What are the values of x and y in the matrix equation below? (pictured) answer options: 1.) x=3 y=+8, -8 2.)x=3 y=+4,-4 3.)x=-3 y=+4,-4 4.) x=-3 y=4

4.) x=-3 and y=4

Step-by-step explanation:

[x+4] + [-9x] = [28]

First plug in x into the equation

[-3+4] + [-9(-3)] = [28]

[1] + [27] = [28]

1+27=28 (True)

Next, plug in y into the equation

[y^2+1] + [-17] = [0]

[(4)(4)+1] + [-17] = [0]

[16+1] + [-17] = [0]

[17] + [-17] =[0]

17 + -17=0 (True)

The Answer is D- X = -3 and Y= 4

Given the matrix equation:

i.e.,

i.e.,

Now, comparing left hand side with right side, we have:

                     and                

i.e.,              and                

i.e.,                    and                

i.e.,        and                

i.e.,                      and                

Hence, third option is correct.

i can you answer this question sweetie!

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
