Answer:
False.
Step-by-step explanation:
It is false because when dividing an odd number by an odd number, it usually isn't divisible. In this case, 690,269. Is an odd number, because the last number, 9, is odd, which makes the whole thing odd. So, odd divided by odd never turns out well. (By the way the answer is 76,696.5555556).

The graph below models how one county fines drivers that get a ticket for speeding based on how many miles over the speed limit. Based on the graph, what would the fine be for a person that was ticketed for driving 62 mph in a zone that had a maximum speed of 55 mph?
$150
$100
$50
$200
Answer:
$100
Step-by-step explanation:
The bottom row is how many mph the driver is over, the left row is how much it costs per mph over. Since 62mph in a 55mph zone is 7mph over, you go the 7 on the bottom, and go up until you get to the point, then see what the number on the left is. In this case, it would be 100. So therefore the fine is $100.
A photograph measures 10 inches wide by 18 inches long. The picture is reduced so that the length is 6 inches, what is the new width?
Answer:
19
Step-by-step explanation:
Answer:
The width would be 3 1/3 inches or 3.333 repeating
Step-by-step explanation:
Since you divide the length by 3, you would also have to divide the width by 3. 10 divided by 3 is 3 1/3 or 3.333 repeating (whichever one you choose).
Which relation is a function? Help please
Answer:
The bottom right (v shaped one) is a function
Step-by-step explanation:
Hope this helps:)
Answer:
The one in the bottom right that is an absolute value function.
Step-by-step explanation:
You can use the "vertical line test" to determine whether a given graph is a function or not. If you can draw a straight, vertical, line anywhere and it intersects the graph more than once, then it is not a function. The one in the bottom right is therefore the answer.

Answer:
(a) 1
(b) 1 3/4
(c) [-2, 4]
(d) [-1/4, 2]
Step-by-step explanation:
Apparently, the vertex of the graph is (1, 2) and it goes through points (-1, 1) and (3, 1). In vertex form, the equation for this is ...
y = a(x -1)^2 +2
We can find the value of 'a' from the point (3, 1):
1 = a(3 -1)^2 +2 = 4a +2 . . . . substitute for x and y, and simplify
-1 = 4a . . . . . . . subtract 2
-1/4 = a . . . . . . divide by 4
So, ...
f(x) = -1/4(x -1)^2 +2
__
(a)Above, we assumed point (-1, 1) was on the graph:
f(-1) = 1
__
(b)Using the equation we found, ...
f(2) = -1/4(2 -1)^2 +2 = -1/4 +2
f(2) = 1 3/4
__
(c)The domain is the horizontal extent of the graph, apparently from x = -2 to x = 4.
domain: [-2, 4] or -2 ≤ x ≤ 4
__
(d)The range is the vertical extent of the graph. The minimum can be found at the end of the domain:
f(4) = -1/4(4 -1)^2 +2 = -9/4 +2 = -1/4
The maximum has already been established as the vertex at y=2.
range: [-1/4, 2] or -1/4 ≤ y ≤ 2

(b) Estimate
B B B 1 , 2 , and 3
. Explain how you determined these amounts.
(c) Jade said that the amount of money Ebony took out of her account each day between Day 8 and Day
12 was the same amount of money she put into her account each day between Day 0 and Day 4.
Recall that Day 12 is when the balance first reached $0. Without doing any calculations, how could
you show Jade why that cannot be true?
Answer: Answer:Step-by-step explanation:a) On day 4, her balance = $400on day 5, her balance = $0on day 6, her balance = $400on day 7, her balance = $0on day 8, her balance = $400From the above illustration, Ebony withdraws all the money and deposits the same amount, each every other days.c) I do not think so, perhaps, she must have been doing that previously, between day 4 and day 8, but have changed her way of withdrawals and savings between day 8 and day 12.

The graph of a proportional relationship contains the point (20, 4) .
What is the corresponding equation?
Enter your answer as a fraction in the simplest form by filling in the boxes.
Answer:
Below :D
Step-by-step explanation:
Corresponding equation:
A relationship represents a proportional diagram.
So we can express it as, y/x=k
Answer= y 1/5x
substitute (20,4)
4= 20x/.
Divide both sides by 20.
so we have.
y=1/5x.
Answer:
[tex] \frac{y - y1}{x - x1} \\ \frac{y - 4}{x - 20} \\ m = \frac{y - 4}{x - 20} \\ 1 = \frac{y - 4}{x - 20} \\ x - 20 = y - 4 \\ - y = - x - 4 + 20 \\ - y = - x + 16 \\ \frac{ - y}{ - } = \frac{ - x}{ -} + \frac{16}{ - } \\ y = x - 16[/tex]

Using the graph of f(x) and g(x), where g(x) = f(k⋅x), determine the value of k.
Answer:
1/3
Step-by-step explanation:
This is about the interpretation of the graph
From the graph, we can see the 2 lines representing function f(x) and function g(x).
Now for us to find the value of x in g(x) = k⋅f(x), we need to get a mutual x-coordinate where we can easily read their respective y-coordinate values.
We see that the best point for that is where x = -3.
For f(x), when x = -3, y = 1
For g(x), when x = -3, y = -3
we can rewrite them as;
x = -3, f(-3) = 1 and x = -3, g(-3) = -3
Let us plug in the relevant values into g(x) = k⋅f(x) to get;
-3 = k(1)
Thus; k = -1/3

Amy will be using a t-chart to find 3 points for this linear function: f(x)= 3x -2. Which chart below is the correct answer for this function. WILL GIVE BRAINLIEST
The points for a linear function are (0, -2), (1, 1) and (2, 4)
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Given that the relationship between f(x) and x is given by:
f(x) = 3x - 2
When x = 0: f(0) = 3(0) - 2 = -2
When x = 1: f(1) = 3(1) - 2 = 1
When x = 2: f(2) = 3(2) - 2 = 4
The points for a linear function are (0, -2), (1, 1) and (2, 4)

What is the solution to the system of equations? (Hint: Use Substitution.)
2 lines Line 1: y equals negative 3 x plus 6 Line 2: y equals 9
Answer:
(-1,9)
Step-by-step explanation:
y = -3x + 6
y = 9
-3x + 6 = 9
-3x = 3
x = -1
y is already given as 9, but you can solve for y by plugging the x value into y = -3x + 6,
-3(-1) + 6 = 9
(-1,9)

What is the sum of the measures of the interior angles of a 20-sided figure?.
Answer:
3240°
Step-by-step explanation:
The equation to find the sum of the measures of the interior angles of a figure is:
(n-2)*180
Where n represents the amount of sides the figure has. In this case the figure has 20 sides so its interior angles sum up to:
(20-2)*180=18*180=3240°

Answer:
Step-by-step explanation:
Angle j is the measure of the interior angle of a regular hexagon, so its measure is 180(4/6) = 120 degrees.
Angle k can be found using the fact that the sum of the interior angles of a quad is 360.
So k = 360 - 180 - 142 = 38 degrees
