Let’s start with -4(-3x + 11) so, -4•-3x is 12x,because multiplying 2 negatives creates a positive. As for -4•11, it is -44. So, it should be 12x + -44. I hope this helps!
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
Cheers.
Answer:
3x^2 - 8x + 4.
Step-by-step explanation:
36x^3 - 96x^2 + 48x
Dividing by 12 term by term:
= 3x^2 - 8x + 4.
Answer:
Step-by-step explanation:
plug all in
1) 0 when x=0
2) 1*6-1²=6-1=5
3) 6*2-2²=12-4=8
4)6*3-3²=18-9=9
5) 6*4-4²=24-16=8
6)6*5-5²=30-25=5
7) 6*6-6²=36-36=0
Solve the equation by substitution method.
To get b-2-3b=4. Then you substitute b into simplest to get, b=-3. Repeat the same process with a to get, a=-5. So your answer would be (-5, -3)
