Write An Equation In The Form Of Y=kx For The Graph Below. (k=y/x) K Is In DecimalForm

Answers

Answer 1

Answer:

k = 3.5

Step-by-step explanation:

From the graph in the picture attached,

Relation between balloons height (y) is directly proportional to the time (x)

y ∝ x

y = kx

Where 'k' is a proportionality constant.

Now we substitute the point (8, 28) in the equation,

28 = k(8)

k = [tex]\frac{28}{8}[/tex]

k = 3.5

k ≈ 3.5

Therefore, value of constant 'k' is 3.5

As a restaurant manager, you are tracking the number of ketchup bottles used each week in the restaurant. For six
weeks, the number of bottles used each week were 10, 14, 11, 10, 18, and 17.
What is the mean number of ketchup bottles used in one week?
A. 8
B. 10 C. 35/3
D. 40/3
E. 14

Answers

Answer:

The mean is 40/3 ⇒ D

Step-by-step explanation:

The mean of a set of data = The sum of data ÷ the number of data

∵ A restaurant manager tracking the number of ketchup bottles in

  six weeks

∴ The number of data = 6

∵ The numbers of ketchup bottles used each week are 10, 14, 11, 10, 18, 17

→ Find their sum

∴ Their sum = 10 + 14 + 11 + 10 + 18 + 17

∴ Their sum = 80

∵ The mean = The sum of data ÷ the number of data

∴ The mean = 80 ÷ 6

→ Simplify it by dividing both by 2

∴ The mean = 40/3

Barney earns $24.75 in 3 hours if the amount that Barney earns varies directly with the number of hours, how much would he earn in 20 hours.

Answers

Answer:

$165

Step-by-step explanation:

Divide 24.75 by 3 to get how much Barney(lol) would get in a hour then I got 8.25 so 8.25 x 20 hours = $165

Answer:

165$ in 20 hours

Step-by-step explanation:

Barney earns 24.75 in 3 hours, so 24.75 / 3 is 8.25. This is every hour so you would take 8.25 and multiply it by 20. That gives you 165

Answer:

  x = -2 and x = 1/3

Step-by-step explanation:

The simple way to solve this is to enter the equation into a graphing calculator and have it show you what the zeros are.

The solutions are x = -2 and x = 1/3.

__

One way to solve this is to factor it. The product of the leading coefficient and the constant is (3)(-2) = -6. You want to find factors of this number that have a sum equal to the coefficient of the linear term: 5.

  -6 = (-1)(6) = (-2)(3) = ...

The first pair of factors listed here has a sum of 5, so we can rewrite the equation as ...

  3x^2 -x +6x -2 = 0

Factoring pairs of terms, we have ...

  x(3x -1) +2(3x -1) = 0

  (x +2)(3x -1) = 0

The solutions are the values of x that make these factors zero:

  x + 2 = 0   ⇒   x = -2

  3x -1 = 0   ⇒   x = 1/3

The solutions are x = -2 and x = 1/3.

What is the y-intercept of the line whose equation is y = x - 3?

-3
1/2
3

Answers

Answer:

-3

Step-by-step explanation:

y=0-3

y=-3

By definition,  the correct answer is the first option: the y-intercept is -3.

A linear equation o line can be expressed in the form y = mx + b.

where

x and y are coordinates of a point. m is the slope. b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

The ordinate to the origin is the value where the line intersects the axis. Thus, the value of x must be 0 for this to occur.

In this case you know that the form of the linear equation is y=x-3.

Being x=0, then:

y=0-3

y= -3

Finally, the correct answer is the first option: the y-intercept is -3.

Answers

Answer:

Step-by-step explanation:

10) From the diagram you can see that the diagram at the right hand side is am isosceles triangle. An isosceles triangle is triangle that has its two base angles equal. Hence

x = 75°

Reason: Base angle of an isosceles triangle are equal.

To get y:

First we need to find the third angle of the isosceles triangle. Let's take the angle as p

Since sum of angle in a triangle is 180°, then

p+ 75 +x = 180

p+75+75 = 180

p+150=180

p = 180-150

p = 30°

To get y:

Know that the y + p = 90° (right angled)

y + 30 = 90

y = 90-30

y = 60°

Hence x = 75° and y = 60°

b)Note that the triangle in the middle is an equilateral triangle. The sum of angle in a triangle is 180°

Hence all the angles are 60°

To get x;

Sum of angle on the straight line is expressed as;

40°+60°+x° = 180°

100°+x = 180°

x = 180°-100°

x = 80°

Also since the lines are parallel, the angle at the right corner of the triangle is also 40° (corresponding to that angle at the corner of the first triangle)

To calculate y;

Sum of angle in the triangle at the right is 180° hence;

x+y+40 = 180

80+y+40=180

120+y = 180

y = 180-120

y = 60°

Hence the value of x and y are 80° and 60° respectively.

After the 1000s which kingdom became a center for Christianity in africa The effects of the development of trans-Saharan trade networks on West African states can be better understood by considering the earlier development of cities and states in the region. Due to the difficulty of raising livestock and growing crops in the hot Sahara, the economy of West Africa lagged behind that of North Africa until the growth of trade. Likewise, while a sophisticated civilization developed in the Niger Valley after 300 BCE, growing trade cities at the time were not joined into a larger empire. The ongoing development of trans-Saharan trade, however, provided the resources for economic and political change in the region. Review the sample essay excerpt above.
