In a table it's EXAMPLE: Cars/Drivers the cars is x and the drivers is y(y-intercept). In an equation, EXAMPLE using y=mx+b the b is the y-int., and in a graph it is (x,y) the y being the y-int.

Answer:

Table: The y coordinate value corresponding to x = 0

Equation: c is the y-intercept.

Graph: curve passes the y- axis

Step-by-step explanation:

We have to find how does the y-intercept appear in these three representations: table,equation,and graph.

Y-intercept:

The y-intercept of this line is the value of y at the point where the line crosses the y axis.
Thus, y-intercept is the value of y when x is 0.

In table:

The table shows the x coordinate and the corresponding y coordinates. The y coordinate value corresponding to x = 0 in the table is the y intercept.

In equation:

The slope intercept form of straight line is given by:

$y = mx + c$

where m is the slope of the line and c is the y-intercept.

In graph:

The point on the graph where the curve passes the y- axis that is the x value is zero.

Answer:

the equation is y= 3x - 1

Step-by-step explanation:

to find the intersection with x just substitute 0 to Y.

0=3x-1

3x=1

x=1/3

Answer:

the answer is 10 percent off because that is 13 dollars

Step-by-step explanation:

if you do 130 times 10 it is 1300, then divide by 100 it equals 13 dollars off. if you did the other coupon it would only be 10 dollars off

Factor f(x) = 15x^3 - 15x^2 - 90x completely and determine the exact value(s) of the zero(s) and enter them as a comma separated

Illusion [34]

Answer:

$x=-2,0,3$

Step-by-step explanation:

We have been given a function $f(x)=15x^3-15x^2-90x$ . We are asked to find the zeros of our given function.

To find the zeros of our given function, we will equate our given function by 0 as shown below:

$15x^3-15x^2-90x=0$

Now, we will factor our equation. We can see that all terms of our equation a common factor that is $15x$ .

Upon factoring out $15x$ , we will get:

$15x(x^2-x-6)=0$

Now, we will split the middle term of our equation into parts, whose sum is $-1$ and whose product is $-6$ . We know such two numbers are $-3\text{ and }2$ .
