D) y=x^2-3
ALSO if you have a kind heart (and want more points) i need help on this one https://brainly.com/question/17322049
Answer:
22.B) union
20.A) x+y=3^2
Step-by-step explanation:
22. The compound inequality [tex]1-4x < 21[/tex] and [tex]5x+2 > 22[/tex] is intersection, option A is correct.
21. [tex]x+y=3^2[/tex] is not a function. Option A is correct.
22. The compound inequality [tex]1-4x < 21[/tex] and [tex]5x+2 > 22[/tex] is an example of a compound inequality involving "and."
Both inequalities need to be satisfied simultaneously for the compound inequality to be true.
Hence, the compound inequality is intersection.
21. A function is a relationship between two variables in which each input value (x) corresponds to exactly one output value (y).
In this case, the equation [tex]x+y=3^2[/tex] does not represent a clear relationship between x and y.
[tex]x+y=3^2[/tex] represents a curve in the xy-plane rather than a function.
Hence, [tex]x+y=3^2[/tex] is not a function.

what is the slope-intercept form of (-2,1) and (4,6)
Answer:
y = [tex]\frac{5}{6}[/tex] x + [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (4, 6)
m = [tex]\frac{6-1}{4+2}[/tex] = [tex]\frac{5}{6}[/tex] , thus
y = [tex]\frac{5}{6}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (4, 6 ), then
6 = [tex]\frac{20}{6}[/tex] + c ⇒ c = 6 - [tex]\frac{20}{6}[/tex] = [tex]\frac{16}{6}[/tex] = [tex]\frac{8}{3}[/tex]
y = [tex]\frac{5}{6}[/tex] x + [tex]\frac{8}{3}[/tex] ← equation of line

Maria's account has a credit of $ 13, and Harry's account has a debit of $ 14. Which of the following statements are true? Select that apply.
Select A Harry's account has $ 27 more than Maria's account. B Maria's account has $ 27 less than Harry's account. C Harry's account has $ 27 less than Maria's account. D Maria's account has $ 27 more than Harry's account.
PLEASE ANSWER FASTT!!
Answer:
A, Harry has $27 more.
Step-by-step explanation:
I could be wrong but.
1) debit cards are of your money, if you have $14 in your account it means you have $14 that you can spend without owing anything.
2) credit cards allow you to borrow money with the expectation that you pay it back. So if you have $13 of credit, you owe $13 which I guess could be seen as -$13.
3) the distance between -13 and 14 is 27.
Given: If X, then Y. If Y, then Z. Y is true. So: X is unknown, Z is unknown X is unknown, Z is true X is false, Z is true X is true, Z is true
The correct option that gives a proper logic for the argument that "If X, then Y. If Y, then Z. Y is true" is given by;
Option B; X is unknown, Z is true
This question is based on the principles of logic. Logic helps us distinguish between valid and invalid arguments.Now, the argument here is that;If X, then Y. If Y, then Z. Y is true.
Now, from this argument, we can see that Y depends on X and then Z depends on Y.Now, we are told that Y is true. Since Z depends on Y as seen that If Y, then Z, we can say that Z is also true.However, we can't say anything about X as X is unknown.

Chose all the values of x that are not in the domain of this rational function. Picture attached, 15 points and I'll give Brainliest! Due in two hours. A. -2 B. 1 C. 2 D. o
Answer:
All of them.
Step-by-step explanation:
For rational functions, the domain is all real numbers except for the zeros of the denominator.
Therefore, to find the x-values that are not in the domain, we need to solve for the zeros of the denominator. Therefore, set the denominator to zero:
[tex]x(x-1)(x^2-4)=0[/tex]
Zero Product Property:
[tex]x\neq 0\text{ or }x-1\neq 0\text{ or }x^2-4\neq 0[/tex]
Solve for the x in each of the three equations. The first one is already solved. Thus:
[tex]x-1\neq 0 \text{ or }x^2-4\neq 0\\x\neq 1\text{ or }x^2\neq 4\\x\neq 1 \text{ or }x\neq\pm 2[/tex]
Thus, the values that cannot be in the domain of the rational function is:
[tex]x=-2,0,1,2[/tex]
Click all the options.
Answer:
[tex]\Large \boxed{\mathrm{All \ options}}[/tex]
Step-by-step explanation:
The domain of a function are all possible values for x.
To find the domain of a rational function, we set the denominator equal to 0, and solve for x. Those values of x are not included in the domain, since the denominator of 0 would make the rational function undefined.
[tex]x(x-1)(x^2-4)=0[/tex]
Setting the factors equal to 0.
[tex]x=0 \\ \\ \\\\ x-1=0 \\ \\ x=1 \\ \\ \\ \\ x^2 -4=0 \\ \\ x^2 =4 \\ \\ x=\pm 2[/tex]
The values of x that are not in the domain of the rational function are x=-2, x=1, x=2, and x=0.

Answer: 11.) -6. 12.) 4/5
For the square roots, there should be a plus&minus sign but my keyboard doesn't have that.
13.) 3 14.) 8
explanation: For a square root, you are looking for a number that was multiplied by itself to become the number under the radical.
11 is a bit tricky since there is a negative sign before the radical. 6×6=36 -6 × -6 = 36. It seems they want only the -6 here.
4/5 ×4/5 = 16/25
For cube root, you need the number that is multiplied by itself three times. 3×3×3 = 27 8×8×8=512
Grayson works in a department store selling clothing. He makes a guaranteed salary of $350 per week, but is paid a commision on top of his base salary equal to 20% of his total sales for the week. How much would Grayson make in a week in which he made $925 in sales? How much would Grayson make in a week if he made xx dollars in sales?
Answer: 535
0.20x+350
Step-by-step explanation:
If Grayson makes $925 in sales he receives $535 and if he makes x sales then he receives $350 +0.2x
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here he makes a base income of $350 and he also earns 20% of his sales output and thus if he makes $925, his total income is
= 350+0.2×925
=$535
And let Grayson make x sales in one week then his salary will be
= 350+0.2x
Hence, If Grayson makes $925 in sales he receives $535 and if he makes x sales then he receives $350 +0.2x

Answer:
75.091
Step-by-step explanation:
d. x= -1 and y = -1
Is it perpendicular, neither, of parallel. Show work
Perpendicular.
x = -1 is a vertical line intersecting the x-axis at (-1, 0).
y = -1 is a horizontal line intersecting the y-axis at (0, -1).
Because these lines are both straight, they will eventually intersect at (-1, -1). They will also form 90° angles, the definition of perpendicular.

Answer:
13
Step-by-step explanation:
The mean of all the numbers is the sum of the numbers divided by the number of numbers.
The sum of all of the numbers is 10 + 14 + 16 + 12 + 14 + 14 + 11 = 91.
We then divide by 7, getting 13.
Answer:
13
Step-by-step explanation:
The mean of a data set is the average value of the set.
To find the average, we simply need to add all the values and then divide by the number of values.
There are 7 values. So, add all of them and then divide by 7.
[tex]\bar x=\frac{10+14+16+12+14+14+11}{7}[/tex]
Add:
[tex]\bar x=\frac{91}{7}[/tex]
Divide:
[tex]\bar x=13[/tex]
Therefore, our average is 13.
(Note that the x with the bar on the top is a common way to denote the mean.)
The regular price of a child's entry ticket to a water park is $8 less than that for an adult's. The park offers half off all entry tickets during the off-peak season. The Sandlers paid a total of $194 for 1 adult ticket and 4 child's tickets to the water park during the off-peak season. The following equation represents this situation, where x represents the regular price of an adult ticket:
194 = one-half x + 2(x − 8)
What is the regular price of a child's ticket? (5 points)
a
$68
b
$76
c
$84
d
$89
Answer:
76
Step-by-step explanation:
so first the equation for the situation has been given which is
194=1/2x + 2x - 16
now you can just solve since it's a linear equation
194=2.5x -16
take 16 to the other side to get
210=2.5x
solve to get x (adult price)
which is 84
remember the. child's price is 8 less
84-8=76
