Add the like terms.
The like terms in this case are:
-4x^2 and -2x^2
This makes -6x^2
-3y and 5y
This makes 2y
-8 and 1
This makes -7
Your answer is (-6x^2+2y-7)
Answer:
She can buy no more than 22 decorations
Step-by-step explanation:
The costs for the party are food and decorations
Cost = food + decorations * costs per decoration
We can spend no more than 300
Food is 75
Decorations are 10 each
Let d= the number of decorations
300 >= 75 + 10 * d
Subtract 75 from each side
300-75 >= 75-75 + 10 * d
225 >= 10d
Divide each side by 10
225/10 >=10d/10
22.5 >=d
She can buy no more than 22 decorations
Its 300cm from the square root
(x,y)
sub those for x and y and see if you get a true statement
(2,-8)
6(2)+-8=-4
12-8=-4
4=-4
fasle
(2,8)
6(2)+8=4
12+8=4
20=4
false
(1,2)
6(1)+2=4
4+2=4
6=4
false
(1,-10)
6(1)+-10=4
6-10=-4
-4=-4
true
ANSWER IS D
