if i walk 120 meters per minute slower than i cycle. my cycling speed is 3 times faster than my walking. What is my walking speed. meters per minute
Answer:
His walking speed is 60 meters per minute.
Step-by-step explanation:
Given that the person walks 120 meters per minute slower than he cycles, and his cycling speed is 3 times faster than his walking, in order to known his walking speed in meter per minute, the following logical reasoning has to be made:
The person walks 120 meters per minute slower than he rides a bicycle, and in turn, rides a bicycle three times faster than he walks. Therefore, those 120 meters per minute is 2/3 of his speed on a bicycle, which makes up the remaining third with the speed at which he walks. Thus, since 120/2 is 60, and 60 x 3 is 180, the person walks at 60 meters per minute, and bicycles at 180 meters per minute.
Sonya makes a pattern of values for x and a pattern of values for y. Which
ordered pair continues the patterns and has an x-value of 6?
Answer: (6, 9)
Step-by-step explanation:
We have the pairs:
x y
0 0
2 3
4 6
These can be written as points (0, 0), (2, 3) and (4, 6)
This seems to be a linear relationship:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
In the cases where the point (0, 0) belongs to the graph, we have a proportional relationship, which is written as:
y = k*x
In this case we have that point, then this is a proportional relationship.
Now we could just replace the values of one of the points (not the (0,0) point) in the equation in order to find the value of x.
If we use the point (2, 3) we get:
y = 3
x = 2
then:
3 = k*2
3/2 = k
Then the relationship is:
y = (3/2)*x
Now we want to know the ordered pair such that x = 6, then we just eed to replace x by 6 in the above equation:
y = (3/2)*6 = 9
Then we have x = 6 and y = 9
The correct option is (6, 9)

A parabola intersects the x-axis at x=−4 and x=8.
What is the equation for the axis of symmetry?
A. x = - 4 B. x = 0 C. x = 2 D. x = 6
Answer:
C. x=2
Step-by-step explanation:
The axis of symmetry divides the parabola into two equal parts. FRom point x=-4 to x=8, the difference is 12 units and the centre is6 units on each side. Using a number line, the axis of symmetry is at point x=2
Answer:
C. x=2
Step-by-step explanation:
(x+4)(x-8) = x²-4x-32 = (x-2)² - 36

Carly wants to fly to Canada, rent a car, and drive 568 miles to visit her sister in a truck that gets 21 miles per gallon. If gas costs $1.02 per liter, how much will the road trip cost her? There are 3.79 liters in 1 gallon. Round your answer to the nearest cent.
Answer:
$104.56
Step-by-step explanation:
The computation of the cost of the road trip as follows:
The total number of gallons required is
= 568 ÷ 21 miles
= 27.05 gallons.
Now
the cost of one gallon is
= 3.79 × 1.02
= $3.8658
So, the cost of the road trip is
= 27.05 × 3.8658
= $104.56

X+y=15-2x+5y=-2 solve your systems of solutions and record your answer as an ordered pair
Answer:
x = 11 and y = 4
Step-by-step explanation:
Given equations are :
x+y=15 ...(1)
-2x+5y=-2 ...(2)
We need to solve the systems of equations.
Multiply equation (1) by 2.
2x+2y=30 ...(3)
Adding equation (2) and (3).
-2x+5y+2x+2y = -2+30
7y = 28
y = 4
Put the value of y in equation (1).
x+4=15
x = 11
So, the solution of the given equations are x = 11 and y = 4.

The graph of a function f is given use the graph to estimate all the local maximum and minimum values as a function and the value of x at which each occurs then the intervals the function is increasing and the function is decreasing I figured out the increasing is negative 9 and 0 and 6 and infinity
Answer:
The function f is graphed.
f is an even function as it has U- form.
As per the graph there is one local maximum at (0, 4) and one local minimum at (6, 1).
The global minimum is (-9, -2) and the global maximum is infinity.
The minimum and maximums are the borders of the increasing or decreasing intervals.
