JulsSmile [24]

Answer: 3/32

Step-by-step explanation:

Here's the complete question:

Helen used 1/4 of her savings for her first year of college. 3/8 of that money was spent on her housing and meals. Which equation shows the fraction of her total savings that was spent on her housing and meals?

Since we are told that Helen used 1/4 of her savings for her first year of college and that 3/8 of that money was spent on her housing and meals.

To calculate the fraction of her total savings that was spent on her housing and meals, we would multiply 1/4 by 3/8. This will be:

= 1/4 × 3/8

= 3/32

F(x + h) – f(x)
olga nikolaevna [1]

9514 1404 393

Answer:

  -6x² -6xh -2h²

Step-by-step explanation:

Apparently, you want ...

  (f(x+h) -f(x))/h

for f(x) = 14 -2x³

That difference quotient is ...

  \dfrac{f(x+h)-f(x)}{h}=\dfrac{(14 -2(x+h)^3)-(14-2x^3)}{h}\\\\ =\dfrac{14-2(x^2 +3x^2h+3xh^2+h^3)-14+2x^3}{h}=\dfrac{-6x^2h-6xh^2-2h^3}{h}\\\\ =\boxed{-6x^2 -6xh-2h^2}

Valentin [98]

Answer :A)-2

Step-by-step explanation: If you multiply B; x + 9y =10 by -2 you will      have -2 x+ -18y= -20. Then when you add B with a 2x + 8y = 5

                                                                                      -2x +-18y=-20

                                                                                      =0 +-10y=-15
