Answer:
Option D In step 4 Keith should have subtracted 5 from each side
Step-by-step explanation:
step 1
we have
f(x)=7x+5 -----> given
step 1 is correct
step 2
Change f(x) to y
y=7x+5
so
step 2 is correct
step 3
Exchange x for y and y for x
x=7y+5
so
step 3 is correct
step 4
Subtract 5 each side
x-5=7y+5-5
x-5=7y
<u><em>step 4 is not correct</em></u>
step 5
Divide by 7 each side
(x-5)/7=y
step 6
Change y to g(x)
(x-5)/7=g(x)
step 7
switch sides of the equation
g(x)=(x-5)/7
therefore
In step 4 Keith should have subtracted 5 from each side

Those two numbers can't be directly added as long as they're in
radical form. The only way to add them is to find both square roots,
and then add those.
Another twist is the fact that every number has two square roots ...
one positive and the other negative. So there are four possible sums
of (√3 + √4) .
√3 = + or - 1.732051 (rounded)
√4 = + or - 2 (exactly)
The four sums are:
(+1.73205) + (+2) = <em>3.732 </em>(rounded)
(+1.73205) + (-2) = <em>-0.268</em> (rounded)
(-1.73205) + (+2) = <em>+0.268</em> (rounded)
(-1.73205) + (-2) = <em>-3.732</em> (rounded)
25. You need to divide 3240 by 6, and 1100 by 2. Are those equal? That's what it's asking. It would not be equal, because 3,240 miles would be 540 miles per hour and 1100 would be 550 per hour. Very close, however.
26. If 15 scoops makes 5 gallons, then divide 15/5. That's 3 scoops per gallon. It's asking how many gallons can be made with 6 scoops. That would be 2 gallons.
27. All it's asking is 38 times 5, which would be 190.
28. Since 5 gallons goes into 15 gallons three times, you would divide $22.20 by 3. That would be $7.40 each 5 gallons.
