What is the slope-intercept equation of a line with a slope of -5 and y-intercept of 3?

y = -5x + 3
y = -5x - 3
y = 3x - 5
y = 3x + 5

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

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).

Answer:

42

Step-by-step explanation:

You have to multiply 7 by 4 and 2 then add them together. 7*4 = 28 and 7*2 = 14. 28 + 14 = 42. (Make sure to double-check to see if my answer is correct)

Answer:

42

Step-by-step explanation:

7 x 4=28

7 x 2=14

14+28

=42

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....

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

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

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.

Answer:

The answer is the third option and the last option

Step-by-step explanation:

This is because these are the only two answers you will need to use proportional relationships on. Need to find the y. Did this help? If so, it would be nice to have brainliest.
