A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The correct option is A and D.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is the y-intercept.
If we want to know whether a point is a solution to the equation or not, substitute it in the line and check whether both sides of the equation are equal or not.

Which would be the best name for a function that takes the time of day and returns the numbers of coffee sold at a coffee shop? Answer choices: Coffee(time) Time(coffee) Day(time) Time(shops)
Answer:
Coffee(time)
Step-by-step explanation:
A function's output variable will be:
output(input)
So we need to find the input variable and the output variable.
We know that when the time of day changes, we get a certain amount of coffee sold. This means that the amount of coffee sold is directly influenced by the time of day.
The time of day then becomes our input as the coffee sold relies on that number.
That leaves coffee sold as our output!
So the best name for a function in this scenario is Coffee(time).

Six years after a tree was planted, its height was 7 feet. Nine years after it was planted, its height was 16
feet. Which of the following equations gives the heighty, in feet, of the tree after x years if the tree grows at
a constant rate? Check all of the boxes that apply.
y - 6 =3(x - 10)
y-16 = 3(x-9)
y = 3x - 11
y=-3x - 23
I'm not good in this but.....
x = years
9x-6x = 16-7
3x = 9
x = 3
That means the tree will grow three feet per year.

Herb owanda is a computer operator for data base, inc. He earns $38,600 a year he is single and is paid on a weekly basis how much is withheld from each weekly paycheck for state taxes?
Answer: $14.85
Step-by-step explanation:
given data:
yearly earnings = $38,600
there are 52weeks in a year, so his weekly wages
= $38,600/52
= $742.31
his state tax rate falls under the 2% rate due to his income
= 2/100 * $38,600
= $772/52
= $14.85 is withheld from his weekly wages for the state tax.

Libby donated $50 during the first month of the year. If she makes three additional donations of equal amounts during the year, how much will she need to donate each time to be in the Silver category?
Answer:
She will donate P-50/3 each time
Step-by-step explanation:
Now assuming total donation needed to be in the silver category Is P
We can assume also the three additional and equal donations be Q
So
Then 50 + 3Q = P
So we still don't know P
We can get Q by saying
3Q= P - 50
Q = (P - 50) /3

True or False: Segment Y M is congruent to segment PW. GT Y BM PD W -10 -5 0 5 10 Select one: O True O False
Answer:
[tex]\huge\boxed{\mathrm{False}}[/tex]
Step-by-step explanation:
Length of YM = 1 - (-6) [This is it's endpoints]

YM = 8
Length of PW = 9 - 5 [Subtraction of endpoints to get the length]
PW = 4
So, Segment YM is not congruent to segment PW.

how to expand a using the distributive law
Answer:
2x(3x+5)+1(3x+5)
Step-by-step explanation:
The distributive law is the law that states that multiplying a number by a group of numbers is the same as doing each multiplication separately. Eg. A(B+C) =AB+AC
In the case of two sets of parenthesis it would look like:
2x(3x+5)+1(3x+5)
Which would give us:
6x^2 +10x +3x+5
6x^2+13x+5
The general format for 2 bracket ones would be:
(A+B) (C+D) =A(C+D) +B(C+D)
where the two terms in the first bracket go outside the second bracket twice individually because each term must be multiplied by all terms in the other bracket.

The distance between two communication towers is 12.654 miles. What is this distance rounded to the nearest tenth of a mile?
Answer:
12.7 miles
Step-by-step explanation:
Note the place values:
12.654
1 (tens value)
2 (ones value)
.
6 (tenths value)
5 (hundredths value)
4 (thousandths value)
~
You are rounding to the nearest tenths value. Note that when rounding, you look at the value directly next to the one you are solving for. If the digit is 5 or greater, round up. If it is 4 or less, round down.
In this case, the hundredths value is a 5, so round up.
12.654 miles rounded to the nearest tenths value is 12.7
12.7 miles is your answer.

which of the following shows the correct solution steps and solution to 3x+2=17?
Answer:
[tex]\huge\boxed{\sf x = 5}[/tex]
Step-by-step explanation:
[tex]\sf 3x + 2= 17[/tex]
Subtracting 2 to both sides
[tex]\sf 3x = 17-2\\3x = 15[/tex]
Dividing both sides by 3
[tex]\sf x = 15/3\\x = 5[/tex]
The correct solution to the equation 3x + 2 = 17 is x = 5.
Let's find the correct solution to the equation 3x + 2 = 17:
Step 1: Subtract 2 from both sides to isolate the term with 'x':
3x + 2 - 2 = 17 - 2
3x = 15
Step 2: Divide both sides by 3 to solve for 'x':
3x / 3 = 15 / 3
x = 5
So, the correct solution to the equation 3x + 2 = 17 is x = 5.

Jenny needs to sew two pieces of fabric together. One of the pieces is 3 1/12 inches and the other one is 6 5/8. What is the length of the pierce of fabric
Answer:
9 17/24in
Step-by-step explanation:
3 1/12 + 6 5/8 = length of fabric
We can add 3 and 6 since they are whole inches.
3 + 6 = 9
Now we add the fractions
1/12 + 5/8
We need to find a common denominator.
Each number goes into 24 so
1/12*(2/2) = 2/24 and 5/8*(3/3) = 15/24
2/24 + 15/24 = 17/24
So the total length of fabric is 9 17/24in

Answer:
B
Step-by-step explanation:
∠ CBD = ∠ ABE ( vertical angles ), thus
7x - 6 = 5x + 14 ( subtract 5x from both sides )
2x - 6 = 14 ( add 6 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
Thus
∠ ABE = 5x + 14 = 5(10) + 14 = 50 + 14 = 64° → B
