3(-2x + 6) - x + 3 = 0
-6x + 18 - x + 3 = 0
-7x + 18 + 3 = 0
-7x +21 = 0
-7x = -21
-7x/-7 = -21/-7
x = 3
y = -2(3) + 6 
y = -6 + 6
y = 0
x= 3 y = 0

Recall from Intermediate Algebra that two non-vertical lines are perpendicular if and only if they have negative reciprocal slop

Complete Question

The complete question is shown on the first uploaded image

Answer:

The line is y  =  -4 x

Step-by-step explanation:

From the question we are told that

The line is y  =  \frac{1}{4} x  + 8

The point is P(0,0 )

Generally the equation for a line is yn =  mx  + c

Now comparing this with the given equation we see that

m  =\frac{1}{4} =  slope

C  =8  =  intercept

Generally the slope of the perpendicular to the given line is mathematically evaluated as

m_1  = -  \frac{1}{m}

=> m_1  = -  \frac{1}{ \frac{1}{4}}

=> m_1  = -4

Generally from the univesal equation of a line and the given point we have that

y = mx + c at p(0,0) and m_1 =  -4 is

0 = -4 (0 ) + c

=> c = 0

Hence the equation perpendicular to the line given at the point given is

y  =  -4 x

What is an equation of the line that is parallel to y=4x−10 and passes through (1, 13) ?
klasskru [66]
If a line is parallel to another line,Then the gradients are the same.So m=4 .Using general formula for str8 line, y=mx+c
y = 4x + c
sub in coorfinates (1,13)
13  = 4 + c
So C=9.
y = 4x + 9

I NEED HELP WITH NUMBER 4​
weeeeeb [17]

Answer:

4.5 inches

Step-by-step explanation:

To find the height in inches of the model, you need to change the ration into a fraction:

\frac{1}{50}

Then try to figure out the value of the denominator in terms of the ratio:

\frac{1}{50} =\frac{x}{725}

In this equation we need to figure out how much the denominator of the fraction is changing by, by dividing 725 by 50. Then, multiply that by one:

4.5
