Answer:

y=2/3x-1

Step-by-step explanation:

First you have to find the slope:

(y2-y1)/(x2-x1)

I chose the points (0, -1) and (1.5, 0) and plugged in the numbers to get:

(0-(-1))/(1.5-0)=1/1.5=2/3

So the slope is 2/3.

The y intercept is -1 because that's where the line crosses the y-axis.

The slope intercept form is y=mx+b

m being the slope and b being the y intercept.

After plugging in: y=2/3x-1

Find f(0), if not supplied, and then find the equation of the given linear function.

My name is Ann [436]

Answer:

Part 1) $f(0)=2$

Part 2) $f(x)=3x+2$

Step-by-step explanation:

Part 1) Find f(0)

we know that

Looking at the data in the table

When the value of x increases by 1 unit, the value of y increases by 3 units

therefore

When the value of x decreases by 1 unit from 1 to 0, the value of y would decreases 3 units from 5 to 2

thus

$f(0)=2$

This value represent the y-intercept

Part 2) Find the equation of the given linear

Find the slope

take the points (1,5) and (2,8)

$m=(8-5)/(2-1)=3$

The equation of the line in slope intercept form is equal to

$f(x)=mx+b$

we have

$m=3\\b=2$

substitute

$f(x)=3x+2$

Larissa argued that since log2(2) = 1 and log2(4) = 2, then it must be true that log2(3) = 1.5. Is she correct?

mestny [16]

Answer:

$2^{1.5} = 2.8284$ . This means that Larissa is not correct.

Step-by-step explanation:

To solve logarithms, we have to consider the following:

$\log_{a}(b)$ = c means that $a^{c} = b$ .

So, for example:

$log_{2}(2) = 1$ because $2^{1} = 2$ .

$log_{2}(4) = 2$ because $2^{2} = 4$ .

If $2^{1.5} = 3$ , then Larissa is correct. However, $2^{1.5} = 2.8284$ . This means that Larissa is not correct.

Joan went to the bookstore. At

kiruha [24]

Answer:

$\frac{1}{4}$ of the books in the book store are mystery fiction books.

Step-by-step explanation:

Let x represent all the books in the books store.

Then, the fraction of books that are fiction books is $\frac{3}{4}x$

We have that; $\frac{1}{3}$ of the fiction books are mystery books.

The fraction of the books at the bookstore that are mystery fiction books is $\frac{1}{3}\times \frac{3}{4}x=\frac{1}{4}x$ .

Therefore $\frac{1}{4}$ of the books in the bookstore are mystery fiction books.
