Step-by-step explanation:
2nd qestions explanation
put value of x=2 in equation as x-2=0 from equation
(2)^3-6(2)^2+a2+10=2
8-24+a2+10=0
2a=-18+24
2a=6
a=3
Sin125, on the unit circle, should be positive(not negative), since it should be in quadrant two if the angle 125 degrees is in standard position.
It results in -2x because 1+1=2 and its the same with negative numbers
Answer:
Equation C
Step-by-step explanation:
Notice that the y-intercept is (0, 1). Only Equations 2 and 3 have that feature. Arbitrarily choosing x = 2 and looking up the value of y, we get y = -3.
Does this point (2, -3) satisfy Equation B? Is -3 = -(2) + 1 true? NO, so we eliminate Equation B and focus on Equation C:
Does the point (2, -3) satisfy Equation C?
Is -3 = -2(2) + 1 true? Is -3 = -4 + 1 true? YES. So Equation C is the correct choice here.
