Answer:
xy*(2x^2 + 7x^2 - y^2)
Step-by-step explanation:
You can get xy out of the expression since all have xy
The sides of the rectangle are aligned with the coordinate axes, so the dimensions of the rectangle are easily determined to be 4 -(-7) = 11 units by 1 -(-1) = 2 units. As with any rectangle, the area is the product of length and width.
The area is 11*2 = 22 square units.
Answer:
35 x 2.51 = 87.85
36 x 2.51 = 90.36
If he cannot spend more than 90 than the maximum amount he can afford is 35.
Step-by-step explanation:
It would actually be -14 because 5+4-2=7 and if you multiply 7 by -2 you get -14
A ) The data in this table represents a function.
This function is : f ( x ) = 1/2 x
B ) f 1( 8 ) = 1/2 * 8 = 4 (also from the data in the table)
f 2( 8 ) = 3 * 8 - 10 = 24 - 10 = 14.
Second relation has a greater value when x = 8
C ) f ( x ) = 80
3 x - 10 = 80
3 x = 90
x = 90 : 3
x = 30
