Answer:
p = 11.2
Step-by-step explanation:
2.6(5.5p - 12.4) = 127.92
14.3p - 32.24 = 127.92
Add 32.24 to both sides
14.3p = 127.92 + 32.24
14.3p = 160.16
Divide both sides by 14.3 (the coefficient of p)
p = 11.2
Plan 1 = 29.94 + 0.10x
Plan 2 = 32.99 + 0.05x
Plan 1 = Plan 2
29.94 + 0.10x = 32.99 + 0.05x
0.10x - 0.05x = 32.99 - 29.94
0.05x = 3.05
0.05x/0.05 = 3.05/0.05
x = 61
61 MB of data is needed to make both plan equal.
to check: x = 61
29.94 + 0.10(61) = 32.99 + 0.05(61)
29.94 + 6.10 = 32.99 + 3.05
36.04 = 36.04
To find the slope intercept form, you plug in the slope and the points given and find whats missing
y=mx+b
slope is -2
given points are (4,-3)
-3=-2(4)+b (multiply -2 and 4)
-3=-8+b (add 8 to both sides)
5=b
so the equation for the slope intercept form would be
y=-2x+5
