Answer:
4x² + 20x - 2
Step-by-step explanation:
To evaluate (c ○ d)(x), substitute x = d(x) into c(x)
c(x² + 5x)
= 4(x² + 5x) - 2
= 4x² + 20x - 2
Multiplying x^2 by 5 stretches the graph vertically by a factor of 5. Try graphing both x^2 and 5x^2 and see for yourself that this is correct.
25*8.14=?
Multiply the cost of the book per person ($8.14) by the number of people (25).
A mixed number is a whole number plus a fraction.
the smallest whole number is 1.
so no mixed number could be lees than 1.
mixed numbers that are 1/5 apart and are between 6 and 7
1-6/1 or 2-71
