Elanso [62]3 years ago
8 0

Answer:

x = 2

y = -1

Step-by-step explanation:

Since it gives you the value of y already, just plug that into the equation, like so:

y = 4x - 9

x - 3 = 4x - 9

<em><u>Subtract the x from both sides:</u></em>

x - 3 = 4x - 9

-x       - x

__________

-3 = 3x - 9

<em><u>Then, add 9 to both sides:</u></em>

-3 = 3x - 9

+9        + 9

________

6 = 3x

<em><u>Divide both sides by 3:</u></em>

2 = x

<em><u>Now plug in x for y:</u></em>

y = x - 3

y = 2 - 3

y = -1

5. The mall and library are 8 miles apart. On a map, the two buildings are 2 inches apart. How many miles does 1 inch represent
sammy [17]
4 miles represent one inch on the map.

This is because since they are 8 miles apart, and 2 inches in the map, and you want to find out how many miles per inch. You divide 8 by 2 because you want to divide how many miles by how many inches so that you can get 2 parts. That's how you get four.
Now that you cut 8 miles into two parts, you have halves, and half of eight is 4. And 1 inch represents that half since 1 + 1 equals 2 and 4 miles represents each of the two parts since 4+4 equals 8.
