Answer

Explanation

The two lines in the diagram are secants meeting outside the circle.

The products of a secant and the extension of the chord of one line is equal to the products of a secant and the extension of the chord of the other line.

∴ 3(3+5) = 4(4+x)

3 × 8 = (4×4)+(4×x)

24 = 16 + 4x

4x = 24 - 16

4x = 8

x = 8/4

= 2

The area of a rectangular room is 750 square feet. the width of the room is 5 feet less than the length of the room. which equations can be used to solve for y, the length of the room?

Answers

Answer:

Width=25 ft and length=30 ft

Step-by-step explanation:

In order to find the answer let's remember that the area (A) of a rectangle is:

$A=width*length$

Let's assume that the length of the room is 'X' feet.

Becuase the problem mentioned that the width (Y) of the room is 5 feet less than the length, then:

$Y=X-5$

Now, using the area equation we have:

A=width*length

$750=X*Y$ but using the width expression we have:

$750=X*(X-5)$

$0=X^2-5X-750$

Using the root's equation we have:

$X=\frac{-b\±\sqrt{b^(2)-4ac}}{2a}$

$X=\frac{-(-5)\±\sqrt{(-5)^(2)-(4*1*(-750)}}{2*1}$

$X1=30$

$X1=-25$

Because the length (X) can't be negative, then length=30 feet. In order to find the width we have:

$Y=X-5$

$Y=30-5$

$Y=25$

So the width is 25 feet.

In conclusion the room has a width=25 ft and length=30 ft.

Ken drew a pair of intersecting rays and marked the angle between them.Which of these statements best compares the pair of intersecting rays with the angle?
-The rays and the angle have two endpoints each.
-The rays and the angle have their lines extending in opposite directions.
-The rays have a number of points lying on them and the angle has only one point lying on it.
-The rays extend infinitely and the angle is made by the rays which have a common endpoint.
...?

Answers

The best and most correct answer among the choices provided by your question is the fourth choice.

The rays extend infinitely and the angle is made by the rays which have a common endpoint.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:

-The rays extend infinitely and the angle is made by the rays which have a common endpoint.

Step-by-step explanation:

A ray starts from one point and extends in one direction forever.

An angle is the space between two intersecting lines at or close to the point where they meet. In this case two rays intersect each other at one point

Two lines have given equations. At what point do they intersect? 2x-y=1 3x=y-6

Answers

2x-y=1 and 3x=y-6,
y=2x-1 and y=3x+6,
y=2x-1 and 2x-1=3x+6,
y=2x-1 and 3x-2x=-1-6,
x=-7 and y=-14-1
x=-7 and y=-15

check:
for x=-7 and y=-15:
2x-y=1 is -14-(-15)=1 is 1=1 ok
3x=y-6 is -21=-15-6 is -21=-21 ok

answer:
