Answer:

y = -2x - 5

Step-by-step explanation:

Set the slope of the given equation to the reciprocal  to get a perpendicular slope:

y = 1/2x --> -2x

y = -2x + b will be your current equation. To get b, you must insert the given information: (-1, -3)

-3 = -2 (-1) + b

Solve:

-3 = 2 + b

<u>-2   -2      </u>

-5 = b

Thus your equation would be y = -2x - 5.

Jeremy lost his dog, and wants to make some signs to put up in the neighborhood. The cost to make 8 paper signs and 2 laminated
Mashcka [7]

Answer:

cost to make paper signs = $1

cost to make laminated signs = $2

Step-by-step explanation:

Let

x = cost to make paper signs

y = cost to make laminated signs

8x + 2y = 12 (1)

10x + 10y = 30 (2)

Multiply (1) by 5

40x + 10y = 60 (3)

10x + 10y = 30 (2)

Subtract (2) from (3) to solve for x

40x - 10x = 60 - 30

30x = 30

x = 30/30

x = $1

Substitute x = 1 into (1)

8x + 2y = 12

8(1) + 2y = 12

8 + 2y = 12

2y = 12 - 8

2y = 4

y = 4/2

y = $2

cost to make paper signs = $1

cost to make laminated signs = $2
