Answer:
G) y=3x+1
Step-by-step explanation:
1 would equal b = y-intercept
-3 is the slope = m
y-intercept form is y=mx+b
plug it in
y=-3x+1
When you draw a horizontal line through the given solution point, you find it intersects the unit circle at 150°. Thus the appropriate choice for the remaining solutions will be
... 30° + n•360°, 150° + n•360°
Answer:
Step-by-step explanation:
Step 1: Subtract -2x from both sides.
x2+x−7−−2x=−2x−−2x
x2+3x−7=0
For this equation: a=1, b=3, c=-7
1x2+3x+−7=0
Step 2: Use quadratic formula with a=1, b=3, c=-7.
x= −b±√b2−4ac / 2a
x= −(3)±√(3)2−4(1)(−7) / 2(1)
x= −3±√37 / 2
x= −3/2 + 1/2 √37 or x= −3/2 + −1/2 √37
Answer:
x= −3/2 + 1/2 √37 or x= −3/2 + −1/2 √37
