Slope intercept form is y=mx+b where m is slow and b is y intercept. since we dont have this info we will have to do some work to solve.

1. find slope. this is change in y du used by change in. so we take the two points given and subtract the y values and divide by difference of x values
m=(8-2)/(-3--1)=6/-2=-3

2
use point slope formula and simplify. this is y-y1=m(x-x1) where (x1,y1) is a point on the l in ne. you can pick either point it doesn't matter. we will use (-1,2)
y-2=-3(x+1)

simplify to slope intercept by solving for y

y-2=-3x-3
y=-3x-1
so we have slope -3 and y intercept -1

For your job, you often fly between Seattle and Miami. The distance between these cities is 2,724 miles. You earn a free flight
Alborosie
So you would multiply 2,724 by two since it is a round trip. Then you would divide 43,000 by that number to get the number.

What is the product of a+3 and -2a2+15a+6b2?
ankoles [38]

Answer: -2a^3 + 9a^2 + 45a + 18b^2 + 6ab^2

Step-by-step explanation:

(a + 3) * (-2a^2 + 15a + 6b^2)

We open the brackets with (a + 3)

a ( -2a^2 + 15a + 6b^2) + 3(-2a^2 + 15a + 6b^2)

Opening the brackets

= a * -2a^2 = -2a^3

a * 15a = 15a^2

a * 6b^2 = 6ab^2

3 * -2a^2 = -6a^2

3 * 15a = 45a

3 * 6b^2 = 18b^2

Let's arrange those values weve gotten together ,don't forget the signs each carry

= -2a^3 + 15a^2 + 6ab^2 - 6a^2 + 45a + 18b^2

Collect the like terms

= -2a^3 + 15a^2 - 6a^2 + 6ab^2 + 45a + 18b^2

= -2a^3 + 9a^2 + 6ab^2 + 45a + 18b^2

Please help Solve 5(2x - 3) = 5x - 10 for c <br><br> A) 2<br><br> B) 1<br><br> C) 0<br><br> D) -1
bixtya [17]

Answer:

B

Step-by-step explanation:

Use distributive property:

5(2x - 3) = 5x - 10

10x - 15 = 5x - 10

Isolate the variable:

10x = 5x - 10 + 15

10x = 5x + 5

10x - 5x = 5

5x = 5

x = 1
