Answer:
Step-by-step explanation:
y = -5x - 17
in y = mx + b form, the y int is in the m position
y = mx + b
y = -5x - 17......so the y int (b) = -17 or (0,-17) <=== y intercept
u can also find the y intercept by subbing in 0 for x and solving for y
u can find the x intercept by subbing in 0 for y and solving for x
y = -5x - 17
0 = -5x - 17
5x = -17
x = -17/5......so the x intercept is -17/5 or (0,-17/5) <==== x intercept
X intercept is where x=0
y intercept is where y=0
16 n^2 -10n + 129 = 8n^2 -8
We collect the terms:
8n^2 -10n + 137 = 0
The steps for completing the square:
1) Move the "non X" (or "non N") term to the right:
8n^2 -10n = -137
<span>2)<span> Divide the equation by the coefficient of N² which in this case is 8
n^2 -1.2n = </span></span><span><span>-17.125
</span>
3) Take the coefficient of "N"; divide it by 2; square it; add it to both sides of the equation.
-1.2 / 2 = -.6
-.6^2 = .36

n^2 -1.2n +.36 = <span>-17.125
+.36
Take the square root of both sides:</span>
(n-.6)*(n-.6) = sq root(

That's about as far as I can go.
