Given the system of equations presented here: 3x + 5y = 29 x + 4y = 16 Which of the following actions creates an equivalent syst

em such that, when combined with the other equation, one of the variables is eliminated? (5 points) Select one: a. Multiply the second equation by −1 to get −x − 4y = −16 b. Multiply the second equation by −3 to get −3x − 12y = −48 c. Multiply the first equation by −1 to get −3x − 5y = −29 d. Multiply the first equation by −3 to get −9x − 15y = −87
And pls show work

It would be b. If you combine -3x-5y and 3x+5y, the x's cancel out. That would be the variable.

How does the graph of y=|x|+ 4 compare to the graph of the parent function y=|x|?​
neonofarm [45]

Answer:

Please check the explanation and attached graph.

Step-by-step explanation:

Given the parent function

y = |x|

In order to translate the absolute function y = |x| vertically, we can use the function

g(x) = f(x) + h

when h > 0, the graph of g(x) translated h units up.

Given that the image function

y=|x|+4

It is clear that h = 4. Since 4 > 0, thus the graph y=|x|+4 translated '4' units up.

The graph of both parent and translated function is attache below.

In the graph,

The blue line represents the parent function y=|x|.

The red line represents the image function y=|x| + 4.

It is clear from the graph that the y=|x| + 4  translated '4' units up.

Please check the attached graph.
