Answer:
Step-by-step explanation:
perpendicular is 90 degrees or inverse slope of that point
y = -1/4x -1
so the inverse slope of -1/4 is 4
now the other equation is
y = 4x - 1
So the two equations are
y = -1/4x -1
y = 4x - 1
Answer:
y=2x+10

Answer:
none of the above. (Talk to your teacher about this question.)
Step-by-step explanation:
The differences between length and width are 4, 6, 12, so are not constant at either 4 or 6.
The ratio of width to length is 2/3, 2/3, 3/5, so is not constant at 2/3 or 3/2.
None of the answer choices (even after editing to add appropriate math symbols) describes the relation between length and width.
Answer:
x = 6, 9
Step 1:
To solve this equation, we need to subtract 3 from both sides like this:

Step 2:
We square both sides (multiply using FOIL) to get rid of the radical.

If you did not understand how these were done, here is an example:
(x + 1)(x + 2)
First terms: x * x = <u><em>x^2</em></u>
Outer terms: x * 2 = 2x
Inner terms: 1 * x = x
2x - x = <u><em>x</em></u>
Last terms: 1 * 2 =<em> </em><u><em>2</em></u>
x^2 + x + 2
Step 3:
Solve for x:
9x - 45 = x^2 - 6x + 9
x^2 - 6x + 9 (+45) = 9x - 45 (+45)
x^2 - 6x + 54 (-9x) = 9x (-9x)
x^2 - 15x + 54 = 0
Factor:
(x^2 - 6x) + (- 9x + 54)
x(x - 6) - 9(x - 6)
Factor out (x - 6):
(x - 6)(x - 9) = 0
x - 6 = 0; 6 - 6 = 0
x - 9 = 0; 9 - 9 = 0
Our anwer: x = 6, 9
