Vertical angles are where the top equals the bottom or the left equals the right angle. So we would do:
8x - 13 = 5x + 8
And then substitute.
3x = 21
x = 7
Answer: y=1/2x+4
Step-by-step explanation:
1. y-y1=m(x-x1)
2.y-5=1/2(x-2)
3. solve
4. y-5=1/2x-1
5. add 5 to both sides to isolate the variable
6. this gives you y=1/2x+4
Answer:
Yes
Step-by-step explanation:
2√3 − 2√3 is equal to 0. So what we are trying to find out is if 0 is a rational number. 0 IS a ratinol number as it can be expressed as a fraction of integers.
Answer:
C and D
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, - 6) and (x₂, y₂ ) = (9, 3) ← 2 points on the line
m =
=
= 
Using (a, b ) = (9, 3 ) , then
y - 3 =
(x - 9) → C
Using (a, b ) = (- 3, - 6 ), then
y - (- 6) =
(x - (- 3) ) , that is
y + 6 =
(x + 3) → D
Answer:
The point (0,4) doesn't make either equation true.
Step-by-step explanation:
Consider the equations.
and 
We need to determine the point (0,4) make either equation true.
Substitute x=0 and y=4 in
Which is false.
Substitute x=0 and y=4 in 


Which is false.
Hence, the point (0,4) doesn't make either equation true.
