Answer:
Step-by-step explanation:
hello :
(x + 5) ( x -3 )= x²-3x+5x-15
(x + 5) ( x -3 )= x²+2x-15
Answer:
x² +2x - 15
Step-by-step explanation:
(x + 5) ( x - 3 ) =
= x² + 5x - 3x - 15
= x² +2x - 15
Answer:
Step-by-step explanation:
Given
Point: (-7,2)
x + 3y = -5
Required
Find B- - A in Ax + By = 3
To start with; we need to calculate the slope of x + 3y = -5
Subtract x from both sides
Divide both sides by 3
The slope of the line is the coefficient of x
Slope =
The question says line Ax + By = 3 is parallel to line x + 3y = -5; This means that they have the same slope of
Having calculated the slope, next is to calculate the equation of the line using the following formula;
Where m is the slope; m = ;
Substitute these values in the formula above; the formula becomes
Cross Multiply
Open brackets
Add x to both sides
Add 6 to both sides
Multipby both sides by -3
Comparing the above to Ax + By = 3
