Step-by-step explanation: Let
Let
y
be the total fee, and
x
the number of months.
Equation 1:
y
=
50
+
55
x
Equation 2:
y
=
200
+
45
x
Solve the system for
x
and
y
:
50
+
55
x
=
200
+
45
x
10
x
=
150
x
=
15
y
=
200
+
45
(
15
)
y
=
875
∴
The total amount paid to both gyms is equal after
15
months and will be
$
875
.
Hopefully this helps!
The first thing we must know in this case is that the distance is equal to the speed for time.
We have then:
For Chris:
d1 = 40 * t
For Amy:
d2 = 60 * (t-2)
The distance between both will be given by the hypotenuse of the rectangle triangle:
300 = root ((40 * t) ^ 2 + (60 * (t-2)) ^ 2)
Answer:
300 = root ((40 * t) ^ 2 + (60 * (t-2)) ^ 2)
option 3
The value of r is 26(approximately).
Answer:
1/3 is the y intercept
Step-by-step explanation:
f(x) = -2/9x + 1/3
This is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
-2/9 is the slope and 1/3 is the y intercept
