The answer is 20 because since Serena is 10 and her mother is 3 times her age. So 10x3= 30 and 0.5 or 1/2 of her moms age is 20 so when her mom is 40 serna will be 20 and her mom had her at 20

Find the slope of the function f ( x ) = 3 - 2 x , by the definition of limit.
musickatia [10]

Answer:

the slope is -2\lim_{n \to \0}( f(x+h)-F(x)) /h \\\\ \lim_{n \to \0} (3-2(x+h)-(3-2x))/h\\ f(x+h)= 3-2(x+h) \\f(x)=3-2x\\ \\\lim_{n \to \0}  (3-2x-2h-3+2x)/h\\\\ \lim_{n \to \0} -2h/h\\  \\ \lim_{n \to \0} -2\\=-2\\\\In all limits, you have to put n goes to 0 (zero)

-3(k+7)-5k+4=23 what is the value of K?
skad [1K]
-3(k+7)-5k+4=23
-3k-21-5k+4=23
Get rid of the numbers that aren't being multiplied by k:
-3k-5k=23+21-4
Add like things:
-8k=40
Divide by -8 on both sides to get k by itself and to make the equation even:
k=-5
