Write an equation of the line that passes the points (-9,2) and is perpendicular to the line y=3x-12

1 answer:

8 0

If I’m correct use the slope −13 - 1 3 and a given point (−9,2) ( - 9 , 2 ) to substitute for x1 x 1 and y1 y 1 in the point-slope form y−y1=m(x−x1) y - y 1 = m ( x - x 1 ) , which is derived from the slope equation m=y2−y1x2−x1 m = y 2 - y 1 x 2 - x 1 .

Please help, I’ve been stuck on this question for about a hour now.

Hoochie [10]

6x + 5x + (x + 16) + (3x - 1) = 360
11x + x + 16 + 3x - 1
15x + 15 = 360
15x = 345
x = 23

6(23) = 138
((23) + 16) = 39
(3(23) - 1) =68
5(23) = 115

138 + 39 + 68 + 115 = 360

Pre image ABCD was dilated to be image A’B’C’D, where the center of dilation is the origin. What scale factor was used in the di

ArbitrLikvidat [17]

Answer:

The scale factor is 0.25

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

ABCD and A'B'C'D' are similar

therefore

$\frac{A'B'}{AB}=\frac{B'C'}{BC}=\frac{C'D'}{CD}=\frac{A'D'}{AD}$

Find the scale factor

Looking at the graph

we have

$A'B'=1\ unit\\AB=4\ units$

Let

z ---> the scale factor

$z=\frac{A'B'}{AB}$

substitute the values

$z=\frac{1'}{4}=0.25$

Is (1,-4) a solution to the equation y=-2/? A yes В. no

Alex

Answer: B.no

Step-by-step explanation:

To figure this out, plug (1, -4) into the equation y=-2x. 1 is the x value, so we plug it into the x. -4 is the y value, so we plug it into the y spot. In the end we get -4=-2(1). Is this true? No, it isn't. Therefore it is not an answer

How do I solve for Y=x-4 4x+y=26 (X,Y)

blondinia [14]

4x+y=26 replace y with (x-4) & solve for x in this equation.
4x+(x-4)=26
4x+x=26+4
5x=30
x=30/5 

x=6 answer.
y=6-4
y=2 answer.
Proof.
4*6+2=26
24=2=26
26=26 Y=x-4
