The subtracton property of equality allows you to subtract the same amount from both sides of an equation without changing the truth of the equation.
SO YOU HAVE X(-14X+9). ALL YOU DO IS THE DISTRIBUTION PROPERY OR MULIPLE BY X
SO WE GET -14X^2+9X.
X(-14X+9)= -14X(*)X+9(*)X= -14X^2+9X
HOPE THIS HELPS
Answer:
yes
Step-by-step explanation:
Answer:
Step-by-step explanation:
The y-intercept is where x is 0 (0,y)
The x-intercept is where y is 0 (x,0)
Insert 0 as the value for x to find the corresponding y value:
Simplify multiplication:
Isolate the variable. Divide both sides by 4:
Make the variable positive. Multiply both sides by -1:
The y-intercept is at 
.
Insert 0 as the value for y to determine the value of x:
Simplify multiplication:
Isolate x. Divide both sides by 5:
Multiply both sides by -1:
The x-intercept is at 
.

Answer: -3/7
Step-by-step explanation:
The first step is to find the slope of the line
y = mx + c where m is the slope of the line
Rearrange the equation and we get
3y = 7x + 7
y = 7x/3 + 7/3
So the slope of the line 7x - 3y = -7 is 7/3
There is another rule that states: The product of the slopes of two lines perpendicular to each other is -1
So, the slope of the line perpendicular to 7x - 3y = -7 is -1/(7/3) = -3/7
