If f(-3) = -8, then f(x)= 3x +
Nataly_w [17]

Answer:

f(x)= 3x + 1

Step-by-step explanation:

Let's set the unknown variable as b, since it's a linear equation.

Using the point given (-3, -8), we can find b by plugging in the known numbers and solving.

-8 = -3 (3) + b

-8 = -9 + b

b = 1

If you want, you can check it by forming the complete equation and plugging in -3.

f(x)= 3x + 1

f(-3) = -9 + 1

f(-3) = -8 = -8

I hope this helped!

Katie buys a large pizza for $14.99 and bottles of soda for $1.50 each. If the total cost was $23.99, how many bottles of soda (
Nady [450]

The number of soda bottles Katie bought is 6

The given parameters are:

  • Large Pizza = $14.99
  • Soda = $1.50 per bottle
  • Total cost = $23.99

Assume the number of soda bottle is x.

So, we have:

Total = Pizza + Soda \times x

This gives

23.99 = 14.99 + 1.50\times x

Subtract 14.99 from both sides of the equations

9 = 1.50\times x

Divide both sides of the equations by 1.5

6=x

Rewrite the equation as

x = 6

Hence, the number of bottles is 6
