What is the equation of a line parallel to y=(3)/(4)x-5 and passes through (12,-2)?

Vika [28.1K]

A parallel line has the same slope as the original line. So in this case the slope of the line is also 3/4. Now how do we know if it intersects the point? We need to adjust the y intercept.

Currently, we know the equation of the line is y= 3/4 x + b, where b is the thing we are looking for. We also have a point, which supplies the x and y. Plug that in and solve for b

-2 = (3/4)*(12) + b

You'll get b= -11

So the equation of the parallel line intersecting the point given is y= 3/4x -11.

I am assuming that the slope is 3/4 based on the way you formatted the original equation, but it's the same steps if the slope is different.

I need help with #4 a-d

lesya [120]

a repeating decimal is placed over 9's instead of 0's. for example: 0.23 = $\frac{23}{100}$ , but 0.232323... = $\frac{23}{99}$

a) x = 0.121212

b) 100(x) = 100(0.121212)

100x = 12.1212

c) 100x = 12.1212

- x = 0.1212

99x = 12

x = $\frac{12}{99}$

d) -2 $\frac{12}{99}$ = -2 $\frac{4}{33}$ when simplified

The number is rational becase it has a repeating decimal

What is the approximate value of sin B?

Jlenok [28]

The acronym for trigs is SOH CAH TOA
Sine means opposite divided by hypotenuse
So, let us find sine.
The opposie side is 16
The hypotenuse is 17.46
$16/17.46$
Use your calculator
The answer is ≈ 0.9164
