if b is the midpoint of ac, ab=12x+11 and bc= 14x - 1, find AB
ik i said i didn't need help with this in my last question but I lied
Answers
Answer:
AB = 83
Step-by-step explanation:
The mid-point of any segment divides the segment into two equal parts
∵ B is the midpoint of segment AC
→ That means B divides AC into two equal segments AB and BC
∴ AB = BC
∵ AB = 12x + 11
∵ BC = 14x - 1
→ Equate them
∴ 14x - 1 = 12x + 11
→ Subtract 12x from both sides
∵ 14x - 12x - 1 = 12x - 12x + 11
∴ 2x - 1 = 11
→ Add 1 to both sides
∵ 2x - 1 + 1 = 11 + 1
∴ 2x = 12
→ Divide both sides by 2
∵ [tex]\frac{2x}{2}=\frac{12}{2}[/tex]
∴ x = 6
→ To find AB substitute x by 6 in its expression
∵ ab = 12x + 11
∵ x = 6
∴ AB = 12(6) + 11
∴ AB = 72 + 11
∴ AB = 83

The distance a race car travels is given by the equation d=v0t+12at2 where v0 is the initial speed of the race car, a is the acceleration, and t is the time travelled. Write an equation for the driver's average speed s during the acceleration. (Hint: Average speed is equal to distance divided by time.)
Answers
Answer:
v0 + 1/2at
Step-by-step explanation: Given that the distance a race car travels is given by the equation d = v0t+12at2 where v0 is the initial speed of the race car, a is the acceleration, and t is the time travelled.
The equation for the driver's average speed s during the acceleration will be:
(v0t+12at2) / t
Since Average speed is equal to distance divided by time.
Therefore, the equation will be:
v0+1/2at
The average speed s (technically average velocity) at time t will be given by the equation:
[tex]s = v_0 + \dfrac{1}{2} \times a \times t[/tex]
Given that:
If d denotes the distance travelled by the car with initial velocity [tex]v_0[/tex] and acceleration a, then:
[tex]d = v_0\times t + \dfrac{1}{2} \times a \times t^2[/tex]
And since average speed is total distance divided by total time taken, thus let the average speed is denoted by s, then:
[tex]s = v_0 + \dfrac{1}{2} \times a \times t[/tex]
The terms speed and distance here, are technically referring to the terms velocity and displacement respectively since speed and distance are scalar quantities.

Here is a linear equation in two variables: 2x + 4y - 31 = 123.
Solve the equation, first for x and then for y.
Answers
Answer:
x = -2y+77
y = -x/2+77/2
Step-by-step explanation:
The equation for x variable is x = 77 - 2y and for y variable it is; y = 77- x/2
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
WE have been given linear equation in two variables: 2x + 4y - 31 = 123.
Solve for x and for y
2x + 4y - 31 = 123.
Add 31 to both sides
2x + 4y - 31 + 31 = 123 + 31
2x + 4y = 154
Solving for x then Subtract 4y from both sides
2x + 4y -4y = 154 - 4y
2x = 154 - 4y
Divide by 2
x = 77 - 2y
y = 77- x/2

Answer:
x= 15 /7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8x− 6 /2 =x+12
8x+−3=x+12
8x−3=x+12
Step 2: Subtract x from both sides.
8x−3−x=x+12−x
7x−3=12
Step 3: Add 3 to both sides.
7x−3+3=12+3
7x=15

7x /7 = 15 /7

[tex]\boxed {x = \frac{15}{7}}[/tex]
Step-by-step explanation:

[tex]8x - \frac{6}{2} = x + 12[/tex]
-Divide [tex]6[/tex] by [tex]2[/tex]:
[tex]8x - \frac{6}{2} = x + 12[/tex]
[tex]8x - 3 = x + 12[/tex]
-Take [tex]x[/tex] and subtract from [tex]8x[/tex]:
[tex]8x - 3 - x = x - x + 12[/tex]
[tex]7x - 3 = 12[/tex]
-Add both sides by [tex]3[/tex]:
[tex]7x - 3 + 3= 12 + 3[/tex]
[tex]7x = 15[/tex]
-Divide both sides by [tex]7[/tex]:
[tex]\frac{7x}{7} = \frac{15}{7}[/tex]
[tex]\boxed {x = \frac{15}{7}}[/tex]
So, the value of [tex]x[/tex] is [tex]\frac{15}{7}[/tex].

Elena collects 112 specimens of beetle and records their lengths for an ecology research project. When she
returns to the laboratory, Elena finds that she incorrectly recorded one of lengths of the beetles as 122
centimeters (about 4 feet). What should she do with the outlier, 122 centimeters, when she analyzes her data?
A.
She should exchange the recording error with the average length from her other measurements.
B. She should take the 4 foot long beetle to Guinness Book of Records
C.She should go back and remeasure all of her specimens again to find the error. If she can't do this, she should eliminate the
outlier from her analysis, because this is an error in recording.
Answers
Answer:
The correct option is;
C. She should go back and remeasure all of her specimens again to find the error. If she can't do this, she should eliminate the outlier from the analysis, because this is an error in recording
Step-by-step explanation:
In order to minimize error in measurement, some valuable steps includes;
1) Perform a double check on all measurements to ensure that the measurements recorded are accurate
2) Ensure proper training before taking measurements
3) Measurements should only be taken under controlled conditions
4) Separate the entire population into smaller groups for proper recording
5) Have a second observer double check the records
