Answer:

1)y=2x-1: Neither

2)y=-2+5: Parallel

3)y=12x+7: Perpendicular

Step-by-step explanation:

I went on Desmos.com and graphed all of the equations. 1) crosses the equation but is not perpendicular because it doesnt form a 90 degree angle. 2) is obvious when you look at the graph and lastly 3) is the only one left and when it crosses it makes a 90 degree angle. Hope this helps <3

Y = -2x + 5 is parallel to line as the slopes ( = -2) are the same.

the other 2 lines are nether parallel or perpendicular

Solve each equation. 1/3a = -5 a = ? 12 - b = 12.5 b = ? -0.1 = -10c c = ?

Rina8888 [55]

Answer:

a = -15, b = -.5, c = -1

Step-by-step explanation:

1/3a = -5 --> multiply each side with 3 --> a = -15

12 - b = 12.5 --> subtract 12 from both sides --> -b = .5 --> multiply each side with -1 to get b positive --> b = -.5

.1 = -10c --> multiply each side with -10 --> c = -1

In triangle XYZ, angle Y = 45º and angle Z = 60º. If XZ = 4, then what is XY?

Katena32 [7]

Answer:

$XY = 4.9$

Step-by-step explanation:

Given

$XZ= 4$

$\angle Y = 45$

$\angle Z = 60$

Required

Determine the measure of side XY

To do this, we make use of sine law. This is as follows:

$\frac{a}{\sin\ A} = \frac{b}{\sin\ B} = \frac{c}{\sin\ C}$

In this case:

$\frac{4}{\sin(45)} = \frac{XY}{\sin(60)}$

Cross Multiply

$XY * \sin(45) = 4 * \sin(60)$

$XY * 0.7071 = 4 * 0.8660$

Make XY the subject

$XY = \frac{4 * 0.8660}{0.7071}$

$XY = \frac{3.4640}{0.7071}$

$XY = 4.89888276057$

$XY = 4.9$ -- approximated

What is the next value 4d 7g 10j 13

bearhunter [10]

13m 16p

Add three to every number next as well as move up three letters.

For example:
1A is the starting point.
To get from 1A to 4D you add three.

1 + 3 = 4
A to get to D is three letters up.
A b c D

Same thing for 4D to get to 7G.

4 +3 = 7
D to get to G
D e f G

Your answer:
I'm not sure if you wanted me to find the letter of the equation or the actual next part. On your question you have just 13 up there, no letter so if youre trying to find the letter (13m) is your answer.

If you're trying to find the next equation to the puzzle (16p) is your answer.

Hope this helped!:)
