Step-by-step explanation:

first step is to find the gradient of the line which "m" on the equation

gradient formula is y2 - y1 ÷ x2 - x1 = -½ as shown on the picture we substituted those points given

2nd step is to substitute on the equation y=mx+c

m= -½

y= 3 (you can choose any from those given points but in my case I chose point A)

x= -2

c= ? only unknown variable so we can can calculate it

substitute as shown on the picture to get c= 2

therefore our equation of the line will be y= -½x+2

<h3>Answer:</h3>

x=30

<h3>Solution:</h3>
  • First, use the distributive property:
  • 8x-3(2x-4)=3(x-6)
  • 8x-6x+12=3x-18
  • Simplify:
  • 2x+12=3x-18
  • 2x-3x=-12-18
  • -x=-30
  • x=30

Hope it helps.

<u>The correct answer is C.  It is the original amount of money the bank loans the borrower.</u>

Step-by-step explanation:

Let's recall that are five basic elements for calculating the payment of a loan:

1. The principal. How much money you borrow.

2. The interest rate. How much money you will pay in addition to the principal.

3. The period of time. How long will it takes you to pay the loan.

4. The frequency of payment. Will you pay every month?, every quarter?, every year or maybe every two weeks?

5. Additional payments. When you have additional income seasonally and you want to lower either the period of time or the interests to pay.

Solve for x: -5/6x= -10/3 x=?
k0ka [10]

Answer:

Solve for x: -5/6x= -10/3 x=?

x = 1/4

Step-by-step explanation:

from the equation ,Solve for x: -5/6x= -10/3 , to solve for x  we will first cross multiply

we have; -15= -60x

divide both sides by -60

-15/-60 = -60x/-60

x = 15/60 ( the minus will cancel out)

x = 1/4

check for your answer  by putting 1/4 where you see x

i.e -5/6(1/4) = -10/3

-5 × 2/3 = -10/3

-10/3 = -10/3......... proved!!
