Answer:
"The relationship is proportional."
"The relationship is proportional."
"The equation of the line is y = -3x"
Step-by-step explanation:
First, a proportional relationship can be written as:
y = k*x
where k is called the constant of proportionality. (or the slope)
You can see that if we take x = 0, we have
y = k*0 = 0
Then this type of line always passes through the point (0, 0).
And in the graph you can see that this line does that, then:
"The relationship is proportional." is true.
We also can see that as x increases, the value of y decreases, this must imply that k is a negative number, then:
"The slope is negative." is true.
To find the value of the slope, we can take two points that belong to the line.
I will choose:
(0, 0) and (2, -6)
For the slope, we just take the quotient between:
Δy = -6 - 0 = -6 (the difference in the y-components)
Δx = 2 - 0 = 2 (the difference in the x-components)
the slope is:
k = Δy/Δx = -6/2 = -3
Then the slope is -3, and we can write the equation as:
y = -3*x
Then:
"The equation of the line is y = -3x" is true.

You have $90 and your brother has $120. You are saving $18 per week
and your brother is saving $15 per week. How many weeks will it take for
you and your brother to have the same amount of money saved? *
10 weeks
1 week
5 weeks
12 weeks
Answer:
10 weeks
Step-by-step explanation:
Let's set an equation for you and your brother.
You have $90 plus $18 for every week you save (x).
90+18x
And your brother has $120 plus $15 dollars per week that he saves (x)
120+15x
You want to have the sum of the money equal so combine the two concluded statements
90+18x=120+15x
Arrange them so that you have like terms on each side
90+18x-15x=12+15x-15x
90+3x=120
90-90+3x=120-90
3x=30
x=10
"x" is our number of weeks you and your brother save so the answer is 10 weeks
Just to be sure you can use our equation and plug 10 for every time you see x to make sure our answer is right.
A blockbuster movie makes about $352,000,000 in the United States during its
opening weekend. That same weekend another movie opens but only makes
about $4,800,000
Write each dollar amount in a scientific notation
Answer:
$3.77 * 10^7
Step-by-step explanation:
$35,200,000 + $2,500,000 = $37,700,000 = $3.77 * 10^7
Answer:
3.52×10^84.8×10^6Step-by-step explanation:
Converting numbers into scientific notation:
$352,000,000 = 3.52×10^8$4,800,000 = 4.8×10^6Find m∠MON
I have a hard time with theses
Answer:
m∠MON = 15°
Step-by-step explanation:
The given parameters are;
m∠LON = 77°
m∠LOM = 9·x + 44°
m∠MON = 6·x + 3°
By angle addition postulate, we have;
m∠LON = m∠LOM + m∠MON
Therefore, by substituting the known values, we have;
∴ 77° = 9·x + 44° + 6·x + 3°
77° = 9·x + 44° + 6·x + 3° = 15·x + 47°
77° = 15·x + 47°
77° - 47° = 15·x
15·x = 77° - 47° = 30°
15·x = 30°
x = 30°/15 = 2°
x = 2°
Given that m∠MON = 6·x + 3° and x = 2°, we have;
m∠MON = 6 × 2° + 3° = 12° + 3° = 15°
m∠MON = 15°.

What is the equation of the line that passes through the point (4,−2) and has a slope of -2
Answer:
y = -2x + 6
Step-by-step explanation:
Point slope form is y - y1 = m(x-x1)
y - (-2) = -2(x-4)
y + 2 = -2x + 8
y = -2x + 6

A roller coaster can hold 32 people at a time. There are 275 people waiting to ride the roller coaster. How many trips will the roller coaster have to make for all the people to ride?
Answer:
9
Step-by-step explanation:
275 divided by 32 in equal to 8.59, so you just have to round up but that last trip just wont be full
Answer:
9 roller coaster rides. hope this helps!
Step-by-step explanation:
A roller coaster can hold 32 people at a time.
there are 275 people waiting in line.
How many trips will it take for there to be 0 people waiting in line?
We know the roller coaster can hold 32 people at a time, and 275 people are waiting in line.
275/32=8 rides and 19 people left.
If you don't know how to do that: 275 people at first. 275-32 because the roller coaster can only hold 32. Repeat that process untill you find your answer.
So we have 8 rides, and 19 people left? It doesn't matter, It will not take, half the time left, or more time to get it done. So anything below or equal to 32 people will take the same amount of time. So our final answer is 9 rides. Not 8.59375.

Help solve equations by completing the square
[tex]x^2+10x+22=13\\x^2+10x+22-13=0\\x^2+10x+9=0\\[/tex]
Now completing the square.
[tex](x^2+10x)+9=0\\(x^2+10x+25)+9-25=0\\(x+5)^2-16=0\\(x+5)^2=16[/tex]
(x+5)² = 16 is the rewritten equation... For first question btw.
For the solutions to the equation -
[tex]x+5=\sqrt{16},-\sqrt{16} \\x+5=4,-4\\x=4-5,-4-5\\x=-1,-9[/tex]
x = -1,-9 is the solution, for the second question.
Peter scored a total 44 points on 9 math quizzes. What score does Peter need on his tenth and final quiz in order to have a final quiz average of 5 ?
Answer:
Number of points need = 6 points
Step-by-step explanation:
Given:
New average = 5
Points peter has = 44
Total quiz play = 9
Find:
Points required for average of 5
Computation:
Total number of match = 9 + 1
Total number of match = 10
Average points = 5
Assume;
Number of points need = x
So,
Average points = [Total points] / Total number of match
5 = [44+x] / 10
50 = 44 + x
x = 6
Number of points need = 6 points
The score does Peter needs on his tenth and final quiz in order to have a final quiz average of 5 is 6 and this can be determined by using the formula of average.
Given :
Peter scored a total of 44 points on 9 math quizzes.
The following steps can be used in order to determine the score of the tenth quiz:
Step 1 - The formula of average can be used in order to determine the score of the tenth quiz.
Step 2 - According to the given data, Peter scored a total of 44 points on 9 math quizzes. Now, let the score of the final tenth quiz be 'x'.
Step 3 - The average of the 10 quizzes is given by:
[tex]\dfrac{44 + x }{10}=5[/tex]
Step 4 - Simplify the above expression in order to determine the value of 'x'.
50 = 44 + x
x = 6

Answer:
The answer is 50 degrees
Step-by-step explanation:
The small box at the corner of the triangle indicates that the triangle is exactly 90 degrees, or a right angle. In order to solve the expression, you would need to do 40 + x = 90, which would be x = 50
Answer:
It should be 40 degrees, If you have a protractor, you could measure it.
Step-by-step explanation:
I think it's 40 degrees because if you fold it in half, it would probably match.
