Answer:
186.55 mphStep-by-step explanation:
Let the speed of the plane be s
The speed of the plane in the same direction is
s + 12The speed of the plane against wind is
s - 12Time = distance/speed
455/(s + 12) = 400/(s - 12)Solving for s
400(s + 12) = 455(s - 12)400s + 400*12 = 455s - 455*12455s - 400s = (400 + 455)*1255s = 10260s = 10260/55s = 186.55 mph1) A soccer tournament has 4 teams, A, B, C and D. Each team will play the other 3 teams once. In each game the winning team earns 3 points, losing team 0 points and ties earn 1 point to each team. After these games are completed, the two teams with the most points will play in the championship. If teams earn the same number of points then the tie-breaker is whichever team scored more goals. Team C loses their first two games to A and B. Are they automatically eliminated or is there still a chance they could advance? Explain how they could still advance or why they are already eliminated.

Which statement correctly explains whether or not the values in the table represent a function of x
Answer:
Step-by-step explanation:
A relation is said to be a function when each input value (x-value) show a distinct output value (y-value).
From the table attached,
For input value x = 0, there are multiple values of output values (y = -2, -1, 0, 1, -2).
Therefore, data given in the table doesn't represent a function.
Answer: D
Step-by-step explanation: this is because of the input and output

3x = 27 + 3y
3x - 10y = 27
please explain how you got the answer.
Answer:
Hi there!
Your answer is:
Y= 0
X= 9
Step-by-step explanation:
3x=27+3y
3x-10y=27
Solve one of them for Y
I chose the first equation
3x=27+3y
-27
3x-27=3y
/3
x-9 = y
NOW, plug y in the second equation!
3x-10y=27
y= x-9
3x-10y=27
3x-10(x-9) = 27
Solve for x!
3x-10x+90 = 27
-7x + 90 =27
-90
-7x = -63
/-7
x= 9
FINALLY, plug back in x for y equation
y=x-9
x=9
y=9-9
y=0

Solve for x 10X^2+1=1001
Answer: 10
Step-by-step explanation:
Answer:
x = 10 and -10
Step-by-step explanation:
10x^2 +1 = 1001
Subtract one from each side
10x^2 = 1000
Divide 10 on each side
x^2 = 100
Take the square root on each side
x = 10 and -10

Where does the line y = 3x + 5 cross the y-axis?
A: at x=3
B: at x=5
C: at y =5
D: at y=3
Answer:
The answer is- At y = 5
Step-by-step explanation:
I got is correct on meh math test
The line y = 3x + 5 crosses the y-axis at y = 5. The correct answer would be an option (C).
What is y-Intercept?The y-intercept is defined as an intercept that is located at the y-axis of the plane, which is the location or coordinates from where the line crosses.
The equation is given in the question
y = 3x + 5
We have to determine the y-intercepts for the given line
To determine the y-intercept, substitute the value of x = 0 in the given equation
y = 3(0) + 5
y = 0 + 5
Apply the subtraction operation, and we get
y = 5
Thus, the line y = 3x + 5 cross the y-axis at y = 5.
Hence, the correct answer would be option (C).

Answer:
4
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 0, 4 ] , thus
f(b) = f(4) = - 4² + 8(4) - 4 = - 16 + 32 - 4 = 12
f(a) = f(0) = - 4 , then
average rate of change = [tex]\frac{12-(-4)}{4-0}[/tex] = [tex]\frac{12+4}{4}[/tex] = [tex]\frac{16}{4}[/tex] = 4

[tex]m = n + \frac{x}{p} \\ \\ \frac{x}{p} + n = m \\ \\ \frac{x}{p }= m - n \\ \\ x = m(p) - n(p) \\ [/tex]
Answer:
p(m - n) = x
Step-by-step explanation:
You want to "solve for x." To do this, subtract n from both sides (for the purpose of isolating the x/p term):
m - n + x/p
Next, multiply all terms by p:
p(m - n) = x

Kyle is making a frame for a rectangular piece of art. The length of the frame is 3 times the width, as shown below. A rectangle with a length of 3 x and height of x. If Kyle uses 18 feet of wood to make the frame, what is the length of the frame? Write the answer in decimal form.
Given :
A rectangle with a length of 3 x and height of x. If Kyle uses 18 feet of wood to make the frame.
To Find :
The length of the frame.
Solution :
We know, perimeter of the rectangle is given by :
[tex]P=2(l+b)\\\\P=2(3x+x)\\\\P=8x[/tex]
Now, it is given that 18 feet of wood is used.
So,
[tex]8x=18\\\\x = 2.25\ feet[/tex]
Therefore, length of frame is given by 3x = 6.75 feet.
Hence, this is the required solution.
Answer: A, 6.75
Step-by-step explanation: If the frame is 3 times the width and Kyle uses 18 feet them this the only correct option out of the other 3.

how do i find thedegree of a pollygon????
Answer:
Not sure what you mean, but I'm assuming you're referring to the sum of all the interior angles of a polygon. In that case:
Total sum of interior angles of a polygon ->
[tex]{180(n-2)[/tex]
However, if you are looking for the degrees of each interior angle, you must divide the total interior angle degrees by the amount of sides on the polygon, n
Degree of each interior angle of a polygon ->
[tex]\frac{180(n-2)}{n}[/tex]
In both cases, n represents the amount of sides the polygon has.

-10x= -20
/-10
x= 2
Answer:
x=2
Step-by-step explanation:
First you would subtract 2x from both sides so. Then you will add 15 so you can isolate your x onto your right side. Then you will divide both sides by 10 to get x=2.
