57=-3(m+5)+m
Answer:
M=-36
Step-by-step explanation:
Answer:
m = - 36
Step-by-step explanation:
57=−3(m+5)+m
57=−3(m+)+m
57=(−3)(m)+(−3)(5)+m(
57=−3m+−15+m
57=(−3m+m)+(−15)(
57=−2m+−15
57=−2m−15
−2m−15=57
−2m−15+15=57+15
−2m=72 div 2

Mikayla went on a road trip. Two hours into the road trip, she had 15 gallons of gas in her tank. Seven hours into her trip, she had 3 gallons of gas in her tank. Find the rate of change
Answer: -2.4 gallons per hour
Step-by-step explanation:
Think of this as a linear equation where the rate of change is m.
m = (Y₂ - Y₁) / (X₂ - X₁)
Assume the points are: (2, 15) (7, 3)
m = (3 - 15) / (7 - 2)
= (-12) / 5
= - 2.4 gallons per hour
Gas is reducing by 2.4 gallons per hour.

[tex]8 \sqrt{5} is \: the \: length[/tex]
Step-by-step explanation:
[tex]( {16})^{2} = ( {x})^{2} - ( {8})^{2} \\ 256 = {x}^{2} - 64 \\ 256 + 64 = {x}^{2} \\ \sqrt{320} = \sqrt{ {x}^{2} } \\ 8 \sqrt{5} = x[/tex]
The graph of a polynomial function is shown. Which statement about the polynomial is true?
Answer:
The degree is odd and the leading coefficient is positive.
Step-by-step explanation:
Clearly from the graph of the polynomial function we see that both the ends of the graph are in the opposite directions.
This means that the degree of the polynomial is odd.
( Since in even degree polynomial both the ends are in the same direction )
Also, the leading coefficient of the polynomial is positive.
Since, when a leading coefficient of a odd degree polynomial let p(x) is positive then it satisfies the following property:
when x → -∞ p(x) → -∞
and when x → ∞ p(x) → ∞

Answer:
[tex]\sqrt{10}[/tex]
Step-by-step explanation:
This is a 45-45-90 triangle whose leg to hypotenuse ratio is 1 / [tex]\sqrt{2}[/tex]
so I set up a proportion of 1 / [tex]\sqrt{2}[/tex] = x / 2 [tex]\sqrt{5}[/tex]
cross-multiply to get [tex]\sqrt{2}[/tex]x = 2[tex]\sqrt{5}[/tex]
x = 2[tex]\sqrt{5}[/tex] / [tex]\sqrt{2}[/tex] and multiply numerator and denominator by [tex]\sqrt{2}[/tex], this is called rationalizing the denominator
lets do
[tex]\\ \sf\longmapsto \sqrt{2}x=2\sqrt{5}[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{2\sqrt{5}}{\sqrt{2}}[/tex]
[tex]\\ \sf\longmapsto x=\sqrt{2}\sqrt{5}[/tex]
[tex]\\ \sf\longmapsto x=\sqrt{2(5)}[/tex]
[tex]\\ \sf\longmapsto x=\sqrt{10}[/tex]

In ΔJKL, k = 4.1 cm, j = 3.8 cm and ∠J=63°. Find all possible values of ∠K, to the nearest 10th of a degree.
Given:
In ΔJKL, k = 4.1 cm, j = 3.8 cm and ∠J=63°.
To find:
The value of ∠K to the nearest 10th of a degree.
Solution:
According to the Law of Sine:
[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]
We have, In ΔJKL, k = 4.1 cm, j = 3.8 cm and ∠J=63°.
Using the Law of Sine, we get
[tex]\dfrac{j}{\sin J}=\dfrac{k}{\sin K}[/tex]
[tex]\dfrac{3.8}{\sin (63^\circ)}=\dfrac{4.1}{\sin K}[/tex]
[tex]3.8\sin K=4.1\sin (63^\circ)[/tex]
[tex]\sin K=\dfrac{4.1\sin (63^\circ)}{3.8}[/tex]
[tex]\sin K=0.961349[/tex]
[tex]K=\sin^{-1}(0.961349)[/tex]
[tex]K=74.0182[/tex]
[tex]K\approx 74.0[/tex]
Therefore, the measure of angle K is 74.0 degrees.

ok answer this, 7x150+10 and that should be your answer.
Answer:
x=20
Step-by-step explanation:
there are two intersecting lines with two pairs of opposite angles each of the pairs are called vertical angles and if two angles are vertical, they are congruent
we know the angles are congruent, we also know (150=7x+10) and in order to solve for x we have to isolate x by subtracting 10 to both sides giving us (140=7x )
divide by seven on both sides to isolate x and that will give you x=20.

A regular pentagon and an equilateral triangle have the same perimeter. The perimeter of the pentagon is 5(x-2) inches. The perimeter of the triangle is 4(1/2x+2) inches. What is the perimeter of each figure?
Answer:
20 inches.
Step-by-step explanation:
We equate the perimeters:
5(x - 2) = 4(1/2x + 2)
5x - 10 = 2x + 8
5x - 2x = 8 + 10
3x = 18
x = 6
The perimeters = 5(6-2)
= 20 inches.

Answer:
n the immediate aftermath of a national election, exit polls offer the best glimpse of what the electorate looked like – who voted for whom and what seemed to drive their choices.
Traditionally, the exit polls have been a collaborative effort of a consortium of major media organizations, involving interviews with a representative sample of thousands of voters as they leave polling places across the nation. In this election, concerns about the pandemic helped drive an unprecedented number of Americans to vote early or by mail. By Nov. 3, more than 100 million Americans had already voted. To account for these voters, this year’s exit polls include data from telephone interviews with a representative sample of people who voted early or by mail. In all, the national exit poll includes interviews with 15,590 voters. It is important to note that these data will be updated, so the numbers below should be considered preliminary, reflecting the exit polls reported as of Nov. 4.
