Answer:

y=-1

Step-by-step explanation:

use point slope formula y-y₁=m(x-x₁)

find m which is slope -1--1/-4--1= 0/-3= 0

plug in the equation and use the first point

y--1=0(x--1)

y=-1

The coordinate pairs (-5, -11), (0, -1), and (5, 9) are solutions to which function?

Talja [164]

So, the slope is 2 for each of the points. Now, you plug it into y=mx+bSo, you get, y=2x+b
To find b, you choose any pair of x and y values.-5=-22+bb=17

There is a bag filled with 6 blue and 5 red marbles.

laiz [17]

Answer:

25/121

Step-by-step explanation:

This is called sampling with replacement.

The probability of getting a red marble in one sample is 5/11. Since you are sampling twice, the probability of picking a red marble both times is 5/11 X 5/11 = 25/121. That is slightly less than ⅕.

How do I solve this question by simplifying?

suter [353]

Answer:

perimeter: 22x-14

area : 24x^2-37x

Step-by-step explanation:

for perimeter, it is the length of all the sides added together

starting at the left and working clockwise

5x+((6x-7)-(3x+1))+2x+(3x+1)+(5x-2x)+(6x-7)

5x+6x-7-3x-1+2x+3x+1+5x-2x+6x-7

combine like terms

perimeter: 22x-14

for area, area of (5x*(6x-7)) and subrtact the missing portion of (2x*(3x+1))

(30x^2-35x)-(6x^2+2x)

area : 24x^2-37x
