True or False: The points (6,13) (21, 33) and (99, 137) all lie on the same line. The equation of the line is y = 4/3x + 5. PLS HELP ASAP

Answers

Answer:

This is true look at picture for clarification

Answer:

True

Step-by-step explanation:

To see if the points all lie on the line y = 4/3x + 5, substitute their x and y values into the equation, solve, and see if the equation is true.

1) First, substitute the x and y values of (6,13) for the x and y in the equation and solve:

[tex]13 = \frac{4}{3} (6) + 5 \\13 = \frac{24}{3} +\frac{15}{3} \\13 = \frac{39}{3}\\13 = 13[/tex]

The result is a true equation. Thus, (6,13) is on the line.

2) Do the same with the point (21,33):

[tex]33 = \frac{4}{3} (21) + 5 \\33 = \frac{84}{3} +\frac{15}{3} \\33 = \frac{99}{3} \\33 = 33[/tex]

The result is a true equation. Thus, (21,33) is on the line.

3) Finally, do the same with (99, 137):

[tex]137 = \frac{4}{3} (99) + 5\\137 = \frac{396}{3}+\frac{15}{3} \\137 = \frac{411}{3} \\137 = 137[/tex]

The result is a true equation. Thus, (99, 137).

All three points are on the line, thus the statement is true.

A snowboard was $180 but marked as 30% off. There is a state tax of 7.5%. How much would you pay for the snowboard

Answers

Answer:

180(.30)=54, 180-54=126, 126(0.075)=9.45+126=135.45

Step-by-step explanation:

The total is $135.45.

Answer:$135.45

Step-by-step explanation:

180X .30 = 54 dollars off

180-54 =126 so the board on sales costs $126

Adding the tax

126x.075 = 9.45 is the tax due

126+9.45 = 135.45

Brian has saved five dollars in dimes quarters and half dollars she finds that she has 30 coins all together and there are four times as many quarters as there are half dollars how many dimes does Brian have

Answers

9514 1404 393

Answer:

20 dimes8 quarters2 half-dollars

Step-by-step explanation:

Let d, q, h represent the numbers of dimes, quarters, and halves Brian has. We can write 3 equations in these 3 variables:

  10d +25q +50h = 500 . . . . value of the coins, in cents

  d + q + h = 30 . . . . . . . . . . . total number of coins

  4h = q . . . . . . . . . . . . . . . . . four times as many quarters as halves

Using the last equation to substitute into the other two, we get ...

  10d + 150h = 500

  d +5h = 30

The second equation can be written as ...

  5h = 30 -d

and the first can be written to facilitate substitution:

  10d +30(5h) = 500

  10d +30(30-d) = 500 . . . . . substitute for 5h

  900 -20d = 500 . . . . . . . . . simplify

  400 = 20d . . . . . . . . . . . . . add 20d-500 to both sides

  d = 20 . . . . . . . . . . . . . . . . divide by 20

Marcus bought a booklet of tickets to use at the amusement park. He used 50% of the tickets on rides, 1/10 of the tickets on video games, and the rest of the tickets in the batting cage. Marcus says he used 38% of the tickets in the batting cage. Do you agree? Complete the explanation.

Answers

Answer:

no

If he used 50% on ticket for rides, the remaining tickets he would have is (100% - 50%) 50%.

He used 1/10 on video games. Converting 1/10 to percentage gives 10%.

The total percentage of tickets used is 60%. He should have 40% to spend on batting cages

What is the percent of change from 500,000 to 800,000?

Answers

Answer:60%Step-by-step explanation:60% of 500000 is 300000500000 + 300000 = 800000

The values will vary by a percentage of 60%.

What is percentage change?

Finding the difference between two values in a time series, dividing that difference by the initial value, and multiplying by 100 are used to determine the percentage change between the two values.

Given two values 500,000 and 800,000

From the general formula of percentage change

percentage change = (final value - initial value)/ initial value * 100

Percentage change = (800,000 - 500,000)/500,000* 100

Percentage change = 60

Therefore, the percentage change of the given values will be 60%.

Melissa has her own catering service. So far this year her company has generated income of $45,750. If she charges an average of $350 for each catering job, which linear equation could be used to find the company's total (t) income after completeing jobs?

Answers

Answer:

t = 350x + 45,750

Step-by-step explanation:

The linear equation that would represent this scenario perfectly would be the following

t = 350x + 45,750

In this equation, the variable x represents the total number of catering jobs that Melissa and her company are completing. This variable gets multiplied by the cost that she charges for each individual job. Finally, the total amount of money that she has already made so far this year is added to that product to give us the total income that she would make for the year after completing the jobs.

Given:

[tex]\overline{AE}\cong \overline{DE}, \overline{AB}\cong \overline{DC}[/tex]

To prove:

[tex]\Delta ABE\cong \Delta DCE[/tex]

Solution:

In triangle AED,

[tex]\overline{AE}\cong \overline{DE}[/tex]

Two sides of triangle AED are equal, it means triangle AED is an isosceles triangle. The base angles of an isosceles triangle are equal. So,

[tex]\angle A\cong \angle D[/tex]

In triangle ABE and triangle DCE,

[tex]\overline{AE}\cong \overline{DE}[/tex]         (Given)

[tex]\angle A\cong \angle D[/tex]        (Base angles of an isosceles triangle are equal)

[tex]\overline{AB}\cong \overline{DC}[/tex]        (Given)

Two corresponding sides and their included angles are congruent. So, triangles are congruent by SAS postulate of congruence.

[tex]\Delta ABE\cong \Delta DCE[/tex]           (By SAS postulate of congruence)

Hence proved.
