Answers

Answer:

(x + y)² = 121

Step-by-step explanation:

Using the identity

(x + y)² - (x - y)² = 4xy , then

(x + y)² - 5² = 4(24) , that is

(x + y)² - 25 = 96 ( add 25 to both sides )

(x + y)² = 121

Which function represents the transformation that moves figures to the right 3 units and down 7 units?

Answers

Answer:

A

Step-by-step explanation:

Adding positively to an x moves it right, and negative moves left. Adding to a y moves it up, and subtracting moves it down.

The transformation that moves figures to the right 3 units and down 7 units is A. (x, y) ⇒ (x + 3, y - 7)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Translation is the movement of a point up, down, right or left in the coordinate plane. If a point A(x, y) is moved a units right and b units down, the new location would be at A(x + a, y - b).

A function that moves figures to the right 3 units and down 7 units can be represented by:

(x, y) ⇒ (x + 3, y - 7)

Please answer! Will give brainiest! Which of the following side lengths could form a right triangle? Circle all that apply
A. 3, 7, 10 B. 4, 9, 10 C. 5, 12, 13 D. 6, 8, 10

Answers

Answer:

C. 5, 12 and 13

D. 6, 8 and 10

Step-by-step explanation:

To see if three side lengths would give you a right triangle, you have to use the Pythagoras Theorem which is a² + b² = c², where c is the hypotenuse (longest side) and a and b are adjacent to the right angle.

A. 3² + 7² ≠ 10²

9 + 49 ≠ 100

58 ≠ 100

B. 4² + 9² ≠ 10²

16 + 81 ≠ 100

97 ≠ 100

C. 5² + 12² = 13²

25 + 144 = 169

169 = 169

D. 6² + 8² = 10²

36 + 64 = 100

100 = 100

Suppose that gas costs Big Ray $2.00/gallon and that he pays an attendant $100/day. Let C(x)
represent the total daily cost as a function of the price of the gas. Find the formula for C(x)

Answers

Answer:

C(x) = 2x + 100

Step-by-step explanation:

Here, we want to find the formula for C(x)

Here, x will be the number of gallons of gas

so per day, if x gallons of gas were consumed, the daily cost here will be x * 2 = $2x

Adding the cost for the attendant, we have 2x + 100

So the formula for C(x) will be;

C(x) = 2x + 100

An angle measures 38° less than its complement. Find the measures of the two angles.​

Answers

Let c represent the complement.

angle = c - 38
Complement = c

equation :

c - 38 + c = 180
2c - 38 = 180
2c = 218
c = 109

First angle is 71 degrees and the complement is 109.

The measures of the angles are: 64°  and 26°.

Recall: Two angles are complement of each other if they add up to the sum of 90° .

Thus,

Let [tex]x[/tex] represent the first angle

The second angle = [tex](x-38)^{o}[/tex]

Therefore:

[tex]x + (x - 38) = 90[/tex]

Solve for x

[tex]x + x - 38 = 90\\2x - 38 = 90\\2x - 38 + 38 = 90 + 38\\2x = 128\\x = 64[/tex]

The first angle, x, is 64°

The second angle = [tex]x - 38[/tex]

Plug in the value of x

[tex]= 64 - 38\\= 26[/tex]

Therefore, the measures of the two angles are 64°  and 26°

Now move points E and F around to change the orientation of the transversal. Be sure that point F does not cross and that point E does not cross . Do the relationships among the angles that you studied in questions 2 through 4 change when you change the transversal? If so, how?

Answers

Answer:

NO

Step-by-step explanation:

Pairs of alternate interior angles remain congruent, pairs of alternate exterior angles remain congruent, and pairs of same-side interior angles remain supplementary when the transversal is changed.

Pairs of alternate interior angles remain congruent, pairs of alternate exterior angles remain congruent, and pairs of same-side interior angles remain supplementary when the transversal is changed.

What are the interior angles about?

When a transversal intersects two parallel lines, the same-side interior angles formed on the same side of the transversal are supplementary (their measures add up to 180 degrees). If the transversal or lines are altered and are not parallel, the supplementary relationship between same-side interior angles is no longer maintained.

In summary, these angle relationships only hold true specifically for parallel lines intersected by a transversal. If the transversal or the lines change, these angle relationships may no longer remain valid.
