Answer:

She has 11 dimes and 17 nickels

Step-by-step explanation:

dimes --- d

nickels -- n

Equation with number of coins: $
n+d = 28
n = 28-d$

$10d + 5n = 195
$

Divide by 5

$2d + n = 39$

sub in the other equation:

$2d + 28-d = 39
d = 11
n = 28-11 = 17
$
She has 11 dimes and 17 nickels

check:

total = 11 + 17 = 28 , check!

value: 10(11) = 5(17) = 195 , check!

Answer:

Step-by-step explanation:

$y=-3(x^2+10x+25)-1\\ \\ y=-3x^2-30x-76\\ \\ dy=-6x-30\\ \\ d^2y=-6\\ \\ \text{Since the second derivative is always negative, when the first derivative is equal to zero the function will be at a global maximum.}\\ \\ dy=0=-6x-30\\ \\ x=-5\\ \\ f(-5)=-1\\ \\ \text{So the global maximum occurs at the point (-5,-1)$
