You're on the right track. After you get both equations you need to cancel one of the variables. In this situation, it doesn't matter which variable you cancel out.
Part (a)
Plug in y = 0 and solve for x. Use the zero product property
y = x(x+3)(x-2)
0 = x(x+3)(x-2)
x(x+3)(x-2) = 0
x = 0 or x+3 = 0 or x-2 = 0 .... zero product property
x = 0 or x = -3 or x = 2
The three roots or zeros are x = 0 or x = -3 or x = 2
================================================
Part (b)
The roots of the graph are: x = -2, x = 1, x = 3. Each root is where the graph crosses or touches the horizontal x axis.
Note how x = 0 is found in part (a), but not found here. This is one example where the graphs don't match. Another would be x = -3 is in part (a), but not here.
So that's why the graph does <u>not</u> match with the function in part (a)
Answer:
x-intercept is -1; y-intercept is 0.5.
Step-by-step explanation:
The x-intercept is relatively easy to read off. It's the x-value where the graph crosses the x-axis, and here is (-1,0).
The y-intercept is best estimated as (0,+0.5).
The correct answer is the 3rd one on the list.
Answer:
right prism
Step-by-step explanation:
If the faces are rectangles, then this prism is called a "right prism"
Answer:
216
Step-by-step explanation:
800 ÷ 100 = 8
8 = 1%
73 x 8 = 584
800 - 584 = $216
