Explain why ABCD and ABEC are parallelograms.

Answer: B

Step-by-step explanation:

The line is curved which makes it a non-linear function.

Answer:

x>2

Step-by-step explanation:

Answer:   [tex]x \ge 2[/tex]

The x part is already taken care of, so you'll fill the rest into the box.

On a keyboard you could type x >= 2 to mean [tex]x \ge 2[/tex]

=====================================================

Explanation:

We have a closed or filled in circle at x = 2. This means 2 is included in the shaded region solution set. So we'll have "or equal to" as part of the inequality.

We'll also have "greater than" because how the shading is to the right of the closed circle.

So put together that's why the graph represents [tex]x \ge 2[/tex]

Something like x = 5 is a solution because [tex]5 \ge 2[/tex] is true

Something like x = 0 is not a solution because [tex]0 \ge 2[/tex] is false

Answer:

-1/2 or no solution (depends on what the teacher is asking)

Step-by-step explanation:

2x*2 - 4x = 2

combine like terms

-2x*2=2

divide by 2

-2x=1

divide by -2

x= -1/2

Answer:

No it's not, because a square has all the sides equal, but this hasn't, therefore it's not a square

A slope is also known as the gradient of a line. The slope of the line is 7/2.

A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

The two of the points that lie on the line are (0,0) and (4,14). Therefore,

The slope of the line is,

Slope, m = (14-0)/(4-0) = 14/4 = 7/2

Hence, the slope of the line is 7/2.

Step-by-step explanation:

The answer is a complex fraction division. The easiest way to do it is likely to convert both fractions to a decimal.

3/4 = 0.75

$112.80

Step-by-step explanation:

You are buying 8 student tickets, each costing $10.68. Multiply 8 with 10.68:

10.68 x 8 = 85.44

You are buying another 2 adult tickets, each costing $13.68. Multiply 2 with 13.68:

13.68 x 2 = 27.36

Next, add the two costs together:

27.36 + 85.44 = 112.80

$112.80 is your total cost.

Answer: (x - 1)(x + 1)^2(x - 4)^3

Step-by-step explanation:

First, remember that:

in expressions like: (x - b)^n

b is the value of x where the graph intersects the x-axis.

n can represent:

n = 1, the line just goes through the x-axis

n = 2, the line may change the direction (an inflection point), and touch the x-axis in one point.

n = 3, the line may have two inflection points when it intersects the x-axis.

Then we have the expression:

(x-b)(x-c)^2(x-d)^3

b is in the linear part, the graph crosses the x-axis linearly in x = 1.

c is in the quadratic part, the graph crosses the x-axis with one point of inflection at x = -1.

d is in the cubic part, the graph crosses the x-axis with two inflections in x = 4.

Then we can writhe the polynomial as:

f(x) = (x-1)(x-(-1))^2(x-4)^3 = (x - 1)(x + 1)^2(x - 4)^3

Answer:

(x - 1)(x + 1)^2(x - 4)^3

Answer:

The quadratic equation is y = - (x - 5)² + 12

Step-by-step explanation:

The vertex form of the quadratic function is

y = a(x - h)² + k, where

In the question

∵ The graph is open downward

∴ a < 0 (a is a negative number)

∵ The vertex point is (5, 12)

∴ h = 5 and k = 12

Substitute them in the form of the equation

∴ y = a(x - 5)² + 12

→ To find a you must have a point on the graph of it to substitute

   x and y by its coordinates. because we don't have a point on

   the graph we can choose a any negative number.

∵ a is a negative number, let us choose it -1

∴ y = - (x - 5)² + 12

The quadratic equation is y = - (x - 5)² + k

Answer:

The value of u is 6

Step-by-step explanation:

The rule of the slope of a line is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] , where

[tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] are two points on the line

Let us use this rule to solve the question

∵ The slope of the line is -3

∴ m = -3

∵ The two points on the line are (-5, u) and (-4, 3)

∴ [tex]x_{1}[/tex] = -5 and [tex]x_{2}[/tex] = -4

∴ [tex]y_{1}[/tex] = u and [tex]y_{2}[/tex] = 3

→ Substitute these values in the rule of the slope above

∴ [tex]-3=\frac{3-u}{-4-(-5)}[/tex]

∴ [tex]-3=\frac{3-u}{1}[/tex]

→ By using cross multiplication

∴ -3 × 1 = 3 - u

∴ -3 = 3 - u

→ Add u to both sides to move u from the right side to the left side

∴ -3 + u = 3 - u + u

∴ -3 + u = 3

→ Add 3 to both sides to move -3 from the left side to the right side

∴ -3 + 3 + u = 3 + 3

∴ u = 6

The value of u is 6
