42 = 3x - 15 Since you know x = 19, you can plug in 19 for "x" in the equation
42 = 3(19) - 15
42 = 57 - 15
42 = 42 This is the solution
x = 19 is the solution because 3 • 19 – 15 = 57 – 15 = 42. (3rd choice)

Answer:
yeah but it depends on what your measuring
have a good day :)
Step-by-step explanation:
Answer:
a) 0
b) -5
Step-by-step explanation:
We want to find f(x) = -4
This means find the value of x where y=-4
The value of x where y=-4 is x=0
Then find f(2)
This means find the value of y when x =2
The value of y when x=2 is -5
<span>The square root of (a * b) is equal to (the square root of a) * (the square root of b)
-32 equals 32 * -1; therefore, the square root of -32 equals the square root of 32 times the square root of -1.
32 equals 16 * 2; the square root of 32 equals ? 16 * ?2 equals 4* ?2
The square root of -1 is i.
Therefore (2? -32) equals 2 * 4 * i * ?2 = 8i?2</span>
