Please If you can see if you can help on some of my questions!!!!

PQ // BC 

then

Angle P = Angle B, A is common angle the two triangles are similar

AP/AB  = AQ/AC

8/18 = 12/ AC

AC = 12 * 18/8 = 27 (your ans: D)

AQ + QC = AC

QC = AC - AQ = 27 - 12 = 15 (if it was required) 

tan60 = y/8

y = s tan60 = 8sqrt(3)  (B)

Next time, post each question separately.

Solve each system using substitution: 7x-2y=1 2y=x-1
Mrrafil [7]
Hello :
<span>7x-2y=1 ...(1)
 2y=x-1...(2)
</span><span>substitution  2y in (1) :
</span>7x-(x-1) = 1
7x-x+1 = 1 
7x = 0
x=0
in (2) :   2y = 0-1
2y = -1        y=  -1/2
the <span>system have one solution :  (0 ;-1/2)</span>

- (x + 2)2 + (y - 9)2 = 1
telo118 [61]

Answer:

x+y=-5.75

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

Well, you would simply need to use the distributive property!

-(2)x-(2)2+(2)y-(2)9=1

-2x-4+2y-18=1

Then you need to add/subtract so the similar numbers are together.

-2x+2y-22=1

-2x+2y=23

x+2y=-11.5

x+y=-5.75

(っ◔◡◔)っ ♥ Hope this helped! Have a great day! :) ♥

Please, please give brainliest, it would be greatly appreciated, I only a few more before I advance, thanks!

Can someone please. Heck my answer if it’s wrong please answer it correctly and please show work first pic is the question and 2
PIT_PIT [208]

Answer:

Correct

Step-by-step explanation:

4y = 3x Divide each side by 4

4y ÷ 4 = 1y

3x ÷ 4 = 0.75x

12y = 9x Divide each side by 12

12y ÷ 12 = 1y

9x ÷ 12 = 0.75x

We can see in both equations that 1y = 0.75x

(1y = just y) So the constant of proportionality can be written as y = 0.75x

All of your explanations and descriptions are accurate.
