Step-by-step explanation:
Option B is correct.
I'm sure (-3 , 4)
Answer:
x=-3, y=4. (-3, 4). B)
7x+2y=-13
-3x-8y=-23
-------------------
4(7x+2y)=4(-13)
---------------------
28x+8y=-52
25x=-75
x=-75/25
x=-3
7(-3)+2y=-13
-21+2y=-13
2y=-13-(-21)
2y=-13+21
2y=8
y=8/2
y=4
3x+5=17
x=4
There you go :)
x = 4
y = 3
x = 10 - 2 y
substitute x = 10 - 2y into 2x - y = 5
20- 5y = 5
then
and
Mark brainliest
A. 5
because 13 is the hypotenuse and 8 is the sine
