<em><u>Question:</u></em>
Find the sales price of the following item.
A camera originally costing $139.99, marked down $18.50
<em><u>Answer:</u></em>
The sales price of camera is $ 121.49
<em><u>Solution:</u></em>
Given that a camera originally costing $139.99, marked down $18.50
Therefore,
Original cost of camera = $ 139.99
Markdown price of Camera = $ 18.50
We have to find the sales price of camera
Use the following formula:
Sales price = Original cost of camera - Markdown price of Camera
Substituting the values, we get
Sales price = 139.99 - 18.50
Sales price = 121.49
Thus sales price of camera is $ 121.49
The value of the function is 5
<h3>What is function?</h3>
A function is defined as a relation between a set of inputs having one output each.
Given function:
f(x) = 5x − 6
Now f(2+h) - f(2) /h
= 5(2+h)-6 - 10+6/h
=10+ 5h -10/h
=5h/h
=5

Answer:
65 tickets for children
Step-by-step explanation:
In this case we can solve it by means of a 2x2 system of equations, like this:
Let x be the ticketsr of children
let y be the tickets of adults
Thus:
5.3 * x + 9.4 * y = 852.1
x + y = 119 => x = 119 - y
replacing, we are left with:
5.3 * (119 - y) + 9.4 * y = 852.1
630.7 - 5.3 * y + 9.4 * y = 852.1
9.4 * y - 5.3 * y = 852.1 - 630.7
4.1 * y = 221.4
y = 221.4 / 4.1
y = 54
Now to calculate x:
x = 119 - 54
x = 65
Which means that there are 65 tickets for children and 54 tickets for adults.
Answer:
x-int: (8/3, 0)
y-int: (0, -32/3)
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
x-intercept is the x-value when y = 0
y-intercept is the y-value when x = 0
Step 1: Write equation
2x - 1/3 = 1/2y + 5
Step 2: Subtract 5 on both sides
2x - 16/3 = 1/2y
Step 3: Multiply 2 on both sides
4x - 32/3 = y
Step 4: Rewrite
y = 4x - 32/3
Step 5: Find x-int
0 = 4x - 32/3
32/3 = 4x
x = 8/3
(8/3, 0)
Step 6: Find y-int
y = 4(0) - 32/3
y = 0 - 32/3
y = -32/3
(0, -32/3)
