Answer:
B) y=-3/2x-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-6-3)/(2-(-4))
m=-9/(2+4)
m=-9/6
simplify
m=-3/2
y-y1=m(x-x1)
y-3=-3/2(x-(-4))
y-3=-3/2(x+4)
y=-3/2x-12/2+3
y=-3/2x-6+3
y=-3/2x-3
Hello
All square numbers ends with 0,1,4,5,6 or 9 at units place.
Answer:
The answer in each numeral is:
- <u>f(4) = 28</u>
- <u>f(10) = -19</u>
- <u>f(-5) = -33</u>
- <u>f(9) = -9</u>
Step-by-step explanation:
To obtain the result in each case, you must replace the variable (n) by the value that appears in the second case, I'll explain it with the first exercise:
- 1. f(n) = 5n + 8
- f(4) = ?
As you can see, in the second doesn't appear f(n), but f(4), that means you must replace the "n" in the equation by 4, if we do this, we obtain:
- 1. f(4) = 5*(4) + 8
- f(4) = 20 + 8
- <u>f(4) = 28</u>
The first answer is 28, now we'll continue with the next exercises:
- 2. f(n) = -2n + 1
- f(10) = -2*(10) + 1
- f(10) = -20 + 1
- <u>f(10) = -19</u>
- 3. f(n) = 6n - 3
- f(-5) = 6*(-5) - 3
- f(-5) = -30 - 3
- <u>f(-5) = -33</u>
- 4. f(n) = -n
- <u>f(9) = -9</u>
In this form, <u><em>you can prove the answers are: 28, -19, -33, and -9 respectively</em></u>.
Not completely sure but i think y is 3
