What is the value of x?
Enter your answer, as a decimal, in the box.
x=
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:
4.2

To solve this problem, we need to use our order of operations, or PEMDAS.
Parenthesis
Exponent
Multiply
Divide
Add
Subtract
6÷2(1+2) [parenthesis]
6÷2(3) [multiply/divide from left to right]

Jordan throws a ball from a cliff 12 feet above the ground with an initial velocity of 32 feet per second. In the following functions, h(t) represents the height of the ball above the ground, in feet, with respect to time, t, in seconds, after the ball was thrown. Which of the following functions models the amount of time the ball is in the air?
h(t)= -4(t-1)^2 +3
h(t)= -16(t-1)^2 -4
h(t)= -16(t-1)^2 +12
h(t)= -16(t-1)^2 +28
Answer:
Your answer will be the third function
Step-by-step explanation:
The base function you need to know is h(t)= 1/2at^2
Your acceleration in this problem is going to be gravity which they give to you, 32 feet per second squared. Since the ball is falling, it means it will have negative acceleration. Now you have the equation h(t)= -16t^2. The final step is to add the initial height from which the ball was dropped giving you: h(t)= -16t^2 +12

Consider the following graph which represents the solutions to a system of inequalities. Which of the following systems of inequalities does the graph represent?
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
m is the slopeb is the y-interceptThe line passes through the origin, then
The value of b = 0The form of the equation is y = m xLet 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

The answer to the different" question is
The answer to the same three questions is
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:
x = 3 - 2 = 4 - 3 = 5 -4 = 1The difference in the term for the y-coordinate is given as:
x = 13 - 10 = 16 - 13 = 19 -16 = 3Hence the difference between the consecutive term of the sequence is (1, 3)

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) :)

i need help with this slope problem
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... :)

Jane is selling handmade hair bows for $5.25 each. A woman came by to buy some for the girls in her daughter's girl scout troop. She spent $84. How many hairbows did she buy?
Answer:
16
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

what is the directrix of a parabola with focus (4,-1) and a vertex at (4,-5)?
Answer:
y = -9Step-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:
[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!

what is P versus NP, its supposed to be one of the hardest questions in the world
Answer:
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.
