Answer:

a)  -2 -< x-<  2

b)  -1 < x and < 2

Step-by-step explanation:

We use -< as the numbers are included in the solution being -2 and 2

We use < as the numbers are less than -1 and 2

You know the difference i just couldn't copy and paste the inequalities for a).

They face the same way I have shown.

If the line on the number line were not central to 2 numbers and separate then they would face the opposite way and show two inequalities and we refer to that as or, but both of these mean and. they mean and as the line joins them together on each number line, the only difference is an open circle means the numbers are not inclusive so we dont enhance the arrow for non inclusive, when a) is inclusive we put a line underneath the arrow and still face them the left side as x shows the relationship of being inclusive still the same. a) has a line under the arrow i just couldn't show and hope you see the difference as we only use two types of arrows.

Anita has two options for how to invest $1,000. Plan A: put the 1,000 in an account that pays $100 per year. Plan B: put the 1,000 in an account that pays 5 percent interest per year. What statement is true? Plan A will be worth more than plan B after two years. Plan A will be worth more than plan B after one year. Plan B will be worth more than plan A after three years. Plan B will be worth more than plan A after four years.

Answers

Answer:

True Plan A will be worth more than plan B after two years.

True Plan A will be worth more than plan B after one year.

False Plan B will be worth more than plan A after three years.

False Plan B will be worth more than plan A after four years.

Step-by-step explanation:

plan A proves 10% Standard interest as it is $100 every year

plan B proves $50 per year Standard interest and may increase if this was CI interest as it may include interest on interest but nothing was mentioned that Plan B was CI type interest or any different from plan B type.

Because of this we can only agree option 1+2 out of 1-4 is true.

HELP! Point A is located at (3, -1). It is moved 5 units to the left and 4 units up. Its new coordinates are:

Answers

Answer:  (-2,3)

Explanation:

Subtract 5 from the x coordinate to move the point five units to the left. We go from (3,-1) to (-2,-1) after doing this.

Next up, add 4 to the y coordinate to shift the point up four units. We go from (-2,-1) to (-2,3)

Answer is    (-2,3)

===========================================================

Explanation:

Subtract 5 from the x coordinate to move the point five units to the left. We go from (3,-1) to (-2,-1) after doing this.

Next up, add 4 to the y coordinate to shift the point up four units. We go from (-2,-1) to (-2,3)

See diagram below. Point A is the initial point, B is the second step, and C is the final destination.

Another way to write out the steps is to use the transformation rule below

a pair of shoes is originally priced at 120 It is on sale for 35% off . Find the total percent that you would pay

Answers

Step-by-step explanation:

If the discount is 35% off. then the new price is 65% of what the old price is. So we multiply 120 x .65 = 78

Answer:

You pay 65% which is $78

Step-by-step explanation:

You'd pay 65% of the original price.

65% of the original price is 78

To do this you multiply 65% by 120

Oil prices are projected to increase by 125% by next August. A quart of oil currently costs $1.25. What is the projected cost of a gallon of oil next August? Round your answer to the nearest hundredth.

Answers

Answer:

$2.81

Step-by-step explanation:

1.25 is 100% of the price

125% + 100% = 225%

x = price by august

x = 225% (1.25)

225% = 2.25

2.25(1.25) = 2.8125 ≈ $2.81

Another way to see it:

[tex]\frac{1.25}{x}[/tex] = [tex]\frac{100}{225}[/tex]

225(1.25) / 100 = 2.8125

Answers

Answer:

A. Yes, because it passes the vertical line test.

Step-by-step explanation:

The vertical line test requires you to draw a vertical line through any part of the graph. If the line intersects the graph at only one point, the graph represents a function. This graph passes that test. As for the other answer choices, the "horizontal line test" is not a way to see if a graph represents a function. I hope this helps :))

Answer:

A. Yes, because it passes the vertical line test.

Step-by-step explanation:

The vertical line test states that you can draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function. In this case, the line doesn't intersect the graph more than once.
