Answer:
9.46 = y
Step-by-step explanation:
=================================================================
You have to use the cosine function equation.
cos(38) =
Multiply 12 on both sides.
12cos(38) = y
Solve.
9.46 = y
How to know which one to use:
Sin, Cos, Tan, Sec, Cosec, and Cot
Sin function is to do opposite number side length over the hypotenuse number side
Cos function is to do adjacent (side length that is next to angle) over the hypotenuse
Tan function is to do Opposite over Adjacent,
These are the inverse of each one
Sec is hypotenuse over opposite (inverse of Sin)
Cosec is hypotenuse over adjacent (Inverse of Cos)
Cot is Adjacent over Opposite (Inverse of Tan)

Answer:
Now that the values of m (slope) and b (y-intercept) are known, substitute them into y=mx+b . to find the equation of the line.
y=5/4x+9/4
Step-by-step explanation:
Use y=mx+b to calculate the equation of the line, where m represents the slope and b represents the y-intercept.
To calculate the equation of the line, use the y=mx+b format.
Slope is equal to the change in y over the change in x , or rise over run.
m=(change in y)/(change in x)
The change in x
is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=(y2−y1)/(x2−x1)
Substitute in the values of x and y into the equation to find the slope.
m=1−(6)/−1−(3)
Finding the slope m.
m=5/4
Find the value of b
using the formula for the equation of a line.
b=9/4
Answer:
32
Step-by-step explanation:
v/4 -3=5
+3 so the 3's cancel out
v/4=8
x4 x4
v=32
Answer:
C. 3x - y = -2
Step-by-step explanation:
We know that lines with the same slope are usually parallel
3x - y = -2
-y = -3x - 2
y = 3x + 2
They have the same slope so we can assume that they're parallel
