KL=9x+3
JL = 55, and
JK = 7x +4,
Find KL.
Answer:
30
Step-by-step explanation:
JL comprises of JK & KL. So ,
JL = JK + KL
Here the length of :-
KL= 9x + 3
JL = 55
JK = 7x + 4
So putting all the values above gives ,
7x + 4 + 9x + 3 = 55
=> 16x + 7 = 55
=> 16x = 55 - 7
= 48
=> x = 48/16 = 3
Using the value of x in finding the length of KL ,
KL = 9 × 3 + 3 = 27 + 3 = 30

Hey! I've had the same quiz earlier and these answers below are correct. Hope this helps you out and have a great day :)
We have proved that m∠ABC is an obtuse angle.
m∠ABC = m∠ABD + m∠DBC
100° = 60° + 40°
Given,
m∠ABD = 60°
m∠DBC = 40°
We need to prove that m∠ABC is an obtuse angle.
What is an obtuse angle?The angles greater than 90 degrees but less than 180 degrees are called obtuse angles.
We have,
From the figure.
m∠ABD = 60°
m∠DBC = 40°
We see that
m∠ABC = m∠ABD + m∠DBC
m∠ABC = 60° + 40°
m∠ABC = 100°
m∠ABC is greater than 90 degrees and less than 180 degrees so,
m∠ABC is an obtuse angle.
Thus we have proved that m∠ABC is an obtuse angle.

Step-by-step explanation:
A study of class attendance and grades among first-year students at a state university showed that in general students who attended a higher percent of their classes earned higher grades. Class attendance explained 81% of the variation in grade index among the students. What is the numerical value of the correlation between percent of classes attended and grade index
Answer:
r = 0.9
Step-by-step explanation:
Correlation is denoted by r. r² is usually used to measure variation along the line as a fraction of the total variation.
We are told class attendance explained 81% of the variation in grade index among the students. Thus, for this regression, the variation is;
r² = 81%
Or r² = 0.81
Thus, the numerical value of the correlation r would be;
r = √0.81
r = 0.9

Answer:
-2 (6x - y) = -12x + 2y
Step-by-step explanation:
By using the distributive property, you start by multiplying -2 and 6x which gets you -12x. You then multiply -2 and -y (in other words -y = -1y) so, -2* -y would get you 2 as a negative multiplied by a negative is a positive. So, adding them together would get your final answer: -2 (6x - y) = -12x + 2y

Jennie is paid $10 an hour for regular time work and $20 an hour for overtime
work what is Jennie's gross pay for a week in which she works 22 regular time
hours and 4 V overtime hours? (1 point)
Answer:
Jennie earned $300
Step-by-step explanation:
We are already given the amount of time that she works and the rate. We just need to multiply the time by the corresponding rate. She worked 22 regular hours and gets $10 for each one. That means she earned $220 just from the regular hours.
Now we need to add the overtime hours. She worked 4 hours and made $20 for each one. In total, that's $80.
220+80=300
Jennie earned $300

What is a function?
A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
The given function [tex]y = 2 -\sqrt{x+1}[/tex] and the point are ( x, -1.24 ). Put y = -1.24 in the given equation to get the value of x.
[tex]y = 2 -\sqrt{x+1}[/tex]
[tex]-1.24 = 2 - \sqrt{x+1}\\-1.24 - 2 = \sqrt{x+1}\\-3.24 = \sqrt{x+1}[/tex]
Squaring on both sides.
[tex](-3.24)^2 = (\sqrt{x+1})^2[/tex]
10.5 = x + 1
x = 9.5
Hence, the correct option is D.

Solve the system below by substitution.
6x - y=-23
2x +5 y = -13
(-3,2)
(-4,-1)
(5,4)
(-4,1)
Answer:
[tex](-4, -1)[/tex]
Step-by-step explanation:
[tex]6x-y=-23[/tex]
Add y to both sides:
[tex]6x-y+y=-23+y\\6x=-23+y[/tex]
Divide both sides by 6:
[tex]\frac{6x}{6}=-\frac{23}{6}+\frac{y}{6}\\x=\frac{-23+y}{6}[/tex]
Substitute this into the second equation given:
[tex]2*\frac{-23+y}{6}+5y=-13[/tex]
[tex]\frac{-23+16y}{3}=-13[/tex]
Multiply both sides by 3:
[tex]-23+16y=-39[/tex]
Add 23 to both sides:
[tex]-23+16y+23=-39+23\\16y=-16[/tex]
Divide both sides by 16:
[tex]\frac{16y}{16}=\frac{-16}{16}\\y=-1[/tex]
We know that [tex]x=\frac{-23+y}{6}[/tex].
Thus, [tex]x=\frac{-23-1}{6}[/tex]
[tex]x=-4[/tex]
[tex](x, y) = (-4, -1)[/tex]

How do you do this question?
Answer:
0.488
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
Here, n = 3 and p = 0.2.
The complement of at least 1 is at most 0.
P(r ≥ 1) = 1 − P(r = 0)
P(r ≥ 1) = 1 − ₃C₀ (0.2)⁰ (0.8)³⁻⁰
P(r ≥ 1) = 1 − (0.8)³
P(r ≥ 1) = 0.488
