-1.5(4-n)+2.8

multiply 4-n by -1.5
multiply to both the 4 and -n

-6+1.5n+2.8

add -6+2.8 since they are similar

-3.2+1.5n

1.5n-3.2

I believe this is the simplest form

Find the distance from the point (1, 4) to the line y = 1/3x – 3.
Otrada [13]

Answer: Distance between line and point =

4√5 -3/2√10

Step-by-step explanation:

Distance between the line is

= √ ((9-0)²+(0+1)²)

= √ (89+1)

= √90

= 3√10

Half of the line = 3/2√10

Distance of one side of the line and the point.

= √((9-1)²+(0-4)²)

= √((8)²+(-4)²)

=√64+16

= √80

= 4√5

Distance between line and point =

4√5 -3/2√10

C. 25 D. 6<br> Geometry math question please help me
Sophie [7]

Hello!

According to the dashes, you can see that the two separate triangles are congruent. Therefore, these two angles are congruent. We will solve below.

6n-10=50

We add 10 to both sides.

6n=60

Divide both sides by 6.

n=10

Therefore, our answer is A) 10.

I hope this helps!

2. Perpendicular to y=1/2x -6 that passes through (6,-4) <br> PLEASE HELP ME ASAP
iren [92.7K]

Answer:

To get the slope (which we'll call n) of a line perpendicular to another line with slope (a/b), use

n = \frac{-b}{a}

Then we just plug in the point we want to cross and solve for the constant.

Step-by-step explanation:

we see that m = \frac{1}{2}

so, n = -\frac{2}{1} = -2

now we have the equation

-2x + b = y

plugging in (6, -4) we get

-2(6) + b = -4\\-12+b = 4\\b=4+12=16

This gives us our function

y = -2x + 16

What is the solution to 4x+7=-9?
Nata [24]

Subtract 7 from both sides

4x = -9 - 7

Simplify -9 - 7 to -16

4x = -16

Divide both sides by 4

x = -16/4

Simplify 16/4 to 4

<u>x = -4</u>
