Answer:

f(-3)

f(a) = -2a² - 5a + 4

Substitute a with its value, -3

f(-3) = -2(-3²) - 5(-3) + 4

f(-3) = -2(9) + 15 + 4

f(-3) = -18 + 19

f(-3) = 1

the value of f(-3) is 1.

1) You are attending the first Lil Baby concert after quarantine. There are two levels, one level
Ksenya-84 [330]

Answer:

Total number of people in the concert

= 186

Step-by-step explanation:

There are 80 people in level 2

Then in level one

The dimensions of the room are 62 feet by 31 feet.

15 people fit in a 3 feet by 6 feet space.

Area of the room= 62*31= 1922 feet²

area of 15 people space= 3*6= 18 feet²

To know how many 15 people we get in the 2nd level

=Area of room/area of 15 people space

= 1922/18

= 106.77

= 106 (we round down because this is human being.)

Total number of people in the concert

= 106+80

= 186

Kevin bought a membership to a golf club. He pays $250 per month and $18 every time he plays a round of golf. Write an equation
Arturiano [62]
Hi there!

Let's solve this problem step by step!

The cost of 1 round of golf is $18
and therefore the total cost for all of the tickets is $18 × 
the amount of golf plays, mathematically $18 × g, hence 18g

The membership cost of 1 month is $250
and therefore the total cost for all of the tickets is $250 × 
the amount of months, mathematically $250 × m, hence 250m.

Now we can set up the equation. The only thing we need to do is adding up the individual functions.

Answer:
C = 250m + 18g
