Use substitution to answer the system <br> 2x-3y=17<br> x=2y+10<br><br> x=<br><br> y=
bearhunter [10]
First, you substitute each x in the first equation-  2(2y+10)-3y=17
Next, simplify -    4y+20-3y=17
y+20=17
y=-3

Next, substitute the y in for the second equation, x=2y+10
x=2(-3)+10
x=-6+10
x=4
ANswer:
x=4
y=-3
Hope this helps!

Please help on this one!
tiny-mole [99]

We can usually get a couple of facts for these that let us rule out answers without working out all the details.

The green and red areas are below a CUP parabola, opening up.  CUP stands for concave up positive, and tells us there's a positive coefficient on x².  Unfortunately all the choices have a positive 1 coefficient, no help here.

Since the areas are below they're going to be y ≤ x² + other stuff.  That rules out B and C.  

The red and blue parts are below the line, and the line has a positive slope.  So that's y ≤ mx + b where m>0 is the positive slope.  That rules out D with the negative slope.


Answer: A

Please help, I am terrible at math
Zarrin [17]

Answer:

the correct option is D (12 units, 14 units, 10 units)

Step-by-step explanation:

P= 36

2t + 2 + 2t + 4 +2t = 36

combine like terms

6t + 6 = 36

subtract 6 from both sides

6t = 30

30/6 = 5

T = 5 so plug the t in the other equations

2(5) + 2 = 10 + 2 = 12

2(5) + 4 = 10 + 4 = 14

2(5) = 10

To check combine all the numbers above and you would get 36
