Answer:
Step-by-step explanation:
Using first equation in the second gives you
x-3(-2x+1)=11
x+6x-3=11
7x-3=11
7x=14
x=2, making y=-2x+1 become
y=-2(2)+1
y=-4+1
y=-3 so the solution is the point
(2,-3)
Answer:
sin(α) -cos(α)
Step-by-step explanation:

-8y = -2x + 16
y = 1/4x - 2
y = 1/4x + 3
Answer:
3/8
Step-by-step explanation:
There are 24 cards in a euchre deck with 4 Jack and 6 spade
P (J U S) = 4/24 + 6/24 - 1/24 = 1/6 + 1/4 - 1/24 = 3/8
