Answer:

point R

Step-by-step explanation:

reflection rule for the y-axis

p(x, y)->p'(-x, y)

therefore:

M(-5, -6)->R(5, -6)

Type the correct answer in each box. Use numerals instead of words. Consider the equation below. x/h+1=-2 The value of x in term

arlik [135]

Answer:

x = -3h

x = -12

Step-by-step explanation:

Given equation is $\frac{x}{h}+1=-2$

To find the value of x in terms of h we will solve the expression to isolate x on one side of the equation.

by subtracting 1 from both the sides of the equation,

$\frac{x}{h}+1-1=-2-1$

$\frac{x}{h}=-3$

Multiplying 'h' on both the sides of the equation,

$(\frac{x}{h})\times h = (-3)h$

x = -3h

If h = 4,

x = (-3)(4)

x = -12

Which ordered pair would form a proportional relationship with the point graphed below?

kvasek [131]

Answer:

$(x,y) = (-30,10)$

Step-by-step explanation:

Given

$(x,y) = (60,-20)$

Required:

Determine a pair with a proportional relationship

A proportional relationship is:

$k = \frac{y}{x}$

Where k is the constant of proportionality.

$(x,y) = (60,-20)$

So, we have:

$k = \frac{-20}{60}$

$k = -\frac{1}{3}$

This means that for a pair to have a proportional relation, k must be -1/3.

This is true for (c).

Where:

$(x,y) = (-30,10)$

So, we have:

$k = \frac{10}{-30}$

$k = -\frac{1}{3}$
