Proportional equations are the equations that have the graph which pass through (0,0).
y = -9x is proportional.
y=x is proportional
y=1/2x is proportional
That's it. Only these three equations have (0,0) intercept.

The residual plot obtained follows a linear pattern, Hence, it shows that the line of best fit is not appropriate for the data.
The residual plot is a plot with the independent variable on the horizontal (x-axis) and the residual values (difference between the observed and predicted values) in the vertical x-axis.
• If a residual plot has it's points randomly scattered (has no pattern) around the horizontal axis. It depicts that the linear model is a good fit for the data. If otherwise, then the linear model isn't a good fit as it signifies that the data has a non-linear relationship.
Since, the data of the residual plot given above shows a linear pattern, then it shows that the line of best fit is not appropriate for the data.

5. Solve each equation.
a.
6(3x - 5) - 7x = 25
Answers
Answer:
Step 1: Simplify both sides of the equation.
6(3x−5)−7x=25
(6)(3x)+(6)(−5)+−7x=25(Distribute)
18x+−30+−7x=25
(18x+−7x)+(−30)=25(Combine Like Terms)
11x+−30=25
11x−30=25
Step 2: Add 30 to both sides.
11x−30+30=25+30
11x=55
Step 3: Divide both sides by 11.
x=5
Step-by-step explanation:
The solution to the equation is x = 5.
To solve the equation 6(3x - 5) - 7x = 25, we need to simplify and isolate the variable x. Let's break it down step by step:
Distribute the 6 to the terms inside the parentheses:
18x - 30 - 7x = 25
Combine like terms on the left side of the equation:
(18x - 7x) - 30 = 25
11x - 30 = 25
Move the constant term to the right side by adding 30 to both sides:
11x = 25 + 30
11x = 55
Finally, isolate x by dividing both sides of the equation by 11:
x = 55 / 11
x = 5
Hence, the solution to the equation is x = 5. By simplifying and applying algebraic operations, we find that when x is equal to 5, the equation 6(3x - 5) - 7x = 25 holds true.

The value of u · v is -6 if the u = <1, √3> and |v| = 6, and the angle between the vectors is 120° option (b) is correct.
What is a vector?It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.
It is given that, u = <1, √3>
The magnitude of u:
|u| = √(1²+√3²)
|u| = 2
|v| = 6
The product of vectors is calculated:-
u · v = |u||v|cos120
u · v = 2(6)(-0.5)
u · v = -6
Hence, option (b) is correct.

Dilations
Quadrilateral A'B'C'D' is the result of dilation of quadrilateral ABCD by a scale factor.
To find the scale factor, we compare the measures of the side lengths from consecutive vertices of each quadrilateral.
From A to B, there are 4 units. From A' to B' there is one unit. This gives a scale factor of 1/4.
This happens with the rest of the measures.
From B to C there are 4 horizontal and 4 vertical units. From B' to C' there is one unit of each dimension.
This pattern can be confirmed by comparing any pair of vertices of each quadrilateral, thus we can conclude:
The scale factor is 1/4.

Mmmm! I love cafe de olla this time of year, and so do
my neighbors. My recipe calls for two quarts of water,
three sticks of cinnamon, and one tablespoon of coffee.
This will make enough for eight people to share. In my
neighborhood, however, there are 36 people. How much
do I need of each ingredient to make enough for my
whole neighborhood to share?
Answers
Answer:
Step-by-step explanation:
you want to divide 36 by 8 because you have 36 people and the recipie only makes it for 8.
You know that you will need to make the recipe 4.5 times.
So, multiply all the ingredient numbers by 4.5
2 x 4.5 = 9 quarts of water
3 x 4.5 = 13.5 sticks of cinnamon
1 x 4.5 = 4.5 tablespoons of coffee
Answer: Im pretty sure you need 16 quartz of water, 24 sticks of cinnamon, and 8 tablespoons of coffee.

7x + 3 (3x+6) = 194 what is the answer
Answers
Answer:
x = 11
Step-by-step explanation:
7x + 3(3x + 6) = 194
open the parenthesis
7x + 3 * 3x + 3 * 6 = 194
7x + 9x + 18 = 194
subtract 18 from both sides of the equation
7x + 9x + 18 - 18 = 194 - 18
combine like terms
7x + 9x = 194 - 18
16x = 176
divide both sides of the equation by 16
16x/16 = 176/16
x = 176/16
x = 11
