Answer:

Length = 15

Step-by-step explanation:

The problem can be solved by dividing the total length of the rope (90-feet) by the total pieces you want from the rope (6 pieces). This information can be used to make this equation

90 feet / 6 pieces

Which equals

90 feet / 6 pieces = 15 feet/piece        (15 feet per peice)

The equation for the hourly rate is 55x = 1578.5

For double hourly rate for overtime, it is 55 x 2x= 1578.5

Given

Antonia makes X dollars for regular hours

And 2x dollars for over time

Since he works 55 hours this week he works 8 hours a day

Hence the equation is as follows

55x = 1578.5

x= $28.7

In case of double payment during overtime

He gets double amount as following equation

55 x 2x

55 x 2(28.7) =  $3157

Hence the equation to find his hourly rate is 55x = 157.85

The equation best compares the slopes of two functions is,

Slope of function B = 2 × Slope of function A

Given,

The function A, f(x) = x - 9

We have to find slope of Function B

The function is in the form of y = mx + b

Here, m is the slope.

y = x - 9

m is 1 and b is -9

Now, lets consider the graph of line passing through points (-1, -3) and (2, 3)

That is,

(x₁, y₁) = (-1, -3)

(x₂, y₂) = (2, 3)

Now we can find the slope of the line:

m = (y₂ - y₁) / (x₂ - x₁)

m = (3 - (-3)) / (2- (-1))

m = (3 + 3) / (2 + 1)

m = 6/3

m = 2

That is, the slope of function B is 2

Here,

Slope of function A is 1.

That is, slope of function B is twice the slope of function A.

Therefore, the equation best compares the slopes of two functions is,

Slope of function B = 2 × Slope of function A

We know that G is on the line, and we know the length FG and GH, so we can represent this as:

We then, we can apply the rule that states that the length of a segment is equal to the length of the segments that are part of it:

Answer: FH = 15

Answer: 5/3

Step-by-step explanation:

The scale factor is the same as the ratio of the length of a side of the image to the length of the corresponding side in the preimage.

We know that N'Q'=10 and NQ=6, so the scale factor is 10/6 = 5/3.

The value of x if T is the midpoint segment XY is 14.

The midpoint is the middle point of a line segment.

It is equidistant from both endpoints.

The midpoint is halfway between the two end points.

Therefore, the end point of the segment is XY.

The midpoint is T.

Hence,

XY = XT + YT

XT = 3x - 14 = YT

XY = 8x - 56

Let's find the value x.

Therefore,

8x - 56  = 3x - 14 + 3x - 14

8x - 56 = 6x - 28

8x - 6x = -28 + 56

2x = 28

divide both sides by 2

x = 28 / 2

x = 14

Therefore, the value of x is 14

Using simple interest, the amounts invested into each account are given as follows:

Simple interest is used when there is a single compounding per time period.

The amount of money after t years in is modeled by:

A(t) = P(1 + rt)

In which:

The amount of interest after t years is given by:

I(t) = Prt

You invest $8,000 in 3 investment accounts, hence:

[tex]P_1 + P_2 + P_3 = 8000[/tex]

From the rates of the account, we have that:

The amount invested in the glass account was double the amount invested in the metal account, hence:

[tex]P_3 = 2P_2[/tex]

The yield was a total of $280 at the end of one year, hence:

[tex]I_1 + I_2 + I_3 = 280[/tex]

[tex]0.02P_1 + 0.04P_2 + 0.05P_3 = 280[/tex]

From the first and the third equations, we have that:

[tex]P_1 + P_2 + P_3 = 8000[/tex]

[tex]P_1 + 3P_2 = 8000[/tex]

[tex]P_1 = 8000 - 3P_2[/tex]

Hence the amount of the metal investment can be found as follows:

[tex]0.02P_1 + 0.04P_2 + 0.05P_3 = 280[/tex]

[tex]0.02(8000 - 3P_2) + 0.04P_2 + 0.05(2P_2) = 280[/tex]

[tex]0.08P_2 = 120[/tex]

[tex]P_2 = \frac{120}{0.08}[/tex]

[tex]P_2 = 1500[/tex]

Step-by-step explanation:

The graph of the absolute value function is an inverted "V" such that the vertex is at (-4, -5) and opens downwards.

We call a modular function the function f(x) = |x|, in which its domain is given by the real numbers and its range is the positive real numbers. This is because, for every negative value on the y-axis, the modular function will make |-y| = -(-y) = y

Therefore, to plot the graph of a modular function, it is enough to adopt some values ​​for x and apply them to the function f(x) = | x |, in order to obtain their respective values ​​in y.

Answer:

s=3

Step-by-step explanation:

So you have the equation: [tex]\frac{6}{s}=2[/tex]

If we multiply both sides by this "s" value we should maintain equality, and it conveniently cancels out our division by "s" on the left side giving us the following equation: [tex]6=2s[/tex]

The only "operation" on the value "s" is the coefficient of 2, which is multiplying the value of "s" by 2.

To undo this multiplication of 2, we simply divide by 2, since 2/2 = 1, and now we have a coefficient of 1 for the "s", which is the same as isolating "s"

But we want to divide both sides by 2 to maintain equality, so let's write out our expression

[tex]\frac{6}{2}=\frac{2s}{2}\implies3=\frac{2}{2}*s\implies 3=s[/tex]

We can double check this by plugging in this value for "s" in the original equation: [tex]s=3, \ \frac{6}{s}=2\implies \frac{6}{3}=2\implies 3=3[/tex] which is indeed true, so we have our solution!

By solving the given equation (y = 0.43x + 5) we know that the cost of renting the car is $215 when we plan to drive 489 miles.

So, y = 0.43x + 5 where 'x' is car driven and 'y' is the cost of renting.

Now, solve for y when the value of x is 489.

Rounding off: y = $215
