ANSWER

EXPLANATION
We were given that

varies directly as

We can write this mathematically as,

This implies that,

where k is the constant of variation.

This implies that,


The equation becomes

When

Answer:
Point slope: y+4=4(x-3)
Slope-intercept: y=4x-16
Step-by-step explanation:
1. Use the slope formula to find the slope.
y2-y1/x2-x1
8--4/6-3 = 12/3
Slope is 4
2. Use the slope and one of the coordinates to put the equation in point-slope form.
Point slope form: y-y1=m(x-x1)
y+4=4(x-3)
3. Distribute and simplify to put it in slope-intercept form.
y+4=4x-12
y=4x-16
Answer:
y = 175. x = 300. Disney vacation is 300 sold. Cars sold were 175.
Step-by-step explanation:
They want to raise $80,000. There are a total of 475 tickets.
150x + 200y (Disney Vacation + Win a car) = 80,000
x + y = 475.
__
y=475-x
150x+200(475-x)=80000
150x+95,000-200x=80,000.
-50x + 95,000 = 80,000.
-50x = -15,000
x = 300.
Disney vacation is 300 sold.
300 + y = 475.
y = 175.
Cars sold were 175.
