Isolate for y.
x - 2y =8
x-8 = 2y
(x-8)/(2) = y
(x/2) - (8/2) = y
y = (1x/2) - (4)
f(x) = (1/2)x - 4
The answer is D.
There isn’t one unless I’m blind
Answer:
There would be 104 rooms on 4 floors in total.
Step-by-step explanation:
If there were 26 rooms on 2 floors, then you multiply 26 x 4, the result would be 104 rooms on 4 floors in total.
ANSWER

EXPLANATION
We want to simplify the expression,

Let us expand the bracket to obtain,

We now group the complex number parts and real number parts.

We simplify further to obtain,

This is in the form,

where

and
c = cost of food/med for cats
d = cost of food/med for dog
y = total cost/spent
What you know:
y = 6c + d [has 6 cats and 1 dog]
c = 2/3d - 5 [cost for cat is 5 less than 2/3 cost for dog]
y = $195
y = 6c + d
Substitute/plug in what you know, plug in (2/3d - 5) for c and 195 for y
195 = 6(2/3d - 5) + d Distribute/multiply 6 into (2/3d - 5)
195 = 4d - 30 + d Combine like terms
195 = 5d - 30 Add 30 on both sides of the equation
225 = 5d Divide 5 on both sides
$45 = d
