Answer:
Step-by-step explanation:
y = -4x + 7
perp. 1/4
y - 3 = 1/4(x + 8)
y - 3 = 1/4x + 2
y = 1/4x + 5
The equation of the perpendicular line is y = 1/4x + 5
How to determine the line equation?The equation is given as:
4x + y = 7
Make y the subject
y = -4x + 7
A linear equation is represented as:
y = mx + c
Where m represents the slope.
This means that:
m = -4
A line perpendicular to 4x + y = 7 will have a slope of:
Slope = -1/m
This gives
Slope = 1/4
The equation of the line is then calculated as:
y = Slope(x - x1) + y1
This gives
y = 1/4(x + 8) + 3
Expand
y = 1/4x + 2 + 3
Evaluate
y = 1/4x + 5
Hence, the equation of the perpendicular line is y = 1/4x + 5

Answer:
- True
- True
- False
- True
Step-by-step explanation:
- Subtracting the equation will get rid of y variable therefore it's a correct and logical first step to solve the system
- The solution is indeed (-3, -3) as if we substitute these values in both equation, the equation will be correct and valid.
[tex]-2(-3)+(-3)=3[/tex] (Correct)
[tex]3(-3)+2(-3)=-15[/tex] (Correct)
- We have already determined the logical first step. Multiply by -2 will not get rid of any of the variables. Therefore, this is false.
- The solution can be written as one value since x = y = -3. Therefore, this statement is true.
- 2x – 3y+ | y
-2x-3y+ |y|

Step-by-step explanation:
In a regular polygon each interior angle is 140° greater than each exterior angle. Calculate the number of sides of the polygon
Answer:
18 sides.
Step-by-step explanation:
The interior and exterior angles sum to 180 so:
I + E = 180
also I - E = 140 (given)
So, adding to eliminate E:
2I = 320
I = 160 degrees and the external angle E = 1809 - 160 = 20 degrees.
Since the sum of all exterior angles in a polygon = 360 degrees
- the number of sides = 360 / 20 = 18.
Four people—Rob, Sonja, Jack, and Ang—enter their names into a drawing. The winner receives either a t-shirt or a mug, and which prize they receive is randomly selected.
What is the probability that either Ang wins and is given a mug, or Jack wins (and is given either prize)? Give the answer as a percent.
Answer: 50%
Step-by-step explanation: Good luck! :D
Answer:
The probability is 37.5%
Step-by-step explanation:
There are eight total outcomes, but we only need to focus on three. Ang winning a mug and Jack winning either a t-shirt or a mug, that makes three. Write that as a fraction: 3/8, and then divide. 3 divided by 8 gives us 0.375. But we need a percent so multiply that by 100, that now gives us 37.5.
So, the probability that either Ang wins and is given a mug, or Jack wins is 37.5%. If it makes you feel more confident in this, I put the same exact answer for my assessment and I got it correct.

A.) Write a direct variation equation to represent the cost.
B.) Using the equation found in part a, how much would it cost a hotel to have 150 rooms cleaned
Answer:
Step-by-step explanation:
The cost that a carpet can cleaning company charges is directly proportional to the number of rooms cleaned. The cost to clean 50 rooms is $1,100.
A.) Write a direct variation equation to represent the cost.
Cost ∝ Number of room
C ∝ N
C = kN
k = Constant of Proportionality
k = C/N
k = 1100/50
k = 220
B.) Using the equation found in part a, how much would it cost a hotel to have 150 rooms cleaned
c = 220 × 150
c = $33000
Cost to clean 150 rooms = $33,000

Forrest has determined that if he gets to the bus stop at 7:30 am, there is a 0.15 probability that he misses the bus. If
he arrives at the bus stop three consecutive days at 7:30, what is the approximate probability that he catches the bus all
three days?
Answer: 0.614
Step-by-step explanation:
First find the probability that he catches the bus in a day.
Probability of catching bus once = 1 - Probability of missing bus
= 1 - 0.15
= 0.85
If he arrives on 3 consecutive days at 7:30 am, the probability he will catch the bus is:
= (P | Day 1) * (P | Day 2) * (P | Day 3)
= 0.85 * 0.85 * 0.85
= 0.614
The approximate probability that he catches the bus all three days is 0.614.
Given that,
Forrest has determined that if he gets to the bus stop at 7:30 am, there is a 0.15 probability that he misses the bus.
If he arrives at the bus stop three consecutive days at 7:30,
We have to determine,
What is the approximate probability that he catches the bus all three days.
According to the question,
The probability that he catches the bus in a day.
Probability of catching bus once = 1 - Probability of missing bus,
= 1 - 0.15
= 0.85
If he arrives on 3 consecutive days at 7:30 am,
Then, the probability he will catch the bus is:
= (P | Day 1) × (P | Day 2) × (P | Day 3)
= 0.85 × 0.85 × 0.85
= 0.614
Hence, The approximate probability that he catches the bus all three days is 0.614.

that corner is same as the one across it sorry I don’t know how to explain it very well but it’s Angel is linear to the one across it mean it’s the same
Answer:
C. 130 degrees
Step-by-step explanation:
The total degrees of the interior angels of a six sided ploygon is 720, so all you need to do is add the shown angles together and subtract that number from 720:
130 + 130 + 130+ 100 + 100 = 590
720 - 590 = 130

Answer:
x = 12
Step-by-step explanation:
Segment lengths of each chord have the same product.
(x -2)(x +6) = 9×20
x² +4x -12 = 180
x² +4x +4 = 196 . . . . . add 16 (complete the square)

Answer:
y=2x+5
Step-by-step explanation:
I used 2 as the slope bc we were given an equation above: y=2x-4. Since parallel lines have same slopes and different y-intercepts, hence, I easily got 2 as the slope.
