*Hint: When an equation has | it means the absolute value.

Up in the attachment I have provided above is the way that equation should be graphed.

Because the x is squared, it's known that the graph will have a parabola. The -4 is showing the indent it will have.

 182 Let x = width then y = 6x - 91. P (perimeter) = 2x + 2y = 84 then

2(x) + 2(6x - 91) = 84 | 2x + 12x - 182 =84 | 14x = 84 + 182 | 14x = 266 | x = 19 cm

y = 6x - 91 | y = 6 (19) - 91 | y = 114 - 91 | y = 23 cm

Check: P = 2x + 2y | P = 2(19) + 2(23) | P = 38 + 46 | P = 84 cm (Checked)

Which of the following equations is equivalent to x - y = 5?
Masja [62]

Answer:

6x-6y=30

Step-by-step explanation:

<u><em>The complete options are</em></u>

a) x - 2y = 30

b) 4x - 3y = 30

c) 3x - 4y = 30

d) 6x - 6y = 30

The given equation is

x-y=5

<u>Verify option d</u>

we have

6x-6y=30

Divide by 6 both sides

(6x-6y)/6=30/6

\frac{6x}{6}-\frac{6y}{6}=\frac{30}{6}

x-y=5

therefore

x-y=5  and 6x-6y=30 are equivalent
