Determine whether the graph represents a proportional relationship. (4 points)
A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 10. Four points are shown on the graph on ordered pairs 0, 0 and 1, 3 and 2, 6 and 3, 7. These points are joined by a line. The label on the x-axis is Number of pans. The title on the y-axis is Number of cakes.
Group of answer choices
A. Yes, it is a proportional relationship because the graph goes through the origin
B. Yes, it is a proportional relationship because the graph is a straight line
C. No, it is not a proportional relationship because the graph is not a straight line
D. No, it is not a proportional relationship because the graph does not go through the origin
Answer:
C. No, it is not a proportional relationship because the graph is not a straight line

The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). What is m+n?
Answer:
the aswer is 32
Step-by-step explanation:
The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). the sum of m + n is 178/27.
To find the vertex of the parabola described by the equation 3y = 2x^2 - 16x + 18, we first need to put the equation in the standard form of a parabola, which is y = a(x - h)^2 + k, where (h, k) represents the vertex.
Let's begin by dividing the entire equation by 3 to simplify it:
y = (2/3)x^2 - (16/3)x + 6
Now, we need to complete the square to rewrite the equation in the form y = a(x - h)^2 + k:
y = (2/3)(x^2 - (8/3)x) + 6
Next, we need to find the value that completes the square for the expression inside the parentheses. To do that, we take half of the coefficient of x and square it:
(8/3) / 2 = 4/3
(4/3)^2 = 16/9
Now, we add and subtract 16/9 inside the parentheses:
y = (2/3)(x^2 - (8/3)x + 16/9 - 16/9) + 6
Now, we group the first three terms and factor the perfect square trinomial:
y = (2/3)((x - 4/3)^2 - 16/9) + 6
Next, distribute the (2/3):
y = (2/3)(x - 4/3)^2 - (2/3)(16/9) + 6
Now, simplify:
y = (2/3)(x - 4/3)^2 - (32/27) + 6
Finally, bring everything together:
y = (2/3)(x - 4/3)^2 + (142/27)
Now we can see that the vertex of the parabola is at the point (h, k) = (4/3, 142/27).
To find m + n, we simply add the x-coordinate (h) and the y-coordinate (k):
m + n = 4/3 + 142/27
To add these fractions, we need to find a common denominator, which is 27. Convert 4/3 to have a denominator of 27:
4/3 = (4/3) * (9/9) = 36/27
Now we can add the fractions:
m + n = 36/27 + 142/27
m + n = (36 + 142)/27
m + n = 178/27

square root of 9
-0.25
pi
0.6 (the six has a line over it)
Answer:
3^-1, square root of 9, -0.25, and 0.6
Step-by-step explanation:
Rational numbers are numbers that you can turn into fractions.
3^-1 = 0.3333333333... which is also known as 1/3
square root of 9 = 3, which can be written as 3/1
-0.25 can be written as -1/4
0.66666666... = 2/3
The numbers 3⁻¹ , sqrt(9), -0.25 and 0.6 are the rational numbers.
What is Number system?A number system is defined as a system of writing to express numbers.
The rational numbers are those that can be expressed as a ratio of two integers.
3⁻¹ = 1/3, which is a rational number.
sqrt(12) = sqrt(4 x 3) = 2sqrt(3), which is irrational.
sqrt(9) = 3, which is a rational number.
-0.25 = -1/4, which is a rational number.
pi is irrational.
0.6 = 3/5, which is a rational number.
Hence, 3⁻¹ , sqrt(9), -0.25 and 0.6 are the rational numbers.

The length of the Titanic was 882 feet. Porter's history class is building a model of the Titanic. The model is 1/100 of the actual length of the ship. How long is the model?
Answer:
8.82 feet
Step-by-step explanation:
Explanation:
Let's set up the ratio. We know that the actual length of the ship was 882 feet and we want to know how long the model will be. We also have a ratio of 1 model length to every 100 actual length. So we can write this as:
Model length
Ship length
=
1 Model length
100 actual length
And we can drop in some numbers (I'll also put in the variable
x
to represent the length of the ship model):
x
882
=
1
100
Let's cross multiply to solve for x:
100
x
=
882
x
=
8.82
