Answer:
P(1.5, 3.5)
Step-by-step explanation:
We need to find the average of the x and y coordinates. We do this by adding the two values, then dividing by two:
P(x1 + x2/ 2, y1 + y2/2) = P(1 + 2/ 2, 2 + 5/ 2) = P(3/2, 7/2) = P(1.5, 3.5)
These are our coordinates!

Here is a system of equations:
-7x + 3y = -65
-7x + 10y = -135
Write an equation that results from subtracting the two equations.
Answers
Answer:
y = -10
Step-by-step explanation:
(-7x+3y) - (-7x +10y) =-65 -(-135)
-7x + 3y + 7x -10y = 70
-7y = 70
y = -10
The equation that results from subtracting - 7x + 3y = - 65 and
- 7x + 10y = - 135 is 7y = - 70.
What are simultaneous equations?We know two simultaneous equations have a unique solution when they intersect at a point,
when they are parallel they have no solution and when they are coinciding they have an infinite no. of solutions.
Given, a system of equations - 7x + 3y = - 65 and - 7x + 10y = - 135.
Subtracting the first equation from the second we get,
- 7x + 10y = - 135
(-) - 7x + 3y = - 65
_________________
Negative sign gets distributed
- 7x + 10y = - 135
+ 7x - 3y = + 65
_________________
7y = - 70
y = - 70/7
y = - 10.
So, the value of x is -7x +10×(-10) = - 135.
- 7x - 100 = - 135.
- 7x = - 135 + 100.
- 7x = - 35.
x = 7.

What distance would you travel in 2.5 hours if you are biking with the speed of 6.3 mph?
Answers
Answer:
15.75 milesStep-by-step explanation:
Step one:
given
time= 2.5 hours
speed= 6.3mph
Step two:
Required
Distance
we are given the speed in miles per hour, hence the distance will be in miles
we also know that the expression relating speed, distance and time is given as
speed= distance/time
thus
distance= speed*time
distance= 6.3*2.5
distance= 15.75 miles
By using expression for the speed, distance traveled by me in 2.5 hours will be
Given in the question,
Speed = 6.3 mphTime for travelling = 2.4 hoursExpression for the speed of an object is given by,
Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
Therefore, Distance = Speed × Time
By substituting the values of speed and the time in the expression,
Distance traveled = 6.3 × 2.5
= 15.75 miles
Therefore, distance traveled by me in 2.5 hours will be 15.75 miles.
