Is (6, 34) the solution to the system below?
y = 5x + 4 and x + y = 40
Circle your final answer. SHOW WORK as mathematical proof.
Answer:
Yes
Step-by-step explanation:
y = 5x + 4
x + y = 40
x = 6
y = 34
34 = 5(6) + 4
34 = 30 + 4
34 = 34
34 + 6 = 40

5x+7=7(x+1)-2x
Answer:
5x + 7 = 5x + 7
Step-by-step explanation:
5x + 7 = 7(x + 1) - 2x
5x + 7 = 7x + 7 - 2x
5x + 7 = 5x + 7
5x + 7 = 5x + 7

The spinner below shows 10 equally sized slices. Charmaine spun the dial 40 times and got the following results.
Outcome Grey White Black
Number of Spins 25 9 6
Fill in the table below. Round your answers to the nearest thousandth.
(a) From Charmaine's results, compute the experimental probability of landing on white.
(b) Assuming that the spinner is fair, compute the theoretical probability of landing on white.
(c) Assuming that the spinner is fair, choose the statement below that is true:
1. The experimental and theoretical probabilities must always be equal.
2. As the number of spins increases, we expect the experimental and theoretical probabilities to become closer, though they might not be equal.
3. As the number of spins increases, we expect the experimental and theoretical probabilities to become farther apart.
Answer:
9/40= 0.225 (experimental probability for white)
(b) because the spinner has 10 sections but there has only been 3 outcomes. If the spinner has 3 sections the changes of white would be 0.333.
2. Is correct, the more times you spin the closer you’ll get to the theoretical probability.

Answer:
273.25 feet2
Step-by-step explanation:
Daniela can only place the grass in the shaded areas and not the white areas so you want to start by finding the area of the full circle (12.5ft*25ft) and then subtracting the two equal quarter circles on the left and right corners, this can be done by using the radius given (5ft) and finding the area of what the full circle would have been 3.14*(5^2) which is equal too 78.5 (I got 3.14 from pi) and then dividing 78.5 by 4 to find the area of the quarter circle which is 19.625. since there are two quarter circles you multiply 19.625 by 2 and finally subtract your original recttangul by the two quarter circles 312.5(original rectangul)-39.25(the two quarter circles) giving you 273.25 feet2. hope that makes sense
Law of Sines Round to the nearest degree.
Answer:
Step-by-step explanation:
recall law of Sines Sin(A) /a = Sin(B) / b
for this question
F = A = 105 and a = 37
E = B and b = 28
then plug those into our law of Sines equations
Sin(105) / 37 = Sin(B) / 28
0.025846 = Sin(B) / 28
28 * 0.025846 = Sin(B)
0.72369 = Sin(B)
arcSin(0.72369) = arcSin ( Sin ( B ) )
46.3599 = B
E = 46° ( rounded to the nearest degree)

Solve In(x – 2) – In(x – 3) = 1. Round your answer to three decimal places.
#natural logarithm #algebra 2
Condene the logarithms on the left side by applying the property, ln(a) - ln(b) = ln(a / b):
ln(x - 2) - ln(x - 3) = 1
→ ln((x - 2) / (x - 3)) = 1
Now take the exponential of both sides:
exp(ln((x - 2) / (x - 3))) = exp(1)
(x - 2) / (x - 3) = e
Solve for x :
x - 2 = e (x - 3)
x - 2 = e x - 3e
x - e x = 2 - 3e
(1 - e) x = 2 - 3e
x = (2 - 3e) / (1 - e) ≈ 3.582
Write an equivalent expression to 2 + 3 + 5 + 6 by combining like terms.
Answer:
answers are below
Step-by-step explanation:
(2+3) + (5+6)
(5) + (11)
equivalent expression: 5 + 11
is this the actual expression though? because in this case, i think that your expression should 2x + 3 + 5x + 6 and not what you mentioned.
however, if that is the case then your answer would be:
7x + 9
In the past month, Lashonda rented 7 video games and 1 DVD. The rental price for each video game was $2.90The rental price for the DVD was $3.50. What is the total amount that Lashonda spent on video game and DVD rentals in the past month
Answer:
Lashonda spent $23.8 all together.
Step-by-step explanation:
We solve this by multiplying how many videogames she bought with how much they cost plus how much that one DVD cost.
7 x 2.90 + 3.50
This equals
23.8

After Dan makes a basket, Josephine claims she can find the amount of time the ball was in the air (from the time it leave's Dan's hand to the time it enters the basket),
Josephine says she can do this by using Dan's equation (1) = -1649 +18 + 8) and setting the equation equal to zero. Dan doesn't think Josephine's thinking is correct.
Who do you agree with?
Explain your reasoning using mathematical evidence.
Answer:
Step-by-step explanation:
The function is to blurry to see but you would not set the height function equal to zero. Instead h should be set to the height of the basket. The time elapsed would be the second time the ball was at the height of the basket. If I guess what the function is as
-16t^2+18t+8=10
-16t^2+18t-2=0
-16t^2+16t+2t-2=0
-16t(t-1)+2(t-1)=0
(-16t+2)(t-1)=0
So the ball is at 10ft at 0.125s and 1s. So it enters the hoop after 1 second. Of course this is dependent on if I guessed at the correct equation from the picture.
