1. -8
2. -3
For 3, is x being multiplied by -5 or added? Because if it’s f(x)=x(2)+x(-5) then it’s 6 but if it’s f(x)= 2x + x-5 then it’s -13

The lines y=-2 and y=-7 are they parallel, perpendicular, or neither?
Vanyuwa [196]

Answer:

parallel

Step-by-step explanation:

An equation of the form

y = k

where k is a number is a horizontal line.

Since both lines have the form y = k, with two different values of k, -2 and -7, these are two different horizontal lines, so they are parallel.

Answer: parallel

Y is inversely proportional to (x+2)² when x=1, y=2
REY [17]

Answer:

y = 18 / (x + 2)²

Step-by-step explanation:

Inversely proportional

y * (x + 2)² = k

when x=1, y=2

k = 2 * (1 + 2)²

k = 18

-----------------------

y * (x + 2)² = 18

Divide both sides by (x + 2)²

y = 18 / (x + 2)²
