Heyyy ummm... help??

The statements true for the given function are:

$f(0) = \frac{3}{2}$
$f(4) = \frac{7}{2}$

I tried them all and these two were correct, their solutions are as follows:

= f(x) = 1/2x + 3/2

= f(0) = 1/2 × 0 + 3/2

= f(0) = 0 + 3/2

= f(0) = 3/2

= f(x) = 1/2x + 3/2

= f(4) = 1/2 × 4 + 3/2

= f(4) = 2 + 3/2

= f(4) = 4+3/2

= f(4) = 7/2

So, that's how these two are correct.

A local charity sponsors a 5K race to raise money. It receives $25 per race entry and $5,000 in donations, but it must spend $5

kenny6666 [7]

they receive 25 per entry but 5 goes towards the cost of the race

so 25-5 = 20 per entry is for the charity

so 20x + 5000 = 25000

subtract 5000 from each side

20x= 20000

divide both sides by 20

x = 20000/ 20

x = 1000

they need at least 1000 entries to make 25000

so to make more than 25000, they need 1001 entries
