Step-by-step explanation:
Christopher put 12 gallons of gas in her car. She uses one gallon for every 20 miles he drives.
a. Write an equation to represent the total amount of gas left in his car based upon how many miles she has driven.
b. Find the slope and y-intercept.
Answer:
Equation: y=(-1/20)x+12.
Slope: -1/20
Y-intercept: (0, 12)
Step-by-step explanation:
Let x=the number of gallons of gas in Christopher's car.
If we start with 12 gallons, we have the equation: y=(-1/20)x+12.
This equation is already in slope intercept form, so we see that the slope is -1/20, and the y-intercept is (0, 12).

Find the perimeter and the area of the figure to the nearest hundredth, if necessary.
Answer:
area: 31.63ft perimeter: 21.71ft
Step-by-step explanation:
Divide this up into 2 right triangles and 2 semicircles
Area:
right triangles: 2(0.5(3)(4))= 12ft
semicircles: 2(0.5*π*2.5²)= 19.63ft
area of entire buttcheek: 12+19.63=31.63ft
Perimeter:
top: 6ft
arcs: 2(π*2.5)= 15.71ft
perimeter of entire buttcheek: 6+15.71=21.71ft
Matthew has lived in NY for 10 years. Matthew earns $17.25 per
hour. He worked 5.8 hours on Friday, 4.5 hours on Saturday, and 8
hours on Sunday. How much money did Matthew earn in all on Friday,
Saturday, and Sunday?
Answer:18.3
Step-by-step explanation: 18.3 because 5.8 + 4.5 =10.3 then add 8 its 18.3
Answer:
$315.68
Step-by-step explanation:
We would first add up all of the hours, so that would be 5.8+4.5+8 to get 18.3 hours. Since it is saying $17.25 per hour we would multiply 17.25 and 18.3 to get 315.675. But, because we are dealing with money, our answer would be rounded to the nearest hundredth. So, Mathew earned $315.68 on Friday, Saturday, and Sunday altogether.
Can anyone help please?

(–6,–5)
(–4,–6)
(–2,–7)
(0,–8)
(2,–9)
(4,–10)
(7,–11)
Answer:
Step-by-step explanation:
Ok this is pretty simple. Slope intercept is by far the most simple way to write an equation given that it only has 2 pieces: the slope of the line and the value at which it crosses the y axis (so when x=0). Slope is usually represented by the varriable "m" and the y intercept is usually represented by the letter "b". (Don't ask me why they chose these 2 random letters. It's... it's just whatever... Go with it.) Thus, we have the equation y=mx+b. So anyways.. Slope is just the change in y divided by the change in x. To find this, we just take 2 random points on the graph, subtract the first y from the second y and divide that by the first x subtracted from the second x. Let's use (2,-9) and (4,-10) from this fun little graph you ever so generously provided for us.
I'm bad at transitions so here's the math:
(y2-y1)/(x2-x1)
((-10)-(-9))/(4-2)
-1/2 ------> Thats "m".
SOOO... the slope is -1/2. Cool. BUT WE ARENT DONE
The other thing we need is the y-intercept. You may find yourself asking "what is this... this THING... he speaks of?" Its where the line hits the y axis. Thats is. It's not that hard. In this case it's -8 so b=-8.
Now for the best part... LETS PLUG ALL THOSE DOOHICKEYS IN.
y=mx+b
m=-1/2
b=-8
y=-1/2x+-8-----> y=-1/2x-8
TA DA
MAGIC
If you have any other questions just let me know. You can ask it here or just dm me and I'll respond free of charge. G'Day!

Explain how (-3) - 5 is equal to -8
Answer:
You do -3- 5=-8
Step-by-step explanation:
You do -3- 5=-8
Its just like 3+5=8
But it is in negative so it would be negative 8. But this only works in addition and subtraction. In division and multiplication it is different.
Answer:
It is equal to -8 cuz...
Step-by-step explanation:
(-3) - 5 is -8 how it's cuz a negative number minus a positive number it's gonna be a negative number.
but if a positive number minus a negative number it's gonna be a positive number.
and a negative number minus a negative number it's gonna be a positive number.
Hope this helps....

Step-by-step explanation:
Answer:
<A = 115 degrees, <C = 50 degrees
Step-by-step explanation:
<A+<B+<C = 180 degrees
substitute with the given values: 4x - 13 + 15 + x + 18 = 180 degrees
Solve: x = 32 degrees
Substitute back in for <A : 4(32) - 13 = 115 degrees
Substitute back in for <C: 32 + 18 = 50 degrees
