Answer:
.5 or 1
Step-by-step explanation:
Subtract 3 on both sides.
4 = 9
and now you will divide by 4
4/4. 9/9 = 0.444444.......
and it will equal to .5 or 1
In order to find any of the info we need we have to find the first derivative of the equation. If

, then

. We are told to find the slope at point (1, 7). Using that x value in our derivative will give us the slope of the line at that point. y' = -(1)^2+8. So y' = 7. That's the slope of the line. Now we will use that slope along with the x and y coordinate in the slope-intercept form of a line to solve for b. 7 = 7(1) + b so b = 0. Our equation then is y = 7x. If you graph these in the same window on your calculator, you can see how perfectly that align at the given point. It's really quite perfect.
Answer:
Well if you have -4 and want to get to -1 you can add +3 to -4 to get -1
Step-by-step explanation:
Answer: The answer is 1,037. You did good with the first three steps but you need to do the same for the last step, because you have 21 you have to find how many times 3 goes into it, which would be 7, and that gives you your full answer of 1,037.
