The zeros of the factored form of the equation is x = 1, 5, and -7.

Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form. Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities.

We have been given the factored equation as; y=(x−1)(x−5)(x+7) that has zeros (or x-intercepts).

y=(x−1)(x−5)(x+7)

then the roots of the equation;

For (x−1)

x - 1 = 0

x = 1

For (x−5)

x - 5 = 0

x = 5

For (x+ 7)

x + 7 = 0

x = -7

Hence, The zeros of the factored form of the equation is x = 1, 5, and -7.

9 units to the right and 5 units down

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 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.

Step-by-step explanation:

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

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]

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

Let the four consecutive integers in the question be;

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

P(White)=50/200=0.25

Answer:  The correct answer is B. There is a linear relationship between the number of costumes and fabric. The rate of change is 3.5 yards per costume.

Step-by-step explanation:

Divide the Fabric yards by the number of costumes:

7 / 2 = 3.5

14 / 4 = 3.5

21 / 6 = 3.5

28 / 8 = 3.5

Since they are all 3.5 yards per costume, the relationship is LINEAR

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.

In this question, we have been given a piggy bank contains 2.65$ in nickels and dimes. Then There are 29 nickels and 12 dimes in the piggy bank.

We need to find the number of nickels and dimes if the number of nickels is 7 less than three times the number of dimes.

Let x be the number of nickels and y be the number of dimes.

We know that, 1 dollar = 20 nickels

and 1 dollar = 10 dimes

So, we get an equation

0.05x + 0.1y = 2.65                   ...........(1)

Also the number of nickels is 7 less than three times the number of dimes.

x = 3y - 7                      .................(2)

Substitute above value of x in equation (1)

0.05(3y - 7) + (0.1)y = 2.65

0.15y - 0.35 + 0.1y = 2.65

0.25y = 2.65 + 0.35

0.25 y = 3

y = 12

Substitute above value of y in equation  (2)

x = 3(12) - 7

x = 29

Therefore, there are 29 nickels and 12 dimes in the piggy bank.

length × width

in our case

(x + 10) × x = 50

x² + 10x = 50

x² + 10x - 50 = 0

the general solution to such a quadratic equation

ax² + bx + c = 0

is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case that is

x = (-10 ± sqrt(10² - 4×1×-50))/(2×1) =

= (-10 ± sqrt(100 + 200))/2 =

= (-10 ± sqrt(300))/2 = (-10 ± sqrt(100×3))/2 =

x1 = -5 + 5×sqrt(3) = 3.660254038...

x2 = -5 - 5×sqrt(3) = -13.66025404...

Width of the rectangle is 2.5, Length is 10 and perimeter is 25

Given

Length of rectangle is 5 greater than double of width

let us say width = w

According to the question length L = 5 + 2w

Perimeter is 10 times the width

P= 10w

we know that perimeter of a rectangle is 2(L+W)

Substituting the values in the formula we get

10w = 2(5+2w + w)

10w = 10 + 6w

w= 2.5

From this length L = 5+2(2.5)

                            L = 10

Perimeter P = 10W

P= 10(2.5)

P= 25

Hence the length is 10, width is 2.5 and perimeter is 25
