I need help with solving for x please

1. x = 16

2. 2x + 9 = 41

Step-by-step explanation:

So this is the first step.

2x + 9 + 3x + 1 = 90 (collect like terms)

5x + 10 = 90 (subtract 10 on both sides)

5x = 80 (divide by 5 on each side)

x = 16

Plug in to 2x + 9

2(16) + 9 =

32 + 9 =

41 = 2x + 9

Hope this helps! Have a blessed day!

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
