I am not really sure about |8|
I'll get back to you if I can find the answer
Answer:
x = 3.5
y = - 4
Step-by-step explanation:
2(4x + 7y = -14)
8x + 14y = -28
8x + 5y = 8
- (8x + 14y = -28)
--------------------------
- 9y = 36
y = 36/-9
y = - 4
4x + 7y = - 14
4x + 7(- 4) = - 14
4x -28 = - 14
4x = 14
x = 14/4
x = 3.5
Answer:
in slope-intercept form y = 5/4x in y-intercept form is b = 0. try to use math___way dot com
Step-by-step explanation:
3² + 7 - y² - 5 - 2y² -1
= -3y² + 9 + 1 = -3y² + 10
