Answer:
<h2>$32</h2>
Step-by-step explanation:
Step one:
Given that membership is $9 and the cost per visit is $1
let the number of visits be x
and the total cost be y
the total cost for the situation is modeled as
y=mx+c-----equation of a line
Step two:
given that x=23, we can solve for the totals cost as
by substituting we have
y=1*23+9
y=23+9
y=32
<u>The total cost for 23 visits is $32</u>
Answer:
let this happens after t hours
so
80t + 60t = 392
140 t = 392
t = 392/140
=2.8 hours
Perpendicular has slope that multiplies to -1
y=mx+b
m=slope
y=-1x+11
-1 times what=-1?
what=1
y=x+b
find b
given
(-2,3)
(x,y)
inpus -2 for x and 3 for y
solve for b
3=1(-2)+b
3=-2+b
add 2 to both sides
5=b
y=x+5 is equation
not listed, but the choices are all wrong
A rectangle has four sides, two equal to the width and two equal to the length. So, the perimeter is
If we know that the width is 5, and the perimeter is 125, we have
In your case, the unkown is called x, but the concept is the same:
where x is the length of the rectangle.
