The triangles are similar so corresponding sides will be in ratio. The first triangle has sides of 2, 4, and 6. The second triangle has a largest side of 24. You are asked to find the perimeter of the second triangle.
The largest side of the first triangle is 6 and the largest side of the second triangle is 24. This is a ratio of 6:24 which can be reduced to 1:4.
Each side of the second triangle is 4 times as large as the corresponding side of the first triangle.
Now we can calculate the other 2 sides.
2 x 4 = 8
4 x 4 = 16
The three sides are 8, 16 and 24
Perimeter of this triangle is 8 + 16 + 24 = 48

Which point is on the circle described by (x - 2)2 + (y + 3)2 = 4?A. (2, -5)
B. (2, 0)
C. (0, 0)
D. (1, -4)

Answers

Answer: The correct option is (A) (2, -5).

Step-by-step explanation: We are to select the point that is on the circle described by the following equation :

$(x-2)^2+(y+3)^2=4~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

Option (A) :

(x, y) = (2, -5).

We have

$L.H.S.\n\n=(x-2)^2+(y+3)^2\n\n=(2-2)^2+(-5+3)^2\n\n=0+4\n\n=4\n\n=R.H.S.$

So, the point (2, -5) lies on the circle (i). And so, option (A) is correct.

Option (B) :

(x, y) = (2, 0).

We have

$L.H.S.\n\n=(x-2)^2+(y+3)^2\n\n=(2-2)^2+(0+3)^2\n\n=0+9>4=R.H.S.$

So, the point (2, 0) lies outside the circle (i). And so, option (B) is incorrect.

Option (C) :

(x, y) = (0, 0).

We have

$L.H.S.\n\n=(x-2)^2+(y+3)^2\n\n=(0-2)^2+(0+3)^2\n\n=4+9=13>4=R.H.S.$

So, the point (0, 0) lies outside the circle (i). And so, option (C) is incorrect.

Option (D) :

(x, y) = (1, -4).

We have

$L.H.S.\n\n=(x-2)^2+(y+3)^2\n\n=(1-2)^2+(-4+3)^2\n\n=1+1<4=R.H.S.$

So, the point (2, -5) lies inside the circle (i). And so, option (D) is incorrect.

Thus, (A) is the correct option.

the answer is B last time i got this question on a test and i got it right nit sure if its the same test but it is the same question you can try ! sorry for not remembering quite well

Please help I'm desperate...Solve the systems:

a. y=50+3x

y=100-2x

b. x+3y=9

-3x+2y=8

Thanks for helping

(will give brainliest <3)

Answers

the first step that isn’t show here is expressing the system in standard form. I assumed you would already know how to do that so I didn’t include it
As for the second system, I’d be happy to give you a solution for that as well, but I can only post one photo per question so you would have to post it again :)

I recommend you use the app photomath you just have to take a picture of your exercise.

State an equation you could use to find the value of x. Then find the value of x in simplest form.

Answers

You can use the Pythagorean Theorem:

a^2+b^2=c^2
x^2+x^2=(7√2)^2
2x^2=49*2 (combine like terms and square the 7√2)
x^2=49 (divide both sides by 2)
x=7 (square root both sides)

So the equation is 2x^2=98 (simplest form) and x=7

Alan purchased 16 shares of company stock for $390.40. A month later, the total value of his shares fell to $291.20. What is the current price per share if each share costs the same?

Answers

i think that the current price for each share would be $18.20 if the total value went down to $291.20.

So it looks like when Alan initially purchased his company stock, the price per share was $24.40 ($390.40/16).
Being that the stock has fallen, the stock price is now $18.20 ($291.20/16).

Hope this helps.
