Answer:

[tex]x=3.5[/tex]

Step-by-step explanation:

Notice that CD bisects Angle C.

Then by the Angle Bisector Theorem, we can write the following proportion:

[tex]\frac{6}{4.2}=\frac{5}{x}[/tex]

Now, we can solve for x. Cross multiply:

[tex]5(4.2)=6(x)[/tex]

Multiply:

[tex]21=6x[/tex]

Divide both sides by 6:

[tex]x=21/6=7/2=3.5[/tex]

Hence, the vale of x is 3.5.

Answer:

The system of inequalities is -2x + y > 0    -x + y ≥ 0

Step-by-step explanation:

The form of the equation of a line is y = m x + b, where

The line passes through the origin, then

Let us look at the graph to find the correct answer

∵ One of the lines are solid and the other is dashed

∵ The shaded area is over the two lines

∴ The signs of the two inequalities are ≥ and >

∵ The two lines pass through the origin

→ That means the y-intercepts are 0

∴ The form of the inequalities are y ≥ m[tex]_{1}[/tex] x and y > m[tex]_{2}[/tex]

There are only two answers that have these forms, so we must find the slope of each line

∵ m = [tex]\frac{y2-y1}{x2-x1}[/tex] , (x1, y1) and (x2, y2) are two points on the line

∵ The solid line passes through points (0, 0) and (2, 2)

∴ m[tex]_{1}[/tex] = [tex]\frac{2-0}{2-0}[/tex] = [tex]\frac{2}{2}[/tex] = 1

→ Substitute it in the form of the equation

∴ y ≥ 1(x)

∴ y ≥ x

→ Subtract x from both sides

∴ -x + y ≥ 0

∵ The dashed line passes through points (0, 0) and (1, 2)

∴ m[tex]_{2}[/tex] = [tex]\frac{2-0}{1-0}[/tex] = [tex]\frac{2}{1}[/tex] = 2

→ Substitute it in the form of the equation

∴ y > 2(x)

∴ y > 2x

→ Subtract 2x from both sides

∴ -2x + y > 0

The system of inequalities is -2x + y > 0    -x + y ≥ 0

Answer:

The system of inequalities is -2x + y > 0    -x + y ≥ 0

Answer:

[tex]x[/tex] must be number different to 1, 2 and 3 to guarantee that given relation is a function.

Step-by-step explanation:

From Function Theory, we know that a function is a relation in which all domain elements are not related to at least two different elements from range. Which means that [tex]x \in \mathbb{R}-\{1,2,3\}[/tex], that is, that [tex]x[/tex] is a real number different to 1, 2 and 3.

Hence, we conclude that [tex]x[/tex] must be number different to 1, 2 and 3 to guarantee that given relation is a function.

Answer:

It is the first one and the second one. If it is the same, then the slope will be constant.

Step-by-step explanation:

Answer:

I think it's the second one ( Any two points on the line will produce the same slope)

Step-by-step explanation:

Any two points on a line will ALWAYS have the same slope. There's no way that it won't be that way. That's why you are able to choose any two points on a graph to find a slope.

For the first one, i think it's wrong because although the slope is 1/2, Jennifer used the slope 2/4 while Marshall used 1/2. Even though it's the same, Jennifer didn't technically use 1/2...

And the third option is wrong. The slope isn't 2.

Hopefully this wasn't confusing... :)

Answer:

x=40/3 or x=13.3

Step-by-step explanation:

Answer:

The percent change is 60

[tex]60% [/tex]

Answer: 60% increase

Step-by-step explanation:

The slope of the line is 3

The difference between the consecutive term of the sequence is (1, 3)

To get the slope of the graph, we will use the coordinate points (2, 10) and  (3, 13)

Slope = 13-10/3-2

Slope = 3/1

Slope = 3

Hence the slope of the line is 3

The difference in the term for the x-coordinate is given as:

The difference in the term for the y-coordinate is given as:

Hence the difference between the consecutive term of the sequence is (1, 3)

Answer:

Reflections and rotations

Step-by-step explanation:

Reflections and rotations preserves the distance and angle measurements.

Answer:

Step-by-step explanation:

The directrix is at the same distance from the vertex as the focus but on the opposite side of the vertex.

x coordinate the same for a focus and a vertex (4) means the parabola opens up or down and the directrix is parallel to the x-axis.

y coordinate of the focus greater than y coordinate of the vertex means the parabola opens up and the directrix lays below the vertex.

-1-(-5) = - 1 + 5 = 4

so: - 5 - 4 = -9 is the y coordinate of points of the directrix

Answer:

C. [tex] d = \frac{at^2}{2} [/tex]

Step-by-step explanation:

Given:

[tex] t = \sqrt{\frac{2d}{a}} [/tex]

Required:

Make d the subject of the formula.

SOLUTION:

[tex] t = \sqrt{\frac{2d}{a}} [/tex]

Square both sides

[tex] t^2 = (\sqrt{\frac{2d}{a}})^2 [/tex]

[tex] t^2 = \frac{2d}{a} [/tex]

Multiply both sides by a

[tex] a*t^2 = \frac{2d}{a}*a [/tex]

[tex] at^2 = 2d [/tex]

Divide both sides by 2

[tex] \frac{at^2}{2} = \frac{2d}{2} [/tex]

[tex] \frac{at^2}{2} = d [/tex]

[tex] d = \frac{at^2}{2} [/tex]

Step-by-step explanation:

Jane is selling handmade bows at $5.25 each

A woman came and spent $84 buying bows

Therefore the number of bows bought by the woman can be calculated as follows

= 84/5.25

= 16

Hence the woman bought 16 bows

Answer:

[tex]4p+3[/tex]

Step-by-step explanation:

All this question is asking you to do is simplify the given expression by combining like terms.

The point of combining like terms is that you can only combine, well, like terms. Like terms are terms that have the same variables and are raised to the same power. This means that in this case, we can't combine [tex]4[/tex] and [tex]6[/tex] because [tex]4[/tex] is attached to a variable. However, we can combine 6 and -3 because they are like terms; neither is attached to a variable. So, you end up with [tex]4p+3[/tex].

I hope this helps!

P is the set of problems whose solution times are proportional to polynomials involving N's. ... NP (which stands for nondeterministic polynomial time) is the set of problems whose solutions can be verified in polynomial time. But as far as anyone can tell, many of those problems take exponential time to solve.

Answer:

x=30

Step-by-step explanation: First we would have to find the two angles of the corner of the triangle. 55° in the bottom left because of verticle angles. And 180-120= 60. And 60+55=115. 180-115=65. 65-5= 60. 60/2= 30. So x=30. (Sorry ik its sloppy) :)
