Answer:
D.
Step-by-step explanation:

Use the substitution method
Answers :
g(x)= -3x+1
a. g(10)= -3(10)+1
Mutiply first = -30
-30+1= -29
<em>g(10)= -29</em>
b. g(-2)= -3(-2)+1
Negative sign and negative sign = positive sign
-3(-2)= 6
6+1= 7
<em>g(-2)= 7</em>
a.
f(x)=x^2+7
f(3)= 3^ 2+7
3*3 because of the exponent. 3*3= 9
9+7= 16
<em>f(3)= 16</em>
d.
f(a)= a^2+7
a*a= a^2
a^2+7
<em>f(a)= a^2+7</em>
We know: length of a rectangle is 7m less than three times the width.
So let's set the length to l, width to w.
And we can get that l = 3w-7.
We also know that the area of the rectangle is 66 m^2.
Thus, l*w= 66.
So we have:
function 1: l=3w-7
function 2: l*w=66
plug function 1 to 2.
(3w-7)*w=66
3w^2-7w-66=0
w=6 and -11/3.
And the width of a rectangle can not be negative.
So: w=6.
Plug w=6 back to function 1 or 2, either way is correct and can give you the length. In this case, I will plug it back to function 1.
l=3*6-7=11.
So: the width of the rectangle is 6, and the length of the rectangle is 11.
Answer:
3x^2y^2
Step-by-step explanation:
I think:
3*2*x*x*x*y*y*y*y
3*3*x*x*y*y
3*6*x*x*x*y*y
They all have 3x^2y^2 in common.
Answer:
D)$732.84
Step-by-step explanation:
A=p(1+r/n)^nt
P=principal=$600
r=5%=0.05
t=4 years
n=12 months
A=p(1+r/n)^nt
=600(1+0.05/12)^12*4
=600(1+0.0041666666666 )^48
=600(1.0041666666666 )^48
=600( 1.2208953550215 )
=732.53
A=$732.53
Option D)$732.84 is the answer
