Answer:
you already have x solved for so you plug 5-3y into the x in -6x and you get -6(5-3y)+5y=16
-30+18y+5y=16
-30+23y=16
23y=46
y=2
x=5-3(2)
x=5-6
x=-1

A set of data has 50 observations. How many classes would you recommend?
Answer:
6 classesStep-by-step explanation:
If k is the number of classes and n is the number of observations, then for number of classes we should select the smallest k such that 2^k > n.
We have n = 50 and:
2^5 = 32 < 502^6 = 64 > 50As per above described 2 to k rule, we are taking k = 6.
So 6 classes should be used.

What is the equation of the line in slope intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = -x
Step-by-step explanation:
(0, 0) and ( -100, 100)
m= (y2-y1)/(x2-x1)
m=(100-0)/( -100 -0)
m = 100/ -100
m = -1
y - y1 = m(x - x1)
y - 0 = -1(x - 0)
y - 0 = -x + 0
y = -x
-3x - 6+ (-1)

Step 1: Define Systems
y = -2x - 6
2x + y = 5
Step 2: Solve for x
Substitution
Substitute in y: 2x + (-2x - 6) = 5Combine like terms: -6 ≠ 5Here we see that -6 does not equal 5.
∴ the systems of equations has no solution.

A survey of teens showed that teens in Pittsburgh aged 12–17 spend 15.8 hours per week online. Teens in Miami/Ft. Lauderdale spends 14.2 hours per week online. Write and solve an additional equation to find the difference in time spent online by teens in these cities.
Answer:
1.6 hours
Step-by-step explanation:
Given that:
Time spent by Pittsburgh teens, p= 15. 8 hours
Time spent by Miami teens, m = 14.2 hours
The difference in time spent by the teens from these two cities is given by:
Time spent by Pittsburgh teens - Time spent by Miami teens
p - m
15.8 - 14.2 = 1.6 hours
