Answer:

=28

Step-by-step explanation:

3(5 p - 1 p ) - 4 ( 3 p -7) when p = 4

3 (20-4) -4 ( 12 - 7)

60 - 12 -48 +28

= 28

3 ( 5p - p ) - 4 ( 3p - 7 ) =

3 ( 4p ) - 12p + 28 =

12p - 12p + 28 =

0 + 28 = 28

Thus the value of p is not importent at all and the answer is always 28 .

Thru (4,0) parallel to y=1/2x+5

Ne4ueva [31]

Paralell has same slope
y=mx+b
m=slope
y=1/2x+b
find b
(x,y)
(4,0)

x=4
y=0
0=1/2(4)+b
0=2+b
minus 2 both sides
-2=b

the equaiton is
y=1/2x-2
or
x-2y=4

Please solve for x:<br><br> :)

anygoal [31]

Hello!

As you can see, the angles we are given make up a 90 degree angle. We have the equation below.

4x=90

To solve we just divide both sides by 4.

90/4=22.5
x=22.5

I hope this helps!

Solve the system of equations below x-2y=3 <br><br> 2y-3y=9

Crank

First you solve 2y-3y=9.
$2y - 3y = 9 \\ subtract \: 2y \: and \: 3y \\ - y = 9 \\ divide \: by \: - 1 \\ y = - 9$
Now that you have y, then you substitute y into x-2y=3 to find X

$x - 2( - 9) = 3 \\ multiply \: - 9 \times - 2 \\ x + 18 = 3 \\ subtract \: 18 \: on \: both \: sides \\ x = - 15$
Your solution is (-15, -9)
