<span>1. Two angles are complementary. One angle measures 50°. What is the measure of the other angle?
</span>complementary, sum of the angles = 90
<span>
so 90 -</span> 50 = 40
<span>
answer is
C.40°
2.Two angles are supplementary. One angle measurement is 30° more than the other. What is the measure of the smaller angle?
</span>supplementary, sum of the angles = 180
One angle measurement is 30° more than the other.
so both angles are 75 and 105
105 is 30 more than the other angel of 75
answer
measure of the smaller angle is 75
so it's D.75°
<span>The correct answer is the Option "A": Integer. Then, the text is: "Whenever the solution to a system does not have integer coordinates, it can be difficult or impossible to find the precise answer through graphing."
By definition, the numbers called "Integers" are all the positive numbers (which are known as</span> <span>"Natural numbers"), all the negative numbers and the zero (0) and they are identified with the letter "Z":
Z= </span>{-∞...-3,-2,-1,0,1,2,3...+∞}<span>

Answer:
D. 4 is the non linear area of the graph.
Step-by-step explanation:
Non linear is when there is not a exact increase or decrease, also known as a equal change over time.
Answer:
I believe it is: B= 16.45
Answer:
At x = -2 the graph of this polynomial will touch the x-axis.
Step-by-step explanation:
Recall the behavior difference between power functions of even and odd power. Odd powers are associated with the crossing of the x-axis, while even powers are associated with "touching" of the x axis.
in this cases, since they give you the function in factor form, the actual roots (x-values where the function adopts value zero) of the function are evident :
It has a root at x = 5 [notice that at such x-value the factor (x-5) becomes zero], and this root is of multiplicity "3" (given by the power associated with the binomial factor for this root)
and has another root at x = -2 [notice that at such x-value the factor (x+2) becomes zero], and this root is of multiplicity "2" (given by the power associated with the binomial factor for it)
It is just the second root analyzed the one that shows an even power (2) associated to its binomial factor, and therefore it is at x= -2 that the graph of this function will show as "touching" the x axis.
