Answer:
D.
Step-by-step explanation:
All other equations have x or y to the power of one so they are linear. D. has x or y to the power of two, so it's not linear. Quadratics and any variable to the power of 2 and above is not linear (numbers on their own are also always linear, so ignore any powers on them)
It's going to be 35 present
Answer:
C. 32%
Step-by-step explanation:
First, you have to determine the amount they spent on entertainment and food:
Salary $2,700
Taxes: 10%: $270
Fixed expenses: $1,161
Savings: $405
$2,700-$270-$1,161-$405= $864
Alycia spent $864 on entertainment and food. Now, you have to find the percent of her income that this amount represents:
($864/$2,700)*100= 32%
According to this, the answer is that the percent of her income that was spent on entertainment and food is 32%.
Answer:
C = 
Step-by-step explanation:
given A varies directly as B and inversely as C then the equation relating them is
A =
← k is the constant of variation
to find k use the condition A = 6 , B = 10 , C = 15 , then
6 =
( multiply both sides by 15 )
90 = 10k ( divide both sides by 10 )
9 = k
A =
← equation of variation
when A = 92 and B = 107 , then
92 =
( multiply both sides by C )
92C = 963 ( divide both sides by 92 )
C =
