The perimeter of the rectangular tennis court is 96.7 m

An equation shows the relationship between two or more numbers and variables.

Let x represent the length and y represent the width. A rectangular tennis court has an area of 528 m², hence:

Area = length * width

528 = xy

y = 528/x

If the length is decreased by 1 m and the width is increased by 1 m, the area of the tennis court is increased by 16 m². Hence:

new area = new length * new width

528 + 16 = (x - 1)(y + 1)

xy + x - y + 1 = 544

x(528/x) + x - 528/x + 1 = 544

528 + x - 528/x + 1 = 544

multiplying through by x:

528x + x² - 528 + x = 544x

x² -15x - 528 = 0

x = 31.67, hence y = 528/31.67 = 16.67

Perimeter = 2(x + y) = 2(31.67 + 16.67)

Perimeter = 96.7 m

The perimeter is 96.7 m

The time period in years T = 4 years

The simple interest amount = $252

The rate of interest per year as percentage  = 7%

The principal amount = $900

The simple interest I = PTR

Where I is the interest amount

P is the principal Amount

T is the time period involved in years

R is the rate of interest per year as a percent

Substitute the values in the equation

252 = 900 × T × (7 / 100)

252 = 900 × T × 0.07

252 = 63 × T

Move the 63 to other side

T = 252 / 63

T = 4 years

Hence, the time period in years T = 4 years

The general form of equation a) y = 2, b) x = -4.

Here the point A = (-4,2)

a) we have to find the equation parallel to the x-axis

As a line should be parallel to x axis so it must pass from y-axis. As the coordinate of A is (-4, 2) so by this we get y = 2 and x = -4.

But we have to put the value of x as 0 and y = 2 then only we get an equation of a line parallel to x-axis.

So y = 2

which is parallel to x-axis

b) equation of a line perpendicular to the x-axis.

As a line should be perpendicular to x-axis, so line should pass form the x-axis and not with the y-axis. As point A is (-4. 2), so we have to take the value of x = -4 and y = 0. So we get an equation.

x = -4 is the general equation.

Therefore the general equation a) y =2 and b) x =-4.

The option for 6-pack of student tickets will be of lesser cost than that of individual cost.

Multiplication is a way of finding the product of two or more numbers. It is one of the basic mathematical operations, that we use in our day to day life.

Given, total number of students= 6

Cost of individual student ticket= $21.50

Therefore, total cost of buying tickets to an adventure day= $(6×21.5)= $129.00

Now, cost of 6-pack of student tickets= $126.00

Thus by comparing the two costs, we can see that the lesser option between the two is the 6-pack of student tickets by $(129-126)= $3

The number of tacos sold in August, September and October is 103, 206, 618 respectively.

Let the number of veggie tacos sold by Tina in October be x

Then, number of veggie tacos sold in September is twice that of veggie tacos sold in october = 2x

Number of veggie tacos sold in August is thrice that of veggie tacos sold in September = 3 x 2x = 6x

Total veggie taco during the three months by Tina = 927

6x + 2x + x = 927

9x = 927

x = 927/9

x = 103

Tacos sold in August = 6x =  618

Tacos sold in September = 2x = 206

Tacos sold in October = x =103

Therefore, the number of tacos sold in August, September and October is 103, 206, 618 respectively.

Based on the given figures, the line of reflection will be c. Reflection across x-axis.

If it looks like the line of reflection is a horizontal line as is the case here, the way to find the line of reflection is by finding the midway point between corresponding points on the graph.

For instance, use the coordinates of D and D' and C and C'.

The coordinates of D and D' are:

D = (-1, 1)

D' = (- 1, -1)

The Midpoint can be found to be:

= ( (x₁ + x₂) / 2, (y₁ + y₂) / 2)

= ( (-1 + (-1)) / 2), ( (1 + (-1)) / 2

= (-1, 0)

The coordinates of C and C' are:

C = (4, 1)

C' = (4, -1)

The Midpoint can be found to be:

= ( (x₁ + x₂) / 2, (y₁ + y₂) / 2)

= ( (4 + 4) / 2), ( (1 - (-1)) / 2

= (4, 0)

The line of reflection is therefore the x-axis because the value of y is 0 and the x = axis is the line that crosses y at 0.

Answer: p= -5

Step-by-step explanation:

Answer:

-5

Step-by-step explanation:

carry the one over to the right side and subtract it to get an amount of -10.

then carry the -4p to the left and add it with -2p. which comes out to be 2p

now the equation reads as 2p=-10

continue to divide 2 to get p alone and divide -10 by 2 as well.

now p=-5 because a negative divided by a postive is a negative.

Equation of a line in the standard form that passes through the points (3, 0) and (0, -2) will be [y = (2/3)x - 2].

As per the question statement, a straight line passes through the points (3, 0) and (0, -2).

We are required to determine the equation of the above mentioned line in it's standard form.

To solve this question, we need to know the formula to write the standard equation of a line passing through two points (x₁, y₁) and (x₂, y₂) which goes as [tex][(y-y_{1})=\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}(x-x_{1})][/tex].

Here, let (x₁, y₁) be (3, 0) and (x₂, y₂) be (0, -2).

Therefore, equation of our concerned line passing through the two points (3, 0) and (0, -2), by substituting [(x₁, y₁) = (3, 0)] and [(x₂, y₂) = (0, -2)] in the above mentioned formula, will be [(y - 0) = {(-2 - 0)/0₂ - 3)}(x - 3)]

Or, [y = {(-2)/(-3)}(x -3)]

Or, [y = (2/3)(x - 3)]

Or, [y = (2/3)x - 2]

x² + 10x - 50 = 0

the general solution to such a quadratic equation

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case that is

Answer:

ΔABC ≅ ΔNKW because when ΔABC is translated 9 units right and 5 units down, it results in the other triangle.

Step-by-step explanation:

The triangles are congruent as the measures of their corresponding sides and angles are the same.

To determine the translation of ΔABC to ΔNKW, find the change in the x and y values from one of the points of ΔABC to its corresponding point of ΔNKW.

Therefore:

ΔABC ≅ ΔNKW because when ΔABC is translated 9 units right and 5 units down, it results in the other triangle.

The four consecutive integers in the question are; 51, 52, 53, 54

Let the four consecutive integers in the question be;

x, x + 1, x + 2 and 2(x + 4)

Now, we are told that the sum of these four consecutive integers is 264. Thus;

x + x + 1 + x + 2 + 2(x + 3) = 264

Expanding the bracket gives;

3x + 3 + 2x + 6 = 264

5x + 9 = 264

5x = 264 - 9

5x = 255

x = 255/5
