ANSWER:

<h2><u>y = 3/4x + 10</u></h2>

STEP-BY-STEP:

I will write the equation in the slope-intercept form: y = mx + b

y = y-coordinate

m = slope

x = x-coordinate

b = y-intercept

Part 1: Substitute the knowns into the equation

y = mx + b

4 = (3/4)(-8) + b

1. Simplify

4 = -6 + b

Part 2: Solve for b

1. add 6 to both sides to get b by itself on one side

4 + 6 = b - 6 + 6

2. Simplify

10 = b

Part 3: Re-write equation with 3/4 substituted in for m and 10 substituted in for b

<h2><u>y = 3/4x + 10</u></h2>

Answer:

4=3/4(-8)+b

Step-by-step explanation:

You have to use the equation Y=mx+b

M is your slope so 3/4

x=-8

Y=4

Then u put it into the equation and get 4=3/4(-8)+b

Hope this helps:)

What's the answer to x^2-6x-8?
solong [7]

Answer:

0

Step-by-step explanation:

(x-4)(x-2)=0

If any individual factor on the left side of the equation is equal to 0

the entire expression will be equal to 0

Set the first factor equal to 0 and solve

x=4

The final solution is all the values that make

(x-4)(x-2)=0

x=4,2

One kilogram is 2.2 pounds. If i had 1 pound would that be 0.45 kilograms why or why not?
prisoha [69]

Step-by-step explanation:

1 kg = 2.2 pounds

0.45 kg = 1 pounds to see whether it's correct or not we can cross multiply the given equations

multiply 1 kg with 1 pounds and 0.45 kg with 2.2 pounds then check if they are equal

1 × 1 = 2.2 × 0.45

1 = 0.99 as you can see this is not an equality therefore the statement is wrong.

how much money has to be invested at 5.9% interest compounded continuously to have 15,000 after 12 years?
Scrat [10]
Hi there

The formula is
A=pe^rt
We need to solve for p where
A future value 15000
P present value?
E constant
R interest rate 0.059
T time 12 years
So when you solve for p you get
P=A÷e^rt
P=15,000÷e^(0.059×12)
P=7,389.43

Hope it helps
