Answer:
Perpendicular
Step-by-step explanation:
Parallel lines have equal slopes.
The product of perpendicular slopes = - 1
Calculate the slopes of u and v using the slope formula
m =
with (x₁, y₁ ) = (- 51, 65) and (x₂, y₂ ) = (- 46, 96)
m = =
Repeat with (x₁, y₁ ) = (- 37, 85) and (x₂, y₂ ) = (- 6, 80)
m = = -
Since × - = - 1
Then the lines are Perpendicular
Answer:
14 weeks
Step-by-step explanation:
Let's create and equation to display this situation. Toby already has $70 saved, so that is not the variable and no x should go next to it. He is saving $15 more each week. Lastly, we want to end up with $280 saved. The equation will look like this, given the information:
15x + 70 = 280
To find how many weeks it will take, solve the equation!
15x = 210 Subtract 70 from 280
x = 14 Divide 210 by 15
Therefore, it will take Toby 14 weeks to save up for a new skateboard.

A = (1/2). AC. BD
3x² + 6x = (1/2). (x + 2). BD
6x² + 12x = (x + 2). BD
6x(x + 2) = (x + 2). BD
6x = BD
