Answer:

f(3) + f(-3) = 10

Step-by-step explanation:

f(3) = 5 - 2(3)

f(-3) = 5 - 2(-3)

f(3) + f(-3) = 5 - 2(3) + 5 - 2(-3)

f(3) + f(-3) = 5 - 6 + 5 +6

f(3) + f(-3) = -1 + 11

f(3) + f(-3) = 10

In the diagram below, RSTU is a rectangle, and the two shaded regions are squares.

sdas [7]

Answer:

length PQ = 8.9 m

Step-by-step explanation:

The picture below completes the question you asked. From the picture above RSTU is a rectangle . The two shaded square has a length of sides 8 m and 4 m respectively. The legs of the triangle is the sides of the 2 squares. Therefore, the triangle is a right angle triangle. The adjacent side is 4 m while the opposite side is 8 m.

Using Pythagoras theorem the hypotenuse of the triangle can be calculated below.

Pythagoras theorem

c² = a² + b² Therefore,

c² = 4² + 8²

c² = 16 + 64

c² = 80

square root both sides

c = √80

c = 8.94427191

c ≈ 8.9 m

length PQ = 8.9 m

Answer:

$5.50p+45\leq 80\\\\p\leq 6.36\\\\\Rightarrow p\leq 6$

Step-by-step explanation:

$Ben\ invited\ p\ peoples\\\\$

Charges of birthday party:

$Flat\ fees=\$ 45\\\\Per\ person\ charges=\$ 5.50\\\\Charges\ for\ p\ people=p\times per\ person\ charges\\\\Charges\ for\ p\ people=p\times 5.50\\\\Charges\ for\ p\ people=5.50p\\\\Total\ charges\ for\ party=flat\ fee+charges\ for\ p\ person\\\\Total\ charges\ for\ party=45+5.50p$

$Ben\ has\ money=\$ 80\\\\Ben\ can\ not\ spend\ more\ than\ that.\\\\\Rightarrow Party\ charges\ for\ p\ peoples\leq 80\\\\5.50p+45\leq 80\\\\5.50p+45-45\leq 80-45\ \ \ \ \ \ \ \ \ subtract\ 45\ from\ both\ sides\\\\5.50p\leq 35\\\\p\leq \frac{35}{5.5}\\\\p\leq 6.36\approx 6\\\\p\leq 6$
