Y = abˣ
(a ≠ 0, b ≠ 0)
(1, 7.5)
x = 1
y = 7.5
↓
7.5 = ab
(3, 16.875)
x = 3
y = 16.875
↓
16.875 = ab³
7.5 = ab
b b
7.5/b = a
16.875 = ab³
b³ b³
16.875/b³ = a
7.5/b = 16.875/b³
7.5/b(b³) = 16.875/b³(b³)
7.5b² = 16.875
7.5 7.5
b² = 2.25
√(b²) = √(2.25)
b = 1.5
a = 7.5/b
a = 7.5/1.5
a = 5
y = 5(1.5)ˣ
32+45 can be used to figure out the starting amount
2x + 50 > = 100 (thats greater then or equal)
2x > = 100 - 50
2x > = 50
x > = 50/2
x > = 25
minimum number is 25
The number of presale tickets sold is 271
<em><u>Solution:</u></em>
Let "p" be the number of presale tickets sold
Let "g" be the number of tickets sold at gate
<em><u>Given that, total of 800 Pre-sale tickets and tickets at the gate were sold</u></em>
Therefore,
Presale tickets + tickets sold at gate = 800
p + g = 800 ------ eqn 1
<em><u>Given that, number of tickets sold at the gate was thirteen less than twice the number of pre-sale tickets</u></em>
Therefore,
Number of tickets sold at gate = twice the number of pre-sale tickets - 13
g = 2p - 13 ------- eqn 2
<em><u>Let us solve eqn 1 and eqn 2</u></em>
Substitute eqn 2 in eqn 1
p + 2p - 13 = 800
3p -13 = 800
3p = 800 + 13
3p = 813
p = 271
Thus 271 presale tickets were sold
Answer:
3
Step-by-step explanation:
to find side length of squares take square root of areas
first square side length: 9
second square side length: 6
difference between 9 and 6 is subtraction, 9-6=3
