Answer:

a. -21

b. -16

c. -11

d. -9

Step-by-step explanation:

if x is less than -2, then u have to use the equation 5(x)-1

if x is greater than or equal to -2, then you have to use the equation (x)-9

Answer:

Step-by-step explanation:

This is a ‘piece wise function’ meaning it has different functions depending on the value of the independent variable, x.

So for questions a and b where x<-2 you sub the x value into the top equation, 5x-1.

f(-4)=5(-4)-1=-20-1=-21

f(-3)=5(-3)-1=-15-1=-16

Since the second two x values are not less than -2, you sub the x values into the second equation x-9

f(-2)=-2-9=-11

f(0)=-0-9=-9

Right triangle XYZ is shown. Y (2,6) (1, 2) 6 х 7 Z Rounded to the nearest hundredth of a unit, what is the length of the hypotenuse?

PLEASE HELP ASK

Answers

Answer:

8.12

Step-by-step explanation:

We obtain the distance between x and y

d = sqrt[(x2 - x1)² + (y2 - y1)²]

d = sqrt[(1 - 2)² + (2 - 6)²]

d = sqrt[1 + 16)

d = sqrt(17)

d² = 17

From Pythagoras rule;

Hypotenus = sqrt(Adjacent² + opposite²)

Hence,

Hypotenus = sqrt(17 + 7²)

Hypotenus = sqrt(17+ 49)

Hypotenus = sqrt(66)

Hypotenus = 8.124

Hypotenus = 8.12

A pound of popcorn is popped for a class party. The popped corn is put into small popcorn boxes that each holds 120 popped kernels. There are 1,600 kernels in a pound of unpopped popcorn. If all the boxes are filled except for the last box, how many boxes are needed, and how many popped kernels are in the last partially filled box?

Answers

Answer:

14 ; 40

Step-by-step explanation:

Number of unpopped popcorn = 1600 kernels

Kernel per popped corn = 120

Number of boxes needed :

Number of unpopped / kernel per popped corn

1600 / 120

= 13.3333

Hence, number of boxes needed = 14

Number of popped kernel. In partially filled box :

1600 - (120 * 13)

1600 - 1560

= 40

2y+3=5x-18. make x the subject

Answers

[tex]x = \frac{2y + 21}{5} [/tex]

Step-by-step explanation:

1) Add 18 to both sides.

[tex]2y + 3 + 18 = 5x[/tex]

2) Simplify 2y + 3 + 18 to 2y + 21.

[tex]2y + 21 = 5x[/tex]

3) Divide both sides by 5.

[tex] \frac{2y + 21}{5} [/tex]

4) Switch sides.

[tex]x = \frac{2y + 21}{5} [/tex]

Hope it helps.

sorry if its wrong.

The equation 2y + 3 = 5x - 18 can be rearranged to make x the subject as x = (2y + 21) / 5.To make x the subject of the equation 2y + 3 = 5x - 18, we need to isolate x on one side of the equation.

Let's rearrange the equation step by step:

2y + 3 = 5x - 18

First, let's move the constant term (-18) to the other side by adding 18 to both sides:

2y + 3 + 18 = 5x

2y + 21 = 5x

Next, we can divide both sides by 5 to isolate x:

(2y + 21) / 5 = x

Therefore, the equation 2y + 3 = 5x - 18 can be rearranged to make x the subject as x = (2y + 21) / 5.

Will give brainliest for full answer

Answers

Answer:

x = 3 and x = 8

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, then

WA = DR , substitute values

12x - 9 = 5x + 12 ( subtract 5x from both sides )

7x - 9 = 12 ( add 9 to both sides )

7x = 21 ( divide both sides by 7 )

x = 3

------------------------------------------------------

The diagonals of a parallelogram bisect each other, then

DeepSea Challenger’s descent was a change in depth of (-4) feet per second.We can use the equation y = -4x to model this relationship, where y is the depth (-35,814 ft) and x is the time in seconds that have passed. How many seconds does this model suggest it would take for DeepSea Challenger to reach the bottom?(round to the nearest tenth)
* Explain how you got your answer.

Answers

Answer:

Step-by-step explanation:

x = -35,814 ft ⋅ (1 sec)/(-4 ft) = 8,953.5 sec

The required model suggests that it would take approximately 8957.5 seconds for DeepSea Challenger to reach the bottom.

What is proportionality?

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

To find the time it takes for the DeepSea Challenger to reach the bottom, we need to find the value of x when y = -35,814 ft.

We can substitute the desired depth into the equation y = -4x:

-35,814 = -4x

35,814 = 4x

x = 35,814 / 4

x = 8953.5 seconds

So, the model suggests that it would take approximately 8957.5 seconds for DeepSea Challenger to reach the bottom.
