These are vertical angles since they are opposite angles made by two intersecting lines. And vertical angles are congruent so we would set them equal to each other.
6x-19 = 3x + 32
Subtract 3x from both sides.
3x - 19 = 32
To isolate 3x on one side add 19 to both sides.
3x= 51
Divide by 3 on both sides.
X = 17

5. Miguel has an after-school job. He works
between 15 and 25 hours each week and is paid
$12 per hour. What is an appropriate domain for
this scenario?
A. All real numbers such that 15
B. All real numbers such that 180 < x < 300
C. All real numbers
D. All real numbers such that x>0
Answers
Answer:
The domain is 15 ≤ x ≤ 25
Step-by-step explanation:
The given parameters are;
The number of hours Miguel works each week = Between 15 and 25 hours
The amount he is paid per hour = $12
Therefore, we have;
The domain is all real numbers, 'x', such that 15 ≤ x ≤ 25
The amount Miguel makes each week, 'y' is between; 12 × 15 ≤ A ≤ 12 × 25
Therefore the range is 180 ≤ y ≤ 300.

Use Permutation Formula
difference between the median and mean scores.
Answers
Answer:
Mean = sum of the terms/ number of terms
Median is the middle number of the data
Step-by-step explanation:
Median is when you put all the numbers in order from least to greatest and then you find the number directly in the middle. If there are two numbers in the middle, you find the sum of the two numbers and divide by 2. In other words you find the mean of it, but that’s only if there are two numbers in the middle.

Kate has a coin collection. She keeps 7 of the coins in a box which is only 5% of her entire collection.
Answers
Answer:
She has 140 coins in total.
Step-by-step explanation:
Since 7 coins is only 5% of the entire collection, 7 coins=5%. 100% is the total. So first you need to divide 100 by 5 which is 20 (100÷5=20). Next, you need to multiply 20 by 7 (20×7=140) to find out how much coins she has in total.

What is the horizontal asymptote of j (x) = StartFraction 14 x cubed + 45 Over 2 x cubed + x + 9 EndFraction
Answers
Answer:
C. y=7
Step-by-step explanation:
guy above me was right
The horizontal asymptote of the given function [tex]f(x) = \dfrac{14x^{3} +45}{2x^{3}+x+9}[/tex] would be y = 7.
When do we get horizontal asymptote for a function?The line y = a is a horizontal asymptote if the function f(x) tends to 'a' from the upside of that line y = a, or from downside of that line.
The given function is
[tex]f(x) = \dfrac{14x^{3} +45}{2x^{3}+x+9}[/tex]
We need to determine the horizontal asymptote.
Horizontal asymptote;
From the given function, it is obvious that the denominator's degree is smaller than the numerator's degree.
Then, the horizontal asymptote is the y-axis.
Thus, the horizontal asymptote is y = 7.

O 68, 14, 3
0 7, 14, 3
Answers
Answer:
O 68, 14, 3
Step-by-step explanation:
Given:
f(x) = 4x² - x
When x = -4
f(x) = 4x² - x
= 4(-4)² - (-4)
= 4(16) + 4
= 64 + 4
f(x) = 68
When x = 1
f(x) = 4x² - x
= 4(1)² - 1
= 4(1) - 1
= 4 - 1
f(x) = 3
When x = 2
f(x) = 4x² - x
= 4(2)² - 2
= 4(4) - 2
= 16 - 2
f(x) = 14
The answer = 68, 3, 14

In order to help students improve their reading, a school district decides to implement a reading program. It is to be administered to the bottom 5% of the students in the district, based on the scores on a reading achievement exam. If the average score for the students in the district is 122.6, find the cutoff score that will make a student eligible for the program. The standard deviation is 18. Assume the variable is normally distributed. Round to two decimal places.
Answers
Answer:
92.99
Step-by-step explanation:
Mean, μ = 122.6
Standard deviation, σ = 18
Recall :
Z = (x - μ) / σ
x = score
The Zscore for the lower 5% = 0.05
Using, invnorm(0.05) = - 1.645
Put Z = - 1.645
-1.645 = (x - 122.6) / 18
-1.645 * 18 = x - 122.6
-29.61 = x - 122.6
-29.61 + 122.6 = x
x = 92.99
Suppose that AKL M is isosceles with base MK.

(3x +36)
(4x +31).
Х
Answers
Answer:
m<K = 51°
m<L = 78°
m<M = 51°
Step-by-step explanation:
Base angles of an isosceles ∆ are equal to each other, therefore,
m<M = m<K
Substitute
3x + 36 = 4x + 31
Collect like terms and solve for x
3x - 4x = -36 + 31
-x = -5
Divide both sides by -1
x = 5
Let's find each degree measure using the value of x
m<K = 4x + 31
Plug in the value of x
m<K = 4(5) + 31
m<K = 20 + 31
m<K = 51°
m<M = 3x + 36
= 3(5) + 36
= 15 + 36
m<M = 51°
m<L = 180° - (m<M + m<K) (sum of triangle theorem)
Substitute
m<L = 180 - (51 + 51)
m<L = 78°
