I think the answer is A) 2.
I apologize if this is incorrect
where t is the number of hours worked by Natalle
Here, we want to write an equation that will represent the given scenario
Let the number of hours for which she earned the pay be t
From the question, she earns $11 per hour
So for t hours, the amount earned excluding the tip will be;
Now, let us add the tip and equate to the total amount earned
We have this as;
Answer:
3x + y = -16
Step-by-step explanation:
this is because
5x-2x = 3x
6y-5y = 1y which is written as y
-5 -11 = -16
Step-by-step explanation:
Given data:
ABCD is a quadrilateral.
AD = BC – – – – (1)
∠DAB = ∠CBA – – – – (2)
<u>To prove that BD = AC:</u>
In ΔABD and ΔBAC,
AD = BC (given side)
∠DAB = ∠CBA (given angle)
AB = BA (reflexive side)
Therefore ΔABD ≅ ΔBAC by SAS congruence rule.
By corresponding parts of congruence triangles,
BD = AC
Hence proved.
The line of best fit is a line that follows the direction of the dots. It doesn't have to be perfect, it's just a general line to represent the data. Sometimes there isn't a line of best fit (if there is no correlation). It normally touches most of the dots.
The slope is about 1/2 and the point where the line touches the y axis is at 40 so that means an equation could be y = 1/2x + 40
When the advertising expenditure (x value) is 18,000, substitute it into the equation above. y = 1/2(18,000) + 40 which equals y = 9,040 . This is the expected revenue.
Hope this helps!
