Y=5x+3 the domain is 3 but the answer is B.8
Answer:
The area of the shaded region is
Step-by-step explanation:
we know that
The area of complete circle subtends a central angle of 2π radians
so
A central angle of π radians subtends an area of semicircle
The area of semicircle is given by the formula
we have
substitute
therefore
The area of the shaded region is
Answer:
equaul
Step-by-step explanation:
Answer:
b=-11
Step-by-step explanation:
I assume you are looking to solve for the value of b.
<u>3(b+2)</u> x <u>2</u>= <u>4b-10</u>
2 2 4
<u>6(b+2)</u> = <u>4b-10</u>
4 4
x 4 x4
6(b+2) = 4b-10
6b+12=4b-10
-4b -4b
2b+12=-10
-12 -12
<u>2b</u>=<u>-22</u>
2 2
b=-11
Answer:
written below for problem #2
Step-by-step explanation:
a. ratio is 12:40 since they're are 12 non fiction and 40 graphic novels
b. 40:12 (same reasoning as part a)
c. 6:40 for the ratio of science fiction to graphic novel, 12:6 for the ration of non fiction to science fiction, x:6 for the ratio of the unknown amount of fiction books to the science fiction books. (x is just there as a variable so it just represents fiction books)
