Answer:
Step-by-step explanation:
The coefficients of the x terms are {1, 3, -3}, so the discriminant, b^2 - 4ac, is 3^2 - 4(1)(-3), or 9 + 12, or 21. The positive nature of the discriminant tells us that there are two real, unequal roots. Following the quadratic formula, we get:
-3 ± √21
x = -----------------
2
Answer:
Yes it is linear

Answer:
0.2
Step-by-step explanation:
θ =
arctan( ΔY ) + 180°
ΔX
= 168.69006752598°
ΔX = -2 – 3 = -5
ΔY = 6 – 5 = 1
Distance (d) = √ΔX2 + ΔY2 = √26 = 5.0990195135928
Equation of the line:
y = -0.2x + 5.6
or
y =
- 1 x
5
+ 28
5
When x=0, y = 5.6
When y=0, x = 28
Answer:
7.74596669241 (maybe)
Step-by-step explanation:
I havent really done this in a while but I started by making the line into a right triangle and counted how many boxes were inside(6 on the bottom 4 on the side). Then I used the Pythagorean theorem (which is the process of taking the sides and making them squares) < To simplify that explanation (I squared the sides(6 and 4).) so now we are left with 6² + 4² = x². next what you do is simplify your terms. (6² = 36, 4² = 24. 36 + 24 = 60) We have 60 = x² but we aren't don't yet, now we have to remove the square from x. and to do that we have to square root 60 and x² ( squared numbers being square rooted just leaves the regular number.) when square rooting 60 you are left with 7.8≈.
I hope this helps you, like i said its been a while since ive done this.
