Factor the trinomial.
x^2-4x-5

Answer:

x = 8

Step-by-step explanation:

Since the triangle is equilateral, then the 3 sides are congruent.

Equate any 2 sides and solve for x, that is

7x - 29 = 5x - 13 ( subtract 5x from both sides )

2x - 29 = - 13 ( add 29 to both sides )

2x = 16 ( divide both sides by 2 )

x = 8

The triangle is equilateral, thus the 3 angles are congruent, thus

The measure of each angle is 60°

The value of the variable 'x' will be 8. And the measure of each angle will be 60°.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

If triangle ΔGHJ is an equilateral triangle.

GH = 5x - 13, HJ = 11x - 61, and GJ = 7x - 29

In the equilateral triangle, all the sides of the equilateral triangle are equal and each angle of the equilateral triangle will be 60 degrees.

GH = HJ = GJ

From the first two-term, then the value of the variable 'x' will be calculated as,

GH = HJ

5x - 13 = 11x - 61

11x - 5x = 61 - 13

6x = 48

x = 8

The value of the variable 'x' will be 8. And the measure of each angle will be 60°.

We want to create and study a function that models the given situation.

We will find that the correct option is:

"The values of both x and y will be real numbers greater than or equal to 0."

The information that we have is:

Peaches are being sold for $2 per lb.

Then if we define x as the number of pounds that you buy, and y as the cost of these peaches, we can write the function:

y = $2*x

Now we want to see which statement describes the values of x and y.

Let's analyze each statement:

1) "The values of both x and y can be any real number."

False, a real number is -3, and you can't buy a negative number of peaches.

2) "The values of both x and y will be real numbers greater than or equal to 0."

Here we removed the above problem, so this works fine.

3) "The value of x and y will always be zero"

No, you can buy 2 pounds of peaches and you will pay:

y = $2*2 = $4

So neither x nor y need to be zero.

4) The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

Here we do not have problems, but there are some cases where the cost could be a fraction, like if you buy 0.25 lb of peaches:

y = $2*0.25 = $0.5

So the cost does not need to be an integer.

Finally, we can see that the correct option is:

"The values of both x and y will be real numbers greater than or equal to 0."

It 5 would not be x

Step-by-step explanation:

If 5 was x, then it would be equivalent, because 5+3 = 8. I hope this helped.

The solution is x > 5 of the set of x+3 > 8.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

Here 5 is no solution to the given problem because there is no sign of equality.

Due to the fact that 5+3 = 8, if 5 were x, it would be equivalent.

We have to determine the solution set of x+3 > 8

Given inequality as

⇒ x + 3 > 8

Subtract 3 from both sides of the inequality,

⇒ x + 3 - 3 > 8 - 3

⇒ x > 5

Therefore, the solution is x > 5 of the set of x+3 > 8.

Answer:

Table (4)

Step-by-step explanation:

Slope of a line passing through  two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the table (1),

Two points lying on the graph are (2, 1) and (6, -1).

Slope of the line = [tex]\frac{1+1}{2-6}[/tex] = [tex]-\frac{1}{2}[/tex]

From the table (2),

Two points lying on the linear function are (0, 8) and (2, 4).

Slope of the line =  [tex]\frac{8-4}{0-2}[/tex] = -2

From the table (3),

Two points are (-4, 4) and (-2, 5).

Slope of the line = [tex]\frac{5-4}{-2+4}[/tex] = [tex]\frac{1}{2}[/tex]

From table (4),

Two points lying on the function are (-2, 0) and (0, 4).

Slope of the line = [tex]\frac{4-0}{0+2}=2[/tex]

Therefore, Table (4) represents a linear function with slope 2.

Step-by-step explanation:

The equation of the number of students needed to make $1,500 in profit will be 1,500 = 5n – 300. Then the correct option is A.

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

Mustafa's soccer team is planning a school dance as a fundraiser.

The DJ charges $200 and decorations cost $100.

The team decides to charge each student $5.00 to attend the dance.

If n represents the number of students attending the dance.

The total amount of expenses will be

Total Expense = $200 + $100

Total Expense = $300

The total amount of charges will be

Total Charge = 5n

Then the amount of the profit will be

Profit = Total charge – Total expense

1,500 = 5n – 300

Then the equation can be used to find the number of students needed to make $1,500 in profit will be 1,500 = 5n – 300.

Then the correct option is A.

Answer: (1,2)

Step-by-step explanation: In order to get 3/4 the distance, you have to use midpoint formula. Use midpoint formula to get the midpoint between M and N. In this case it would be the square root of ((x1+x2/2),(y1+y2/2)) (you can google this if it is not clear because of formatting). Once you get the midpoint of M and N, should be (-1,4) and we will call this point Z for reference, you find the midpoint of the original midpoint (point Z aka (-1,4) in our case) and point N. In doing this, your math should come out to the new point that is 3/4 to the distance. This point should be (1,2) if I am not mistaking.

Answer:

Around $4,368

Step-by-step explanation:

The initial cost is $11,800.

Each year, the new value will be 22% less than the previous year. Meaning that for each year that passes, the initial value will be multiplied by 0.78:

22% = 0.22

1 - 0.22 = 0.78

The value of the car after 4 years can thus be expressed as:

[tex]11800 * 0.78 * 0.78 * 0.78 * 0.78[/tex]

Or:

[tex]11800 * 0.78^4[/tex]

693.1

Step-by-step explanation:

(1.2 x 105) +(5.35 x 106)

1. 1.2 x 105=126

2. 5.35 x 106=567.1

Your answer is 693.1.

Remove unneeded parentheses from both equations.

That will give us the following...

1.2 x 105 + 5.35 x 106

So now lets solve 1.2 x 105.

1.2 x 105=126

Next, lets solve 5.35 x 106.

5.35 x 106= 567.1
