Ill give 99 points! given the function f(x) = −5x2 + 2x + 9, find f(1) and f(2). choose the statement that is true concerning these two values. the value of f(1) cannot be compared to the value of f(2). the value of f(2) is larger than the value of f(1). the value of f(2) is smaller than the value of f(1). the value of f(1) is the same as the value of f(2).

The value of f(2) is smaller than the value of f(1).

Step-by-step explanation:

First you plug in the numbers for x.-->f(1)=-5(1)2+2(1)+9

Then you solve this equation.-->f(1)=-5(2)+2+9 =-10+11 =1

Then you repeat both steps for f(2).-->f(2)=-5(2)2+2(2)+9 =-20+4+9 = -7

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

hi how are you doing today? if you ever need just tell me
