Using the graph, determine the equation of the axis of symmetry.
Answer:
x = -5
Step-by-step explanation:
If one draws a perfect verticle line at x = -5, one will have exactly 1/2 the parabola on each side. Then is one where to fold the parabola on that line, then there would be no overhang. Hence x = -5 is the axis of symmetry.

In the diagram, wirich angle is part of a linear pair and
part of a vertical pair?
OZBFC
OZCFG
OZGFD
Ο LEFA
Answer:
∠EFA
Step-by-step explanation:
The diagram shows several rays starting at point F. There are 2 sets of rays that are opposite to each other ie their angles add up to 180°
These are
FD and FA
FB and FE
You can ignore the other two rays since they do not have any opposite rays and therefore do not figure in a linear relationship
Ignoring FG and FC we get the equivalent of two lines crossing each other at point F
We can eliminate any angles that contain C and G
So we can eliminate ∠BFC, ∠CFG and ∠GFD
Which leaves the last choice as the only option
So answer is ∠EFA
∠EFA is linearly paired with ∠BFD since they lie on the same straight line and the measure of sum of their angles is 180°
∠EFA also is vertically paired with ∠BFD since these angles are opposite each other

5.5x²-18x+12=0
The required answers for the given questions is question are 1) x = -4, 2) x = 6 - √15, 3) x = 3 + 3√3, 4) x = -3, and 5)x = -9 - √21 / 5
The quadratic Equation formula is x = -b ± √(b² - 4ac) / 2a
1. x² + 7x + 12 = 0
By using the above formula
Here a = 1, b = 7, c = 12
x = -7 ± √(7² - 4*1*12) / 2*1
x = -7 ± √(49 - 48) / 2
x = -7 ± √1 / 2
x = -7 ±1 /2
x = -7+1 /2 x = -7 - 1 / 2
x = - 6 / 2 x = -8 / 2
x = -3 x = -4
2) x²-12x+21=0
By using the above formula
Here a = 1, b = -12, c = 21
x = -(-12) ± √((-12)² - 4*1*21) / 2*1
x = 12 ± √(144 - 84) / 2
x = 12 ± √60 / 2
x = 12 ±2√15 /2
x = 12 + 2√15 /2 x = 12 - 2√15 / 2
x = 6 + √15 x = 6 - √15
3. 18+6y-y²=0
By using the above formula
Here a = -1, b = 6, c = 18
x = -6 ± √((6² - 4*(-1)*18) / 2*(-1)
x = -6 ± √(36 + 72) / -2
x = -6 ± √108 / -2
x = -6 ± 6√3 / -2
x = -6+6√3 /-2 x = -6 - 6√3 / -2
x = 3-3√3 x = 3 + 3√3
4. 3x²+14×+15=0
By using the above formula
Here a = 3, b = 14, c = 15
x = -14 ± √((14² - 4*(3)*15) / 2*(3)
x = -14 ± √(196 - 180) / 6
x = -14 ± √16 / 6
x = -14 ± 4 / 6
x = -14 + 4 /6 x = -14 - 4 / 6
x = -10 / 6 x = -18 / 6
x = -5/3 x = -3
5.5x²-18x+12=0
By using the above formula
Here a = 5, b = -18, c = 12
x = -18 ± √((18² - 4*(5)*12) / 2*(5)
x = -18 ± √(324 - 240) / 10
x = -18 ± √84 / 10
x = -18 ± 2√21 / 10
x = -18 + 2√21 /10 x = -18 - 2√21 / 10
x = -9 + √21 / 5 x = -9 - √21 / 5
Hence, the values of the given question are 1) x = -4, 2) x = 6 - √15, 3) x = 3 + 3√3, 4) x = -3, and 5)x = -9 - √21 / 5

Describe the set of nonnegative powers of 10 using the following.
(x | x = , n = 0, 1, 2, 3, …)
The set of non negative powers of 10 is given as
(x | x = 10ⁿ , n = 0,1,2,3....)
Powers of 10 is any integer powers of the number 10. In simple words 10 multiplied by itself several times.
We need to define a set of nonnegative powers of 10 using the given set builder notation .
Powers of 10 is expressed as = 10ⁿ where n = 0,1,2,....
Thus in set builder form we can write
(x | x = 10ⁿ , n = 0,1,2,3....) which states that x is such that (which is denoted as '|' ) x is equal to 10ⁿ where n is equal to 0,1,2,....

Ed Moura has $73000 invested in stocks paying 8%. How much additional money should he invest in certificates of
deposit paying 4% so that the average return on the two investments is 5%?
Answer:
The additional money that Ed Moura should invest in certificates of deposit paying 4% so that the average return on the two investments is 5% is 219,000.
Step-by-step explanation:
It is given that Ed Moura has $73,000 invested in stocks earning an average return of 8%, and that he should put the remaining funds in certificates of deposit paying an average return of 4%, the average return on the two investments is 5%, than;
=> 0.08 (73,000) + 0.04b = 0.05 (b + 73,000)
=> 5840 + 0.04b = 0.05b + 3650
=> 0.01b = 2190
=> b = 219,000
=> $219,000
Therefore, the additional money that Ed Moura should invest in certificates of deposit paying 4% so that the average return on the two investments is 5% is $219,000.

Find an equation of the line that passes through the pair of points (-5, -9) and (2,-7)
Answer:
y=0.3x - 7.6
Step-by-step explanation:
line: y=ax+b
a= Δy ÷ Δx
a= (-9 + 7) ÷ (-5 - 2)
a= -2 ÷ -7 = approximately 0.3
y=0.3x + b
Now you can fill in one of the points to find b (or both to make sure you got the answer right).
0.3 × 2 + b = -7
0.6 + b = -7
b = -7 - 0.6 = approximately -7.6
So: an equation of the line that passes through this pair of points is y=0.3x - 7.6
