What is the question?

Step-by-step explanation:

y = x^2 + 4x - 5
I need to know if it is maximum or minimum , the axis of symmetry , the vertex , domain , range ​

Answers

Answer:

i honestly have no idea

Step-by-step explanation:

Answer:

The coefficient of x^2 is positive (here it is 1) so we have a minimum.

Rearrange it to the form (x-a)^2 + b:

(x+2)^2 - 4 - 5 = (x+2)^2-9

This means the minimum, or vertex, is at (-2,-9)

Parabolas are symmetrical horizontally, so the axis of symmetry is the vertical line at the minimum, which is x = -2

The domain is all numbers

The range is y >= -9

The volume of a cuboid is 189cm3.
The length is 7cm and the width is 9cm.
Work out the height of the cuboid.

Answers

The height of the cuboid is 3cm. 7x9x3 = 189
Volume = Length x Width x Height

Volume of cuboid:
Let h cm be the height of the cuboid.

7 x 9 x h = 189

63h = 189

h = 189/63

h = 3


The height of the cuboid is 3 cm.

What is the value of x?
What is the measure of angle A?
What is the measure of angle B?
What is the measure of angle C?

Answers

1. 2x + 20 + x + 10 + 2x - 5 = 180
5x + 25 = 180
5x = 155
x = 31 degrees

2. A = x + 10
A = 31 + 10
A = 41 degrees

3. B = 2x + 20
B = 62 + 20
B = 82 degrees

4. C = 2x - 5
C = 62 - 5
C = 57 degrees

Answer:

∠A =  41

∠B = 82

∠C  = 57

Step-by-step explanation:

Sum of all the angles of triangle = 180

x + 10 + 2x -5 + 2x + 20 = 180

x +2x +2x + 10 - 5 +20 = 180     {Combine like terms}

5x + 25 = 180

         5x = 180 - 25

         5x =155

          x = 155/5

         x = 31

∠A = x + 10 = 31 + 10 = 41

∠B = 2x +20 = 2*31 + 20 = 62 + 20 = 82

∠C = 2x - 5 = 2*31 - 5 = 62 - 5 = 57

Answers

Answer:

h = 8 inches

Step-by-step explanation:

Since these shapes are similar and one side of the bigger shape is double the other side (44 is the double of 22), to find side h, you have to multiply 4 by 2 (It's the same relationship between the two sides of similar shapes). 4 times 2 is equal to 8, which is your answer.

Video Store A charges $8 to rent a video game for one week. Although only members can rent from the store, membership is free. Video Store B charges only $4 to rent a video game for one week. Only members can rent from the store and membership is $84 per year. After how many video game rentals will the total amount spent at each store be the same?
a) Write an equation to model the problem. Let x represent the number of video game rentals.
b) Solve the equation to find to answer the question. (Note: Include the units , which in this case is "rentals"; for example, if you find of a solution of 29, write: 29 rentals.)
​

Answers

Answer:

21 rentals

Step-by-step explanation:

Video Store A = 8x

Video Store B = 84 + 4x

x = number of video game rentals.

After how many video game rentals will the total amount spent at each store be the same?

Video Store A = Video Store B

8x = 84 + 4x

8x - 4x = 84

4x = 84

x = 84/4

x = 21 rentals
