Step-by-step explanation:
When a polynomial f(x) is divided by (x - a) then remainder is f(a)
A
divided by (x + 4 ), then a = - 4
[tex](-4)^{4}[/tex] - 8(- 4)² + 16 = 256 - 128 + 16 = 144 ≠ 20
B
divided by (x - 2), then a = 2
3(2)³ + 7(2)² + 5(2) + 2
= 3(8) + 7(4) + 10 + 2
= 24 + 28 + 12 = = 64 ≠ 20
C
divided by (x + 5) , then a = - 5
(- 5)³ + 5(- 5)² - 4(- 5) + 6
= - 125 + 125 + 20 + 6 = 26 ≠ 20
D
divided by (x - 2), then a = 2
3[tex](2)^{4}[/tex] - 5(2)³ + 5(2) + 2
= 3(16) - 5(8) + 10 + 2
= 48 - 40 + 12 = 20 ← Remainder of 20

Step-by-step explanation:
Khloe needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 6 hours and charged her $59 for parts. The total was $749. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.
Answers
The cost of the labor per hour is $115.
The total amount that the technician charged her is the sum of the cost for the total hours worked and the costs of the parts.
Total charge = cost of total hours worked + cost of parts
$749 = $59 + cost of total hours worked
Cost of total hours worked = $749 - $59
Cost of total hours worked = $690.
In order to determine the cost per hour of labour, divide the total cost of total hours worked by the hours worked.
$690 / 6 = $115.

What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
In an auditorium, a charity show is conducted in order to raise at least $3,000.
The auditorium can accommodate up to 180 spectators.
Tickets cost $12 for students and $20 for adults.
Let x be the number of students and y be the number of adults. Then we have
x + y = 180
12x + 20y ≥ 3000
By solving, equations 1 and 2. Then we have

Which table represents a linear function?
Answers
Answer:Well, a linear function is proportional, a straight line (on a graph). And the numbers must not have the same answer. For instance, if the X input is 5, and the Y output is 7. And then another X input is 5, and the Y output is 8, that's non-linear.
So, the Answer would be the third graph. This is because the X values are steadily increasing, and so are the Y values.
For the X and Y values, for each time X increases by 1, Y increases by -8. This is, linear because both sides are constantly and evenly increasing.

Describe and correct the error in evaluating the expression. -10^2 = 100
Answers
Answer:
-10² = -100
Step-by-step explanation:
The error in the evaluation occurred when the negative base (which is -10) was squared altogether outside of the parenthesis. (-10²) still results in -100.
The only time that the result will produce a positive 100 is when you square -10 this way: (-10)² = 100 because the negative sign is included with the squaring of base through the parenthesis.
Hope this helps.

Solve z=sh/s+h for s
Answers
Answer:
[tex]\displaystyle s = \frac{hz}{h-z}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]\displaystyle z = \frac{sh}{s+h}[/tex]
And we want to solve it for s.
First, we can multiply both sides by the denominator:
[tex]\displaystyle z(s+h) = sh[/tex]
Distribute:
[tex]\displaystyle sz + hz = sh[/tex]
Subtract hz and sh from both sides:
[tex]\displaystyle sz - sh = -hz[/tex]
Factor:
[tex]\displaystyle s(z-h) = -hz[/tex]
And divide. Hence:
[tex]\displaystyle s = \frac{-hz}{z-h} = - \frac{hz}{z-h} = \frac{hz}{h-z}[/tex]
Any one of the above three forms are correct, although the third form is preferred because it omits the additional negative.

Multiply first cause it’s in the parentheses. To multiply fractions you go straight across
1/2 x 3/8
1 x 3 = 3
2 x 8 = 16
So you get
3/16
When dividing fractions you have to flip the second fraction and multiply the same.
So 3/4 divided by 3/16
Flip 3/16 to 16/3
So now
3/4 x 16/3
16 x 3 = 48
4 x 3 = 12
48/12
