Answer:

{x | x ≤ -8}

Step-by-step explanation:

-7x ≥ 56

Divide each side by -7, remembering to flip the inequality since we are dividing by a negative

Which scenario reflects an annual inflation rate of 2%? In year 1, the price of a tire is $100. In year 2, the same tire costs $

katrin [286]

Answer:

The correct answer is 2. 2. In year 1, the price of a candy bar is $0.50. In year 2, the same candy bar is $0.51.

Price of candy bar in Yr 2 should be = 0.50 * 1.02 = 0.51

This scenario reflects an inflation of 2%.

Step-by-step explanation:

Let's check each scenario and select the one that reflects an annual inflation rate of 2%.

1. In year 1, the price of a tire is $100. In year 2, the same tire costs $120.

Price of tire in Yr 2 should be= 100 * 1.02 = 102

This scenario reflects an inflation of 20%. Not the one we're looking for.

2. In year 1, the price of a candy bar is $0.50. In year 2, the same candy bar is $0.51.

Price of candy bar in Yr 2 should be = 0.50 * 1.02 = 0.51

This scenario reflects an inflation of 2%. This is the correct answer.

3. In year 1, the price of a pair of shoes is $30. In year 2, the same pair of shoes is $32

Price of pair of shoes in Yr 2 should be= 30 * 1.02 = 30.60

This scenario reflects an inflation of 6.7%. Not the one we're looking for.

4. In year 1, the price of a pair of headphones is $20. In year 2, the same pair of headphones is $21.

Price of pair headphones in Yr 2 should be= 20 * 1.02 = 20.40

This scenario reflects an inflation of 5%. Not the one we're looking for.

When given the information below, can you conclude that Quadrilateral WXYZ is a parallelogram? Why or why not?

Masja [62]

B) No, because opposite sides are not parallel

Step-by-step explanation:

Given this information, assume that quadrilateral WXYZ is a parallelogram then we expect;

Parallel sides to be : WX // YZ and XY // WZ

Additionally, we know parallel sides have equal gradient thus;

The slope of side WX= slope of side YZ and the slope of side XY= that of side WZ

However, from the information given, m of WX= 1/3 and that of YZ is -3, thus the two sides are not parallel to each other but perpendicular to each other because the product of their slope equals -1.

Round 117.22666 to the nearest tenths

zzz [600]

Answer:

117.2

Step-by-step explanation:

Rounding a number to the nearest tenth:

A number rounded to the nearest tenth will have one decimal place.

To do this, we look at the second decimal digit.

If it is less than 5, the first decimal digit is kept.

Otherwise, one is added to the first decimal digit.

In this question:

117.22666

The second decimal digit is 2, which means that we keep the first decimal digit which is also 2.

So, the number rounded to the nearest tenth is 117.2.
