Answer:
(1,4)
Step-by-step explanation:
2x-3y=-10
y=4x
Since the y is already isolated, you can use substitution to find the answer to this equation. Simply replace any y values in the first equation with 4x:
2x-3(4x)=-10
2x-12x=-10
-10x=-10
x=1
y=4(1)=4
Hope this helps!

Answer:
Use normalcdf ( 1.75, 1.85, 1.84, 0.07 )
Doc and Marty should have laptimes between 1.75 and 1.85 approximately 45.75% of the time.
Step-by-step explanation:
Answer:
4,398,046,510,000 or 4^21
Step-by-step explanation:
If you need to solve:
(4^3)^7
4^3= 64
64^7= 4.39804651×10^12 or 4,398,046,510,000
If you just need the exponents answer:
You multiply exponents so the answer would be 4^21
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
