Answer:
Step-by-step explanation:
The definition of derivative states that:
Then:
A constant function is a zero-order polynomial. The domain of any real polynomial is . Then, the domain of the function is:
Total muffins and doughnuts = 18
Assumed all doughnuts = 18 x $0.4 = $7.20
But she paid $9.15.
$9.15 - $7.20 = $1.95
$1.95 must have been used to pay for the muffin.
Difference in price between muffin and doughnuts:
$0.55 - $0.40 = $0.15
Number of muffins bought = $1.95 ÷ 0.15 = 13
She bough 13 muffins.
Number of doughnut bought = 18 - 13 = 5
She bought 5 doughnuts
Answer: She bought 5 doughnuts and 13 muffins.
Answer:
a (9 - 8 a x)
Step-by-step explanation:
Simplify the following:
3 a - 2 a x×4 a + 6 a
-2 a x×4 a = -2 a^2 x×4:
3 a + -2 a^2 x×4 + 6 a
-2×4 = -8:
3 a + -8 a^2 x + 6 a
Grouping like terms, 3 a - 8 a^2 x + 6 a = -8 a^2 x + (3 a + 6 a):
-8 a^2 x + (3 a + 6 a)
3 a + 6 a = 9 a:
-8 a^2 x + 9 a
Factor a out of -8 a^2 x + 9 a:
Answer: a (9 - 8 a x)
Answer:
I think -6
Step-by-step explanation:
-12 +6 is -6 so -6 + -6 =-12
Answer:
7x - 6y = 16
y = (-5)
using substitution method
7x - 6(-5) = 16
7x +30 = 16
7x = 16 - 30
7x = 14
x = 14/7
x= 2
