<em>If f(1) = 1 that means c is -2 because when you substitute x = 1 and when c = -2, you'll get f(1) = -2(1)+3 = -2+3 = 1</em>
<em>So the constant c is -2 and that means the value of f(-4) is</em>
<em>f(-4)=-2(-4)+3=8+3=11</em>
<em />
<em>Thus, the value of f(-4) is 11.</em>
<em />
<em>About why does "c" have to be -2, here's the proof.</em>
<em>Given y = f(x), therefore.</em>
<em>y=cx+3</em>
<em>Since when x = 1 and y = 1, then Substitute x = 1 and y = 1, thus 1 = c+3</em>
<em>1 - 3 = c and therefore, -2 = c #</em>
<em>So this is the proof that c = -2</em>
$24 per hour * 263 hours = $6,312
It is a rate per hour times hours worked.
Answer: 182 gallons
find 30% of 260 by multiplying 260 by 30%
260 x .3 = 78
30% of 260 = 78
Subtract 78 from 260 to get original amount
260 - 78 = 182
Original is 182 gallons
ps. this is an actual impossible question because you need to know the original amount to find what 30% of it is. What i found was a 30% decrease of 260 not a 30% increase of the original. With that being said I think this is what you want?
The "unit rate" appears to be $20 per ticket.
No clue what the answer is I am not that good I am blonde
now goodbye
