What can you conclude about the hypotenuse of the two triangles?
kogti [31]

Answer: C

Step-by-step explanation:

Since the sides are marked with the little lines, you know they are congruent with each other. Since the sides are congruent, you know the hypotenuse will be congruent.

You can argue that these triangles are similar, but the difference is that similar triangles are the same shape, but not the same size. These triangles are congruent because they are the same size and shape. Therefore, the hypotenuse is congruent.

One positive number is 9 more than twice another. If their product is 95, find the numbers.
mafiozo [28]

Answer:

The numbers are 19 and 5

Step-by-step explanation:

Given

Let the numbers be x\ and\ y.

So:

x = 9 + 2y --- First statement

x*y = 95 --- second statement

Required

Find x and y

Substitute x = 9 + 2y in x*y = 95

(9 + 2y) * y = 95

9y + 2y^2 = 95

Rewrite as:

2y^2 + 9y - 95 = 0

Expand

2y^2 -10y +19y- 95 = 0

Factorize

2y(y -5) +19(y- 5) = 0

(2y  +19)(y- 5) = 0

Solve for y

2y + 19 =0 or y - 5 = 0

2y = -19 or y = 5

y = -\frac{19}{2} or y=5

Since the numbers are positive, we take only:

y=5

Substitute y=5 in x = 9 + 2y

x = 9 + 2 * 5

x = 9 + 10

x = 19

<em>The numbers are 19 and 5</em>

If the graph passes the horizontal-line test, then the function is one-to-one. Functions that are one-to-one have inverses that
seropon [69]

Based on the sample response given, the statements included in the explanation on the horizontal line test are:

  • a reference to the horizontal-line test.
  • a statement that the function is one-to-one.
  • inverse is a function.

<h3>What is the horizontal-line test?</h3>

The horizontal line test is used to not only find out if a graph has an inverse function, but also if that inverse is also a function itself.

To pass the horizontal line test, the function has to be one-to-one which means that a horizontal line can intersect the graphed function at one point in all places. If this happens, then there is an inverse and the inverse itself is a function.
