Answer:

(-3,-6)

(0,-5)

(3,-4)

(5,-3)

Step-by-step explanation:

Step 1: Have 'x' values selected(make it multiples of 3 so 'y' is a whole number)

-3, 0, 3, 6

Step 2: Substitute the x to solve for y

$y=\frac{1}{3} (-3)-5\\y=-1-5\\y=-6$

$y=\frac{1}{3} (0)-5\\y=0-5\\y=-5$

$y=\frac{1}{3} (3)-5\\y=1-5\\y=-4$

$y=\frac{1}{3} (6)-5\\y=2-5\\y=-3$

Step 3: State your answers

Therefore the ordered pairs are:

(-3,-6)

(0,-5)

(3,-4)

(5,-3)

If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g – f)(3)?

Kryger [21]

For this case we have the following functions:

$f (x) = 4 - x ^ 2\\g (x) = 6x$

The first thing we must do for this case is to subtract both functions.

We have then:

$(g - f) (x) = g (x) - f (x)$

Substituting we have:

$(g - f) (x) = (6x) - (4 - x ^ 2)$

Rewriting we have:

$(g - f) (x) = x ^ 2 + 6x - 4$

Evaluating the obtained function for x = 3 we have:

$(g - f) (3) = (3) ^ 2 + 6 (3) - 4\\(g - f) (3) = 23$

Answer:

The value of the function evaluated at x = 3 is:

$(g - f) (3) = 23$

The cost of a plane ticket increases by 12%. After the increase, the ticket costs $616. What was the cost before the increase? E

Zina [86]

The cost before increase was $550.

Step-by-step explanation:

Given,

Increased price of plane ticket = $616

Increase percent = 12%

Let,

x be the original price of ticket.

Now,

The original price is 100% and 12% is increased, therefore;

New price = (100+12)% = 112%

Thus;

$616 is 112% of x.

112% of x = 616

$\frac{112}{100}x=616\\1.12x=616$

Dividing both sides by 1.12

$\frac{1.12x}{1.12}=\frac{616}{1.12}\\x=550$

The cost before increase was $550.
