solve algebraically

1. y = x^2+ 3x - 5
y = x + 3

2. y = x^2- 4x + 6
y = x + 2

3. y = x^2- 10x + 14
y = 7x - 16

4. y = x^2-24
y = x - 12

5. y = x^2- 8x + 28
y = 4x + 8

state the coordinate of the image of the given point B (-10, -6) under a dilation with a center at the orgin with the given scale factor k = 1/2​

Answers

The coordinate of the point B ( -10 , -6 ) after the dilation of -1/2 is given by the coordinate B ' ( -5 , -3 )

What is Dilation?

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

Given data ,

Let the coordinate of the point be represented as B

The value of B = B ( -10 , -6 )

Now , the dilation factor is given by k = 1/2

So , multiply by 1/2 on the x coordinate and y coordinate of the point B , we get

The coordinate of the point B' after the dilation is

B' = B' ( -10/2 , -6/2 )

So , on simplifying the equation , we get

B' = B' ( -5 , -3 )

Hence , the point after dilation is B' ( -5 , -3 )

HELP DUE IN 15 MINS! ΔLMN ~ ΔPQR. Which of the following sets of side lengths could be those of ΔLMN?

A. 2 cm, 3 cm, 4 cm


B. 6 cm, 7 cm, 8 cm


C. 8 cm, 15 cm, 17 cm


D. 9 cm, 12 cm, 15 cm

Answers

Answer: D.

Step-by-step explanation:

If the triangle PQR has sides from biggest to smallest 3,4,5 we need another triangle with a similar ratio to compare it to.

9/3= 3  12/3=4   15/3=5

So the answer is D because I can divide all the sides of the new triangle by the same number to get the sides of triangle PQR

Answer:

D. 9 cm, 12 cm, 15 cm

Step-by-step explanation:

Given

ΔLMN ~ ΔPQR

ΔPQR has sides ratio 3 : 4 : 5

ΔLMN should also have same ratio and the ratio of corresponding sides should be same.

Let's verify the options:

A. 2 : 3: 4

2/3 = 3/4 = 4/5 - this is incorrect

B. 6 : 7 : 8

6/3 = 7/4 = 8/5  - this is incorrect

C. 8 : 15 : 17

8/3 = 15/4 = 17/5  - this is incorrect

D. 9 : 12 : 15

9/3 = 12/4 = 15/5 = 3  - this is correct

Answers

Answer:

G = 50

H = 80

I = 50

Step-by-step explanation:

Angle in a triangle is equal to 180. This means that we will equal all the angles to 180

2x + 2x + 4x-20 = 180

8x - 20 = 180

8x = 180 + 20

8x = 200

x = 200 / 8

x = 25

G = 2 * 25 = 50

I = 2 * 25 = 50

H = 4 * 25 - 20

H = 100 - 20 = 80

One leg of an isosceles right triangle measures 5 inches. Rounded to the nearest tenth, what is the approximate length of the hypotenuse?

A: 2.5 inches
B: 5.0 inches
C: 7.1 inches
D: 9.8 inches

Answers

An isosceles triangle would have two sides the same length so 5^2 + 5^2=50
Sq root of 50=7.07 or 7.1 rounded to nearest tenth so your answer is C: 7.1 inches

Answer:

6955 ft

Step-by-step explanation:

Refer to attached. Point J, segment BJ and angle measures added.

Step 1, find BJ

BJ / AB = sin 20° ⇒ BJ = AB sin 20° ⇒ BJ = 600 sin 20° ≈ 205.2 ft

Step 2, find BP

BJ/BP = cos 75° ⇒ BP = BJ / cos 75° ⇒ BP = 205.2/cos 75° ≈ 792.8 ft

Step 3, find PQ

PQ/BP = sin 35° ⇒ PQ = BP sin 35° ⇒ PQ = 792.8 sin 35° ≈ 454.7 ft

Step 4, find the elevation of peak P
