What of following best describes the expression 9(x+7)

Answer:

A IS THE ANSWER

Step-by-step explanation:

A.birch Street is horizontal. A perpendicular street would have to be vertical. Elm Street is not vertical. Birch Street has 0 slope. Elm Street would have to have undefined slope to be perpendicular to Birch Street

Answer:

B) The local property tax

Step-by-step explanation:

A) The mortgage principal and interest payment - This does not depend on the owner's home value. These depend on the loan amount borrowed from the bank. The monthly payments will be the same irrespective of the owner's home value being going up or down.

B) The local property tax - This is the right answer as the local taxes depend on the prices in the area or neighborhood. Like posh areas have high property taxes.

C) The mortgage interest rate  - This is not right. This depends on the bank that how much interest rate it will give you depending on your credit history.

D) The cost of utilities such as heating and electricity - This is also not right as these costs are standard for a state. Everyone will have the same per unit rates for electricity.

The percent 312% of 12.5 is 39

Suppose the value of a thing is expressed in percentage is "a'

Suppose the percent that thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus will first divide the whole part in 100 parts and then we multiply it by b so that we collect b items per 100 items.

We need to Write the percent of 12.5 is 39

X%

So, we can rewrite it as

X% x 12.5 = 39

x/100 (12.5) = 39

x = 39/0.125

x = 312

To find the length of the longest side of the triangle, use the Pythagorean theorem to solve for x and determine the side lengths of the triangle.

To find the length of the longest side of the triangle, we need to determine which side is the hypotenuse. In a right triangle, the hypotenuse is the side opposite the right angle. Using the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides, we can find the length of the hypotenuse.

Let's denote the three sides of the triangle as A, B, and C. The left side is 2x + 12, the bottom side is 6x - 2, and the right side is 5x - 9. Since we can't determine which side is which based on the given information, we can use the variables.

By applying the Pythagorean theorem, we can set up the equation (2x + 12)^2 + (6x - 2)^2 = (5x - 9)^2. Expanding and simplifying this equation will allow us to solve for x and find the lengths of the sides of the triangle. Once we have the side lengths, we can determine which side is the longest.

Divide the given inequality 6x > -24 by 6 to isolate x, resulting in x > -4, which in interval notation is (-4, ∞). The correct choice is D. ( -4, ∞) ].

To solve the inequality 6x > -24, we will divide both sides of the inequality by 6 to isolate x, keeping in mind that since 6 is positive, the direction of the inequality will remain the same.

Step-by-step solution:

Start with the inequality 6x > -24.

Divide both sides by 6, which gives us x > -4.

In interval notation, this translates to (-4, ∞).

The correct choice is D. ( -4, ∞) ]

Step-by-step explanation:

Answer:

1. None of these.

2. None of these (Supplementary angles ).

3. Corresponding angles.

4. Alternate exterior angles.

5. Corresponding angles.

Step-by-step explanation:

In figure 1, the two lines are not parallel to each other, therefore we can not establish any relation between both angles. The required option is none of these.

In figure 2, both angles 1 and 2 lie on a straight line, therefore both angles are  supplementary angles and the required option is none of these.

In figure 3, both angles have same relative position, therefore both angles are  corresponding angles.

In figure 4, both angles are on the exterior of and , but on opposite sides of the transversal line, therefore both angles are alternate exterior angle.

In figure 5, both angles have same relative position, therefore both angles are  corresponding angles.

Given that an angle is 34 degrees less than its supplementary angle and knowing that supplementary angles add up to 180 degrees, the two angles measure 73 degrees and 107 degrees respectively.

To solve this problem, let's assume that the measure of the supplementary angle is x degrees. Since the angle in question is 34° less than the measure of the supplementary angle, we can set up the equation: x - 34 = the angle in question. Now, since supplementary angles add up to 180°, we can set up another equation: x + (x - 34) = 180. Solving this equation, we find that x = 107°. Therefore, the measure of the supplementary angle is 107° and the angle in question is 107° - 34° = 73°.

An angle measures 34° less than the measure of a supplementary angle. By definition, supplementary angles add up to 180°. Let's call the first angle x. Then the supplementary angle would be x + 34° because it's 34 degrees more than x. Since they are supplementary, the sum of these two angles should be 180 degrees:

x + (x + 34°) = 180°
2x + 34° = 180°
2x = 180° - 34°
2x = 146°
x = 146° / 2
x = 73°

Therefore, the measure of the first angle is 73°, and the measure of its supplementary angle is 107° (73° + 34°).

The cost of a single burger is $4.75 and that of fries is $2.5.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators

Given is that → 4 burgers and 3 fries cost $26.50 and 5 burgers and 5 fries cost $36.25.

Assume that the cost of each burger is $x and that of fries is $y. We can write the system of equations as -

4x + 3y = 26.5        ........ Eq[1]

5x + 5y = 36.25       ........... Eq[2]

We can write Eq[2] as -

5x + 5y = 36.25

x + y = 7.25

y = 7.25 - x

So, Eq[1] can be written as -

4x + 3(7.25 - x) = 26.5

4x - 3x + 21.75 = 26.5

x = 26.5 - 21.75

x = 4.75

and

y = 7.25 - x

y = 7.25 - 4.75

y = 2.50

Therefore, the cost of a single burger is $4.75 and that of fries is $2.5.

Answer:

The length of CC' is, [tex]\sqrt{29}[/tex]units

Step-by-step explanation:

Using distance(D) formula for any two points is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

As per the statement:

From the graph:

The coordinates of C and C' are:

C = (2, 2) and C' = (7, 4)

Apply the distance formula to find length CC', we have;

[tex]CC'= \sqrt{(7-2)^2+(4-2)^2}[/tex]

⇒[tex]CC'= \sqrt{(5)^2+(2)^2}[/tex]

⇒[tex]CC'= \sqrt{25+4}[/tex]

Simplify:

[tex]CC'= \sqrt{29}[/tex]

therefore, the length of CC' is, [tex]\sqrt{29}[/tex] units
