Step-by-step explanation:
Jack drove to the train station and back. It
took two hours less time to get there than
it did to get back. The average speed on
the trip there was 40 km/h. The average
speed on the way back was 24 km/h. How
many hours did the trip there take?
Answer:
8hoursStep-by-step explanation:
let the time taken to get back be x
so that the time needed to go is (x-2)
we know that speed= distance/time
therefore the speed for the return is 24 km/h.
distance (return)= 24*x
distance (return)=24x
therefore the speed to the station is 40 km/h.
distance (return)= 40*(x-2)
distance (return)=40x-80
We know that the distance is the same
24x=40x-80
24x-40x=-80
16x=80
divide both sides by 16
x=5
the time taken to get back is x=5hours
the time taken to is x-2=(5-2)= 3hours
the total trip takes 3+5= 8hours
Solving systems by substituting
Explanation:
4x+3y=37
y=x-4
4x+3(x-4)=37
4x+3x-12=37
add 12 to both sides
7x=49
x=7
Now you use plug in x
4(7)+3y=37
28+3y=37
subtract 28 to both sides
3y=9
y=3
answer: x=7 and y=3

A can factory requires 2 sheets of metal to make 36 cans and 10 sheets of metal to make 180 cans. The proportionality constant between the number of cans made and the number of sheets of metal used is
.
Answer: 1 sheet of metal is equivalent to 18 cans
Step-by-step explanation:
If you divide 36/2 you get 18 and if you divide 180/10 you also get 18. So the proportionality of cans made to the number of sheets of metal used would be 1:18
Answer:
18
Step-by-step explanation:
1 sheet is equivalent to 18 cans it is simple just divide

[tex]\frac{16529}{500}[/tex]
Step-by-step explanation:
Convert to a mixed number by placing the numbers to the right of the decimal over 1000 . Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator.

1. Square of a Binomial
Symbols/Pattern:
(a + b)2 = a2 + 2ab + b2
(a - b)2 = 22 - 2ab + b2
In the pattern, if a is the first term and b is the last term, then the square
of a binomial consists of:
a) the square of the first term (a);
b) twice the product of the first and last terms (2ab); and
c) the square of the last term (54).
2. The product of the sum and difference of two terms
what is the equation of the following graph
Answer:
[tex]y=-(x-2)^2-3[/tex]
Step-by-step explanation:
Equation of the Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The graph provided in the question has two clear points:
The vertex, located at (2,-3)
The y-intercept, located at (0,-7)
Substituting the coordinates of the vertex, the equation of the function is:
[tex]y=a(x-2)^2-3[/tex]
The value of a will be determined by using the other point:
[tex]-7=a(0-2)^2-3[/tex]
Operating:
[tex]-7=a(4)-3[/tex]
[tex]4a=-4\Rightarrow a=-4/4[/tex]
Solving:
a=-1
The equation of the graph is:
[tex]y=-(x-2)^2-3[/tex]

Please help! Brainliest! How are the functions y = 2x2 and y = 2x2 + 7 related? How are their graphs related?
A. Each output for y = 2x2 + 7 is 7 less than the corresponding output of y = 2x2. The graph of y = 2x2 + 7 is the graph of y = 2x2 translated down 7 units.
B. Each output for y = 2x2 + 7 is 7 greater than the corresponding output of y = 2x2. The graph of y = 2x2 + 7 is the graph of y = 2x2 translated up 7 units.
Option B is correct.
We have the two equations -
[tex]y= 2x^{2}[/tex]
[tex]y=2x^{2} +7[/tex]
We have determine how are these functions related and how are their graphs related.
What type of conic section is represented by equation -y = [tex]$x^{2}[/tex] ?A parabola is represented by the equation y = [tex]$x^{2}[/tex].
According to the question, we have -
[tex]y= f(x) = 2x^{2}[/tex]
[tex]y=g(x)=2x^{2} +7[/tex]
Refer to the image attached for graphs.
Now -
g(x) - f(x) = [tex]2x^{2} +7-2x^{2}[/tex] = 7
Therefore - Each output for y = g(x) is greater than the corresponding output of y = f(x).
From the graph it is clear that the graph of y = g(x) is the graph of
y = f(x) translated up 7 units.
Hence, Option B is correct.
