Answer:
-1/2
Step-by-step explanation:
slope = rise/run = y1-y2/x1-x2 = -3-(-2)/-3-(-5) = -3+2/-3+5 = -1/2
Answer:
B, it's the only plausible one. A is wrong because the value would be above 180°
Answer:
X=1/2. X=4/3
Step-by-step explanation:
6x2+5X-4=0
6X2+8X-3X-4=0
2x(3x+4) - 1(3x+4)=0
2x-1) (3X-4)
X=1/2. X=4/3
Answer:
f(x) = -3(x - 5)^2 + 4
vertex (5,4)
Step-by-step explanation:
f(x) = -3x² +30x - 71
f(x) = -3(x² +-10x) - 71
f(x) = -3(x² +-10x+5^2-5^2) - 71
f(x) = -3(x² +-10x+5^2) -3(-5^2) - 71
f(x) = -3(x² +-10x+5^2) + 4
f(x) = -3(x - 5)^2 + 4
vertex (5,4)
Use the Pythagorean theorem:
