Answer:

Step-by-step explanation:

The line is parallel to the x axis, so its slope is 0

m = 0

the y intercept is -2.5

the line doesn’t intercept the x axis because is parallel to it

SCORPION-xisa [38]

Answer:

9/10

1/2+2/5

Since these fractions have different denominators, we need to find the least common multiple of the denominators.The least common multiple of 2 and 5 is 10, so we need to multiply to make each of the denominators = 10

1/2 ∗ 5/5 = 5/10

5/2∗ 2/2= 4/10

Since these fractions have the same denominator, we can just add the numerators

5/10+ 4/10 = 9/10

5 % of 170 is what number?

Darina [25.2K]

Answer: 3400

Step-by-step explanation:

We have, 5% × x = 170

or,

100

× x = 170

Multiplying both sides by 100 and dividing both sides by 5,

we have x = 170 ×

100

x = 3400

If you are using a calculator, simply enter 170×100÷5, which will give you the answer.

x=\frac{3}{10}y\\
y=\frac{5}{9}z \\z=32\frac{2}{5}\\\\\y=\frac{5}{9}*32\frac{2}{5}=\frac{5}{9}*\frac{162}{5}=18\\\\
x=\frac{3}{10}*18=5,4\\\\

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.....

$y-1200=20(x-1995)\\ \\ y-1200=20x-39900\\ \\ y= 20x-39900+1200\\ \\ y= 20x-38700$
