Answer:
f(x) = 20-2x
Step-by-step explanation:
f(x) = 20-2x
f(6)=20-2*6=20-12=8
She can get a $5 lunch and still play 6 games, since after 6 games she still has $8.
We have that
x------------------> <span>represent the number of hours Steven babysits
y----------------- > </span><span>represent the amount he charges
for x=6 hours
y=</span><span>$37.50 ----------------> y/x=37.5/6=6.25
</span>for x=8 hours
y=$50---------------------> y/x=50/8=6.25
therefore
y=6.25x
the answer is
y=6.25x
It is already given in the question that that freezing temperature of water is 0 degree Celsius. The freezing temperature of water in degree Fahrenheit is required to be found.
We know the relation between degree centigrade and degree Fahrenheit is"
Degree Fahrenheit = C(9/5) + 32
Here in the above equation "C" represents degree centigrade.
From the question we already know the freezing temperature of water as 0 degree Centigrade. Now we have to replace the value of Centigrade in the equation
Degree Fahrenheit = C(9/5) + 32
= 0(9/5) + 32
= 0 + 32
= 32 degrees
So water freezes at 32 degrees Fahrenheit.

1) For a quadratic equation, we'll have two answers typically. We're looking for two numbers that when multiplied give -64, and when added give -12. This is a bit of trial and error, but you go about it by systematically factoring -64 in all possible combinations: 64=-2*32=2*-32=-4*16=4*-16=-8*8. Of these, I can 'see' that I can make -12 with 4 and -16. So the factorization of the equation becomes:
(x-16)(x+4)=0, so x=16 or x=-4.
Answers B and D are correct.
For (2), same trick applies. Rewrite as x²-8x-48=0. Factor as (x+4)(x-12)=0 because 4*-12=-48 and 4-12=-8. The other solution is x=12.
