X=8 because add 11 to both sides and it becomes 28=3.5x and divide both sides by 3.5 so x=8
Answer:
x=9 x=-1
Step-by-step explanation:
x²-8x-9=0 a=1 b=-8 c=-9
you have to use the quadratic formula to get the values.
First find the slope, take derivative of both sides with respect to x.
2y dy/dx=3x^2+6x
solve for dy/dx
dy/dx=[3x^2+6x]/2y
plug in given vales of (1,2(
dy/dx=9/4
now you have everything you need to plug into point slope form
y-2=(9/4)(x-1)
answer is y=(9/4)x+(1/4)
Answer:
792600
Step-by-step explanation:
For this question you can add four zeroes to the back of 792.6 andmove the decimal to get you the answer, hope this helps
It's also good to know that if the exponent was positive the answer would be 0.07926
