Answer:
If m is the midpoint of ab it means am is equal to mb
am = 3x + 8 and mb = 6x-4
and ab = am + mb
first find the value of x by using am = mb
3x + 8 = 6x - 4
8 + 4 = 6x - 3x
12 = 3x
x = 4
ab = 3 (4) + 8
= 12 + 8 = 20 = mb
ab = am + mb
= 20 + 20
40
so, the value of ab is 40

Answer:
1). x = 81
2). x = 84
Step-by-step explanation:
1). By applying geometric mean theorem in the given triangle,
[tex]\frac{x}{18\sqrt{14}}= \frac{18\sqrt{14}}{56}[/tex]
56x = (18√14)²
56x = 4536
x = [tex]\frac{4536}{56}[/tex]
x = 81
2). By applying geometric mean theorem,
[tex]\frac{x}{8\sqrt{21}}= \frac{8\sqrt{21} }{16}[/tex]

Jasper is eating tacos at a constant rate. The amount of tacos depends on time.
y= 2.5x
y is the number of tacos eaten
x is the time in minutes
what is the rate of change of jaspers taco eating capabilities?
how many tacos will jasper consume in 9mins
Answers
Answer:
The rate of change, I believe, based on what you have given us in terms of information, would be 2.5. Because Jasper would eat 2.5 tacos per minute; thus, the rate would increase by 2.5 each time.
And for the second part, you would simply multiply 2.5 by 9 to get 22.5. Jasper would eat 22.5 tacos in 9 minutes.

6. Graph the following system of linear inequalities. Identify at least two points in the solution: y < 5 - 2x x + 5y > -7
Answers
Step-by-step explanation:
The price of Xbox one = $500
Sales tax = 10%
The total cost of Xbox one = 500 + (10% × 500 )
= 500 + (0.010 × 500)
= 500 + 50
= $550
Anakin currently has = $165
He earns per week = $40
Let the time (in weeks) will take for him to save the amount be t
165 + (40t) = 550
40t = 550 - 165
40t = 385
t =
t = 9.625 ≈ 10 weeks
It will take 10 weeks to save the amount.

The ratio of the number of text messages sent by Diego to the number of text messages sent by his sister is 3 to 4. Diego sent 18 text messages. How many more text messages did his sister send?
Answers
Answer:
His sister sent 6 more messages than Diego.
Step-by-step explanation:
Ratio of Diego's messages to his sister's messages = 3 : 4
Text messages sent by Diego = 18
Text messages sent by his sister = x
Ratio = 18 : x
It is a proportional relationship,
3 : 4 :: 18 : x
Product of extremes = Product of means
3x = 18*4
3x = 72
[tex]\frac{3x}{3}=\frac{72}{3}\\x=24[/tex]
Difference = 24 - 18 = 6
Therefore,
His sister sent 6 more messages than Diego.

Answer:
80 degrees
Step-by-step explanation:
The total angle measure of a triangle, no matter the type, is always 180 degrees.
Using this, we can calculate the missing angle:
[tex]180=65+35+x[/tex]
[tex]x=180-(65+35)[/tex]
[tex]x=180-100[/tex]
[tex]x=80[/tex]
The measure of angle x in the triangle is 80 degrees.
What is the measure of angle x?The figure in the image is a triangle.
From the diagram:
Angle 1 = x
Angle 2 = 65 degrees
Angle 3 = 35 degrees
To solve for the measure of angle x, we use the fact the the sum of the interior angle of a triangle equals 180 degrees.
Hence:
Angle 1 + Angle 2 + Angle 3 = 180
Plug in the values:
x + 65 + 35 = 180
Collect and add like terms:
x + 100 = 180
Subtract 100 from both sides:
x + 100 - 100 = 180 - 100
x = 180 - 100
x = 80°
Therefore, angle x has a measure of 80 degrees.

A restaurant offers a catering service which costs $25.00 per person with a $119.50 service charge. For parties of 50 or more people, a group discount applies, and the cost is $20.00 per person along with the service charge dropping to $59.00. (a) Write a piecewise-defined linear function which calculates the total cost T of the catering service which serves n people.
Answers
Answer:
T1(n) = 25n +119.50 where n belongs to [tex]1 \leq n <50[/tex].
T2(n) = 20n + 59 where n belongs to [tex]50\leq n[/tex].
Step-by-step explanation:
We are given two situations first is for normal days and the other is for days when 50 or more people are going to this restaurant for the party.
Let the number of person going for this restaurant be "n"
For normal day, we are given
catering service = $25 per person
service charge = $119.50
Let the total cost of the restaurant be T
Cost for this case will be T1
T1(n) = 25n +119.50 where n belongs to [tex]1 \leq n <50[/tex]
similarly for the case when 50 or more than that goes to this restaurant for party.
cost after discount
Catering service = $20.00 per person
service charge = $59.00
now the cost of this case will be T2
T2(n) = 20n + 59 where n belongs to [tex]50\leq n[/tex].
Therefore the two piecewise linear functions represents the total cost of the restaurant for serving n people.

O y = 2x + 4
O y = 2x - 8
Answers
Answer:
The equation of a parallel line in the slope-Intercept form that contains the point (3,-2) is:
y = 2x- 8Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven the equation of a line
y = 2x + 4
comparing with the slope-intercept form of the line equation
The slope of the line AB is m = 2
We know that the parallel lines have the same slope.
Thus, the slope of the new line is also 2.
now we have,
The slope of new line m = 2The point = (3, -2)Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 2 and the point (x₁, y₁) = (3, -2)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
y - (-2) = 2(x - 3)
y + 2 = 2x - 6
subtracting 2 from both sides
y + 2 - 2 = 2x - 6 - 2
y = 2x- 8
Therefore, the equation of a parallel line in the slope-Intercept form that contains the point (3,-2) is:

Answer:
[tex]P(Tail = 1) = \frac{1}{2}[/tex]
Step-by-step explanation:
Given
[tex]Flips = 2[/tex]
Required
Probability of exactly one tail
This event can be represented as:
(Head and Tail) or (Tail and Head)
In the flip of a coin (penny), the following probabilities exist:
[tex]P(Head) = \frac{1}{2}[/tex]
[tex]P(Tail) = \frac{1}{2}[/tex]
So, the required probability is:
[tex]P(Tail = 1) = (P(Head) * P(Tail)) + (P(Tail) * P(Head))[/tex]
Substitute values for P(Head) and P(Tail)
[tex]P(Tail = 1) = (\frac{1}{2}*\frac{1}{2}) + (\frac{1}{2}*\frac{1}{2})[/tex]
[tex]P(Tail = 1) = (\frac{1}{4}) + (\frac{1}{4})[/tex]
[tex]P(Tail = 1) = \frac{1}{4} + \frac{1}{4}[/tex]
Take LCM
[tex]P(Tail = 1) = \frac{1+1}{4}[/tex]
[tex]P(Tail = 1) = \frac{2}{4}[/tex]
[tex]P(Tail = 1) = \frac{1}{2}[/tex]
