Answer:
it is not a direct variation
Step-by-step explanation:
To have a direct variation
y/x = k for all values of x and y
y/x = 11/7
y/x = 13/8
y/x = 15/9 = 5/3
y/x = 17/10
11/7 does not equal 13/8 so it is not a direct variation
Answer:
$17.12
Step-by-step explanation:
First let's find the normal cost with tax
7/100*19=133/100=$1.33
$19+$1.33=$20.33
Now we find the cost with tax for the Valentine's Day price
7/100*35=$2.45
$35+$2.45=$37.45
Now we subtract the normal cost from the Valentine's Day price
$37.45-$20.33=$17.12
Answer:
No because if you cross multiply 50x3= 150 while 27x6 is like 162 so no
Step-by-step explanation:
1-

calculate the powers behind the brackets from left to right
2-

Calculate the powers (a power squared means the number times itself so 2 squared equals 4)
3-

Calculate the sum ( minus minus equals plus so for example 4- -5= 4+5=9)
4- 49+5+2= 56
