How can you describe the graph of the equation y= mx + b? Explain
Answer:
mx is the slope. b is the y-intercept
Step-by-step explanation:
the first thing you should always do is identify your slope this is key for graphing. remember your slope is b so what ever b is you locate that point in the x axis.
then whatever your slope is remember that it is rise over run so say your equation is y=3x+5 you plot the point on the y intercept which is 5. now 3x is your slope so you put it as a fraction to make it easier this is what it looks like in a fraction "3/1" so you go up 3 on the graph and over 1 because of rise/run
Please help!! I'm super confused

HELP ASAP 3.) Andy's Karpet Kleaning charges a $23 consultation fee, plus $17 per hour to clean carpets. Stanley
Steemer charges a $37 consultation fee, plus $13 per hour. After how many hours will the total charge be the
same? What is the charge?
Answer:
After 3.5 hours and the charge is $82.50.
Step-by-step explanation:
Setting up the equations equal to each other will give a solution (x-value) that makes both sides equal (the same price) after the same amount of hours (x-value).
13x + 37 = 17x +23
x = 3.5
Then plug the hours into either side to get the equal price.
13(3.5) + 37 = $82.50
OR
17(3.5) + 23 = $82.50

Answer:
arc AB = 90 degrees
x = 9
arc AD = 108 degrees
arc DC = 139 degrees
arc BC = 13 degrees
arc ADC = 247 degrees
Step-by-step explanation:
12x+(17x-14)+(2x+5)+90 = 360
31x+81 = 360
31x = 279
x = 9
arc AD = 12(9) = 108 degrees
arc DC = 17(9)-14 = 139 degrees
arc BC = 2(9)+5 = 23 degrees
arc ADC = 108+139 = 247 degrees

Tom and Jerry decide they want to see if they can throw a ball back and forth to each other from their 3rd story bedroom window. Tom throws the ball upward from the window which is 25 feet above the ground. He is able to throw the ball upward at a speed of 70 miles per hour! Which equation represents the height of the ball during the time after it is thrown upward?
Note: There are 5,280 feet in a mile. Measurements are rounded to the nearest thousandths place.
A. h= -16t^2 + 70t + 25
B. h= -16t^2 + 25t + 70
C. h= -16t^2 + 102.67t + 25

The value of a car decreases by 5% each year. Sophie bought a car two years ago for £10000. Work out the value now.
Given:
The value of car before two years = £10000
The value of the car decreases by 5% each year.
To find:
The present value of the car.
Solution:
The exponential decay model for present value is
[tex]y=a\left(1-\dfrac{r}{100}\right)^t[/tex]
Where, a is the initial value, r is the rate of decay and t is time in years.
Putting P=10000, r=5 and t 2, we get
[tex]y=10000\left(1-\dfrac{5}{100}\right)^2[/tex]
[tex]y=10000\left(1-0.05\right)^2[/tex]
[tex]y=10000\left(0.95\right)^2[/tex]
On further simplification, we get
[tex]y=10000(0.95)(0.95)[/tex]
[tex]y=9025[/tex]
Therefore, the present value of the car is £9025.

They are 20 blocks per mile in tara's city. Tara's walks 13 blocks. Her fitness tracker say he walk 0.71 mile. Show if her fitness tracker is accurate.
Answer:
Step-by-step explanation:
13 blocks × (1 mile)/(20 blocks) = 13/20 mile = 0.65 mile
Tracker is inaccurate
The fitness tracker is inaccurate.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, there are 20 blocks per mile.
20 blocks = 1 mile
1 block = (1/20) mile
13 block = (13/20) mile
13 block = 0.65 mile
Therefore, Tara walks 0.65 miles, not 0.71 miles.
Hence, the fitness tracker is inaccurate.

The measure of angle D is 50⁰, the measure of angle E is 80⁰, and the measure of angle F is 10x . What is the value of x ?
By the interior angle theorem of triangles, the value of x is 5°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know the sum of the interior angles in a triangle is 180°.
Given, In a triangle DEF the measure of angle D is 50⁰, the measure of angle E is 80⁰, and the measure of angle F is 10x .
Therefore, m∠D + m∠E + m∠F = 180°.
50° + 80° + 10x = 180°.
10x = 180° - 130°.
10x = 50°.
x = 5°.

The captains of the soccer team describe ordering identical T-shirts for the team. Bindi says the total cost is $192. Gina says the cost is 8t, where t is the number of T-Shirts. Which person tells how much each T-shirt costs? How do you know?
Answer:
Both of them.
Step-by-step explanation:
Gina says the cost is 8t, which means you can easily find out the cost of each t-shirt if you know the the total cost too. Bindi says the total cost was 192, which is completely useless on its own, but paired with Gina's info, you can get the answer. Divide 192 by 8, and you get the cost of each t-shirt.

lines a and b are parallel. if the slope of line a is 1/4 what is the slope of line b?
Answer:
1/4
Step-by-step explanation:
we know that the lines A and B are parallel.
The term "parallel" implies that they will never meet each other, and to do so, the lines must have the same slope.
So the slope of line A is the same as line B (as for all parallel lines have the same slope)
So the slope of line B is also 1/4

A phone company offers two monthly plans. Plan A costs $8 plus an additional $0.09 for each minute of calls. plan B cost $16 plus an additional $0.07 for each minute of calls.
a. For what amount of calling do the two plans cost the same? minutes
b. What is the cost when the two plans cost the same? $
Answer: 72
Plan A = 30 +0.15x
Plan B = 16 +0.20x
30+0.15x = 16+0.20x
subtract 16 from each side
14 +0.15x = 0.20x
subtract 0.15x from each side
14=0.05x
x = 14/0.05 = 280 minutes
280*0.15 = 42 +30 = $72
280 * 0.20 = 56 +16 = 72
280 minutes and cost $72 each

_________________________ 6Harry is planning a holiday for 4 people for 7 days. Here are the costs for the holiday for each person. Travel£150 Hotel£50 for each day Spending money£250 Work out the total cost of the holiday for 4 people for 7 days.
Answer: $3,000
Step-by-step explanation:
The cost for a single person is:
Travel £150
Hotel £50 for each day
Spending money £250
Hotel is the only one that changes per the number of days so the total cost for a single person for 7 days is:
= 150 + (50 * 7) + 250
= 150 + 350 + 250
= $750
There are 4 people so the total cost will be:
= 750 * 4 people
= $3,000
