Answer:
Step-by-step explanation:
slope, m = (6-0) /(0--2) = 6/2 = 3
intercept, c at y = -2 when x = 0
Equation
y = mx + c
y = 3x -2
Answer:
Step-by-step explanation:
Based on what you have here as the slope we can set the slope formula equal to 34 using the points (0, 8) and (8, c) to solve for c, then use the points (0, 8) and (a, 5) to solve for a.
c first:
and
and
c - 8 = 272 s0
c = 280
For a:
and
and
-34a = 3 so

That seems a little weird, but when you plug those points into the slope formula to solve for the slope, it works out the way it should.
Bizzare problem. What are the choices?
The triangle angles add to 180.
4x + 7 + 2x +3 + 6x - 10 = 180
12x = 180
x = 15
Dilation doesn't change the angles so we must have
4x + 7 = 5x - 8 and 2x + 3 = 3x - 12 and 6x - 10 = 7x - 25
Fortunately x=15 is the solution to all of these so it's consistent.
Answer:
C
Step-by-step explanation:
Calculate the distance (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 9, 2) and (x₂, y₂ ) = (- 4, 2)
d = 
=
=
= 5 → C
$34807.5 is the answer. 38250 - (38250 x (9/100)) = estimate after the sales tax, that value equates to about $34807.5
