You have to use the y2-y1 over x2-x1.
So, let's plug the numbers in.
(-3,-3)
^ ^
X1 Y1
(4,0)
^ ^
X2 Y2
So, that would be
0-(-3)
——
4-(-3)
The two subtraction signs counteract and become a positive, or addition symbol. So it would be
0+3
——
4+ 3
Do the addition to get 3 over 7 or
3

7
Answer is 9
A(x)=f(b)-f(a)/b-a
where a=-10 b=10
f(x)= x^2+9x+18
f(a)=(-10)^2-90+18=28
f(b)=208
A(x)=208-28/10+10
A(x)=180/20=9
Answer:
Simplifying
6x + -2y = 30
Solving
6x + -2y = 30
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
6x + -2y + 2y = 30 + 2y
Combine like terms: -2y + 2y = 0
6x + 0 = 30 + 2y
6x = 30 + 2y
Divide each side by '6'.
x = 5 + 0.3333333333y
Simplifying
x = 5 + 0.3333333333y
Step-by-step explanation:
Step-by-step explanation:
2x+3=x+x+3
add the X's on the right side together.
2x+3=2x+3
subtract 2x from both sides
3=3
subtract 3 from both sides
0=0
the statement is true for any value of x
