Answer: see below
<u>Step-by-step explanation:</u>
f(x) = x(19 - x)
= 19x - x²
A) f(x+h) = (x + h)[19 - (x + h)]
= (x + h)(19 - x - h)
= 19x - x² - 2xh + 19h - h²
B) f(x+h) - f(x) = (19x - x² - 2xh + 19h - h²) - (19x - x²)
= - 2xh + 19h - h²
= h(-2x + 19 - h)
C) [f(x+h) - f(x)]/h = [h(-2x + 19 - h)]/h
= -2x + 19 - h
As h → 0: = -2x + 19
There's no solution, as the shaded areas don't overlap
Answer:
h*h=10*10+3*3
h*h=100+9
h*h=109
square root of h=square root of 109
h=10.44
Answer:
58 degrees.
Step-by-step explanation:
m<3=180-119=61
Write the equation :
61+(10x-22)+(9x-11)=180
x=8
m<1= 58 degrees
Answer:
m = 299
Step-by-step explanation:
When isolating variables, you must do the same thing to both sides of the equation. To isolate "m", you must add 77 to both sides.
m - 77 = 222 <----- Original equation
+77 +77 <----- Add 77 to both sides
m + 0 = 299 <----- Resulting equation
m = 299 <----- Rewrite
