Answer:
y = (-5/7) x + 1
Explanation:
The slope-intercept form of the line has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept
The given is:
5x + 7y = 7
To put this in slope-intercept form, we will need to isolate the y as follows:
5x + 7y = 7
7y = -5x + 7
y = (-5/7) x + (7/7)
y = (-5/7) x + 1
where:
m is the slope = -5/7
c is the y-intercept = 1
Hope this helps :)
Answer:
6x^3 + 29x^2 + 26x -21
Step-by-step explanation:
(2x^2 + 5x -3)(3x + 7) = 6x^3 + 14x^2 + 15x^2 + 35x - 9x -21
= 6x^3 + 29x^2 + 26x -21
Whenever you multiply or divide an inequality by a negative number, you must flip the inequality sign
