Hello from MrBillDoesMath!
Answer:
sqrt(15)/4
Discussion:
The attachment shows a right triangle where arcsin(@) = 1/4. (The arcsin means find the angle whose sine is 1/4 as is done in the triangle.) The missing side, sqrt(15), shown in red, was determined by the Pythagorean theorem.
Then cos(@) = cos(arcsin(1/4)) = sqrt(15)/4
Thank you,
MrB
Answer:
y = -4x + 11
Step-by-step explanation:
Slope m= -4
Point (2,3)
![y- y_{1}=m(x-x{1})\\](https://tex.z-dn.net/?f=y-%20y_%7B1%7D%3Dm%28x-x%7B1%7D%29%5C%5C)
y - 3 = -4(x - 2)
y - 3 = -4x - 2 * -4
y - 3 = -4x + 8 {add 3 to both sides}
y -3 + 3 = -4x + 8 + 3
y = -4x + 11
Answer:
[See Below]
Step-by-step explanation:
✦ Divide by -2 on each side:
✧ -2 / -2 = Cancels Out
✧ -6 / -2 = 3
So x would be 3, -3.
- |x| Just means absolute value. Which in short just means if it's negative it becomes positive.

Answer:
Step-by-step explanation:
let
x-y =-1
x+y=l
2X=0
x=0 and
0-y=-1
y=1 therefore the correct answer
x=0&y=1
