Step-by-step explanation:

its hard to tell but i think it dilated 5 units

We want to find the scale factor at which QRST is dilated to form Q'R'S'T'

We will find that the scale factor is 2.

In a general dilation, we will see that all the measures change in the same way, by the scale factor.

This means that:

QR*k = Q'R'

RS*k = R'S'

And so on, where k is the scale factor.

Then we can just find one of the equivalent measures in both trapezoids and find the value of k.

For example, we have:

Q'R' = 8

QR = 4

Replacing these on the above equation we get:

4*k = 8

k = 8/4 = 2

k = 2

The scale factor of dilation is 2.

Answer:

  C

Step-by-step explanation:

You want to choose the number line graph that appropriately represents the inequality 0 < x ≤ 26.

The given compound inequality is conveniently written with the "arrows" pointing to the left. This means the lower limit of the variable is on the left side of the inequality, just as it is on the left end of the number line graph.

The inequality symbols used are "less than" (<) and "less than or equal to" (≤). The "less than" symbol is represented on a number line graph by an open circle. The "less than or equal to" symbol is represented by a filled dot on the number line.

This means you are looking for a graph that has an open circle on the left end of a solid line, and a filled dot on the right end. Only graphs B and C have finite-length lines, and only graph C has a filled dot at the right end.

In English, the word "between" often implies "and including" when it is describing an interval between two limits. Here, you are given 3 car seat specifications:

The seats appropriate for a 33-lb child would be seats B and C, because 33 is included in each of those intervals.

The ordered pairs, justification of the function with different order pairs is required.

The ordered pairs are [tex](0,10),(1,9.5),(2,9),(3,8.5),(4,8),(5,7.5)[/tex]

All values of [tex]x[/tex] has a unique value in [tex]y[/tex] so, it is a function.

y = Height of candle

x = Number of hours

m = Rate = 0.5 inches per hour

c = y intercept = Initial height = 10 inches

The required function is

[tex]y=-0.5x+10[/tex]

Six ordered pairs would be

[tex]x=0,1,2,3,4,5[/tex]

[tex]y=-0.5\times 0+10=10[/tex]

[tex]y=-0.5\times 1+10=9.5[/tex]

[tex]y=-0.5\times 2+10=9[/tex]

[tex]y=-0.5\times 3+10=8.5[/tex]

[tex]y=-0.5\times 4+10=8[/tex]

[tex]y=-0.5\times 5+10=7.5[/tex]

The ordered pairs are

[tex](0,10),(1,9.5),(2,9),(3,8.5),(4,8),(5,7.5)[/tex]

It can be seen that all values of [tex]x[/tex] has a unique value in [tex]y[/tex] so, it is a function.

If m = 0.75 inches per hour

The function would change to

[tex]y=-0.75x+10[/tex]

Some ordered pairs would be

[tex]y=-0.75\times 0+10[/tex]

[tex]y=-0.75\times 1+10[/tex]

[tex](0,10),(1,9.25)[/tex]

The same is seen in this function, all values of [tex]x[/tex] has a unique value in [tex]y[/tex] so, it is a function.

Answer:

1440 hrs

Step-by-step explanation:

5 is the number of hours he works, and 45 is the total money David makes.

Two or more expressions with an Equal sign is called as Equation.

Given that David  offers his clients two different service options.

Plan A charges $20 per month plus $5 an hour.

Plan B charges $30 per month plus $3 an hour.

y = 5x + 20 and y = 3x + 30 are the system of equations to determine how much money he can make on both plans.

y = 5x + 20..(1)

y = 3x + 30..(2)

Substitute equation 2 from equation 1.

y-y=5x+20-3x-30

0=2x-10

2x=10

Divide both sides by 2

x=5.

Now substitute x in equation 1.

y=25+20

y=45

Hence, 5 is the number of hours he works, and 45 is the total money David makes.

Answer: Local Department Store: $6.5, $118.5

Across Town: $13, $102

Neighboring City: $26, $96

Step-by-step explanation:

Local Department Store: 1 hr=60 min.

60/15=4

26/4=$6.5

112+6.5=$118.5

Across Town: 60/30=2

26/2=$13

89+13=$102

Neighboring City: 60/60=1

26/1=$26

70+26=$96

The table of values is:

Time(min)           |         Distance(mi)

0                                         0

1/2                                     2/3

1                                         4/3

9/4                                      3

8                                       32/3

1) The relationship between Distance and Time is proportional.

2) The unit rate is 4/3 miles

To complete the table, we need to find the missing values of time and distance.

We use the relation between Distance, speed and time ,to find the missing values, which is given by,

Distance = Speed x Time

Given when time = 1/2 minute, the distance = 2/3 miles

Speed = Distance/Time

           = 2/3 x 2/1

           = 4/3 mile per minute.

This is the constant speed of the cheetah. We use this constant speed to find the other values to complete the table.

So If we take 'y' as the distance and 'x' as the time, then the relationship between time and distance can be expressed as

  y = (4/3)x  [since Distance = Speed x Time ].

So this relationship is proportional because there is a constant of proportionality 4/3 in the linear equation above and hence can be graphed as well.

The graph will contain the time values on the x-axis and distance values on the y-axis.

So now we need to find the missing values on the table using the above linear equation.

When time, x = 1 minute, distance, y = (4/3) x 1 = 4/3 miles.

When distance, y = 3 miles, 3 = (4/3)x

⇒ time, x = 3 x (3/4) = 9/4 minutes.

When time, x = 8 minutes, distance, y = (4/3) x 8 = 32/3 miles.

So the table is:

Time(min)            |        Distance(mi)

0                                         0

1/2                                     2/3

1                                         4/3

9/4                                     3

8                                        32/3

The unit rate refers to the y-value when the x-value is unity(1). So the unit rate here is found when time = 1 minute.

From the table, distance when time = 1 minute is 4/3 miles.

Hence, unit rate = 4/3 miles.
