Answer:
The flat charge
Step-by-step explanation:
The number 2 could represent the flat charge in the equation because a flat charge never changes. In the equation, the 2 (y-intercept) is the only term that does not change. The value of 2.8x depends on what the value of x is, and the value of y depends on what the value of 2.8x + 2 is. Therefore, 2 could represent the flat charge in the equation.

Solve the rational equation:
4x/x+5 = x/x+4
Answer:
[tex] x = 0 [/tex] or [tex] x = -\dfrac{11}{3} [/tex]
Step-by-step explanation:
I assume the denominators are x + 5 and x + 4 although that is not what you wrote.
[tex] \dfrac{4x}{x+5} = \dfrac{x}{x+4} [/tex]
[tex] (x + 4)(x + 5)\times \dfrac{4x}{x+5} = (x + 4)(x + 5) \times \dfrac{x}{x+4} [/tex]
[tex] (x + 4)(4x) = (x + 5)(x) [/tex]
[tex] 4x^2 + 16x = x^2 + 5x [/tex]
[tex] 3x^2 + 11x = 0 [/tex]
[tex] x(3x + 11) = 0 [/tex]
[tex] x = 0 [/tex] or [tex] 3x + 11 = 0 [/tex]
[tex] x = 0 [/tex] or [tex] 3x = -11 [/tex]
[tex] x = 0 [/tex] or [tex] x = -\dfrac{11}{3} [/tex]

The measure of center that would best describe a typical value of the data set is a mean since the values are close.
What is a measure of center?It should be noted that the measure of center include the mean, median, mode, and the mid-range.
In this case, when there is a close distribution of different numbers, he beta measurement will be the mean.
Therefore, the mean of the numbers will be:

to get the slope of any straight line, we simply need two points off of it, hmm from the table let's use hmmm (2 , 0) and (4 , -2)
[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-2}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-2}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{2}}}\implies \cfrac{-2}{2}\implies -1[/tex]
Step-by-step explanation:
To find the slope, take 2 points from the graph. I'm going to pick (0,2) and (1,1). Whenever we find the slope this way, we need to keep this formula in mind:
[tex] \frac{y2 - y1}{x2 - x1} = slope[/tex]
So, in this case, we need to do this:
[tex] \frac{1 - 2}{1 - 0} = \frac{ - 1}{1} [/tex]

the width of a rectangle is 3x+1. the length is three times the width. what is the simplified expression of the total perimeter of this rectangle?
Answer:
The total perimeter here is P =21x + 7
Step-by-step explanation:
Let W and L represent the width and length of the rectangle. Then the perimeter is P = 2W + 2L. Substituting 3x + 1 for W and 3(3x + 1) for L, we get
P = 2(3x + 1) + 2*3*(3x + 1), or P = 7(3x + 1) = P =21x + 7

A cup has the shape of a right circular cone. The height of the cup is 16 cm, and the radius of the
cm opening is 4 cm. Water is being poured into the cup at a constant rate of 3 cm. At what rate, in
cm per second, is the water level rising when the depth of the water in the cup is 6 cm? (The volume of a cone of height h and radius r is given by V=1/3pir^2h.
1. 1/64pi
2. 3/pi
3. 4/3pi
4. 9/4pi
Answer:
3. [tex]\dfrac{4}{3 \pi}[/tex]
Step-by-step explanation:
Volume of a cone:
[tex]V=\dfrac13\pi r^2h[/tex]
(where r is the radius and h is the height)
Given:
h = 16 cmr = 4 cm[tex]\implies r=\dfrac14h[/tex]
Therefore, substitute [tex]r=\frac14h[/tex] into the volume formula to find the volume of the cone in terms of h:
[tex]\implies V=\dfrac13\pi \left(\dfrac14h\right)^2h[/tex]
[tex]\implies V=\dfrac{1}{48}\pi h^3[/tex]
Differentiate with respect to h:
[tex]\implies \dfrac{dV}{dh}=3 \cdot \dfrac{1}{48} \pi h^2=\dfrac{\pi h^2}{16}[/tex]
Volume is increasing at a constant rate of 3cm/s:
[tex]\implies \dfrac{dV}{dt}=3[/tex]
Use the chain rule to find [tex]\dfrac{dh}{dt}[/tex]
[tex]\implies \dfrac{dh}{dt}=\dfrac{dV}{dt}\times\dfrac{dh}{dV}[/tex]
[tex]\implies \dfrac{dh}{dt}=3\times\dfrac{16}{\pi h^2}[/tex]
[tex]\implies \dfrac{dh}{dt}=\dfrac{48}{\pi h^2}[/tex]
When h = 6:
[tex]\implies \dfrac{dh}{dt}=\dfrac{48}{\pi \cdot 6^2}=\dfrac{4}{3 \pi}[/tex]

Step-by-step explanation:
The answer is 104 1/2 since the formula for volume is LWH. You have to do 6 1/3*3*5 1/2.
6 1/3=19/3
5 1/2=11/2
19/3*3/1=57/3.
57/3*11/2=627/6.
627/6=104.5 or 104 1/2.

The length of segment YT will be equal to 12 units as the line segment XY is dilated to create line segment X'Y' using point t as the center of dilation.
What is dilation?Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

Step-by-step explanation:
-12x-7=53
+7=+7
-12x=60
divide both sides by negative 12
60/-12= -5
so x =-5
The solution of the linear equation with a single variable - 12x - 7 = 53 will be -5.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The equation with a single variable 'x' is given below.
- 12x - 7 = 53
Simplify the equation, then we have
- 12x - 7 = 53
- 12x = 60
x = 60 / (-12)
x = - 5
The solution of the linear equation with a single variable - 12x - 7 = 53 will be -5.
