<span>7x+15=2x+19
Subtract 2x from both sides
5x+15=19
Subtract 15 from both sides
5x=4
Divide 5 on both sides
Final Answer: C.) x= 4/5</span>

Let's solve your equation step-by-step.<span><span><span>    7x</span>+15</span>=<span><span>2x</span>+19</span></span>
Step 1: Subtract 2x from both sides.    <span><span><span><span>7x</span>+15</span>−<span>2x</span></span>=<span><span><span>2x</span>+19</span>−<span>2x</span></span></span><span><span><span> 
                                                                        5x</span>+15</span>=19</span>

Step 2: Subtract 15 from both sides.
<span><span><span><span>    5x</span>+15</span>−15</span>=<span>19−15</span></span><span><span>5x</span>=4</span>
Step 3: Divide both sides by 5.                      <span><span><span>5x</span>/5</span>=<span>4/5</span></span>

It would be the first one because it says that there are 4 times as many red roses as pink roses and so that would be represented r=4p

Hope this helps! Good luck!

Can somebody help me with these 2 questions and show work ?? :)

5. A. (4, -2)

6. C. (x, y) — (x, -y + 5)

Step-by-step explanation:

5. For the formula y = x, the x and y coordinates get swapped.

M = (-2, 4) — M’ = (4, -2)

6. If the coordinates get reflected across the x-axis, the y coordinates become negative.

(x, y) — (x, -y)

Now that the coordinates are reflected, you go 5 units up (+ 5) to get to the reflection of the coordinates if it was 5 units down before it reflected across the x-axis (- 5).

Ex. 1, 6 gets reflected across the x-axis and moved 5 units up. It’s reflection would be equivalent to (1, -1) because it moved 5 units down (1, 1) then reflected across the x-axis (1, -1).

(x, y - 5) reflected across the x-axis is equivalent to (x, -y + 5)
