What is the relationship of the line 3x - y = 5 to the line 6x - 2y = -7?

Marta_Voda [28]

Answer:

Parallel

Step-by-step explanation:

in a Standard from equation, Ax+By=C

slope=-A/B

The slope of first line is -3/-1=3

The slope of second line is -6/-2=3

Same slopes but different C values mean they r parallel.

Suppose 80% of people enjoy swimming. Suppose 70% of people enjoy running.

Ede4ka [16]

Answer:

95%

Step-by-step explanation:

In this case we can apply a formula that tells us that:

# (AUB) = #A + #B - #AnB

Where A would be the ones who enjoy swimming and B would be the ones who enjoy running. AnB is the intersection of both sets, that is, those who enjoy doing both things, these values we have, if we replace them we have left:

#(AUB) = 80% + 70% - 55%

#(AUB) = 95%

Which means that 95% of people enjoy either swimming or running

In the year 1995, there were 1200 students at pine elementary school. In the year 2010 there were 1500 students. Find the rate o

AnnZ [28]

The rate of change from 1995 to 2010 is 20 students per year and the linear function that models the data will be: $y=20x-38700$

Explanation

In the year 1995, there were 1200 students and in the year 2010, there were 1500 students.

If $x$ represents the year and $y$ represents the number of students, then two points in form of $(x,y)$ will be: $(1995, 1200)$ and $(2010, 1500)$

So, the rate of change or slope = (change in value of y / change in value of x) $=\frac{1500-1200}{2010-1995}= \frac{300}{15}=20$

Now, plugging slope $(m)$ = 20 and first point $(x_{1}, y_{1}) =(1995,1200)$ into point slope form of linear equation $y-y_{1} =m(x-x_{1})$ , we will get.....
