Answer:
C.
Since the square root of 20 is around 4.5, we know that ≈4.5 is almost at the half mark between 4 and 5 on the number line.
Answer:
according to what I was taught
Step-by-step explanation:
the first step to solving rational inequalities is to find the zeros. Because a rational expression consists of the ratio of two polynomials, the zeroes for both polynomials will be needed.

Step-by-step explanation:
The highest degree is ![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
quadratic equations are usually in this form:
+bx +c =0 (the signs may be positive or negative depending on the question given)
Answer:
D) x=-3, y=-7
Step-by-step explanation:
9x - 7y = 22
x + 3y= -24
9x - 7y = 22
x= -24-3y
9(-24-3y)-7y=22
x= -24-3y
-216-27y-7y=22
x= -24-3y
-34y=22+216
x= -24-3y
-34y=238
x= -24-3y
y=238/(-34)
x=-24-3y
y=-7
x=-24-3*(-7)
y=-7
x=-24+21
y=-7
x=-3
(x,y)=(-3,-7)
