1.1 Pull out like factors :

2x - 6 = 2 • (x - 3)

-3x Simplify ——3 over x2 -9———— x2 - 9

(-3x)/(x^2 - 9) + 4/(2x-6) = (-3x)/[(x-3)(x+3)] + 4/[2(x-3)] = (-3x)/[(x-3)(x+3)] + 2/(x-3) =

100 POINTS! PLEASE HELP WITH MATH

Answers

Step-by-step explanation:

mutiply (-5+i) and 2i with 2i

2i × 2i = 4i^2 ➡-4

2i × (-5+i) = -10i + 2i^2 ➡-10i -2

then do the division

(-10i -2)/-4 = (5i + 1)/2

Multiply the numerator and denominator by the conjugate of 2i to make the denominator a real number:

-5 + 1 / 2i

= -5 + i /2i x i/i

= -5i + i^2 / 2 x i^2

Rewrite i^2 as -1:

-5i + -1 / 2 x -1

Simplify:

= -1 - 5i / -2

Split the fraction into two separate ones:

1/2 + 5i/2

An equation is shown below: 5(2x - 8) + 15 = -15

Write the steps you will use to solve the equation and explain each step.

Answers

5 (2×-8)+15= -15

distribute the 5 into (2×-8) and it becomes

10x-40 + 15 = -15

add -40 and +15

10× - 25 = -15

add +25 to both sides

10x= 10

divide both sides by 10

x = 1

5(2x-8)+15=-15 -15 in both sides 5(2x-8)=-30 /5 2x-8=-6 +8 2x=2 /2 x=1 I hope it helps

Jordan uses a linear equation to model the data in a table. Which reasoning might Jordan have used in the decision to model the data with a linear equation?The products of corresponding x- and y-values are equal.
The ratios of consecutive y-values are equal for evenly spaced x-values.
The change in y-values is not constant, but the change is constant for evenly spaced x-values.
The change in y-values is constant for evenly spaced x-values.

Answers

The change in x values and y values are proportional to each other for the given case. The correct option is (D).

What is the slope of straight line?

The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.

The negative slope indicates the rate of decrease while the positive shows the rate of increase.

In order to form a linear equation from a table,

The slope has to be found first.

For this, the ratio of the difference in the values of x and y are taken.

Which implies that the change in x values are directly proportional to the change in the values of y.

And the proportionality constant is known as the slope.

=> (y₂ - y₁) ∝ (x₂ - x₁)

=> (y₂ - y₁)/(x₂ - x₁) = m

Hence, the change in y values are constant for change in x values.
