Answer:
- If x=0 , then f(0)=2
- If f(x)=0 , then x = -1
Step-by-step explanation:
First lets assume that the y axis is called the<em> ordinate axis </em>and the x axis is the <em>abscissa axis</em>
Then:
- The first question asks for the y value in the <em>ordinate axi</em>s that corresponds to the x = 0 value. To begin:
You must start to locate the x=0 value on the abscissa axis, its located in the center of the axis.
Then you start for searching the y value that the curve takes when it passes through the ordinate axis, this correspond to the value of the function f(x) on x=0. The value according to the graph is y=2.
Then , you located the point (0,f(0))=(0,2).
- The second question asks for the x value in the abscissa axis that corresponds to the f(x)=y=0 value. To begin this, you start the other way around:
You must locate the y=0 value on the ordinate axis, its also located in the center of the axis.
Then you start for searching the x value that the function needs to take the y=0 value. According to the graph the value of x that the function needs is x = -1
Then, you located the point where f(x)=y=0, its (-1,0).

Answer:
He bought 17 books.
Step-by-step explanation:
Given that:
Total money spent = $89
Cost of each book = $5
Shipping price = $4
We have to find, Total number of books
So if the number of books be represented by b, the equation will become:
Cost of one book * total number of books + shipping price = total money
Putting values we get:
5*b + 4 = $89
By simplifying:
5*b = 89 - 4
5*b = 85
Dividing both sides by 5 we get:
b = 17
So the total number of books bought is 17.

Answer:
240
Step-by-step explanation:
volume of cubical box =l×b×h
=6×4×10
Ratio = 2:3 = 2/5
Distance between the x coordinates: 3
Distance between the y coordinates: 7
x: 3 * 2/5 = 1.2
y: 7 * 2/5 = 2.8
x coordinate of point: 6 - 1.2 = 4.8
y coordinate of point: 1 + 2.8 = 3.8
So the point that divides the segment AB in the ratio of 2:3 is (4.8 , 3.8) or (24/5 , 19/5)
Hope this helps :)
