Answer: k = 5/2

Step-by-step explanation:

Hi, to answer this question we have to solve for "k":

2.5(4k+2) =12k

Applying distributive property:

2.5(4k) + 2.5(2) =12k

10k +5 =12k

Combining alike terms:

5 = 12k -10k

5= 2k

Isolating the variable "k"

5/2=k

k = 5/2 or 2.5 (decimal form)

Feel free to ask for more if needed or if you did not understand something.

Which graph shows y= (-5x) -4?
Leya [2.2K]

Answer:

Graph A

Step-by-step explanation

I look at the y-intercept first, and the y-intercept is -4, so looking at each graph you can see both A and D have y-intercepts of -4, since the line intercepts, or goes through the y-axis (the vertical line of the graph) at -4.

Then, you look at the variable that's changing, which is -5x. Since it's a negative, A is the graph that is negatively decreasing, because of its position on the graph. The line is going down, starting in the negative side.
