2. Evaluate f(x) = 3x+5/x-1<br> at x = 3

pashok25 [27]

Answer

Let f(x) = ax + b

Then

f(x + 1) = a(x + 1) + b

= ax + a + b

Hence, a = 3, and a + b = 5, b = 2

f(-2) = 3(-2) + 2

= -6 + 2

= - 4

f(2x) = 3(2x ) + 2

= 6x + 2

Camacho is buying a monster truck. The price of the truck is xxx dollars, and he also has to pay a 13\%13%13, percent monster tr

alexandr402 [8]

Although the information has been presented in a baffling way in this question, but I think I understood the expressions.

We have been given that price of monster truck is x dollars and there is an 13% monster truck tax.

We can express the monster truck tax amount as $\frac{13}{100}\times x = 0.13x$ .

Therefore, the total amount including tax will be $x+0.13x = 1.13x$ .

We can now match each statement with its equivalent expression as shown below

The price of Camacho’s new truck before tax = x

The amount of tax Camacho pays = 0.13x

Camacho’s total bill for the monster truck = 1.13x

None of these = 0.87x

Dave has 10 poker chips, 6 of which are red and the other 4 of which are white. Dave likes to stack his chips and flip them over

Marina86 [1]

The number of 10 chips stacks that Dave can make if two stacks are not considered distinct is 110.

The solution

To get the symmetric stacks, one has to subtract the symmetric stacks to know the ones that are asymmetric.

The symmetric are flipped. Given that they are double counted what we have to do is to divide through by 2.

6/2 = 3

10/2 = 5

4/2 = 2

1/2(10C6) - (5C3) + (5C3)

0.5(210-10+10)

= 110
