Answer:
(2, -4) would be point b.
Step-by-step explanation:
This is because -2 was on the negative side of the x axis before the refection and now it's on the positive side of the x axis
1*2*3*4*5*6 + 1*2 = 720 + 2 = 722
<u>Corrected Question</u>
I am donating packages for Christmas drive. After the first week, I spent 126 to donate three children packages and 8 adult packages. After two weeks I spent 108 to donate six children packages and 4 adult packages. What is the price of each type of package
Answer:
Adult package costs $12
Child's package costs $10.
Step-by-step explanation:
Let the cost of a child's package =c
Let the cost of an adult package =a
<u>First Purchase</u>
Cost of three children packages and 8 adult package=$126
<u>Second purchase</u>
Cost of six children packages and 4 adult packages=$108
6c+4a=108
Multiply this equation by 2 to make the coefficient of a the same as the other equation
We solve the two resulting equations simultaneously
Subtract
-9c=-90
Divide both sides by -9
c=10
Substitute c=10 into 3c+8a=126 to solve for a
3(10)+8a=126
8a=126-30
8a=96
Divide both sides by 8
a=12
Therefore, an adult package costs $12 while a child's package costs $10.
5x + 3y= 8.50
3x + 2y= 5.25
Lydia is the first equation. She bought 5 pounds of apples which is x and bought 3 pounds of bananas which is y. Basically, remember each banana and apple weighs a price per pound. We don't know the price so we just put an x. This is the same for the second equation
