The figure shows three quadrilaterals on a coordinate grid:

A coordinate grid is shown from positive 8 to negative 8 on the x-axis and from positive 8 to negative 8 on the y-axis. An image of a rectangle labeled A is shown on ordered pair 1, 1 and 3, 1 and 3, 2 and 1, 2. Another image of a rectangle labeled B is shown on ordered pair 2, 2 and 6, 2 and 6, 4 and 2, 4. Another image of a rectangle labeled C is shown on ordered pair negative 1, 1 and negative 1, 2, and negative 3 , 2 and negative 3, 1.
Which of the following statements is true about the three quadrilaterals? (5 points)

a
A and B are similar but not congruent.

b
A and C are similar but not congruent.

c
A and B are similar and also congruent.

d
B and C are similar and also congruent.

Solve for a:

3a +11 > 5

Subtract 11 from both sides:

3a >-6

Divide both sides by 3:

a > -6/3

a > -2

The Correct graph is the second one, because it has the dot on the -2 and the arrow points to the right

The 2 number line shows the solutions to the inequality 3a + 11 > 5 and the correct option is B.

The image shows two number lines, and asks which one shows the solutions to the inequality 3a + 11 > 5.

To solve this inequality, we can subtract 11 from both sides, and then divide both sides by 3. This gives us a simpler inequality: a > -2.

This means that all values of a that are greater than -2 are solutions to the inequality. On a number line, this can be represented by an open circle at -2, and an arrow pointing to the right.

The number line on the left of the image shows exactly this. Therefore, the number line on the left shows the solutions to the inequality 3a + 11 > 5.

The number line on the right of the image does not show the solutions to the inequality correctly. The open circle at -2 is missing, and the arrow points to the left, which is incorrect, since the solutions to the inequality are all values of a that are greater than -2, not less than -2.

Here is a more detailed explanation of the steps involved in solving the inequality:

1. Subtract 11 from both sides:

3a + 11 > 5

-11 - 11

3a > -6

2. Divide both sides by 3:

3a > -6

3 / 3

a > -6 / 3

3. Simplify:

a > -2

Therefore, the solution to the inequality is a > -2. On a number line, this can be represented by an open circle at -2, and an arrow pointing to the right.

The number line on the left of the image shows exactly this. Therefore, the 2 number line on the left shows the solutions to the inequality 3a + 11 > 5 and the correct option is B.

A function with direct variation is a linear function that passes through the origin (0, 0) and has a constant rate of change, the slope. Only the line passing through (negative 1, negative 4), (0, 0), and (1, 4) from the given options fulfills these conditions.

In Mathematics, a function with direct variation is a linear function that passes through the origin (0, 0).  It can be represented as the equation y = mx, where m is the slope of the line. The slope of the line determines if it is a direct variation. If it's a positive slope, y increases as x increases. If it's a negative slope, y decreases as x increases.

From the given options, only the coordinate plane with a line passing through (negative 1, negative 4), (0, 0), and (1, 4) represents a function with direct variation as it's a straight line passing through the origin.

basically the order of operations states you deal with parentheses first then indices then either division/multiplication and then addition/subtraction

So when you deal with 3- 1=2

the only operation left is multiplication(something in parenthesis stuck on another mathematical term without any other operation attached to it signals multiplication and it is commutative so it can be done in any pair. so u have 4×2×2=16

Final answer:

The volume of the earth is approximately 1.0839 x 10¹⁵ cubic miles.

Explanation:

To find the volume of the earth, we can use the formula for the volume of a sphere: V = (4/3)πr³. Since we are given the diameter of the earth, we can calculate the radius by dividing the diameter by 2. In this case, the diameter is 7917.5 miles, so the radius is 3958.75 miles. Now, we can substitute the radius into the formula to find the volume:

V = (4/3)π(3958.75 miles)³

V ≈ 1.0839 x 10¹⁵ cubic miles.

Answer:

each book costs $13

Step-by-step explanation:

Let the cost of each book be $x

cost of buying 8 books = $8x

It is given that with an original amount of $116, after buying 8 books, he had $12 left over. Hence,

$8x + $12 = $116   (dropping the $ signs)

8x + 12 = 116

8x = 116 - 12

8x = 104

x = 13  (each book costs $13)

Answer:

he possibly spent $13 on order to end up with $12 left.

Step-by-step explanation:

1) look. at the number 116 you can use a calculator.

2) if 14 only leaves you with nothing you take it away

3) add 13 + 8X that should give you 104

4). substract 116-104 your total should be $12

The inverse function of f(x) = -0.75x is [tex]\(f^{-1}(x) = -\frac{4}{3}x\)[/tex].

To find the inverse function [tex]\( f^{-1}(x) \)[/tex]for the given function f(x) = -0.75x , you can follow these steps:

1. Start with the original function:

   f(x) = -0.75x

2. Replace f(x)  with y:

   y = -0.75x

3. Swap x and y to solve for x:

x = -0.75y

4. Solve for y:

  Divide both sides by -0.75:

[tex]\( y = \frac{x}{-0.75} )\\ \( y = -\frac{4}{3}x \)[/tex]

5. Replace y with [tex]\( f^{-1}(x) \)[/tex]:

[tex]\( f^{-1}(x) = -\frac{4}{3}x \)[/tex]

Answer:

the numbers are 3 and 5

Step-by-step explanation:

x = first number

y = second number

a.        x+2 = y

b.        x^2 + y^2 = 34

Replace y from equation a into equation b:

x^2 + (x+2)^2 = 34

Expand it

x^2 + x^2 + 4x + 4 = 34

2*x^2 + 4x = 30

2x^2 + 4x - 30=0

solving x:

x = -5 and x =3 , it says it is a positive number, then it is x is 3

and the second number, y = x + 2

y = 5

Lets test it!

3^2 + 5^ 2 = 9 + 25 = 34

However, it is quite common to see health insurance costs and Social Security taxes deducted from gross pay.

Answer:

Step-by-step explanation:50,897 is in standard form.

Expanded form is adding all your place values which is 50,000+800+90+7. There was a 0 in the thousand place so you do not add anything for that place value.

So (5×10,000) + (8×100) +(9×10)+(7×1) which is each number times it place value then add them all up.

Answer:

(- 1, 9 )

Step-by-step explanation:

A translation of 3 units left, subtract 3 from the original x- coordinate

A translation of 1 unit up, add 1 to the original y- coordinate.

The rule is (x, y ) → (x - 3, y + 1 ), thus

(2, 8 ) → (2 - 3, 8 + 1 ) → (- 1, 9 )

The image point of (2,8) is (-1,9).

The term P', which is pronounced "P prime," is used to refer to the reflection of point P across the line, which is considered to be the "image" of point P.

Given point is (2,8).

And the translation is left 3 unit and up 1units of the point (2,8)

By increasing or decreasing the output or the input, you may change the direction of the function's graph to the right, left, up, or down. A function's output can be increased to shift the graph up. The graph is shifted downward when a function's output is subtracted from.

That means -3 and +1 respectively.

Now the image point of (2,8)

= (2-3, 8+1)

= (-1, 9)

Therefore, the image point is (-1,9).

When Jonathan stops to tie his shoelaces four times, each adding 2 1/2 minutes, his jog takes an extra 10 minutes in total.

Explanation:

Jonathan stops to tie his shoelaces four times during his jog. Each time he stops, it adds 2 1/2 minutes to his total jog time. To find out how much longer his jog takes, we need to multiply the number of stops by the additional time per stop.

Let's calculate this step by step:

So, if Jonathan stops to tie his shoelaces four times, his jog will take an extra 10 minutes in total.

Final answer:

The integer representing the temperature drop of 28°, leaving the thermometer at 48°, is -28. The original temperature before the drop was 76°.

Explanation:

The integer that represents the number of degrees the temperature drops when the temperature drops 28° and the thermometer reads 48° afterwards is -28. To find this, we use the final temperature (48°) and add the temperature drop (28°) to determine the original temperature. However, since it is a temperature drop, we have to add a negative sign to the drop, making it -28°. Therefore, the original temperature was 48° + 28° = 76°. The decrease in temperature is represented by the negative integer -28°.
