Answer: 24

Step-by-step explanation: if x=6 then f(x)=4x turns into f(6)=4(6). 4 x 6=24

So when you have one of these, it’s just asking you so solve it as if x were 6 (as you see where the x in f(x) is replaced with a 6.

so you’d sub x for 6

giving you:

4 x (6)

which = 24

hope that makes sense :)

Eva is picking fruit at a farm. The fees are $5 for entry to the farm, $2.50 per pound of blueberries, and $2 per pound of apple

olasank [31]

Answer:

The required expression is: $y = 5 + 2.50b + 2a$

Step-by-step explanation:

Given

$Entry = \$5$

$Blueberry = \$2.50$

$Apple = \$2$

Required

Write an expression for this scenario

If 1 pound of blueberry cost $2.50

then b pounds = 2.50 * b

If 1 pound of apple cost $2

then a pounds = 2 * a

The required expression (y) is then calculated as

$y = Entry\ Fee + Blueberry = Apple$

$y = 5 + 2.50 * b + 2 * a$

$y = 5 + 2.50b + 2a$

Hence, the required expression is: $y = 5 + 2.50b + 2a$
