Answer:
Mode-10
Mean-12
Range-13
Step-by-step explanation:
Mode is the most common which is 10
Mean is the averge so you add them all together then diviede based on how many numbers there are
Range is the difference between the smallest and biggest number so you just subtract. Biggest- smallest
12 subtracted by 33 divided by 4 equals 3.75
<span>y-3=-2(x-6)
y-3= -2x +12
y - 3 + 2x- 12 =0
2x+y =15,
Ax +By =C
A=2, B=1, C=15</span>
Substitution is plugging in a value for a variable to help solve the problem or equation.
<span>for example </span><span>"Substitute 5 into x" means plug 5 into x </span>
