x =(-2-√-12)/8=(-1-i√ 3 )/4= -0.2500-0.4330i
x =(-2+√-12)/8=(-1+i√ 3 )/4= -0.2500+0.4330i
x = 1/2 = 0.500
Answer:
The equation has one solution.
Step-by-step explanation:
6x + 35 = -6x - 35
subtract 6x from both sides of the equation
35 = -35 - 12x
add 35 to both sides of the equation
70 = -12x
divide -12x on both sides of the equation
x = 5.833333333
Answer:
At (-2,0) gradient is -4 ; At (2,0) gradient is 4
Step-by-step explanation:
For this problem, we simply need to take the derivative of the function and evaluate when y = 0 (when crossing the x-axis).
y = x^2 - 4
y' = 2x
The function y = x^2 - 4 cross the x-axis when:
y = x^2 - 4
0 = x^2 - 4
4 = x^2
2 +/- = x
Hence, this curve crosses the x-axis twice, once at (-2,0) and again at (2,0).
The gradient at these points are as follows:
y' = 2(-2) = -4
y' = 2(2) = 4
