Answer:
<u>18</u>
Step-by-step explanation:
<em>replace a with -2</em>
-4(-2) + 10
<em>multiply the -4 and the -2, the negatives cancel out and leave you with 8</em>
8 +10
<em>just add</em>
18
f-¹(x)=
Answer:
Solution given:
f(x)=
Let f(x)=y
y=
Interchanging role of x and y
x=
doing crisscrossed multiplication
x(y+7)=-2y+2
now solve it:
xy+7x=-2y+2
keep like terms in one side
xy+2y=2-7x
take common
y(x+2)=2-7x
make a value of y
y=
So,
f-¹(x)=
Answer:
Step-by-step explanation:
This is more easily understood if you take out a common factor of -1
-1(x^2 + 15x + 56)
7*8 = 56
7 + 8 = 56
-1 (x +8)(x+7)
So.

Let's get started with formulas.
.
I KNOW you hate formulas!! So do I, but we have to use them. No "buts".
.
So, how many minutes are in 2 weeks?
.
Search it up. For your convenience, it is 20,160 minutes.
.
Well, I think you have your answer, since each quiz is 5 minutes, 5 times 50 (5 x 50) is 2,500 minutes.
.
Yes, you can do 50 quizzes and MUCH MUCH more in 2 weeks.

Hope I helped!!
