PLEASE HELP WITH THESE y- (-8) = (-5)

x + 21 = (-2)

x + 21 = (-2)

(-10) + r = (-2)

(-6) + b = 9

Step-by-step explanation:

1. y = -3

2. x= -23

3. r = 8

4. b= 15

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
