Two hikers walk on a trail in the direction of increasing mile marker numbers. Mandy starts at mile marker 1 and hikes at a rate of 2.5 miles per hour. At the same time, Rita starts at mile marker 2 and hikes at a rate of 3 miles per hour. The equation 2.5h+1=3h+2 represents the number of hours h it will take Mandy to catch up with Rita.
Let as consider, we need to find the number of hours h it will take Mandy to catch up with Rita.
Given:
The number of hours h it will take Mandy to catch up with Rita is represented by the equation
[tex]2.5h+1=3h+2[/tex]
To find:
The value of h.
Solution:
We have,
[tex]2.5h+1=3h+2[/tex]
Isolate the variable terms on one side.
[tex]2.5h-3h=-1+2[/tex]
[tex]-0.5h=1[/tex]
Divide both sides by -0.5.
[tex]h=\dfrac{1}{-0.5}[/tex]
[tex]h=-2[/tex]
We know that, time cannot be negative. So, [tex]h\neq -2[/tex].
The equation [tex]2.5h+1=3h+2[/tex] is not true for any positive value of h.
Therefore, Mandy will never catch up with Rita.

Answer:
1.)c=±√58
Step-by-step explanation:
According to Pythagorean theorem, square of the hypotenuse is equal to the sum of the squares of other two sides
a^2+b^2=c^2
Short sides-a and b
Long side=c
I will do number 1 for you as an example.
A=3
B=7
C=x
3^2+7^2=c^2
58=c^2
Dont forget to square 58
c=±√58

Find the point-slope equation for the line
that passes through the points (30, 2) and
(15, -28). Use the first point in your
equation
y - [?
l(x - [
Answer:
y-30=2(x-2)
Step-by-step explanation:
m=y2-y1/x2-x1
-28-2=(-30)
15-30=(-15)
-30/(-15)=2
m=2

Find 2 points that are 3 units from Point C and also share the same y-coordinate as Point C.
P.S its NOT -3,-5 -9,-5
Answer:
I'm guessing point C is (-6,-5)? But then, it would have to be the coordinates you listed, (-3,-5) and (-9,-5) because nothing else makes sense.
Or is it one of those questions that you give your own coordinates? I'm confused :'(
