A) y=-1/2x+5
B) y=2x+3
C y=-2x+2
D) y=2x+5
Answer: A) y= -1/2x+5
Step-by-step explanation: If the line is perpendicular to the original, the new "m" (coefficient of x) has to be the negative reciprocal of the original "m"

Answer:
x=60
Step-by-step explanation:
If you add all of the interior angles together, it equals 360. Since all the sides are congruent, that means that all of the angles are congruent as well. The equation is 6x=360. Then solve for x
Help! marking branliest answer if gotten right!
Answer: x= 65
Step-by-step explanation:
Vertical angles are equal to each other. So, to solve, write the equation:
2x - 10 = 120
Add 10 to both sides
2x = 130
Divide both sides by 2
x = 65

Answer:
A) m = 16/5
Step-by-step explanation:
We need to find the slope between a choice of two points in this function table. I'll choose points (5,16) and (10,32) however you can choose any point you want.
To find "m" which is the slope, we need to do the following:
m = (y2-y1)/(x2-x1)
m = (32-16)/(10-5)
m = 16/5
The answer is A) m = 16/5
Find the value of b for the triangle using the Pythagorean Theorem.
Step-by-step explanation:
Hey there!
Given;
The given figure is a Right angled triangle, taking reference angle as angle B.
Hypotenuse= AB=5
Base= CB= 4
Perpendicular= AC=b
Using Pythagorean theorem.
[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]
[tex]p = \sqrt{ {h}^{2} - {b}^{2} } [/tex]
Put all values.
[tex]b = \sqrt{ {5}^{2} - {4}^{2} } [/tex]
[tex]b = \sqrt{25 - 16} [/tex]
[tex]b = \sqrt{9} [/tex]
Therefore, the value of b is 3.

My teacher gave me a number and told me to subtract 5 from the number and then multiply the result by 8. Unfortunately, I wasn't listening. I thought she told me to subtract 8 first and then multiply the result by 5. I did those computations correctly and came up with 70 as my answer. What is the correct answer to the question my teacher actually asked me?
Answer:
136
Step-by-step explanation:
If you subtracted 8 and multiplied it later 70 divided by 5 is 14 plus 8 equals 22 so 22 was the number I suppose
22 minus 5 equals 17, 17 times 8 equals 136 so the original answer was 136
The graph below shows the amount of Michael’s paycheck based on a 40 hour work week, plus his commission from sales. Michael earns 50% of the total amount of sales that he makes.
Answer:
Option B.
Step-by-step explanation:
The graph attached shows the amount of Michael's paycheck based on 40 hour wok along with commission from the sales.
There are two variables plotted on the graph.
On x-axis → Amount of sales
On y-axis → Amount of paycheck he received
Point (0, 100) shows the y-intercept.
Since, y-coordinates show the amount of paycheck, y-intercept will show the amount ($100) at zero sales.
Therefore, Option B will be the correct option.

The amount of available disk space on a digital video recorder changed from 81% to 9% after recording 12 episodes of a show. Each episode requires the same amount of disk space. Which statement is true? The change in available disk space is 6% per episode. The change in available disk space is −6% per episode. The change in available disk space is 7.5% per episode. The change in available disk space is −7.5% per episode.
Answer:
The change in available disk space is −6% per episode
Step-by-step explanation:
Given that :
Available disk space changed from 81% to 9% after recording 12 episodes of a show
Each episode requires the same amount of disk space
Change in disk space =
Final % = 9%
Initial percentage = 81%
Change = final value - initial value :
(9 - 81)% = -72%
72% reduction in disk space
Space taken up per episode :
Reduction in space / number of episodes
= -72% / 12
=- 6%

Can someone please help me solve this question? 7-3r=r-4(2+r)
Answer:
There is no solution
Step-by-step explanation:
7−3r=r−4(2+r)
Step 1: Simplify both sides of the equation.
7−3r=r−4(2+r)
7+−3r=r+(−4)(2)+(−4)(r)(Distribute)
7+−3r=r+−8+−4r
−3r+7=(r+−4r)+(−8)(Combine Like Terms)
−3r+7=−3r+−8
−3r+7=−3r−8
Step 2: Add 3r to both sides.
−3r+7+3r=−3r−8+3r
7=−8
Step 3: Subtract 7 from both sides.
7−7=−8−7
0=−15

What is the length of 15,409,000 cubic yard in miles? (to
the nearest hundred)
Answer:
Step-by-step explanation:
The cube root of 15,409,000 = 248.84 yards.
There are 1760 yards in a mile
One edge of a cube = 248.84 / 1760 = .141386 miles.
So a cube would be .00283cubic miles. Your answer does not reach a hundredth place, I don't think.

Just plug in what x is.
h(-4) = 4(-4) + 1
h(-4) = -16 + 1
h(-4) = -15
h(-3) = 4(-3) + 1
h(-3) = -12 + 1
h(-3) = -11
h(1) = 4(1) + 1
h(1) = 4 + 1
h(1) = 5
h(2) = 4(2) + 1
h(2) = 8 + 1
h(2) = 9
h(3) = 4(3) + 1
h(3) = 12 + 1

A line passes through the point (-5,-2) and (0,2) write the equation in point-slope form
Answer:
y=4/5x+2
Step-by-step explanation:
Answer:
y=0.8x+2
Step-by-step explanation:
First, you would figure out the slope using the following equation: (y2-y1)/(x2-x1)=slope.
So, (2--2)/(0--5)= 4/5, or 0.8. This would be the slope.
Then, you would figure out b by putting a data point from the given ones. I chose (0, 2).
2=0.8(0) + b --> 2=0 + b --> 2=b
So, the final equation is y=0.8x+2

A=pir^2 solve for pi
Given problem;
A = [tex]\pi[/tex] r²
Solve for π;
To solve for π implies that we make it the subject of the expression.
So;
A = π r²
Now multiply both sides by [tex]\frac{1}{r^{2} }[/tex]
So;
A x [tex]\frac{1}{r^{2} }[/tex] = [tex]\pi[/tex] x r² x [tex]\frac{1}{r^{2} }[/tex]
r² cancels out from the right side and leaves only π;
π = [tex]\frac{A}{r^{2} }[/tex]
So [tex]\pi = \frac{A}{r^{2} }[/tex]
Refer to the figure at the right. If
m22 = (a + 15)° and m23 = (a + 35)°, find the
value of a such that HĽ I HJ.
Answer:m∠1 = 145°
m∠2 = 35°
m∠3 = 35°
m∠4 = 145°
m∠5 = 145°
m∠6 = 35°
m∠7 = 35°
m∠8 = 145°
Step-by-step explanation:
The required value of a is 20°.
What are complementary angles?In geometry, complementary angles are defined as two angles whose sum is 90 degrees. In other words, two angles that add up to 90 degrees are known as complementary angles.
Now it is given that,
m22 = (a + 15)° and m23 = (a + 35)°
Let m22 and m33 be the angle between HL and HJ.
And since HL is perpendicular to HJ therefore they are complement ot each other.
Thus,
m22 + m23 = 90°
⇒ (a + 15)° + (a + 35)° = 90°
⇒ a° + 15° + a° + 35° = 90°
⇒ 2a° +50° = 90°
⇒ 2a° = 90° - 50°
⇒ 2a° = 40°
⇒ a° = 40°/2
⇒ a° = 20°
Thus, the required value of a is 20°.

A kids' movie ticket costs $5.25.
1. One day, 200 kids' tickets were purchased. What was the total cost of those tickets?
2. Ift is the number of kids' tickets purchased, and c is the total cost of those tickets,
write an equation that relates c tot.
3. Another day, the total cost of kids' tickets was $813.75. How many tickets were
purchased that day?
Answer:
1. $1050
2. $5.25t = c.
3. $813.75 ÷ 5.25 = 155.
Step-by-step explanation:
For the first day, 200 kid tickets were purchased. We know that a singular movie ticket is $5.25. From this information, I know I have to multiply.
200 x 5.25 = 1050.
The answer to number one is $1050.
So t will be the variable that represents the number of kid's tickets and c is the total cost, from this equation, I would create this equation:
$5.25t = c.
I put 5.25 down because that is the cost of a singular child ticket. It would be multiplied by t (total amount of child tickets) and the product would be the total cost of those tickets (c).
The answer to number 2 is $5.25t = c.
Another day, the total cost of the tickets were $813.75. One kid movie ticket is $5.25, so this calls for division.
$813.75 ÷ 5.25 = 155.
The total amount of tickets that were purchased that day was 155 child tickets.
The total amount of tickets that were purchased that day was; 155 child tickets.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that 200 kid tickets were purchased. We know that a singular movie ticket is $5.25.
200 x 5.25 = 1050.
The total cost of those tickets is $1050.
Let t be the variable that represents the number of kid's tickets and c is the total cost, from this equation:
$5.25t = c.
Now multiplied by t (total amount of child tickets) and the product would be the total cost of those tickets (c).
The answer is $5.25t = c.
On another day, the total cost of the tickets was; $813.75. One kid movie ticket is $5.25 thus;
$813.75 ÷ 5.25 = 155.
The total amount of tickets that were purchased that day was; 155 child tickets.
