Answer:
Answer:
1. We have our function y = 15x + 35
a) Where the x represents the numbers of weeks since each week he is saving $15, which is the independent variable.
b) Where the y represents the total money he has, which is the dependent variable.
c) the slope is 15, as x increments, the slope goes up by 15.
d) The y-intercept is 35, because when x = 0, y = 35.
2. To create the table you have to find the value of y, knowing the values of x.
Using our function, when x = 0
y = 15(0) + 35
y = 0 + 35
y = 35
Using our function, when x = 1
y = 15(1) + 35
y = 15 + 35
y = 50
Using our function, when x = 2
y = 15(2) + 35
y = 30 + 35
y = 65
Using our function, when x = 3
y = 15(3) + 35
y = 45 + 35
y = 80
Using our function, when x = 4
y = 15(4) + 35
y = 60 + 35
y = 95
Using our function, when x = 5
y = 15(5) + 35
y = 75 + 35
y = 110
Yes, the table is proportional, because for each week, the value of his money is increasing by 15.
3. To create the graph, you can put the values of the table into the graph
And the graph is not proportional because to be proportional the relationship between “x” and “y” should be constant, meaning that, if “x” changes, “y” changes by the same percentage.
In this case our function has an intercept of 35 meaning that at week 0, he has $35 saved,
after a week: $50,
after two weeks: $65,
So, although is linear, is not proportional because when you double the weeks saved, you don't double the money saved.

Tickets to a school dance cost $6 in advance and $10 at the door. Student council (who is sponsoring the dance) wants to raise a minimum of $300 that evening in ticket sales alone.
Write an inequality to represent the scenario.
Answer:
The inequality that represents the scenario is: 6x+10y≥300.
Step-by-step explanation:
With the information provided, you can say that the amount raised in ticket sales would be equal to the result of multiplying the price per ticket sold in advance for the number of these tickets sold plus the result of multiplying the price per ticket sold at the door for the number of these tickets sold. Also, you know that the result of this has to be greater than or equal to 300 and the scenario can be expressed as:
6x+10y≥300, where
x is the amount of tickets sold in advance
y is the amount of tickets sold at the door

Here is the answer......
Answer:
2x² - 7x - 15
Step-by-step explanation:
Given
(2x + 3)(x - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(x - 5) + 3(x - 5) ← distribute parenthesis
= 2x² - 10x + 3x - 15 ← collect like terms
= 2x² - 7x - 15

What is the Rotational speed of someone standing in Helsinki, Finland located at 60°11' N and 24°56' E.? (radius of the earth is 3960 miles)
Answer:
515.5 mph
Step-by-step explanation:
I am fairly confident we are taking the same test/quiz thing right now and I figured this one out so here ya go:
60 degrees + 11 sec = 60.183 degrees
3960 * cos(60.183) = 1969 some number in relation to the distance to the poles
2 * pi * 1969 = 12371.8
12371.8 / 24 = 515.5mph
look up "How to Calculate Rotational Speed Around Earths Axis" on YT, video is by " VAM! Physics & Engineering" that is where I found the formula stuffs

The slope of the line below is -3. Use the coordinates of the labeled point to find a point-slope equation of the line.
Answer:
A
Step-by-step explanation:
Point slope is y-y1 = slope (x -x1)
Plug in the point you're given and you get
y + 7 = -3 (x - 5)
Hopefully this helps- let me know if you have any questions
Answer:
A. y + 7 = - 3 (x - 5)
Step-by-step explanation:
Given point is (5, - 7)
Slope of line (m) = - 3
Equation of line in point slope form is given as:
y - (-7) = - 3(x - 5)
y + 7 = - 3 (x - 5)

Answer:
30
Step-by-step explanation:
Based on the directions we know that both figures are similar, meaning there is a dilation factor changing the overall size of the figures. In order to find this dilation factor we can give it the value of x and multiply it to the various lengths of the smaller figure. Once this is done, we make these values equal to their the corresponding counterparts on the larger figure.
32x=40
x=5/4
Now that the dilation factor is found substitute its value for x
24(5/4)=30
Find the area of the figure, in square meters, to 1 decimal place.

describe how to use special product patterns to find 21^2
Answer:
21 x 21 = 441
Step-by-step explanation:
Whenever there is an exponent that is the many times you multiply the base by itself to.
Power is the result of multiplying two numbers together. The value of 21^2 is 441.
What is power?Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.
Given that 21 has a power of 2, therefore, 21 to the power 2 means that 2 should be multiplied by itself twice.
21^2
= 21²
= 21 × 21
= 441
Hence, the value of 21^2 is 441.

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
Answer:
Step-by-step explanation:
First choose two points on the line,
Let the points are A and B.
From point A to B we are moving downwards by (5 - 1 = 4 units)
Therefore, Rise = -4
Horizontal distance between A and B = 2 units
Therefore, Run = 2
Since, slope of a line = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Slope = [tex]\frac{-4}{2}[/tex]
= -2
