C
5 is 1/3 of 15 and 1 is 1/3 of 3 so C would be correct
Answer:
8x² - 15y² + xy
Step-by-step explanation:
(4x + 5y) (2x - 3y) + 3xy
multiplying the terms in brackets
(4x) (2x - 3y) + (5y) (2x - 3y) + 3 xy
multiplying with each terms inside the bracket
(4x)(2x) - (4x) (3y) + (5y) (2x) - (5y) (3y) + 3xy
doing the product each of the pair of terms
8x² - 12xy + 10xy - 15y² + 3xy
taking the sum of terms with coefficient "xy"
8x² - 15y² -2xy + 3xy
8x² - 15y² + xy
The missing value for
is 
Explanation:
It is given that the equation for the table is 
The table has 2 column with 5 rows.
Thus, we have,
x y
-2 10
-1 ---
0 2
1 -2
2 -6
We need to determine the value of y when 
The value of y can be determined by substituting
in the equation 
Thus, we have,

Multiplying the term within the bracket, we have,

Adding the terms, we have,

Thus, the value of y when
is 6.
Hence, the missing value for
is 
What's up? this is C. the base fee, $15 does not change. so we can eliminate A and B. the rate, $8 per hour, will start rising when more hours are spent mowing. this is the same as saying "8h" so, it has to be C.
