Answer:

(x+5)^2=81 would be correct

Step-by-step explanation:

solution (if you want it)

x² + 10x + 25 = 81

x² + 10x - 56 = 0

(x + 14)(x - 4) = 0

x = 4, x = -14

A line passes through the points (0, 14) and (18, 15) . What is its equation in slope-intercept form?
MAXImum [283]

Answer:

y= 1/18x + 14

Step-by-step explanation:

Well we can first right the equation like  :  to find the slope

14- 15

____  = -1/-18 = 1/18

0-18

Now we know  the slope is 1/18

we can substitute one point in the equation and the slope to find the equation

let's take 0,14

14= 1/18 ( 0 ) + b

14=b

so b= 14

the y-intercept is 14

the equation is

y= 1/18x + 14

Solve the equation <br> 4b + 22 = 5(b + 4) − 1
Mamont248 [21]
ANSWER:
4b + 22 = 5b+ 20-1
4b + 22= 5b +19
subtract 22 OR 19 from each sidE IM GOING TO DO 22.
4b + 22-22= 5b + 19 -22
4b = 5b - 3
subtract 5b from each side.
4b -5b = 5b-3-5b
-1b = -3
a variable cannot be negative so multiply each side by a negative 1. two negatives make a positive.
(-1) -1b = -3(-1)
b=3
