Let the fare of adults be 'x' and that of children be 'y'
Equation Formation.
3 x + 4 y = 87................ equation (i)
2 x + 3 y = 62................ equation (ii)
3 x +4 y = 87 ..............×2
2 x +3 y = 62...............×3
6 x + 8 y = 174
6 x + 9 y = 186
y = 12
2 x = 62 - 3 y
2 x = 62 - 36
2 x = 26
x =13
Answer = adults ⇒ $13
children ⇒$ 12
Answer:
x=4
Step-by-step explanation:
<em>Multiply by 2 from both sides of equation.</em>
<em>2x/7-5=2*2</em>
<em>Simplify, to find the answer.</em>
<em>2*2=4</em>
<em>x=4 is the correct answer.</em>
<em>I hope this helps you, and have a wonderful day! </em>
Answer:
140
Step-by-step explanation:
The arithmetic series is 5, 7, 9, 11, ........., 23.
First u have to determine the no. of terms that can be done by using
Tₙ = [a + (n - 1)d]
Tₙ-------nth term
a---------first term
n---------no.of terms in the series
d---------common difference
here a = 5,d = 2.
let it contain n terms Tₙ= [a + (n-1)d]
Substitute Tₙ, a, and d in the equation
23 = 5 + (n - 1)2
Subtract 5 from each side.
18 = (n-1)2
Divide each side by 2
(n - 1) = 9
Add 1 to each side
n = 9 + 1 = 10
The sum of the arithmetic sequence formula: Sₙ= (n/2)[2a+(n-1)d]
Substitute Sₙ, a, n and d in the equation
Sₙ= (10/2)[2(5) + (10-1)2]
Sₙ= (5)[10 + (9)2]
Sₙ= 5[10 + 18]
Sₙ= 5[28] = 140
Therefore the sum of the arithmetic sequence is 140.
Cubic Function Form:
y=
However here we only need ax^3 and +d
ax^3 makes the graph wider or skinnier or reflects it if negative.
So the first coefficient will be negative since we want to reflect it along the x axis
To move left three we will have to add 3 to the ax^3 giving us something like (x+3)^3
To move up 5 we set our y intercept (the +d part) to d=5.
Combing everything together gives us (x+3)^3+5
