Answer:

c) (-2, 1)

Step-by-step explanation:

3x - 3y = -9

2x + y = -3

2x + y = -3

-2x       -2x

y = -2x - 3

3x - 3y = -9

y = -2x - 3

3x - 3(-2x - 3) = -9

3x + 6x + 9 = -9

9x + 9 = -9

    - 9    -9

9x = -18

/9     /9

x = -2

y = -2x - 3

y = -2(-2) -3

y = 4 - 3

y = 1

(x, y) --> (-2,1)

Check your answer:

y = -2x - 3

1 = -2(-2) - 3

1 = 4 - 3

1 = 1

This statement is true

Hope this helps!

Mitch has already spent 26 minutes on the phone, and he expects to spend 2 more minutes with every phone call he routes. Write t
fredd [130]

Answer:

minutes spent on phone (t) is directly proportional to the phone calls routed (p)  with equation t =26+2p.

Step-by-step explanation:

Given:

Number of minutes already spent = 26 minutes

Number of minutes expected to spend on each call = 2

Let number of calls routed be 'p'

Also Let number of minutes on the phone be 't'.

We need to find the relationship between phone calls routed and mins spend on the phone.

Solution:

Now we know that;

Total minutes spent on phone is equal to Number of minutes already spent plus Number of minutes expected to spend on each call routes multiplied by number of calls routed.

framing in equation form we get;

t =26+2p

From above we can see that whenever p increases the value of t will increase too .

Hence we can say that minutes spent on phone (t) is directly proportional to the phone calls routed (p)  with equation t =26+2p.

Check answer. if X=4. What is 3X+6 = 18?
Law Incorporation [45]
Well you have to substitute the 4 in for X. It would make the equation: 3(4)+6=18. (Multiply 3 and 4)
12+6=18 (Add 12 and 6)
18=18

Hope this helped :)
