PLEASE IF YOUR A MATH EXPERT ANSWER THIS I'M LOSING MY SANITY What is the value of 7m−3n when m = 3 and n = 2?
A: 5
B: 15
C: 24
D: 36

B: 15

Step-by-step explanation:

To answer this question, simply plug in the values according to each variable. So, because m = 3, plug the m next to 7 with 3, so then that means that 7 is now multiplied by 3. Then, plug in 2 into n because n = 2, so 3 is being multiplied to n. This is what we get:

7(3) - 3(2)

Now, multiply!

21 - 6

Finally, solve:

21 - 6 = 15

Therefore, the answer is:

B: 15

Hope this helps :)

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
