Answer: The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
Step-by-step explanation:
Answer: It is a continuous random variable.
The amount of rain is a continuous random variable because it can take on all of the numbers on a number line.
For example, the actual amount of rain in April could be 1 inch. Or 1.4 inches. Or 1.45 inches. Or 1.452020980234 inches. There are an infinite possibilities for the amount of rainfall.
Answer:
The answer is A. (4x²+3)(x+2)
Step-by-step explanation:
If u multiply (4x²+3) by (x+2), u get 4x^3+8x^2+3x+6
Answer:
Okay! It should be the 3 one.
-2(3)+30=24
Step-by-step explanation:
Multiply both sides by 19 to get w=171
