Answer:

II. 8

III. 2

Step-by-step explanation:

Solving an inequality

9 ≤ 3x +4

Subtract 4 from each side

9-4 ≤ 3x +4-4

5 ≤ 3x

Divide each side by 3

5/3 ≤ 3x/3

5/3 ≤ x

x must be greater than or equal to 5/3

I. - 7  this is not greater than or equal to 5/3

II. 8   this is  greater than or equal to 5/3

III. 2 this is  greater than or equal to 5/3

The equation that represent the relationship model that will reach $0 in the same number of days as the scenario gave is: y = -2x + 12

To solve this problem, we have to state the equation using the information of the problem.

Information about the problem:

Writing the equation according to the information gave, we have:

y = -2x + 12

Where:

So that (y) equals zero, the number of days (x) should be = 6

y = -2x + 12

0 = -2*6 + 12

0 = -12 + 12

0 = 0

The "y" variable is the dependent variable, because it will change according to the number of days passed (x).

The "x" variable is the independent variable, because it doesn't depend on any other value, just the number of days passed.

An equation is the equality between two algebraic expressions, which have at least one unknown or variable.

Answer:-1a+2

Step-by-step explanation:

add like terms

Hey there!

(2a - 5) - (3a + 5)

= 2a - 5 - 3a + 5

COMBINE the LIKE TERMS

= (2a - 3a) + (-5 + 3)

= 2a - 3a + (-5) + 3

= -1a - 2

Therefore, your answer should be:

-1a - 2

Answer:

In the graph, the coordinate point (4,-9) is a vertex

In the graph, the coordinate point (1,0) is an x-intercept

In the graph, the coordinate point (7,0) is an x-intercept

In the graph, the coordinate point (4,0) is on the line of symmetry.

Explanation:

The x-intercepts are the points where the parabola crosses the x-axis, so the coordinates of the x-intercepts are (1, 0) and (7, 0)

The y-intercept is the point where the parabola crosses the y-axis, so the y-intercept is (0, 7)

The vertex is the minimum point of the parabola, in this case, (4, -9).

The line of symmetry depends on the first coordinate of the vertex, so the line of symmetry is x = 4. It means that any point with a first coordinate equal to 4 is on the line of symmetry.

Then, the answers are:

In the graph, the coordinate point (4,-9) is a vertex

In the graph, the coordinate point (1,0) is an x-intercept

In the graph, the coordinate point (7,0) is an x-intercept

in the graph, the coordinate point (4,0) is on the line of symmetry.

As per the angle sum property, the value of x is 125°

Angle sum property:

According to the angle sum property, the sum of interior angles of a triangle is 180°.

Given,

In the given diagram, PQR and SQT are straight line.

Now we need to find the value of x.

As per the angle sum property, we know that the sum of all the angles of the triangle is 180 degrees.

While we equate the given values within this property, we get.

x° + 55° = 180°

x° = 180° - 55°

x° = 125°

Therefore, the value of x is 125°.

Solving for x, we have

The total amount earned from mowing lawns by George is $50

From the question, we have the following parameters that can be used in our computation:

Earnings percentage = 140%

Angel total earnings in mowing lawns = $70

The amount earned from mowing lawns by George is then calculated as

Angel total earnings in mowing lawns = Earnings percentage  x Total amount earned from mowing lawns by George

Substitute the known values in the above equation

So, we have

70 = 140% x Total amount earned from mowing lawns by George

Divide both sides by 140%

Total amount earned from mowing lawns by George = 50

Hence, the total amount is $50

The outer perimeter of the no-slip surface is 78 feet if the swimming pool has a 3-ft-wide no-slip surface around it.

The outer perimeter of an area or land can be described as the whole of its outer edge or can be described as the sum total of the outside edge lengths.

We can find the outer perimeter of this swimming pool by adding 3 feet twice to all the sides of this rectangular swimming pool followed by the addition of these sides together.

As the swimming pool is 12-ft-by-15-ft, this represents that two sides of this rectangular swimming pool are 15 feet and the other two sides are 12 feet, therefore;

12 + 6 = 18

15 + 6 = 21

Now we can find the perimeter by the addition of all the sides as follows;

18 + 18 + 21 + 21 = 78 feet

Therefore, the outer perimeter of the no-slip surface is found to be equal to 78 feet.

The length of the ladder = 3.8 meter

The length of wall = 2.1 meter

Draw the figure using the measurements

We have to use the trigonometric function

The angle that a ladder make with the ground

sin θ = Opposite side / Hypotenuse

sin θ = 2.1/3.8

θ = 33.54 degrees

The distance from the foot of the ladder from the wall

cos θ = Adjacent side / Hypotenuse

cos 33.54 = Adjacent side / 3.8

Adjacent side = 3.8 × cos 33.54

The probability that the score of a randomly selected examinee is less than 370 is 0.113

Mean of the gmat score = 410

Standard deviation of the deviation = 33

The randomly selected examinee be X ,

Thus X = 370

So , we need to find the probability that the score of a randomly selected examinee is less than 370 i.e.

   P(X < 370)

Now , let us the z-score with normal distribution formula

        Z = (X - μ) / σ

        Z = (370 - 410) / 33

        Z = -40 / 33

       Z = -1.21

Thus P(X < 370) = P(Z < -1.21)

From the z - table , we can get that

         P(Z < -1.21) = 0.11314

By rounding off to three decimals ,

          P(Z < -1.21) = 0.113

Therefore , the probability of Z< -1.21 is 0.113

Step-by-step explanation:

Based on the amount of the loan, and the number of periods as well as the APR, the total amount of the monthly payment would be $6,423.

The monthly payments for the loan would be constant so they can be considered to be annuities.

The value of these annuities would be:

Present value of annuity = Annuity x ( 1 - (1 + rate)^-number of periods) / rate

6,100 = Annuity x (1 - (1 + 5%/12)⁻⁽²ˣ¹²⁾ / 0.05/12)

Annuity = 6,100 / 22.793898393955992921598741250451

Let jeans be x

Let shirts be y

3x + 7y = 60.... eq 1

2x + 3y = 30...... eq 2

Let us make x the subject formula from equation 2

2x = 30-3y

x= (30-3y)/2..... eq 3

Put the value of x into equation 1

3 * (30-3y)/2 + 7y = 60

(90- 9y)/2 + 7y = 60

45 - 4.5y + 7y = 60

The exact value of cos(A - B) is -2√5 /25.

Therefore,

sin A = 0.3

sin B = (1/√5)

cos A = 0.7

cos B = (-1/√5)

cos(A-B) = cos a cos b + sin a sin b

⇒ cos(A-B) = 0.7(-1/√5) + 0.3((1/√5))

⇒ cos(A-B) = -0.7/√5 + 0.3/√5

⇒ cos(A-B) = -0.4/√5

The amount to be paid after paying interest of 7% for 10 years is 10,2000

The amount to be borrowed from the bank = 6000

Interest rate for the amount per year = 7%

The total time period of the loan = 10 years

Thus , the final amount can be calculated by using the formula

                    A = P(1 + rt)

where A is the final amount

          P is the principal amount to be borrowed

          r is the rate of interest

          t is the time period

Now, let us substitute the known values in the above equation , we get

             A = 6000 ( 1 + 0.07 x 10)

                 = 6000 (1 + 0.7)

                 = 6000 (1.7)
