Answer:
[1] x - 4y = 22
[2] 2x + 5y = -21
Step-by-step explanation:
Solve equation [1] for the variable x
[1] x = 4y + 22
// Plug this in for variable x in equation [2]
[2] 2•(4y+22) + 5y = -21
[2] 13y = -65
// Solve equation [2] for the variable y
[2] 13y = - 65
[2] y = - 5
// By now we know this much :
x = 4y+22
y = -5
// Use the y value to solve for x
x = 4(-5)+22 = 2
I am sorry if I get it wrong.
Answer:
Given points B ( -1 , 3) and C ( 3, 2)
Step-by-step explanation:
Slope can be calculated by using the formula, we have ,
Slope(m)
= (y2 - y1) / ( x2 - x1)
= ( 3 - 2) / (-1 -3)
= 1/-4
= -1/4

Answer:
2 because it holds the same value as -2 and its the additive inverse
Answer:
1/2
Step-by-step explanation:
if you look at a unit circle, sin(\pi/6) is
so cos of (\pi/6/2) would be \pi/3, and cos of (\pi/3) is 1/2
