determine the initial value

Answers

Answer 1

Answer:

The initial (x, y) value of the data is (0, 16)

Step-by-step explanation:

The given data is presented here as follows;

[tex]\left\begin{array}{cc}x&y\\-5&6\\-4&8\\-3&10\\-2&12\\-1&14\end{array}[/tex]

From we data, we have a common first difference in the 'y' values of 2, therefore, we have a straight line graph

The slope of the graph, m = (14 - 6)/(-1 - (-5)) = 2

The equation of the straight line graph in point and slope form is;

y - 14 = 2 × (x - (-1)) = 2 × (x + 1)

Therefore, the equation of the straight line graph in slope and intercept form is given as follows;

y - 14 = 2 × (x + 1)

y = 2·x + 2 + 14 = 2·x + 16

y = 2·x + 16

The initial value of the graph when x = 0 is therefore given as follows;

y = 2·x + 16 = 2 × 0 + 16 = 16

y = 16 when x = 0

The initial value of the graph is (0, 16)

Therefore, the initial value of the given data is x = 0, y = 16.

Find the midpoint of the line segment with end coordinates of:(−1,−6) and (4,5)
Give coordinates as decimals where appropriate.

Answers

The midpoint of the line segment with endpoints (-1, -6) and (4, 5) is (3/2, -1/2).

Finding the midpoint of the line segment

The midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is given by the coordinates:

((x1 + x2)/2, (y1 + y2)/2)

In this case, the endpoints are (-1, -6) and (4, 5), so we can plug in the values:

((x1 + x2)/2, (y1 + y2)/2) = ((-1 + 4)/2, (-6 + 5)/2)

Simplifying this expression, we get:

((x1 + x2)/2, (y1 + y2)/2) = (3/2, -1/2)

Therefore, the midpoint of the line segment with endpoints (-1, -6) and (4, 5) is (3/2, -1/2).

Answer: 24/192. She would replace the water with 8 cups of salt

Step-by-step explanation:

Select the correct answer. Victor and Dennis are weeding a garden. If Victor worked alone, it would take him 30 minutes. Working together, they would finish in 12 minutes. When x represents the number of minutes it would take Dennis working alone, this situation is represented by this equation: Working alone, how long would it take Dennis to weed the garden? A. 15 minutes B. 18 minutes C. 20 minutes D. The rational equation has no valid solutions.

Answers

Answer:

C. 20 minutes

Step-by-step explanation:

If Victor (V) worked alone, it would take him 30 minutes.

30 * V = 1

V = 1 / 30

When x represents the number of minutes it would take Dennis (D) working alone,

x * D = 1

D = 1 / x

Working together, they would finish in 12 minutes

12 (V + D) = 1

12( 1/30 + 1/x) =1

1/30 + 1/x = 1/12

Multiply all through by x

x/30 + 1 = x/12

x/30 - x/12 = - 1

( 2x - 5x ) / 60 = - 1

- 3x / 60 = - 1

- 3x = -60

x = -60 / -3 = 20 minutes

Write the function that models the relationship. z varies directly with x and inversely with y, and z = 10 when x = 5, y = 2

Answers

Answer:

z = [tex]\frac{4x}{y}[/tex]

Step-by-step explanation:

Given z varies directly with x and inversely with y then the equation relating them is

z = k × [tex]\frac{x}{y}[/tex] ← k is the constant of variation

To find k use the condition z = 10 when x = 5 and y = 2, then

10 = k × [tex]\frac{5}{2}[/tex] ( multiply both sides by 2 to clear the fraction

20 = 5k ( divide both sides by 5 )

4 = k

z = [tex]\frac{4x}{y}[/tex] ← equation of variation

The function that models the asked relationship is 4x / y

What is variation?

A variation is a relation between a set of values of one variable and a set of values of other variables.

Given that, z varies directly with x and inversely with y then the equation relating them is,

z = (k × x) / y, where, k is the constant of variation

Finding k by using the condition z = 10 when x = 5 and y = 2, then

10 = (k × 5) / 2

20 = 5k

k = 4

Therefore, the equation of variation is 4x / y

Hence, the function that models the asked relationship is 4x / y

- Mia and Lily are trying to find the nearest whole number to the square root of 120

Mia: It is 10
Lily: It is 11

Who is correct?

Give a reason for your answer.

Answers

Lily is correct

11x11=121 and 10x10 is 110 so the nearest number of the square root 120 is 11.

For determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.

Given that,

Mia has 10 number.And, Lily is 11 number.

Now if we square both the numbers so it comes:

10^2 = 10011^2 = 121

So, 121 is nearest to 120.

Therefore we can conclude that for determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.

Set up a proportional relationship and solve

If y is -6 and x will be 3 then what will y be when x is 11. \

We can represent that situation like this,

[tex]\frac{-6}{y} = \frac{3}{11}[/tex] cross multiply
