Answer:
6x^2 + 15x - 13
Step-by-step explanation:
Combine Like Terms
9x^2 - 3x^2 = 6x^2
7x - (-8x) = 15x
-6 - 7 = 13
Write Equation

Robert was using a bucket that holds 243.5 ounces (oz) of water when full. The bucket loses 0.3 oz of water per second. After 20 seconds, Robert noticed the leak and plugged the leak. How much water, in ounces, remained in the bucket?
-Note from user: Hello! Could you please help me? I want to learn how to do this in the future so it would be appreciated if u add an explanation to your answer, thanks and please respond before 11:59)
Answer:
237.5
Step-by-step explanation:
Since the bucket loses 0.3 oz of water per second, and 20 secs passed, you would have to multiply 0.3 and 20 to find out how much water leaked. And 0.3x20=6, so then, we would have to subtract 234.5 and 6 to find out how much water there is left in the bucket. 234.5-6=237.5
So 237.5 is your answer

Tyler belongs to a fitness club at a community centre. The graph below represents the relationship between the number of times he visited the club and his total monthly cost. What type of variation is this relationship, and what is the initial value? *
#1 Direct Variation, and initial value is 0
#2 Partial Variation, and initial value is 0
#3 Direct Variation, and initial value is 20
#4 Partial Variation, and initial value is 20
Answer:
#3
Step-by-step explanation:
The type of variation in this relationship is direct variation, and the initial value is 20.
What is the linear relationship?
A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.
The given graph represents the relationship between the number of times he visited the club and his total monthly cost.
As per the given graph, we can conclude as follows:
The type of variation in this relationship is a direct variation because the points are increasing, and the initial value is 20 because the coordinate of the initial point is (0, 20).
Hence, the correct answer would be option (C).

5x + 3 = 3x + 9 what is the value of x
Answer:
x = 3
Step-by-step explanation:
5x + 3 = 3x + 9
subtract 3 on both sides (cancels out 3) (inverse operation)
5x = 3x + 6
subtract 3x on both sides (cancels out 3x) (inverse operation)
2x = 6
divide both sides by 2 (isolates x) (simplifies)
x = 3
5x-2y=30

(8,_)
Answer:
(8,5)
Step-by-step explanation:
x=8,
5(8)-2y=30
40-2y=30
40-30=2y
10=2y
y=10/2
y=5
Answer:
y=5
Step-by-step explanation:
If x=8, you plug it in and the equation is 5(8)-2y=30. If you solve it further, it is 40-2y=30. If you ignore the 2y for now, 40 minus what equals 30? The answer is 10 so you look at 2y and determine how you can multiply 2 to get 10. The answer is 5 so the full equation is 40-10=30.

Another term to represent Unit Rate is?
Constant of Proportionality
Slope
Rate of Change All of the Above
None of the Above
Answer:
All of the above.
Step-by-step explanation:
In a graph, the unit rate gives us the change in y for a unit change in x. That is, the unit rate is the rate of change in y when the change in x is 1.
Therefore, the unit rate is the same as the rate of change.
And the rate of change is synonymous with the slope.
The constant of proportionality is simply the slope/rate of change for proportional equations.
Therefore, the constant of proportionality is also another word for the unit rate.
Our answer is hence all of the above.

Identify an equation in point-slope form for the line perpendicular to
y=-1x +11 that passes through (4, -8).
O A. y +8 = 2(x-4)
B. y - 4 = 2(x+8)
O C. y+8 = {(x-
-4)
O D. 7-8 = {(x + 4)
Answer:
C
Step-by-step explanation:
Perpendicular lines have the exact opposite slope of the other equation.
So the slope will be x or 1x. Plug in
-8 = 1(4) + b (b represents y-intercept) like y=mx+b
-8 = 4 + b (subtract 4 on both sides)
-12 = b
The equation is y = x - 12
C
solve
y + 8 = x - 4 (subtract 8 on both sides)
y = x - 12

2. Net gain of 6 yards
3. 7684 ft
Step-by-step explanation:
1.
Walmart’s stock price started at $70. It went up by $2, then went down $4
Final stock = [tex]70+2-4=68[/tex]
2.
A football team gains 5 yards, then loses 2 yards, then gain another 6 yards, then loses 3 yards

At East Middle School, 25% of the 60 students Mrs. White teaches buy their lunches in the cafeteria. How many students purchase their lunch in the cafeteria?
Answer:
15
Step-by-step explanation:
Whenever you see 25% of something, divide the original number by four. Because 25x4=100, you can use this equation. 25% of something is always your original number divided by four. In this case, the original number is 60. 60 divided by four is 15.

Write an equation for the n th term of the arithmetic seqeuence. Then find a 10
-6, – 9. - 12. - 15, .
Answer:
3n-9
Step-by-step explanation:
Each term increases by 3, so there n should be multiplied by 3.
If the first term (or when n = 1) is -6 and we have 3n, we need to subtract 9 to get -6. This also works for the other terms in the sequence.
The 10th term of the sequence would then be:
3(10)-9
21
