Answer:
y = 29
Step-by-step explanation:
y = (3x)2 + 17
y = (3(2))2 + 17
y = (6)2 + 17
y = 12 + 17
y = 29
They are equal because if you divide 4÷1.0 your answer would be 0.4
|3x+1|=4 : x=−

|3x+1|=4
Aplicar las propiedades de los valores absolutos: Pi |u| = a, a>0 entonces u = a or u = −a

3x+1=−4 or 3x+1=4
The mean is 87 and median is 86.
<h3>What is mean and median?</h3>
The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list.
The median is the middle value in a list ordered from smallest to largest.
Given:
79, 91, 93, 85, 86, and 88
So,
79+85+86+88+91+93/6 = 87
and, the median
79, 85, 86, 88, 91, 93
median = 86
