Explanation:

The value of k determines the slope, or rate of change, of how fast the balloon is climbing per second.

For example, if k = 5, then that means the balloon is going upward at 5 feet per second (equivalent to roughly 3.41 mph)

If k = 5, then y = kt becomes y = 5t. Note how we have the following

and so on. Each time t goes up by 1, d goes up by 5. This is one way to see how the speed is 5/1 = 5 ft per second.

Answer:X = Daniel spent

Y = Tracy spent

Tracy spent = Y

$38 less than = -38

3 times Daniel spent = 3X

Put it all together

Y=3X-38

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

Answer:

(-1.714, 1.857)

Step-by-step explanation:

Here, we want to find the approximate solution to the system of linear equations

We start by plotting the graph of the lines

We have the plot as shown below;

the red line represents the first equation while the blue line represents the second equation

We have the solution as the point at which the two lines meet

The solution to this is;

(-1.714, 1.857)

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

Answer:

C. -8

Step-by-step explanation:

Don't listen to ppl who say it's 3, IT'S NOT. The answer is C. y= -8, because the line has to be parallel so it will be y and D is clearly not correct, so its C.

Answer:

c=-8

Step-by-step explanation:

only answer that makes sense i just took the test

[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.

Answer:

4*6=24     answer:6

any other number would be less or more

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

4 x 6 is 24 and 4 x 7 is 28. 26 is between 24 and 28, so got to 24 since that is less than 26. 4 x 6 gets you 24, so 6 is your answer.

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.

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.

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

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

QS = [tex]\frac{1}{2}[/tex] QT , that is

8x - 14 = [tex]\frac{1}{2}[/tex] × 100 = 50 ( add 14 to both sides )

8x = 64 ( divide both sides by 8 )

x = 8

x = 3 and x = 8
