Please help me. I'm stuck on question C. I've tried 1 or -1 so please tell me what's wrong with that. Thank you.
Answer:
In the first two parts you have filled in the table and found the correct graph of the function y = x² - x - 2, which is C.
Now, to solve for part C, you need to consider y = 3 value on the graph C.
Corresponding points on x-axis are the points you are looking for.
The points are:

what is the numerical expression of eight to the fourth power increased by six
Answer:
8^4 + 6
Step-by-step explanation:
we know it is an expression so there should be no equal sign and the write eight to the fourth power increased by six in numbers.
You get: 8^4 + 6
What factors of 25 have the sum of -24
Answer:
Factors of 25 are the numbers, which gives the result as 25 when multiplied together in pair of two. When we divide a number by one of its factors, then the resultant quotient is a whole number. The factors of 25 can be represented in positive as well as in negative form, but it cannot be a decimal or fraction. Similarly, the pair factors of 25 can also be represented in positive and negative form. For example, the pair factor of 25 can be (1, 25) or (-1, -25). If we multiply a pair of negative numbers, such as multiplying -1 and -5, it will result in 25 so there is no sum that will equal to -24
Subtract: (4x3 + 9xy + 8y) – (3x3 + 5xy – 8y)
(4x³ + 9xy + 8y) - (3x³ + 5xy - 8y) =
= 4x³ + 9xy + 8y - 3x³ - 5xy + 8y =
= 4x³ - 3x³ + 9xy - 5xy + 8y + 8y =
= x³ + 4xy + 16y ← the end answer

When y is 8.5 what value of X makes the equation true
Answer:
When X is = 8.5
Step-by-step explanation:
This is because for an equation to be equal, both side must be the same. So in other for X to be equal to Y, both must have the same value.
What is the reciprocal, multiplicative inverse of -14/15

-3x + 6y = 18
-3x = 6y+14
a) What is the slope of the 1st equation?
b) What is the slope of the 2nd equation?
c) Are they parallel, perpendicular, or neither?
Step-by-step explanation:
-3x + 6y = 18
-3x = 6y+14
a) the slope of the 1st equation = -(-3)/6 = ½
b) the slope of the 1st equation = -3/6 = -½
c) they are niether parallel nor perpendicular
Answer:
a) ¹/₂
b) -¹/₂
c) neither
Step-by-step explanation:
Slope-intercept form of a linear equation:
[tex]y=mx+b[/tex]
where:
m is the slopeb is the y-interceptGiven equations:
[tex]\begin{cases}-3x+6y=18\\-3x=6y+14 \end{cases}[/tex]
To find the slopes of the given equations, rearrange them to make y the subject then compare with the slope-intercept formula:
Equation 1
[tex]\begin{aligned}-3x+6y & = 18\\6y & = 3x + 18\\y & = \dfrac{3x+18}{6}\\\implies y & = \dfrac{1}{2}x+3\end{aligned}[/tex]
Therefore, the slope of Equation 1 is ¹/₂.
Equation 2
[tex]\begin{aligned}-3x & = 6y+14\\6y & = -3x-14\\y & = \dfrac{-3x-14}{6}\\\implies y& = -\dfrac{1}{2}x-\dfrac{14}{6}\end{aligned}[/tex]
Therefore, the slope of Equation 2 is -¹/₂.
Parallel slopes have the same slope.
Perpendicular slopes are at right angles to each other and therefore the product of their slopes is -1 (negative reciprocals of each other).
Therefore, the slopes of Equation 1 and Equation 2 are neither parallel or perpendicular.

69. The O'Brien's had $400.0 in a special
checking account for installment payments.
After paying $40.00 a month for three months
and $20.00 a month for two months. How
much was left in the account?
Hello :D
$40.00 x 3 = $120.00
$20.00 x 2 = $40.00
$120.00 + $40.00 = $160.00
$400.00 - $160.00 = $240.00
There is $240.00 left in the account.
A motorboat travels 448 kilometers in 8 hours going upstream and 440 kilometers in 5 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
9514 1404 393
Answer:
boat: 72 km/hcurrent: 16 km/hStep-by-step explanation:
The speed difference between boat and current is the upstream rate:
(448 km)/(8 h) = 56 km/h
The sum of speeds of boat and current is the downstream rate:
(440 km)/(5 h) = 88 km/h
The rate of the boat is half the sum of these:
(56 +88)/2 = 72 . . . km/h
The rate of the current is half their difference:
(88 -56)/2 = 16 . . . km/h
The rate of the boat is 72 km/h; the rate of the current is 16 km/h.
Solve the following equation for aa. Be sure to take into account whether a letter is capitalized or not.
Y=-n^3+3/4a
Answer:
Since you state that capitalization is important, then we can see that it is not possible to solve the equation for F.
If that's correct, then the only point of this was that we need to pay attention to symbols when dealing with equations or expressions

Apartment A requires a $300 security deposit and costs $750 each month. Apartment B has a $500 security deposit and the monthly rent is $725. Write and solve an equation to find the number of months it will take for the total rental costs to be the same.
500- 300 = 200
750 - 725 = 25
200÷ 25 = 8
it will take them 8 months for the total rent to cost the same
Convert 8 2/3% into a decimal.
Answer:
the answer is = 0.08666666666
The decimal value of 8 2/3% is 866.677.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
8 2/3% into decimal.
So, 8 2/3%
= 26/3 %
= 26 /3 x 100
= 8.6666667 x 100
=866.6777

if 4 is added to the numerator of the fraction 2/5, what number must be added to the denominator to make the fraction equivalent to 1/2?
Answer:
7
Step-by-step explanation:
Let X be the number...
2+4/5+X=1/2
6/5+X=1/2
12=5+X
X=7
Answer:
7
Step-by-step explanation:
By adding 4 to the numerator 2, we get 6 / 5.
Since 1 / 2 = 0.5, we need to find a number that we can divide 6 by to get 0.5.
Since 0.5 is half of a unit, we just need to find a number which it's half is 6.
6 * 2 = 12 (meaning 6 is half of 12), so 6 / 12 = 0.5 meaning 6 / 12 it's equivalent to 1 / 2.
12 - 5 = 7, so we need to add seven to the denominator to make the fractions equivalent.
