Answer:
<h2>x = 2</h2>
Step-by-step explanation:
3 - x + 1 = 2 <em>combine like terms</em>
-x + (3 + 1) = 2
-x + 4 = 2 <em>subtract 4 from both sides</em>
-x +4 - 4 = 2 - 4
-x = -2 <em>change the signs</em>
x = 2
They’re both perpendicular, I used a graphing calculator to get the interpret answer
Answer:
The coefficient of correlation=0.5
Step-by-step explanation:
We are given that
Covariance between the variable x and y=18
Variance of x=16
Variance of y=81
We have to find the coefficient of correlation
We know that
Coefficient of correlation
Using the formula
Hence, the coefficient of correlation=0.5
Answer: y=4x-5
Step-by-step explanation:
The slope of y=4x+23 is:4 m=4
The parallel line needs to have the same slope of 4
Solve it using the "point-slope" equation of a line: y− y1 = 2(x − x1)
substitute or put in the point (2,3):
y − (3) = 4(x − 2)
y - 3 = 4x - 8
put it in slope intercept form y = mx + b
y = 4x − 5
