Answer:
Slope in fraction form = 5/2
Slope in decimal form = 2.5
========================================================
Work Shown:
m = (y2-y1)/(x2-x1)
m = (-5-10)/(-2-4)
m = (-15)/(-6)
m = (-3*5)/(-3*2)
m = 5/2 slope in fraction form
m = 2.5 slope in decimal form
-----------------
Explanation:
The first step is the slope formula where (x1,y1) and (x2,y2) are the two points the line goes through.
I used (x1,y1) = (4,10) and (x2,y2) = (-2,-5)
The slope formula basically says "subtract the y values, then subtract the x values in the same order. Then divide the two differences".
Or you can think of it as
slope = rise/run
rise = y2-y1 = change in y
run = x2-x1 = change in x
Answer:I think x is 43 not sure tho
Step-by-step explanation:
249 children and 394 adults swam at the public pool.
Step-by-step explanation:
Number of people swam at pool = 643
Receipts = $1161.50
Cost for one child = $1.50
Cost for one adult = $2.00
Let,
x be the number of children
y be the number of adults
According to given statement;
x+y=643 Eqn 1
1.50x+2.00y = 1161.50 Eqn 2
Multiplying Eqn 1 by 2
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 0.5
Putting x=249 in Eqn 1
249 children and 394 adults swam at the public pool.

Ok so total distance is 22 cm. And 2 sides r equal and third side is 6cm. So we can currently put this in the equation: 22=x+x+6 (x represents the two sides) they can be the same variable since they are equal too.
Steps for solving the equation: 22=2x+6
16=2x
x=8.
The two equal lengths of the triangle are 8 cm long.
