1. Find the value of each side.
5x - 3
4x + 6
Answer:
5x-3= 2x
4x + 6= 10x
Step-by-step explanation:
The first awnser is right because the x doesnt have a value therefore you keep the x but you still do the problem.
the second one is right because the same explanation for the first question but its addition and if the x had a value then you would multiply the 4 and the value of the x first then you would do the addition.

Answer:
Since BD bisects Angle ABC, Angle ABD = Angle DBC
[tex]3x+6=7x-18[/tex]
Subtract 6 from both sides:
[tex]3x+6-6=7x-18-6[/tex]
[tex]3x=7x-24[/tex]
Subtract 7x from both sides:
[tex]3x-7x=7x-24-7x[/tex]
[tex]-4x=-24[/tex]
Divide both sides by -4:
[tex]\frac{-4x}{-4}=\frac{-24}{-4}[/tex]

Step-by-step explanation:
Shown here are four frequency distributions. Each is incorrectly constructed. State the reason why.
Answer/Step-by-step explanation:
a. The the class width for the 1st, 2nd, 3rd, and 5th row equal 5 in the frequency distribution. Whereas, in the 4th row, the class width is 4 (49 - 45). This makes the construction incorrect.
b. Here, the upper limit of each consecutive class was used as the lower limit if the next class. For example, 9 is a member of the first class, which is the upper limit if the class in the first row, it ought not to be included as a member of the next class in the second row.
c. In the 3rd row, the lower limit of the class should be 133, NOT 138.
d. Different class width were used.
Row 1 class width = 13 - 9 = 4
Row 2 class width = 19 - 14 = 5
Row 3 class width = 25 - 20 = 5
Row 4 class width = 28 - 26 = 2
Row 5 class width = 32 - 29 = 3
The reason for all the frequency distribution is given below and this can be determined by using the given data.
Check all the options in order to determine the reason for the incorrect construction.
A) The given frequency table is given below:
Class Frequency
27-32 1
33-38 0
39-44 6
45-49 4
50-55 2
In the fourth row, the class should be ending with 50.
B) The given frequency table is given below:
Class Frequency
5-9 1
9-13 2
13-17 5
17-20 6
20-24 3
In the fourth row, the class should be ending with 21.
C) The given frequency table is given below:
Class Frequency
123-127 3
128-132 7
138-142 2
143-147 19
In the second row, the class should be starting from 127.
D) The given frequency table is given below:
Class Frequency
9-13 1
14-19 6
20-25 2
26-28 5
29-32 9
In the second row, the class should be starting from 13.

The number f of miles a helicopter is from its destination x minutes after takeoff is given by f (x)=40-2x. The number f of miles a commercial jet is from its destination x minutes after takeoff is shown in the graph below.
Answer:
Step-by-step explanation:
Function 'f' represents the number of miles (y-values) covered by the helicopter in 'x' (x-values) minutes.
f(x) = 40 - 2x
For x = 0,
f(x) = 40 miles
For f(x) = 0,
0 = 40 - 2x
x = 20 minutes
This shows that helicopter traveled 40 miles in 20 minutes.
Similarly, given graph shows distance covered by the jet on y-axis and duration of flight on x-axis.
For x = 0,
f(x) = 500 miles
For f(x) = 0,
x = 100 minutes
Commercial jet traveled 500 miles in 100 minutes.
The total distance and time taken for each flight are illustrations of intercepts.
The helicopter traveled 40 miles in 20 minutesThe commercial jet traveled 500 miles in 100 minutesWe have:
[tex]x \to[/tex] minutes
[tex]f(x) \to[/tex] miles
Helicopter
[tex]f(x) = 40 - 2x[/tex]
Set f(x) to 0, to calculate the x-intercept
[tex]0 = 40 - 2x[/tex]
Collect like terms
[tex]2x = 40[/tex]
Divide by 2
[tex]x =20[/tex]
Set x to 0, to calculate the y intercept
[tex]f(x) = 40 - 2x[/tex]
[tex]f(0) = 40 - 2 \times 0[/tex]
[tex]f(0) = 40[/tex]
This means that, the helicopter traveled 40 miles in 20 minutes
Commercial Jet
From the graph, the intercepts are:
[tex](x_1,y_1) = (100,0)[/tex] --- the x-intercept
[tex](x_2,y_2) = (0,500)[/tex] --- the y-intercept
This means that, the commercial jet traveled 500 miles in 100 minutes

'make g the subject' . i could really use some help please♡
Answer:
[tex]g=2T^2-6[/tex]
Step-by-step explanation:
To make g the subject, you have to isolate it in the form of g = (stuff)
-----------------------------------------------------------------------------------------------------
[tex]T=\sqrt{\frac{g+6}{2}}[/tex]
Square both sides:
[tex]T^2=\frac{g+6}{2}[/tex]
Multiply both sides by 2:
[tex]2T^2=g+6[/tex]
Swap Sides:
[tex]g+6=2T^2[/tex]
Subtract 6 from both sides:

7x^2 + 7
Step-by-step explanation:
So you collect the "like-terms". 3x^2 is not the same as 7, however, 4x^2 has the same term as 3x^2, so you add those together and then join the 7 in the expression.
Hope that explanation makes sense
Answer:
[tex]3x^{2} + 4 {x}^{2} + 7 = 7 {x}^{4} + 7[/tex]
Step-by-step explanation:
Because 3x² and 4x² are like terms, they can be added together:
3+4=7
²+²=⁴
Therefore, it will be 7x⁴.
But 7x⁴ and 7 are not like terms. So it is just 7x⁴+7

Multiply both sides by 4:

[tex]x=10[/tex]
Answer:
B:10
Step-by-step explanation:
Set up the equation
(12+50+48+x)/4=30
Add like terms
(110+x)/4=30
now multiply both sides by 4
(110+x)/4=30
4 4
110+x=120
Now subtract 110 from both sides
