Answer:
<h3>#1</h3>
- x² - 9 = 0
- x² = 9
- x = ± √9
- x = ± 3
Yes, -3 and 3 are zeroes of this polynomial
<h3>#2</h3>
<em>See attached graphs</em>
Zero's of a polynomial are the intersection of the graph with the x-axis.
They include coordinates as (x, 0), so the x-coordinates are zero's.
The attached shows the zero's.
<h3>#3</h3>
<em>See attached graphs</em>
Zero's of each polynomial are reflected in the graphs.
- () y = x² - x - 6 has zeros x = -2 and x = 3
- (ii) y = 6 - x - x² has zero's x = -3, x = 2
Answer:
10(32 - n)
Step-by-step explanation:
This is a beginning algebra question. It is trying to find out if you know what a difference is.
A difference always means subtract in math. Always. There are no exceptions.
So the difference between 32 and n is 32 - n
This difference is multiplied by 10
10(32 - n)
Usually the number mentioned first is the number put to the left of the subtract sign.
If you tell me the answer is 10(n - 32) then you should say that it is the difference between n and 32.
Answer:
Step 2 has the error
1. The whole number (20) was left out
2. Adding different signs, we subtract and retain the sign from the larger number
Correction:
Step 2: 20 - 17x = 34x + 60
Step 3: -17x -34x = 60 - 20
Step 4: -51x = 40
Step 5: x = 40/-51
Their slopes would be the same but their positions or points ( if the lines were on a graph) would be different.
