Graph the line giving one point and the slope. 2x-6y=12

koban [17]

Y = mx + c

this is the equation of line and here m is the slope

so, 2x-6y =12 can be changed into standard format

y = 2x/6 - 12/6
y=x/3 +(-2)

so, m = 1/3 , so slope will be 1/3

hope it helped :)

Answer:

7x^(2)-3x+8

Step-by-step explanation:

(5x^(2) - 3x - 2) - (-2x^(2) - +10)

(5x^(2))- (-2x^(2))=7x^(2)

(- 2)-(+10)=+8

A loan for $4000 with interest at 6.75% compounded semi-annually is repaid after 5 years. What is the amount of interest paid?

Artyom0805 [142]

4,000 multiplied by 6.75%=27,000

27,000 multiplied by 5 = 135,000

4,000-135,000=131,000 amount of interest paid

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (-1, -3.75)

Point (-1, 4.5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1--1)^2+(4.5--3.75)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(0)^2+(8.25)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{0+68.0625}$
[√Radical] Add: $\displaystyle d = \sqrt{68.0625}$
[√Radical] Evaluate: $\displaystyle d = 8.25$
