I got 1808 is your multiple choice wrong?
Answer (-3,6)
#
f(x)=x ² +6x+15
=(x ² +6x+9)+6
=(x+3) ²+6
the vertex:(-3,6)
Answer: Yes
Step-by-step explanation: If V=12
Then we plug in for the inequality and get 12>7
Let x be the number of pennies which is also equal to the number of dimes. By this representation, the number of quarters is equal 46 - 2x. The total amount is $4.87 or 487 cents. The equation that best represent the given is,
x + 10x + 25(46 - 2x) = 487
The value of x from the equation is 17. Therefore, there are 17 of both pennies and dimes and 12 quarters.
