Answer:
Step-by-step explanation:
Both expression are the same :
14 = 2(x + 3)
By expansion :
14 = 2*x + 2*3
14 = 2x + 6
Hence ;
Both expression are the same
Weight of one circle :
Final weight on both sides are equal:
Weight on Left hand side = 14
Weight on right hand side = 3*x + 3*x
Weight on Left hand side = Weight on right hand side
14 = 3x + 3x
14 = 6x
x = 14 / 6
x = 2.333

What is the graph for if y is a function of x
Answers
Answer:
The y value of a point where a vertical line intersects a graph represents an output for that input x value. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output.

If n is a positive integer, how many 5-tuples of integers from 1 through n can be formed in which the elements of the 5-tuple are written in increasing order but are not necessarily distinct? In other words, how many 5-tuples of integers (h, i, j, k, m) are there with 1 ≤ h ≤ i ≤ j ≤ k ≤ m ≤ n? As in Example 9.6.3, you can represent any ordered 5-tuple of integers (h, i, j, k, m) with 1 ≤ h ≤ i ≤ j ≤ k ≤ m ≤ n as a string of n − 1 vertical bars and 5 crosses, with the position of crosses indicating which 5 integers from 1 to n are included in the 5-tuple. Thus, the number of 5-tuples is the same as the number of strings of n+4 vertical bars and 5 crosses, which is n(n+1)(n+2)(n+3)(n+4) 120 .
Answers
Answer:
[tex]\frac{(n+4)*(n+3)*(n+2)*(n+1)*n}{120}[/tex]
Step-by-step explanation:
Given
5 tuples implies that:
[tex]n = 5[/tex]
[tex](h,i,j,k,m)[/tex] implies that:
[tex]r = 5[/tex]
Required
How many 5-tuples of integers [tex](h, i, j, k,m)[/tex] are there such that[tex]n\ge h\ge i\ge j\ge k\ge m\ge 1[/tex]
From the question, the order of the integers h, i, j, k and m does not matter. This implies that, we make use of combination to solve this problem.
Also considering that repetition is allowed: This implies that, a number can be repeated in more than 1 location
So, there are n + 4 items to make selection from
The selection becomes:
[tex]^{n}C_r => ^{n + 4}C_5[/tex]
[tex]^{n + 4}C_5 = \frac{(n+4)!}{(n+4-5)!5!}[/tex]
[tex]^{n + 4}C_5 = \frac{(n+4)!}{(n-1)!5!}[/tex]
Expand the numerator
[tex]^{n + 4}C_5 = \frac{(n+4)!(n+3)*(n+2)*(n+1)*n*(n-1)!}{(n-1)!5!}[/tex]
[tex]^{n + 4}C_5 = \frac{(n+4)*(n+3)*(n+2)*(n+1)*n}{5!}[/tex]
[tex]^{n + 4}C_5 = \frac{(n+4)*(n+3)*(n+2)*(n+1)*n}{5*4*3*2*1}[/tex]
[tex]^{n + 4}C_5 = \frac{(n+4)*(n+3)*(n+2)*(n+1)*n}{120}[/tex]

A line passes through the point (2, -9) and has a slope of -9. Write an equation in point-slope form for this line.
Answers
Answer:
[tex] y+9 = - 9x +18[/tex]
Step-by-step explanation:
Line is passing through the point [tex] (2,\: - 9) =(x_1,\:y_1) [/tex] and has slope (m) = - 9
General equation of line in point slope form is given as:
[tex] y-y_1 = m(x-x_1)[/tex]
Therefore
[tex] y-(-9) = - 9(x-2)[/tex]
[tex] y+9 = - 9x +18[/tex]
This is the required equation of line in point slope form.

When an amount of heat Q (in kcal) is added to a unit mass (kg) of a
substance, the temperature rises by an amount T (°C). The quantity dQ/dT, called
specific heat, is 0.18 (kcal/°C) for glass. If dQ/dt = 12.9 kcal/min for a 1 kg sample
of glass at 20.0 °C, find dT/dt for this same sample. (Note: T is for temperature, t is
for time.)
Answers
Answer:
The change in temperature per minute for the sample, dT/dt is 71.[tex]\overline {6}[/tex] °C/min
Step-by-step explanation:
The given parameters of the question are;
The specific heat capacity for glass, dQ/dT = 0.18 (kcal/°C)
The heat transfer rate for 1 kg of glass at 20.0 °C, dQ/dt = 12.9 kcal/min
Given that both dQ/dT and dQ/dt are known, we have;
[tex]\dfrac{dQ}{dT} = 0.18 \, (kcal/ ^{\circ} C)[/tex]
[tex]\dfrac{dQ}{dt} = 12.9 \, (kcal/ min)[/tex]
Therefore, we get;
[tex]\dfrac{\dfrac{dQ}{dt} }{\dfrac{dQ}{dT} } = {\dfrac{dQ}{dt} } \times \dfrac{dT}{dQ} = \dfrac{dT}{dt}[/tex]
[tex]\dfrac{dT}{dt} = \dfrac{\dfrac{dQ}{dt} }{\dfrac{dQ}{dT} } = \dfrac{12.9 \, kcal / min }{0.18 \, kcal/ ^{\circ} C } = 71.\overline 6 \, ^{\circ } C/min[/tex]
For the sample, we have the change in temperature per minute, dT/dt, presented as follows;
[tex]\dfrac{dT}{dt} = 71.\overline 6 \, ^{\circ } C/min[/tex]
PLEASE HELP IM GIVING 100 POINTS AND BRAINLIEST IF THE ANSWERS RIGHT
A six-sided number cube labeled 1 through 6 is rolled 600 times. An odd number is rolled 272 times. Compare the experimental probability of rolling an odd number with the relative frequency of rolling an odd number and select one of the statements below that best describes the situation. (5 points)
a
The experimental probability and relative frequency are the same.
b
The experimental probability is larger than the relative frequency.
c
The experiment probability is smaller than the relative frequency.
d
There is not enough information to determine the relative frequency.
Answers
Answer:
Relative frequency is defined as the number of "desired" results divided by the total number of possible results. Experimental probability is defined the same way. This means that the first choice is best, the experimental probability and relative frequency are the same.
The theoretical probability, on the other hand, would be 0.5, or 300/600, which is larger than the experimental probability.

Step-by-step explanation:
You can figure out the answer to this problem by going through the steps in your head. You can tell the answer is C because if you flip the quadrilateral ABCD over the x-axis and then imagine rotating it around the origin by 180°, it would end up where A'B'C'D' is. If you can't imagine this, you can go onto a graphing calculator like desmos and do the transformations to see if they work.

A scalene triangle has no similarities between the angles or the sides
In the shown triangle none of the sides are similar and none of the angles are congruent therefore this is a scalene triangle
Reasons why its not the other answers
This is not an acute triangle. In order for it to be an acute triangle all of the angles have to have a measure less than 90 degrees. There is an angle with a measure of 120 degrees the triangle is not an acute triangleThis triangle is not an isosceles triangle. In order for it to be an isosceles triangles it has to have at least one congruent side. None of the sides are congruent therefore it is not an isosceles triangleThis is not a right triangle. In order for it to be a right triangle one of the angles has to have a measure of 90 degrees. Because none of the angles measure 90 degrees it is not a right triangleIn conclusion the answer would be that this triangle is a scalene triangle
Answer:
it is a scalene triangle
Step-by-step explanation:
it is not an acute triangle because 120° + 20° +40° = 180° not 90°.
it is not an isosceles triangle because no 2 sides are the same length.
it is not a right triangle because no sides are perpendicular (there is no 90° angle)
and it is scalene because all lengths of the triangle are different.
