Answer: AB is 15
Step-by-step explanation: First, you need to draw a picture and label the parts of the line: AB=5x-15; BC= 3x-5; AC =28. Because of the segment addition postulate, you set the equation to be 5x-15+3x-5=28. Then you solve:
5x-15+3x-5=28
Add like terms:
8x-20=28
Add 20 to both sides
8x=48
Divide by 8
x=6
Now, you need to find the measure of AB, so you plug the 6 into the x variable for 5x-15
5(6)-15
30-15
AB=15

Find an equation for the line below. 
Answer:
y = -¼x + ½Step-by-step explanation:
Given points (-2, 1) and (6, -1):
Start by solving for the slope of the line, using the following formula:
m = (y2 - y1)/(x2 - x1)
Let (x1, y1) = (-2, 1)
(x2, y2) = (6, -1)
m = (y2 - y1)/(x2 - x1)
m = (-1 - 1)/[6 - (-2)]
m = -2/(6 + 2) = -2/8 = -¼
Therefore, the slope of the line is m = - ¼.
Next, to determine the y-intercept (b), use one of the given points (6, -1) and the slope, and plug in these values into the slope-intercept form:
y = mx + b
-1 = -¼(6) + b
-1 = -3/2 + b
-1 + 3/2 = -3/2 + 3/2 + b
½ = b
Therefore, the y-intercept, b = ½.
The linear equation of the given graph is:
y = -¼x + ½Combine the like terms to create an equivalent expression:

Answer:
D
Step-by-step explanation:
The mass of the proton has an exponential of -27 and the electron has -31.
Negative 27 is larger than negative 31 so you know the proton is larger than the electron in mass.
9.1 divided by 1.7 is approiximately 5.
Those exponents are 4 digits apart. 31 - 27 = 4 so there are 4 zeroes added onto the 5.
So the proton is about 50,000 times bigger than the electron in mass.

Quadrilateral DEFT has vertices D(2, 7), E(-4, 4), F(5, -6), and T(11, -3). What is the best name for quadrilateral DEFT?
Answer:
parallelogram
Step-by-step explanation:
slope of DE = (4-7) / (-4 - 2) = 1/2
slope of FT = (-3 - -6) / (11-5) = 1/2
DE // FT
slope of EF = (-6 - 4) / (5 - -4) = - 10/9
slope of DT = (-3 - 7) / (11 - 2) = - 10/9
EF // DT
The quadrilateral is formed by the vertices D(2, 7), E(-4, 4), F(5, -6), and T(11, -3) will be a parallelogram.
What is a parallelogram?A parallelogram is a quadrilateral having four sides and the two opposite sides are equal and parallel to each other.
Given that quadrilateral, DEFT has vertices D(2, 7), E(-4, 4), F(5, -6), and T(11, -3).
Slope of DE = (4-7) / (-4 - 2) = 1/2
Slope of FT = (-3 - -6) / (11-5) = 1/2
DE is parallel to FT.
Slope of EF = (-6 - 4) / (5 - -4) = - 10/9
Slope of DT = (-3 - 7) / (11 - 2) = - 10/9
EF is parallel to DT.
Therefore, the quadrilateral is formed by the vertices D(2, 7), E(-4, 4), F(5, -6), and T(11, -3) will be a parallelogram.

-3+(-6) is ___ units from -3 in the positive or negative direction.
Answer:
-3+(-6) = -9
Step-by-step explanation:
a negative 3 plus another negative 6 is a negative 9. Is just like if you borrow $3 from your friend and borrow $9 from another friend. That means you own two of your friends a total of $9. This can be mathematically illustrate as: -3 + (-6)= -9

write the slope intercept form of the equation for each line
Answer:
y = x + 2
Step-by-step explanation:
slope-intercept form is y=mx+b
The y-intercept ( b ) is the point where the line touches the y-axis. in this case, 2
The slope, m, is rise over run. You can see that as the graph rises 2, it also runs 2.
The fraction is 2/2 which simplifies to 1
Slope-intercept form is y = 1x + 2, or y = x + 2

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 95 miles per hour. The westbound train travels at 115 miles per hour. How long will it take for the two trains to be 546 miles apart?
Do not do any rounding.
Answer:
2 hours and 36 minutes
Step-by-step explanation:
First you calculate the sum of the speeds:
115 + 95 = 210, It means every hour they get 210 miles apart.
Now the question wants the time of 546 miles apart.
You need to divide 546 to 210.
[tex]\frac{546}{210}=2.6[/tex], It gives us 2.6 hours.
2 hours + 0.6 hour.
2 hours + 0.6 × 60 minutes = 2 hours + 36 minutes

3) 10
inches
4) Sinches
Answer:
10/3π ≈ 10.47
Step-by-step explanation:
Length of an arc = central angle/°in a circle · the formula for circumference of the circle.
Length of an arc = 120/360 · 2πr
Length of an arc = 1/3 · (2·π·5)
Length of an arc = 1/3 ·10π
Length of an arc = 10/3π ≈ 10.47
