Answer:
y = - 2x + 110
Step-by-step explanation:
The equation of a line in slope- intercept form is
y + mx + c ( m is the slope and c the y- intercept )
To calculate m use the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 110) and (x₂, y₂ ) = (20, 70) ← 2 points on the line
m = =
= - 2
the line crosses the y- axis at (0, 110) ⇒ c = 110
y = - 2x + 110 ← equation of line
Note: Consider we need to find the factor form of the given expression by taking out the GCF.
Given:
The expression is:
To find:
The factor form of the given expression.
Solution:
We have,
It can be written as:
Taking out the greatest common factor (GCF), we get
Therefore, the factor form of the given expression is .
Answer:
Step-by-step explanation:
(x+1) (x−4) (x+3)
= ((x+1)(x−4)) (x+3)
= ((x+1)(x−4)) (x)+((x+1)(x−4)) (3)
=
