2x + 5y = 19

x - 2y = -4

Multiply the second equation by 2

2x - 4y = -8

Now we have:

2x + 5y = 19

2x - 4y = -8

Subtract the second eq from the first to get:

9y = 27

/ 9

y = 3

Now substitute this value into one of the first equations

x - 2(3) = -4

x - 6 = -4

x = 2

Thus, your answer would be option B

Which ordered pair is the y intercept of y=2x^2+3x-3?
rosijanka [135]

Answer:

I think it's A - (0,-3)

Step-by-step explanation:

 x,y

(0,-3)

y-intercept equation for this problem:

y=2x^{2}+3x-3

Break it down to smaller parts:

2(0)^{2} +3(0) = 0

0 - 3 = -3

Rewriting it in a neater way:

=> y = 2(0)^{2} +3(0) -3\\y=-3

Therefore, answer A / the first choice is correct

Can someone help me please
alex41 [277]
I believe the answer is 34.

Explanation:
I used the equation a^2 + b^2 = c^2

10 = a

24 = b

Plug it in.

10^2 + 24^2 = c^2

Get rid of the ^2

10 + 24 = 34
