBillDoesMath!
Answer:
Choice D.
Discussion:
Substitute x = 9 in the choices
A. when x = 9, x^2 - 6x + 9 = 36
B. when x = 9, x^2 + 16x + 63 = 288
C. when x = 9, x^2 + 14x + 45 = 252
D. when x = 9, x^2 -12x + 27 = 0
Thank you,
MrB
Answer:
15
Step-by-step explanation:
35
12 + 25y = 795
12(y + 20) + 25y = 795
12y + 240 + 25y = 795
37y = 795 - 240
37y= 555
y=15
Substitute y= 15 into
x=y + 20
x= 15 + 20
x= 35
T-shirt = 35
Sweatshirt = 15
They brought 35 t shirts
Answer:
Discontinuity of function occurs when x = 4 or x = -4
zero of function is when x=0
Step-by-step explanation:
We are given:

Discontinuity of the function occur when the denominator is equal to zero.
So, we need to find the values of x that makes the denominator zero.
The denominator is x^2 - 16
x^2 - 16 =0
x^2 = 16
x = ± 4
So, if the value of x = 4 or value of x=-4 then the function will be discontinuous.
Zero of the function i.e f(x)=0
So, Putting the function equal to zero and finding the value of x

So, zero of function is when x=0
Answer:
the slope should be y= -3/2x+2
