Answer:
-22
Step-by-step explanation:
Plug in 5 for x.
y = -3(5) - 7
y = -15 - 7
y = -22
The temperature in Quebec City was 5 degrees Celsius at 4 pm. By midnight, the temperature dropped 15 degrees. A number line has points negative 20, blank, A, B, 0, 5, C, blank, D. Which point is a representation of the colder midnight temperature in degrees Celsius?
Answer: Point A
Step-by-step explanation:
The temperature at midnight is;
= 5 - 15
= -10°C
Looking at the number line, one can surmise that the scale is in multiples of 5. This means that C is 10, B is -5 and A is -10.
With point A being -10°C, it represents the colder midnight temperature.
Answer:
Point A
Step-by-step explanation:
We know that the temperature dropped 15 degrees, and that it was initially of 5°C. So, by midnight, the temperature will be of -10°C (5-15=-10).
We also know that the distance between points is of 5°C. So, the point that we have to mark is point A, which represents -10°C.

How can you determine the sale price if you are given the regular price and the percent of markdown? (List the steps)
Answer:
The sale price is $34
Step-by-step explanation:
If we are given the regular price P and the markdown percentage r, we follow these steps:
1) Calculate the markdown or discount amount M.
M = P*r/100
2) Subtract it from the regular price:
S = P - M
S is the sale price.
Example: The regular price is $40 and the markdown percentage is 15%. Thus:
1) M = $40*15/100 = $6
2) S = $40 - $6 = $34
The sale price is $34

What is the slope of the line that passes through the points (4, 6)and (-16, -18)? Write your answer in the simplest form.
Answer:
6 / 5
I hope it is correct.
Step-by-step explanation:
Slope is (y2 - y1) / (x2 - x1)
choose two points: (4, 6) and (-16, -18)
(-18 - 6) / (-16 - 4)
-24 / -20 (simplify by -4)

Most staircases in use today have 9−inch treads and 8 12 −inch risers. What is the slope of a staircase with these measurements? Give your answer as a fraction or rounded to four decimal places, if necessary
Answer:
The value is [tex]m = 0.9022[/tex]
Step-by-step explanation:
From the question we are told that
The length of the treads is [tex]a = 9 \ inch[/tex]
The length of the risers is [tex]b = 8.12 \ inch[/tex]
Generally the slope of the staircase is
[tex]m = \frac{b}{a}[/tex]
=> [tex]m = \frac{8.12}{9}[/tex]
=> [tex]m = 0.9022[/tex]
Find the x-intercept and y-intercept
from the following linear equation:
-3x + 11y = 66
x - intercept (-22, [?])
y - intercept ([],[])
Answer:
x - intercept: (-22, 0)
y - intercept: (0, 11)
Step-by-step explanation:
Given the linear equation
-3x + 11y = 66
Determining the x-intercept
We know that the x-intercept can be computed by setting the value y=0 and solving for x.
substitute y = 0
-3x + 11y = 66
-3x + 11(0) = 66
-3x + 0 = 66
-3x = 66
Divide both sides by -3
-3x/-3 = 66/-3
x = -22
Thus, the ordered pair representing the x-intercept : (-22, 0)
Determining the y-intercept
We know that the y-intercept can be computed by setting the value x=0 and solving for y.
substitute x = 0
-3x + 11y = 66
-3(0) + 11y = 66
0 + 11y = 66
11y = 66
Divide both sides by 11
11y/11 = 66/6
y = 11
Thus, the ordered pair representing the y-intercept : (0, 11)
Therefore, we conclude that:
x - intercept: (-22, 0)
y - intercept: (0, 11)
Answer:
X=(-22,0)
Y=(0,6)

Answer: [tex]-p^2-(q+r)^2[/tex]
Work Shown:
I'm assuming your teacher wants you to factor as much as possible.
[tex]-p^2-q^2-r^2-2qr\\\\-p^2-q^2-2qr-r^2\\\\-p^2-(q^2+2qr+r^2)\\\\-p^2-(q+r)^2\\\\[/tex]
In the last step, I used the rule that [tex](a+b)^2 = a^2+2ab+b^2[/tex]
We cannot factor any further. If the first term was [tex]p^2[/tex] instead of [tex]-p^2[/tex], then we could use the difference of squares factoring rule.

Answer:
[0, ∞)
Step-by-step explanation:
The domain is the x values in a function. As you can see from the graph, the function touches zero (touching meaning the value zero is bracketed) and goes to infinity (infinity is parenthesis).
If a value is included it is bracketed. If it is not included it is used with parenthesis (infinity cannot be reached to it is used with parenthesis).

Your friend made $324 babysitting last year.This year she made 296% of what she made last year.How much more did your friend make this year?
Answer:
$635
Step-by-step explanation:
She made a total of $959 anad last year she made $324 so you then subtract the ammounts because the problem wants to know how much MORE she made.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
The more amount made this year is $635.04
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Your friend made $324 babysitting last year.
This year she made 296% of what she made last year.
This means,
The amount this year.
= 296/100 x 324
= $959.04
The difference in the amount.
= $959.04 - $324
= $635.04
The difference in the amount can also be calculated as,
= 296% - 100%
= 196% more this year.
So,
196% of $324
= 196/100 x 324
= $635.04
Thus,
The more amount made this year is $635.04

The graph shows the amount of money in Amy's bank account and her spending activity. Does the graph show a proportional relationship?
A. Yes, it is proportional because it has a constant rate of change.
B. No, it is not proportional because it has a constant rate of change.
C. Yes, it is proportional because it has a y-intercept.
D. No, it is not proportional because it has a y-intercept that is not zero.
Answer:
Option A:
Yes, it is proportional because it has a constant rate of change.
Step-by-step explanation:
One trick you can use to easily tell a proportional graph is that it follows a straight line. It does not matter whether the line slopes downwards or upwards. The fact that it is straight and not cured at any point, should hint you that the graph is proportional.
Proportional graphs have a constant rate of change. The value of the slope calculated when using any two (x, y) coordinates are the same for any point along the line.

one number is two more than triple a second number. Their sum is 30. what is the smaller number
Answer:
7
Step-by-step explanation:
We can solve this problem by making an equation.
Let x represent the second number
3x + 2 will be the first number because it is 2 more than triple x
This makes our equation:
3x + 2 + x = 30
Combine like terms
4x + 2 = 30
Subtract 2 from both sides
4x = 28
Divide both sides by 4
x = 7
The smaller number aka the second number is 7

An exterior angle of a triangle is equal to the sum of the two opposite interior angles.
so in first picture
1 is exterior angle of the triangle
it means that
1=2+3
so is evident that m 1 > m 2
in the second picture
1 is the exterior angle of the triangle
so
1=3+4
but 3=2 as alternate interior angles
definition:The Alternate Interior Angles Theorem states that if two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.
so is evident that m 1 > m 2
Answer:
see explanation
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(1)
∠ 1 is an exterior angle of the triangle, then
∠ 1 = ∠ 2 + ∠ 3
Thus ∠ 1 must be > ∠ 2
(2)
∠ 3 = ∠ 2 ( alternate angles )
∠ 1 is an exterior angle of the triangle, then
∠ 1 = ∠ 3 + ∠ 4 = ∠ 2 + ∠ 4
Thus ∠ 1 > ∠ 2

Pablo is riding his bike. The number of revolutions (turns) his wheels make varies directly with the distance he travels. See the graph below.(a) How many revolutions does Pablo make per foot of distance traveled? (b) What is the slope of the graph?
Answer:
A general line can be written as:
y = a*x + b
Where a is the slope, and b is the y-intercept.
if we know that the line passes through the points (x1, y1) and (x2, y2), the slope will be:
a = (y2 - y1)/(x2 - x1)
In this case, we can see that the line passes through the points (0,0) and (4,2) then the slope will be:
a = (2 - 0)/(4 - 0) = 2
Then the equation is:
y = 2*x + b
And because we have the point (0, 0), we know that the y-intercept is equal to zero, then the equation is:
y = 2*x
This means that Pablo does 2 revolutions per feet, and we already found that the slope of the equation is 2.
