Answer:

true

Step-by-step explanation:

(-8) + 9 = 9 + (-8)

solve both sides of the equation

-8 + 9 = 1

9 + (-8) is equivalent to 9-8 = 1

so,

1 = 1

this equation is true

hope this helps!! :)

Write an equation of the line that passes through the given point and is perpendicular to the given line.

topjm [15]

Answer:

y = - 3x - 22

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = $\frac{1}{3}$ x + 1 ← is in slope- intercept form

with slope m = $\frac{1}{3}$

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{\frac{1}{3} }$ = - 3 , then

y = - 3x + c ← is the partial equation

To find c substitute (- 6, - 4) into the partial equation

- 4 = 18 + c ⇒ c = - 4 - 18 = - 22

y = - 3x - 22 ← equation of perpendicular line

Question 9 of 25<br> 2 Points<br> What is g(x)?

patriot [66]

Composition means that you can plug g(x) into f (x). This is written as "( f o g)(x)", which is pronounced as "f-compose-g of x". And "( f o g)(x)" means " f (g(x))". That is, you plug something in for x, then you plug that value into g, simplify, and then plug the result into f. hope this helps.

Tina is joining 3 sections of a quilt. Each section has 3 rows of 15 square pieces of fabric. How many squares will be in the co

Tomtit [17]

Answer: There are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.

Step-by-step explanation:

Since we have given that

Number of sections = 3

Number of rows in each sections = 3

Number of square pieces in each row = 15

So, the number of squares that will be in the completed quilt would be

$3\times 3\times 15\\\\=9\times 15\\\\=135$

Hence, there are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.
