Omar shops for a new television. He finds the same television at two different stores priced at $259.99. One store offers a mail-in rebate of $75. At a different store, the television is 30% off the regular price. At which store will Omar receive the better deal? Why?

Answers

At the second store. Because 30% Of 259.99 is more than 75$.

Step-by-step explanation:

store 1.

259.99 - 75 = 184.90

stode 2.

259.99 * 30% = 78

Marisa saved $3000 to take a bike trip from Florida to California. She estimated her expenses to be $40 per day. The cost of a ticket to fly back is $240. The inequality below can be used to find the maximum number of days (d) for which Marisa can pay the expenses on the bike trip.

40d + 240 ≤ 3000

Which inequality expresses the maximum number of days Marisa can pay the expenses for her bike trip?
d≤81
d≤75
d≤69
d≤40

Answers

Answer: d≤69

Step-by-step explanation:

You would plug in all the values for d into the inequality

40(81) + 240 ≤ 3000

40(81) + 240 = 3000

3240+240=3000

3480=3000 false

40(75) + 240 ≤ 3000

40(75) + 240 = 3000

3000+240=3000

3240=3000 false

40(69) + 240 ≤ 3000

40(69) + 240 = 3000

2760+240=3000

3000=3000 true

You don't need to try the last one because you already found this one!

The inequality expresses the maximum number of days Marisa can pay the expenses for her bike trip will be d ≤ 69.

What is inequality?

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Marisa saved $3000 to take a bike trip from Florida to California.

She estimated her expenses to be $40 per day.

The cost of a ticket to fly back is $240.

The inequality below can be used to find the maximum number of days (d) for which Marisa can pay the expenses on the bike trip.

40d + 240 ≤ 3000

Substitute all the values for d into the inequality

For, d≤81

40(81) + 240 ≤ 3000

40(81) + 240 = 3000

3240+240=3000

3480=3000 false

For, d≤75

40(75) + 240 ≤ 3000

40(75) + 240 = 3000

3000+240=3000

3240=3000 false

For, d≤69

40(69) + 240 ≤ 3000

40(69) + 240 = 3000

2760+240=3000

=3000

therefore, LHS = RHS

Hence, d ≤ 69 is true.

The triangle with vertices L (-2,5), E (1,4), and (2,-2) is translated 4 units left, 3 units up, and then reflected over the line y=4 to form the image triangle L’E’D. Which vertex of the image is the greatest distance from the origin?

Answers

Answer:A

Step-by-step explanation:

The vertex of the image L'(6,8) is the greatest distance from the origin.

Explanation of how reflection across axis works?

When a graph is reflected along an axis, say the x-axis, then that leads the graph to go just on the opposite side of the axis as if we're seeing it in a mirror.

Since each point is equidistant from the axis of reflection as that of the image of that point. Thus, if we reflect a point (x,y) along the x-axis, then its x abscissa will stay the same but y ordinates will negate. Thus (x,y) turns to (x, -y)

Given that a triangle with vertices L (-2,5), E (1,4), and D (2,-2) is translated 4 units left, 3 units up, and then reflected over the line y=4 to form the image triangle L’E’D'.

If we subtract 4 from each x number and add 3 to each y number and then reflect over the line y=4 so then that would give each distance.

L (-2,5) --  L (-2 - 4,5 - 4 )

L'(6,8)

Resulting that L'(6,8) being the farthest from the origin (0,0)

what ratio forms a proportion with 8/36 ?
a. 1/4
b.6/27
c.7/30
d.2/7

Answers

6/27 bc (6/27)=(8/36)= 216/216= they are the same or 2/9=6/27=8/36

The ratio 6/27 forms a proportion of 8/36 which is the correct answer that would be an option (B).

What is the proportion?

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

The ratio is given in the question:

8/36

The above ratio can be rewritten as:

(2 × 2 × 2)/(3 × 3 × 2 × 2)

Cancel out the same number in the ratio

2/(3 × 3)

2/9

As per option (B), we

6/27

The above ratio can be rewritten as:

(2 × 3)/(3 × 3 × 3)

2/(3 × 3)

2/9

Thus, the ratio 6/27 forms a proportion of 8/36.

Hence, the correct answer would be option (B).
