Answer:
Baseballs is: $10
Bats is: $4
Step-by-step explanation:
Let x represent bats
and y represent baseballs
So we have :
(1) 4x + 7y = 68
(2) x + y = 14 => y = 14 - x
Use substitution.
Substitute equation (2) into equation (1)
4x + 7(14 - x) = 68
Solve for x
4x + 98 -7x = 68
-3x + 98 = 68
-3x = -30
x = 10
Solve for y, replace x = 2 into equation (2)
y = 14 - 10 = 4, so y = 4
Since x represents bats and y represents baseballs, it cost $10 for the bats and $4 for the baseballs.
$7.87+$46.32=$54.19. If you multiply 46.32 by 0.17, 17%, it is 7.87 so you just add that to the original bill, 46.32
Original length: x
original width; x-3
original area: x(x-3)
when the dimensions doubles, that is, increase by a factor of 2, the area increase by 2²
4[x(x-3)]
4x(x-3)=4x²-12x
you can also do it this way:
original length: x doubled: 2x
original width; x-3 doubled: 2(x-3)
new area: 2x[2(x-3)]= 4x²-12x
K would be the the y-coordinate of the vertex. It also determines the translation. If k is greater or less than zero, the function will translate up or down (up if K is positive and down if K is negative).
Answer:
Basketball 300
Football 100
Baseball 50
Soccer 150
Step-by-step explanation:
Half of the students would choose basketball
so 600/2 = 300
Half of the remaining students would choose soccer
so 300/2 = 150
2/3 of the remaining students would choose football
so 150 x 2/3 = 100
1/3 of the remaining students would choose baseball
150 x 1/3 = 50
