Which of the following lines is parallel to x = 7? (2 points) a 3y = 7 b y = 7 c x = y d x = 4

Choice d. is parallel to the line .

Step-by-step explanation:

Refer to the diagram attached. (Created with GeoGebra)

The line is made of all the points on a cartesian plane that meet the requirement . In other words, this line consists of points with x-coordinate . That includes:

That line is perpendicular to the x-axis (the horizontal axis) and intersects the x-axis at the point .

Now, consider the lines in the choices.

The first line requires only that the y-coordinates of its points be 7/3. This line accepts any x-values. Points on this line include:

As a result, this line is parallel to the y-axis and is perpendicular to the line .

Similar to the first, the second line is also parallel to the y-axis and is perpendicular to the line .

The third line requires that the x- and y- coordinates of all its points be equal. Points may include:

This line is slant.

The last line is similar to the given line . This line is also perpendicular to the x-axis. The difference is that this line is three units to the left of the line .

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
