PLEASE HELP!!! Write the equation of a line that goes through the point (6, 3) and is perpendicular to the line y = 4x + 1.
Tpy6a [65]

For this case we have that by definition, the equation of a line in the point-slope form is given by:

y-y_ {0} = m (x-x_ {0})

Where:

m: It is the slope of the line and (x_ {0}, y_ {0})is a point through which the line passes.

We have the following equation of the slope-intersection form:

y = 4x + 1

Where the slope is m = 4

By definition, if two lines are perpendicular then the product of their slopes is -1.

Thus, a perpendicular line will have a slope:

m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {4}\\m_ {2} = - \frac {1} {4}

Thus, the equation will be of the form:

y-y_ {0} = - \frac {1} {4} (x-x_ {0})

Finally we substitute the given point and we have:

y-3 = - \frac {1} {4} (x-6)

Option B

Distribute the expression. <br><br> 5(2<br> s<br> 2<br> −3s+4)
Nookie1986 [14]

If it's just distribution, not solving for s (I mean I could but do you need to?):

5(2s² - 3s + 4)     Distribute/multiply 5 into (2s² - 3s + 4)

(5)2s² - (5)3s + (5)4

10s² - 15s + 20

What is the value of x in the equation <br> -5/8x=-160?
Helen [10]

Answer:

x= 1/256

Step-by-step explanation:

1. multiply both sides by 8x (answer: -5= 8x*-160)

2. divide both sides by -160 (answer: -5/-160 or 1/32 =8x)

3. divide both sides by 8 (answer: 1/256 = x

4. check your answer: -5/(8*1/256)= -160
