Answer:
x = 6, y = -2
Step-by-step explanation:
24/4 = 6
x = 6
= (5x6)+8y=14
= 8y = 14 -30
8y = -16
y = -16/8
y = -2
Check: 5x6+8x-2= 14
Answer:
2.7 x 5.2 = 14.04
Step-by-step explanation:
This is an exponential function.
If x = 0, 2^x = 2^0 = 1. The beginning value of 2^x is 1 and the beginning value of 51*2^x is 51.
Make a table and graph the points:
x y=51*2^x point (x,y)
-- --------------- ---------------
0 51 (0,51)
2 51*2^2 = 51(4) = 204 (2,204) and so on.
The graph shows up in both Quadrants I and II. Its y-intercept is (0,51). Its slope is always positive.
0.1 decrease in 15 minutes
unit rate is 0.1 / 15 = 0.00667
Temperature is decreasing by 0.00667 degrees Celsius per minute
