in such cases where 2 line intersect each other, opposite angels are equal
so
2x+2 = 3x - 52
now subtracting 2 from both side
2x +2 -2 = 3x - 52 - 2
2x = 3x - 54
subtracting 3x from both side
2x -3x = 3x -54 - 3x
-x = -54
drividing by -1 both side
-x/-1 = -54/-1
x = 54
Answer: -2
Different in Squares: a^2 −b^2 =(a+b)(a−b)
Rad 7^2-3^2 —> Rad 7^2=7 and -3^2= -9
—> 7-9= -2
Answer:
x = -3 x=8
Step-by-step explanation:
(x+3)(x-8)=0
Using the zero product property
x+3 =0 x -8 = 0
x = -3 x=8
Sent a picture of the solution to the problem (s). Used the hint and substituted all the know quantities.
A linear regression is a regression that can be represented by a linear line of best fit.
The equation of the line of best fit is
<h3>How to determine the equation</h3>
From the graph, we have the following ordered pairs
(x,y) = (50,150) and (100,270)
The slope (m) is then calculated as:
This gives
The regression line crosses the y-axis at b = 33.2
A linear regression is represented as:
y = mx + b
So, we have:
Hence, the equation of the line of best fit is
