Activity B (continued from previous page)
Novay_Z [31]

Answer:

A. (see Step-by-step explanation)

B. (-1, 4)

Step-by-step explanation:

<em>Since both functions are equal to </em><em>y</em><em>, we can set them equal to </em><u><em>each other.</em></u>

-x + 3 = 4x + 8

<em>Add the </em><em>x</em><em> to both sides (because it is negative on the left) and subtract the </em><em>8</em><em> from both sides (because it is positive on the right and we need to isolate the variable).</em>

-5 = 5x

<em>Divide both sides by 5 (because it is being multiplied to the </em><em>x</em><em>) to isolate </em><em>x</em><em>.</em>

x = -1

<em>Next, to solve for </em><em>y</em><em>, we can plug in </em><em>-1</em><em> for </em><em>x</em><em> in either equation from the beginning.</em>

y = -(-1) + 3

y = 1 + 3

y = 4

What is the solution for d+35.5=52?
faust18 [17]

Answer:

d = 16.5

Step-by-step explanation:

Add -35.5 to both sides of the equation, then simplify.

... d + 35.5 - 35.5 = 52 - 35.5

... d + 0 = 16.5

... d = 16.5

In general, if something unwanted is added, adding the opposite will undo that operation.
