Two trains leave towns 566 kilometers apart at the same time and travel toward each other. One train travels 11 km/h slower than the other. If they meet in 2 hours, what is the rate of each train?
Answer:
The speeds are 74 mph and 87 mph.
Step-by-step explanation:
Let x = speed of slower train
x + 13 = speed of faster train
The trains meet when the sum of the distances = 483
3x + 3(x+13) = 483
6x + 39 = 483
6x = 444
x = 74 mph
The speeds are 74 mph and 87 mph.

i dont know what the next sequence is
The next term of the sequence is 9
The terms of the sequence are given as:
64, 49, 36, 25, 16,...
When the above sequence is analyzed, we can see that:
Each term of the sequence is a perfect square
So, the sequence can be rewritten as:
8^2, 7^2, 6^2, 5^2, 4^2, ....
The next term would be 3^2.
The square of 3 is 9
i.e. 3^2 = 9
Hence, the next term of the sequence is 9

Both are correctStep-by-step explanation:
Paul used the following identities:
[tex]a^{-b}=1/a^b[/tex][tex]a^b*a^c=a^{b+c}[/tex]Anthony used the identity:
[tex]a^b/a^c= a^{b-c}[/tex]does the graph represent a function?

f(x) = -4x2 + 4x – 4
Find f(3)
F(3) occurs when x =3. So lets plug 3 into our equation.
[tex]f(3) = -4(3)^2 + 4(3)-4\\f(3) = -4(9) + 12- 4\\f(3) = -36 + 12- 4\\f(3)= -28[/tex]
F(3) = -28

consider the line y= -4/7x+2
Answer:
y=(7/4)x + 12, y=(-4/7)x -46/7
Step-by-step explanation:
first for the perpendicular line: we know the slope is the opposite reciprocal of -4/7, so m= 7/4. now we have y= 7/4 x +b. b is the y-intercept. to find b plug in the point (-8,-2). -2=(7/4)(-8) + b = -14+b so b=12. so the slope of the perpendicular line is y=(7/4)x + 12
parallel:
since the line is parallel the slope is -4/7. so we have y=(-4/7)x + b. next plug in the point (-8, -2) to find b: -2 = (-4/7)(-8) + b = 32/7 + b. so b= -46/7

~[tex]\large\boxed{\frak{Amphitrite1040:)}\ \bf \heartsuit}[/tex] A recipe calls for 1 1/8 cups of flower for every 3/4 cup of sugar used. How many cups of flour are needed for each cup of sugar used?
A 1 1/2
B 1 5/27
C 27/32
D 3/4
Answer: A
You could put this in a ratio of flour to sugar 9/8 : 3/4. If we need to find out how many cups of flour are required for each cup of sugar, then we’ll need to divide both sides by 3/4 to get to 1 cup of sugar so that we can find how many cups of flour are required for this amount. The flour is 9/8 cups which then gets divided by 3/4 and is 1/2 so this is our answer.

The graph below represents the function f(x) and the translated function g(x) .
If f(x) = x ^ 2 , which of the following functions could be an algebraic representation of g(x) ?
Answer: D. [tex]g(x) = (x-b)^2[/tex]
Explanation:
If we want to shift the curve some distance b to the right, then we'll need to replace x with x-b. What this effectively does is shift the xy axis itself b units to the left while the curve is fixed in place. This gives the illusion of the curve moving b units to the right.
Put another way: the old input x is updated to the new input x-b which is smaller by b units. This helps explain why the xy axis is shifted to the left this amount.
So that's how we go from [tex]f(x) = x^2[/tex] to [tex]g(x) = (x-b)^2[/tex]. You can think of it as [tex]g(x) = f(x-b) = (x-b)^2[/tex]
The original selling price was $154.30 The sale price was $127.92 What is the first step in finding the percent markdown?
Answer:
subtract the new price from the original price
Step-by-step explanation:
To find the percent markdown, first subtract the new price from the original price
154.30-127.92
26.38
Then divide by the original price
26.38/154.30
.170965651
Multiply by 100% to get the percent decrease
17.0965651% decrease

what is the distance between the coordinates (9, -2) and (9, 8) show your work on a coordinate grid pleas help mee
Answer:
10
Formular for finding distance between two points; (x2-x1)² + (y2-y1)² (all square root)
X1=9
X2=9
Y1=-2
Y2=8
Distance= (9-9)²+(-2-8)² (all square root)
=(0)²+(-10)² (all square root)
=0 + 100 (square root)
=100 square root

Express x2 + 4x - 7 in the form (x + a)? - b where a and b are integers.
Answer: (x+2)^2 -11
Step-by-step explanation:
X^2 +4x -7
Half the middle term, add it to x and put them into a bracket and square it
(X+2) ^2 -7
Square the second term to get 4 and then take that away from 7. (We do this because if we had the extra 4, our answer when’s we multiplied out of the brackets wouldn’t be x^2 +4x -7.)
(X+2)^2 -7 -4
Now simplify the whole numbers outside the bracket
(X+2) ^2 -11
A friend says that his grade on the test is 5 points lower than your grade. If your

-
or 5 - x?

Answer:
x-5.

If you did it the other way that would be like saying 5 minus your grade. That would be in the negatives unless you got a 5 or below on your grade. :)
Answer:
x-5
Step-by-step explanation:
The other way makes no sense saying 5 minus your grade I hope this helps and it's 5 less than your grade so your grade minus 5 ewuals your answer
