Point slope form: y1-y2=m(x1-x2)
Given the slope -4 and the set of coordinates (4,-9),
y+9=-4(x-4)
I plugged in the slope and coordinates. Since -9 came after a subtraction sign, I corrected the subtraction to addition, leaving the above point slope form equation.
I hope this helps :)
Answer:
Charles is incorrect
Step-by-step explanation:
Lupe bought 8 pounds of pretzels for $18, meaning that she bought them at a unit rate of $2.25 per pound. Charles bough 6 pounds of pretzels for $15, meaning he bought them at a unit rate of $2.50 per pound. Even though Charles paid less, he didn't get the better deal because he paid more per pound than Lupe did.
Answer:
relative minimum
Step-by-step explanation:
From f^''(x) = 12x we can take the integration to find out what f'(x) is:
Furthermore, we can substitute x = 1 for f''(x) to find out whether it's positive or negative
f''(1) = 12*1 = 12 > 0
So if x=1 is a critical point of f'(x) and f''(x=1) > 0 then that point is a relative minimum point
Answer:
It's a function not a linear function
Step-by-step explanation:
Step-by-step explanation:
The area <em>A</em> under the curve can be written as
To evaluate the integral, let
so the integral becomes
or
Putting in the limits of integration, our area becomes
