Answer: D (12.42, 18.09)
Explanation:
For A, if you substitute them, 6.15+2.41(x because x always is first), you get 8.56 but y is 8.56. So therefore, A is wrong cause it is a solution but it asks us for an incorrect solution.
For B, if you substitute the numbers, 6.09+6.15 = 12.24 but y is 12.24 meaning 12.24 = 12.24 which is true. But the question asks us which is not true/a solution, so therefore, B is also wrong.
For C, if you substitute the numbers, you get 9.72+6.15 which is 15.87. Since y is 15.87, the substituted question is 15.87=15.87 which is true and therefore, C is also wrong since it is true but it is asking us for an incorrect solution.
We are then left with D, which is the correct option. I'm guessing you want an explanation for why it is correct. So if you substitute the numbers, you would get y = 12.42+6.15 and 12.42+6.15 is 18.57 but y is 18.09. So the equation is 18.09 = 18.57 which doesn't make sense and is false. Thus, D is the correct answer because it provides a set of numbers that is a false solution to the equation.
REMEMBER:
In an ordered pair, x is the first number while y is the second, so make sure you substitute correctly!
Brooke paints the outsides of the square walls and triangular ceilings of her treehouse. What area does she paint? Enter your answer in the box.
Answer:
216
Step-by-step explanation:
The formula of finding the surface is length * width * height or LxWxH.
Since everything is 6 you just multiply 6*6*6 which gives you 36*6 which gets you 216. You don't need the top 6 just to find the surface she will paint.

Roy hit 3 less than 4 times the number of balls during baseball practice than Joe did. Together the boys hit 52 balls. How many balls did Joe hit?
Answer:
Joe hit 11 balls Roy hit 41
Step-by-step explanation
Joe = J
Roy = 4J-3 (4times Joe less 3)
J+ 4J-3 = 52
5J -3 = 52
Add 3 on both sides
5J = 55
Divide both sides by 5
J= 11
Joe = 11
11X4 = 44
44-3 = 41
Roy 41
11+41 = 52
From 10:00 am to noon, the rise in temperature is 4 degrees C, and from 3:00 pm to 5:00 pm, the fall in temperature is 6 degrees C. What is the average rate of: a) The rise in temperature per hour? b) The fall in temperature per hour?
Answer:
(a) 2 degree celsius per hour
(b) 3 degree celsius per hour.
Step-by-step explanation:
From the question,
(a) Avearge rate of rise in temperature per hour(T') = Rise in temperature(T)/Time required for the rise(t).
T' = T/t.................... Euqation 1
Rise in temperature (T) = 4 degree celsius, t = 10.00 am to noon = 2 hours.
Substitute into equation 1
T' = 4/2
T' = 2 degree celsius per hour.
(b) Also,
Average rate of fall in temperature per hour (T') = Fall in temperature (T)/Time(t)
T' = T/t
Given: T = 6 degree celsius, t = 3:00 pm to 5:00 pm = 2 hours
T' = 6/2
T' = 3 degree celsius per hour

Answer:
Enoch is 30Martin is 15Step-by-step explanation:
The difference in ages remains the same over time. Enoch, at twice Martin's age, is still 15 years older. That means Martin is 15 and Enoch is 30.
HELPPP QUICK PLS I WOULD GIVE YOU THE BRAINIEST PLSSS HELPP MEEE BEFORE I HAVE A BREAKDOWN PLS What is the midpoint of a line segment with endpoints at (-4,15) and (22, 3)?
Answer:
(5.5, 12.5) OR (11/2, 25/2)
I would put in the decimal value as the answer, but of you like then you can add the fraction as an answer.
Step-by-step explanation:
We are given the endpoints (-4, 15) and (22, 3) to find the midpoint. In order to find the midpoint, we will use its formula.
Midpoint formula :- (x1 + x2 / 2, y1 + y2 / 2)
(x1 + x2 / 2, y1 + y2 / 2)
(-4 + 15 / 2, 22 + 3 / 2)
(11 / 2, 25 / 2) ---> (5.5, 12.5) Midpoint

Name the x-axis of symmetry for the parabola down below
Answer:
x = - 3
Step-by-step explanation:
The axis of symmetry is a vertical line passing through the vertex of the parabola with equation
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (- 3, - 6), (- 3, 4 ) with x- coordinates - 3
Then equation of axis of symmetry is x = - 3

Which of the following could be the graph of y = –xn where n is odd?
Answer:
Step-by-step explanation:
I think you meant y = -x^n, where ^ denotes exponentiation.
If n is odd, the graph begins in Quadrant II and decreases through the origin into Quadrant IV. This is true of -x, -x^3, -x^5, and so on.
