-Log(1.4x10-3)= 2.85
The Log to be used here is the decimal one, not the neperian one.
No
y = 6
x = 19
Yes, 3+11=14
(0, -14)
No
y = 6
x = 19
Yes, 3+11=14
x = 3 and 1/3
(0, -14)
103
You should be able to look at this equation, or use the discriminant and know that there are no real roots.
2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
it equals 28
14 + 14 = 28
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
