Answer:
The equation for a zero slope line is one where the X value may vary but the Y value will always be constant. An equation for a zero slope line will be y = b, where the line's slope is 0 (m = 0).
The y-intercept of the equation will be at (0, 81). Then the correct option is A.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
y - 3 = 13(x + 6)
Convert the linear equation into slope-intercept form. Then the equation is written as,
y - 3 = 13x + 78
y = 13x + 78 + 3
y = 13x + 81
The y-intercept of the equation will be at (0, 81). Then the correct option is A.

If m<1 = 38 then m<4 =
Answer:
If m<1 = 38 then m<4 = 38
Step-by-step explanation:
Both of the angles equal 38 degrees. This is true because the angles are vertical, vertical angles are angles opposite each other where two lines cross. Vertical angles are also always congruent, therefore the m<4=38.

The length of a tarpaulin is 3ft. more than thrice its width and its area is 126ft². What is the length of the tarpaulin?
Answer:
Length = 22 ft
Width = 6 ft

Let the width of the tarpaulin be x meters.
Therefore, length = 3x + 3
Area of tarpaulin = 126 ft²
[tex]x(3x + 3) = 126 \\ \\ 3x(x + 1) = 126 \\ \\ {x}^{2} + x = \frac{126}{3} \\ \\ {x}^{2} + x = 42 \\ \\ {x}^{2} + x - 42 = 0 \\ \\ {x}^{2} + 7x - 6x - 42 = 0 \\ \\ x(x + 7) - 6( {x + 7)} = 0 \\ \\ (x + 7)(x - 6) = 0 \\ \\ x + 7 = 0 \: \: or \: \: x - 6 = 0 \\ \\ x = - 7 \: \: or \: \: x = 6 \\ \\ \because \: x \: is \: side \: length \\ \therefore \: it \: can \: not \: be \: negative \\ \implies \: x \notin - 7 \\ \\ \implies \: x = 6 \\ \\ 3x + 3 = 3 \times 6 + 3 \\ \\ 3x + 3 = 18 + 3 \\ \\ 3x + 3 = 21 \\ \\ length \: of \:the \: tarpaulin \: = 21 \: ft \\ \\ width \: of \: the\: tarpaulin \: = 6 \: ft \\ [/tex]

The Newtown Telephone Company advertises that if you use their 10-10 service, you will always pay only 9c per minute, no matter where you call within the country. Its major rival, Tryus Telephone Company, charges only 3c per minute, but you must pay a 36 c "connection fee" per call.
Create a cost equation for each telephone company where y is the total cost for each phone call (in cents), and x is the number of minutes the phone call lasts. Write a system of equations.
Answer:
y = 9x cents
y = (36 + 3x) cents
Step-by-step explanation:
Given that:
Newtown telephone company :
Fee per minute = 9c
Tyrus company :
Fee per minute = 3c
Connection fee = 36c
Cost equation :
y = total cost for each phone call:
x = minutes phone call last ;
Newton Company :
y = (fee per minute * minute phone call last)
y = 9 * x
y = 9x cents
Tyrus Company:
y = (connection fee + (fee per minute * minute phone call last))
y = (36 + (3 * x))
y = (36 + 3x) cents

Tyler has a bag that contains orange chews, cherry chews, and peach chews. He performs an experiment. Tyler randomly removes a chew from the bag, records the result, and returns the chew to the bag. Tyler performs the experiment 38 times. The results are shown below:
A orange chew was selected 28 times.
A cherry chew was selected 7 times.
A peach chew was selected 3 times.
Based on these results, express the probability that the next chew Tyler removes from the bag will be peach chew as a percent to the nearest whole number.
Answer:
8%
Step-by-step explanation:
Mathematically, the probability of an event can be obtained by dividing the expected number in which event will turn up divided by the total number we have in the sample space
From the question, the total number of times in which the experiment is performed is 38 times
The number of times we have the peach chew selected is 3 times
So the probability that the next removal will be a peach chew will be;
3/38 = 0.079
This as a percent is 7.9%
To the nearest whole number, this figure is 8%

Write the equation of the line passing through the point (-2, 2) that is parallel to the line y = 2x + 3
Hi there! :)
[tex]\large\boxed{y = 2x + 6}[/tex]
A line that is parallel to y = 2x + 3 must have the same slope of 2. Therefore:
We can use the given point as well as the slope-intercept formula y = mx + b to solve.
Plug in the x-coordinate for "x" and y-coordinate of the point into "y":
2 = 2(-2) + b
2 = -4 + b
6 = b
Rewrite the equation:
y = 2x + 6

If the given points in the table lie on a line, then the slope of a line is, 4
What is slope?Slope is a ratio of change in y-coordinate w.r.t. change in x-coordinate. The net change in y coordinate is written as, Δy and the net change in x coordinate is written as, Δx.
So formula for the slope is,
m = change in y coordinate/change in x coordinate = Δy/Δx
Given that,
Coordinates of a point through which line is passing,
X: 1 3 5 7
Y: 2 10 18 26
The slope of a line = ?
The slope of a line can be calculated by finding the rise (difference in the y-values) over the run (difference in the x-values) between two points on the line.
Now, Using the first and last points in the table:
First point- (1, 2)
Second Point- (7, 26)
Slope = (y₂ - y₁)/(x₂ - x₁)
Slope = (26 - 2) / (7 - 1)
= 24 / 6
= 4
The slope of the line is 4.

The amount a basketball coach spends at a sporting goods store depends on the number of basketballs the coach buys. The situation is represented by the function rule a=16b.
A.) Make a table of values and graph the function rule. Is the graph continuous or discrete? Explain.
B.) Suppose the coach spent $128 before tax. How many basketballs did she buy?
Answer: 0,16,32,48,64
Step-by-step explanation: the equation 16b means you will multiple 16 by whatever is in the b box. For the first b is equal to 0 so 16x0 = 0, the second b is equal to 1 so 16x1 = 16
The discrete graph for the function rule is plotted and the coach will buy 8 basketballs for $128.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is the amount which a basketball coach spends at a sporting goods store and it depends on the number of basketballs the coach buys. The situation is represented by the function rule a = 16b.
The given equation is -
a = 16b
where -
[a] represents the amount spend by the basketball coach.
[b] represents the number of basketballs buyed.
PART - AThe table is given as follows -
[b] [a]
0 0
1 16
2 32
3 48
4 64
The graph of the representing the function rule - a = 16b is attached with the answer. The graph is discrete as number of basketballs cannot exist in fractions. This means the possible values of [b] will be whole numbers only.
PART - B
If coach spent $128, then the number of footballs bought will be -
b = 128/16
b = 8
Number of footballs bought were 8.
Therefore, the discrete graph for the function rule is plotted and the coach will buy 8 basketballs for $128.
