Two trains leave stations 324 miles apart at the same time and travel toward each other. One train travels at 100 miles per hour while the other travels at 80 miles per hour. How long will it take for the two trains to meet? Do not do any rounding.
Answer: The first train gets to the station in 3 hours 14 minutes, and 40 seconds if it is a consent speed of 100 mph The second train gets to the station in 4 hours and 3 minutes if it is a consent speed of 80 mph, so they would meet in 4 hours and 3 minutes.

how do you solve (5)/(18)-(x-2)/(9)<=(x-4)/(6)
Answer:
x ≥ [tex]\frac{21}{5}[/tex]
Step-by-step explanation:
Given
[tex]\frac{5}{18}[/tex] - [tex]\frac{x-2}{9}[/tex] ≤ [tex]\frac{x-4}{6}[/tex]
Multiply through by 18 ( the LCM of 18, 9 and 6 ) to clear the fractions
5 - 2(x - 2) ≤ 3(x - 4) ← distribute parenthesis and simplify
5 - 2x + 4 ≤ 3x - 12
9 - 2x ≤ 3x - 12 ( add 2x to both sides )
9 ≤ 5x - 12 ( add 12 to both sides )
21 ≤ 5x ( divide both sides by 5 )
[tex]\frac{21}{5}[/tex] ≤ x , that is
x ≥ [tex]\frac{21}{5}[/tex]

Find a point-slope form for the line with slope 1/5 and passing through the point (-4,-9).
Answer:
y + 9 = [tex]\frac{1}{5}[/tex](x + 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = [tex]\frac{1}{5}[/tex] and (a, b) = (- 4, - 9) , thus
y - (- 9) = [tex]\frac{1}{5}[/tex](x - (- 4) ) , that is
y + 9 = [tex]\frac{1}{5}[/tex](x + 4)
Write the linear equation in slope intercept form (-2,-4) and (-3,-3)

The weights, in ounces, of three different packages of cookies are listed below. Which list shows these weights in order from least to greatest? A 7.25, 7 1 7 , 7.7 B 7 1 7 , 7.25, 7.7, C 7.25, 7.7, 7 1 7 , D 7 1 7 , 7.7, 7.25
Answer: C. 7.25, 7.7, 7 1 7
Step-by-step explanation:
From the question, we are given the weight , in ounces, of three different packages of cookies and we are told to arrange them in ascending order that is, from the least to the greatest.
The least of the numbers is 7.25. After then we have 7.7 and the greatest is 717. Therefore this can be arranged as:
7.25, 7.7, 7 1 7
Therefore, the correct option is C.
9. y + 7 = 2(x + 5)
in standard form
Answer:
y=2x+3
Step-by-step explanation:
1. y+7=2(x+5) (rewrite the problem)
2. y+7=2x+10 (distribute the 2)
3. y=2x+3 (subtract 7 from both sides; 10-7=3)

Solving systems of equations graphicallyStep-by-step explanation:
In order for a systems of equations to have a solution set, the 2 graphs must intersect at at least 1 point. Here, we see that graphs 1 and 5 do not intersect each other at all.
Therefore, the rest of the graphs have solutions and #1 and #5 do no have any solutions.
For a United Way fund-raising dinner, a total of 245 tickets were sold. Adult tickets sold for $6.50, and child tickets sold for $3.00. If $1410.50 worth of tickets were sold, how many adult and child tickets were sold?
Answer:
Adults =193
children=52
Step-by-step explanation:
Step one:
let the number of tickets adults be x
and the number of tickets children be y
x+y=245--------1
6.5x+3y=1410.5---2
Step two:
solve the system of equation using substitution
x+y=245
x=245-y
put x=245-y in equation 2 we have
6.5(245-y)+3y=1410.5
1592.5-6.5y+3y=1410.5
-6y+3y=1410.5-1592.5
-3.5y=-182
y=182/3.5
y=52
put y=52 in x=245-y
x=245-52
x=193
What is the slope and y-intercept of the graph?
Slope:
y-intercept:
Answer:
Slope: 0
Y-intercept: 2
Step-by-step explanation:
Answer:
Slope = 0
Y-intercept = 2
Step-by-step explanation:
Hello!
The slope of the graph is how much the graph rises, compared to how much the graph runs.
As you can see here, the graph rises by 0, but runs infinetely, giving a slope of 0.
The y-intercept of the graph is where the graph intersects the y-axis.
The y-intercept here is 2, because it crosses the y-axis at (0,2).

17. Let f(x) = 2x2 + 5x + 6 and g(x) = 3x2 + 4x – 10.
a Find f(x) + g(x)
b. Find f(x) – g(x)
Step-by-step explanation:
f(x)+g(x)=(2x^2 + 5x +6) + (3x^2 +4x - 10)
Combine like terms
5x^2 + 9x -4
f(x)-g(x)=(2x^2 + 5x +6) - (3x^2 +4x - 10)
Distribute the negative
(2x^2 + 5x +6) + (-3x^2 -4x + 10)
Combine like terms
-x^2 +x +16
1. A set of weights includes a 5 lb barbell and 8 pairs of weight plates. Each pair, p,
weights 10 lbs. If x pair of weight plates are added to the barbell, the total weight of the
barbell in pounds can be represented by the function
f(x) = 10x + 5. What is a reasonable range of the function in this situation?
Answer:
5 <= y <= 85
Step-by-step explanation:
Since the lowest weight possible is 5lbs (just the barbell and no weights) the lowest point of the range is 5lbs (the y intercept when x = 0)
The highest weight possible is 85lbs since, there is only 8 pairs of weight plates (8 is the input value) and the pairs each weigh 10lbs (the slope of the graph) + 5lbs from the barbell (y-intercept).
Using the function given, if you input 8 as the x value, you get
85 = 10(8) + 5
So the highest value of the range is 85lbs, therefore the range is 5 <= y <= 85.

please help i will mark brainliest
Answer:
The coordinates of mage of L(5, 10) will be: (11, 3)
So, the 4th (last) option is correct.
Step-by-step explanation:
As we know that Translation means how much a point is moved to the left/right and up/down.
Given the translation maps the point J(1, 4) onto K(7, -3).As the x-coordinate of the image point K(7, -3) is 7 which is 6 units right to the original point J(1, 4).
Also, the y-coordinate of the image point K(7, -3) is -3 which is 7 units down to the original point J(1, 4)
so it means the translation basically implies that
(x, y) → (x + 6, y - 7)
Hence, the coordinate of the image of L(5, 10) can also be determined by
using the same rule.
(x, y) → (5 + 6, 10 - 7) = (11, 3)
Therefore, the coordinates of mage of L(5, 10) will be: (11, 3)
So, the 4th (last) option is correct.

===============================
Explanation:
Use the vertical line test. If it is at all possible to draw a single vertical line through more than one point on the relation curve, then the relation is not a function. This is because a function is only possible when any x input leads to exactly one y output.
So that's why graphs 1,2,3 are not functions, while graphs 4,5,6 are functions.
Figure 3 shows a sketch of part of the curve C with equation
Y=x(x+ 4)(x - 2)
The curve C crosses the x-axis at the origin and at the points A and B.
(a) Write down the x-coordinates of the points A and B.
Answer:
Step-by-step explanation:
because The curve C crosses the x-axis at the origin and at the points A and B => the x coordinates of A and B are the solution of the equation:
x(x + 4)(x - 2) = 0
<=> x = 0
x = -4
x = 2
because the x-coordinates of the points A and B aren't 0 and the x-coordinate
of A is a negative value
=> the x-coordinate of A is -4
the x-coordinate of B is 2
