Answer:
y = -1/2 x
Step-by-step explanation:
slope = Δy / Δx
= 4 - 1 / -8 - (-2)
= 3 / -6
m = - 1/2
y = mx + b
1 = (-1/2)(-2) + b
1 = 1 + b
b = 0
eqn of the line : y = -1/2 x

If two angles are supplementary, then they are not congruent. Which diagram provides a counterexample for the statement?
A) A
B) B
C) C
D) D
Answer:
a
Step-by-step explanation:
supplmentay angles are either of two angles whose sum is 180°
option b is two right angles (90 degree on both) add them together you get 180.
option c is 60 degrees and 120 degrees add them together to get 180 degrees.
option d is 155 degrees and add 25 degrees you get 180.
so the answer is a, because 30 degrees and add the other 30 degrees together you only get 60
The correct answer is A, because 30 degrees and add the other 30 degrees together you only get 60.
What are supplementary angles?The supplementary angles are defined as the angles whose sum is equal to 180°.
Supplementary angles are either of two angles whose sum is 180°
Option b is two right angles (90 degrees on both) add them together you get 180.
Option c is 60 degrees and 120 degrees add them together to get 180 degrees.
Option d is 155 degrees and add 25 degrees you get 180.
Therefore, the answer is A, because 30 degrees and adding the other 30 degrees together you only get 60.

It is given that p varies inversely as q. If p = 12 and q = 45 find p, if q is 135.
Answer:
[tex]p =4[/tex]
Step-by-step explanation:
Given
Variation: Inversely
[tex]p = 12[/tex] when [tex]q = 45[/tex]
Required
Determine p when [tex]q = 135[/tex]
First, we need to determine the relationship between p and q
Since, it is an inverse variation.
The relationship is:
[tex]p\ \alpha\ \frac{1}{q}[/tex]
Convert to an equation
[tex]p= k *\frac{1}{q}[/tex]
[tex]p= \frac{k}{q}[/tex]
Where k = constant of variation
Make k the subject
[tex]k = p * q[/tex]
When [tex]p = 12[/tex] and [tex]q = 45[/tex]
[tex]k = 12 * 45[/tex]
[tex]k = 540[/tex]
To solve for p when q = 135
Substitute 135 for q and 540 for k in [tex]p= \frac{k}{q}[/tex]
[tex]p = \frac{540}{135}[/tex]
[tex]p =4[/tex]

What is the slope and y-intercept of the equation y + 8 = 6x Question 6 options: slope: 6; y-intercept: 8 slope: -6; y-intercept: 8 slope: 6; y-intercept: -8 slope: -6; y-intercept: -8
Answer:
slope: 6; y-intercept: -8
Step-by-step explanation:
The given equation is :
y + 8 = 6x
The general equation of a line is :
y = mx+b...(1)
Where
m is slope and b is y-intercept
Equation (1) can be rewritten as follows :
y = 6x -8
or
y = 6x +(-8) ....(2)
Compare equation (1) and (2) we get :
Slope, m = 6 and y intercept = -8
Hence, the correct option is (c).

A.a reflection about the y-axis followed by a translation
B.a reflection about the x-axis followed by a translation
C.a rotation of 90° clockwise followed by another rotation of 90° clockwise
D.a rotation of 180° followed by a reflection about the line x = 3
Can you also explain please?
Answer:
B. a reflection about the x-axis followed by a translation
Step-by-step explanation:
A reflection over the x-axis, since it is horizontally flipped and has the corresponding coordinates that involve the numbers 1 and 3 (based of the points on (-3,1) and (3,-1).
And it is translated to the right, because it was not rotated at all and is on the right side or 4th quadrant. If it was not translated, the reflection would be below triangle1 with the point on (-3,-1), but the point is instead moved 6 units to the right to be on (3,-1).

Andre and Alina are each saving money. Andre starts with $100 in a savings account and adds five dollars per week Elena starts with $10 in her savings account and add $20 each week after how many weeks for Andre and Elena have the same amount of money in their savings account
Answer:
6 weeks
Step-by-step explanation:
From the question:
Let us represent the number of weeks as x
Andre and Alina are each saving money.
For Andre:
Andre starts with $100 in a savings account and adds five dollars per week
$100 + $5 × x
= 100 + 5x
For Elena
Elena starts with $10 in her savings account and add $20 each week
$10 + $20 ×x
= 10 + 20x
The next step is to equate both algebraic expression for Andre and Elena together
Hence:
100 + 5x = 10 + 20x
Collect like terms
100 - 10 = 20x - 5x
90 = 15x
x = 90/15
x = 6 weeks
Hence, after 6 weeks Andre and Elena would have the same amount of money in their savings account.

6. A rental car agency charges $240 per week plus $0.25 per mile to rent
a car. The charge for a minivan is $180 per week plus $0.40 per mile.
After how many miles is the total charge for each vehicle the same?
Answer:
400 Miles
Step-by-step explanation:
Set up the equations and make them equal to each other and then solve.
240+0.25m=180+0.40m
Answer
400 miles
Step-by-step explanation:
After 400 miles, both will be costing the same, you first create an equation with the values you have, for example, 240 + .25x and you either graph them and find the intersection or guess and check.
Marco has a $15.00 gift card to a movie theater. He wants to buy each of his friends a $3
candy bar. The function f(x)=3x-15 represents the amount of cash needed to purchase x candy
bars after using his gift card. He brings 7 friends. How much of his own money does he need
to spend to buy all 7 friends a candy bar?
Answer:
I believe the answer is 6
Step-by-step explanation:
f(x) = 3x - 15 -- plug 7 into x (that's how many candy bars he's buying)
f(x) = 3(7) - 15 -- solve the equation (just know that 3(7) is the total, and 15 is the amount of money on his gift card.)
f(x) = 21 - 15
f(x) = 6 -- your answer
I hope this helps :)
