Answer:
C)
region C
Step-by-step explanation:
We have to use what is called the zero-interval test [test point] in order to figure out which portion of the graph these inequalities share:

0 ≤ 2 ☑ [We shade the portion of the graph that CONTAIN THE ORIGIN, which is the bottom portion.]

0 ≥ −3 ☑ [We shade the portion of the graph that CONTAINS THE ORIGIN, which is the left side.]
So, now that we got that all cleared up, we can tell that both graphs share a region where the ORIGIN IS VISIBLE. Therefore region C matches the above inequalities.
I am joyous to assist you anytime.
Sometimes it helps to draw it out...

21
therefore, CM + MQ = CQ
17 + MQ = 21
MQ = 21 - 17
MQ = 4 <===
Answer:
The length is 10 cm
Step-by-step explanation:
The area is given by length times width
A = l*w
We have an area of 80 cm^2 and a width of 8
80 = l*8
Divide each side by 8
80/8 = 8l/8
10 = l
The length is 10 cm
Y - 2 / 4
I don't really know how to explain it, but y - 2 / 4 is equivalent to 1/4y - 1/2
