Which equation represents a line which is parallel to the line y = 3x - 8x + y = 18x - 3y = -123x + y = 6y - 3x = 7
Answers
Parallel equations have the same slope. First, let's identify the slope of the given equation, which is in the slope-intercept form:
[tex]y=mx+b[/tex]Where m is the slope and b is the y-intercept.
Comparing the given equation with this form, we have m = 3, so the slope is 3.
Now, let's identify the slope of each option:
[tex]\begin{gathered} x+y=18\\ \\ y=-x+18\\ \\ m=-1 \end{gathered}[/tex][tex]\begin{gathered} x-3y=-12\\ \\ 3y=x+12\\ \\ y=\frac{1}{3}x+4\\ \\ m=\frac{1}{3} \end{gathered}[/tex][tex]\begin{gathered} 3x+y=6\\ \\ y=-3x+6\\ \\ m=-3 \end{gathered}[/tex][tex]\begin{gathered} y-3x=7\\ \\ y=3x+7\\ \\ m=3 \end{gathered}[/tex]Therefore the correct option is the fourth one: y - 3x = 7.

since the polygon exterior angle is 45
the interior angle is

Answers
Explanation:
To find the equation, we first need to calculate the slope of the line. So, we can calculate the slope of the equation as follows:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Where (x1, y1) and (x2, y2) are two points in the line. So, replacing (x1, y1) by (5, -1) and (x2, y2) by (-5, 2), we get:
[tex]m=\frac{2-(-1)}{-5-5}=\frac{2+1}{-10}=\frac{3}{-10}=-\frac{3}{10}[/tex]Now, the equation of the line can be found as:
[tex]y-y_1=m(x-x_1)[/tex]Then, replacing the slope by -3/10 and (x1, y1) by (5, -1), we get:
[tex]undefined[/tex]Yolanda received 5/8 of the 72 votes cast for class secretary. How many votes did she receive?
Answers
The number of votes Yolanda received is equal to 45.
Number of votes Yolanda received = 5/8 of the total votes
total number of people who voted = 72
Thus to find the number of people who voted for her
we simply need to multiply the given fraction of votes by the total number of votes;
thus number of votes Yolanda received = 5/8 X 72
This implies the number of votes yolanda received = 5 X 9
which is equal to 45 votes
Thus from above we can conclude that Yolanda received 45 votes out of the 72 votes.

The following function represents the amount of money that Alisha has saved after w weeks:f(w)=20w+50A. What does the 20 represent in this situation?B. What does the 50 represent in this situation?C. How long would it take for Alisha to save $150?
Answers
The Solution:
Given that the function below represents the amount that Alisha saved after w weeks.
[tex]f(w)=20w+50[/tex]A.
The 20 represents the rate of change of Alisha's savings per week. That means it represents the amount by which Alisha's savings change from one week to another.
B.
The 50 represents the initial amount in Alisha's savings. That is, the amount in Alisha's saving at zero weeks.
C.
This means that we should find w when f(w)=$150
[tex]\begin{gathered} f(w)=20w+50 \\ f(w)=150,\text{ Substituting we get} \\ 150=20w+50 \end{gathered}[/tex]Collecting the like terms, we get
[tex]\begin{gathered} 150-50=20w \\ 100=20w \\ \text{Dividing both sides by 20, we get} \\ \frac{100}{20}=\frac{20w}{20} \\ \\ 5=w \\ w=5\text{ w}eeks \end{gathered}[/tex]Thus, it will take Alisha 5 weeks to save $150.

Answers
Given the function :
[tex]h(t)=-8t+1000[/tex]Where : h is the number of gallons and t is the number of hours
y - intercept is the value of h when t = 0
So, when t = 0
[tex]h(0)=-8\cdot0+1000=1000[/tex]So, y - intercept = 1000
And it represents the number of gallons at the beginning , which mean the tank is full with its 1000 gallons

Answers
Answer
Jennifer can perform 10 Routine Physicals in the morning
Solution
- The question tells us that Jennifer works 3 1/2 hours each morning and we are asked to find how many Routine physicals she can perform in the morning if 1 Routine physical takes 1/3 hours.
- In order to find the number of Routine physicals that can be performed in 3 1/2 hours, we simply need to assume that Jennifer can perform n number of Routine physicals. That is:
[tex]\begin{gathered} \text{ Total number of Routine physicals:} \\ \frac{1}{3}+\frac{1}{3}+\frac{1}{3}+\cdots=n\times(\frac{1}{3}) \\ \text{ } \\ \text{ If we take this as the total number of Routine Physicals possible within }3\frac{1}{2}\text{ hours, and r is the number } \\ \text{ of minutes left before }3\frac{1}{2}\text{ hours are completed, we have:} \\ \\ \frac{1}{3}+\frac{1}{3}+\frac{1}{3}+\cdots+r=3\frac{1}{2}=\frac{(3\times2)+1}{2}=\frac{7}{2} \\ \\ \therefore n\times(\frac{1}{3})+r=\frac{7}{2} \end{gathered}[/tex]Thus, to find the number of Routine Physicals, n, we simply make n the subject of the formula:
[tex]\begin{gathered} n=3(\frac{7}{2}-r) \\ \\ \text{This implies that the number of Routine Physicals is divisible by 3. This means that n is a multiple of 3} \\ \text{Thus, we can test values with multiples of 3.} \\ \\ \text{when n = 3:} \\ 3\times(\frac{1}{3})=1\text{hour} \\ \\ \text{when n= 6}\colon \\ 6\times(\frac{1}{3})=2\text{hours} \\ \\ \text{when n = 9:} \\ 9\times(\frac{1}{3})=3\text{hours} \\ \\ \text{when n= 12:} \\ 12\times(\frac{1}{3})=4hours \\ \\ \text{This implies that the number of Routine Physicals cannot be greater than or equal to 12. It also } \\ \text{implies that the number of Routine Physicals cannot be less than 9 since 9 physicals would take} \\ 3\text{ hours.} \\ \\ This\text{ means that the number of possible hours is between 10 or 11.} \\ \\ when\text{ n = 10:} \\ 10\times(\frac{1}{3})=3+\frac{1}{3}\text{ hours}<3\frac{1}{2}\text{ hours} \\ \\ \text{when n = 11:} \\ 11\times(\frac{1}{3})=3+\frac{2}{3}\text{ hours}>3\frac{1}{2}\text{ hours} \\ \\ \text{Thus, we can conclude that Jennifer can only do 10 Routine Physicals in the morning} \end{gathered}[/tex]Final answer

In order to solve this question it's useful to remember that the sum of the internal angles of a triangle is equal to 180°.
Firstly, let's take a look at the angles which have D as their vertex. These two angles are BDC and BDA and they both share a side whereas their remaining sides are in the same line. This means that these two are supplementary which means that their sum is equal to 180°. Knowing that the measure of BDC is equal to 90° we get:
[tex]\begin{gathered} BDC+BDA=90^{\circ}+BDA=180^{\circ} \\ 90^{\circ}+BDA=180^{\circ} \end{gathered}[/tex]If we substract 90° from both sides:
[tex]\begin{gathered} 90^{\circ}+BDA-90^{\circ}=180^{\circ}-90^{\circ} \\ BDA=90^{\circ} \end{gathered}[/tex]So both angles are right angles.
Having found the measure of angle BDA let's take a look at triangle BDA. We have a 45° angle, a 90° angle and angle b. Since the sum of these 3 must be equal to 180° so we get:
[tex]\begin{gathered} b+45^{\circ}+90^{\circ}=180^{\circ} \\ b+135^{\circ}=180^{\circ} \end{gathered}[/tex]Then we substract 135° from both sides:
[tex]\begin{gathered} b+135^{\circ}-135^{\circ}=180^{\circ}-135^{\circ} \\ b=45^{\circ} \end{gathered}[/tex]So we have found b. We still need to find a. Let's take a look at vertex B. The external angle is equal to 275° whereas there are two internal angles: a 45° angle and angle DBC. The sum of the external and internal angles in a vertex must be equal to 360° then we have:
[tex]\begin{gathered} 360^{\circ}=275^{\circ}+45^{\circ}+DBC=320^{\circ}+DBC \\ 360^{\circ}=320^{\circ}+DBC \end{gathered}[/tex]If we substract 320° from both sides we get:
[tex]\begin{gathered} 360^{\circ}-320^{\circ}=320^{\circ}+DBC-320^{\circ} \\ 40^{\circ}=DBC \end{gathered}[/tex]Now that we have angle DBC we can find angle a by looking at triangle BDC. The sum of its internal angles is 180° and we already know two of them: DBC and BDC. Then we get:
[tex]\begin{gathered} 180^{\circ}=DBC+BDC=40^{\circ}+90^{\circ}+a=130^{\circ}+a \\ 180^{\circ}=130^{\circ}+a \end{gathered}[/tex]Then if we substract 130° from both sides we get:
[tex]\begin{gathered} 180^{\circ}-130^{\circ}=130^{\circ}+a-130^{\circ} \\ a=50^{\circ} \end{gathered}[/tex]So now we know that a=50° and b=45°. Then a is bigger than b by 5° and the answer is option c.

We are given the following information from the image:
• m∠EGF = 31x + 3

We are required to determine the value of x.
We know that the angle subtended by the arc at the center of the circle is the angle of the arc. Therefore, we have:
[tex]\begin{gathered} m\angle EGF=31x+3 \\ m\angle EOF=192\degree \\ where\text{ }O\text{ }is\text{ }the\text{ }center\text{ }of\text{ }the\text{ }circle \end{gathered}[/tex]We also know that one of the circle theorems states that the angle subtended by an arc at the center is twice the angle subtended at the circumference. This becomes:
[tex]\begin{gathered} m\angle EOF=2\times m\angle EGF \\ 192\degree=2(31x+3) \\ 192\degree=62x+6 \\ 62x=192-6 \\ 62x=186 \\ \frac{62x}{62}=\frac{186}{62} \\ x=3 \end{gathered}[/tex]Hence, the value of x is 3.
