Answer:
-$150
Step-by-step explanation:
Given:
(I - E) / 12
Where,
I = total income
E = total expenses
I = $52,000
E = $53,800
(I - E) / 12
= (52,000 - 53,800) / 12
= -1,800 / 12
= -150
-$150 shows that Mr. Engle's total expenses exceeds his total income per month with an average of $150
Good evening
Answer:
<em>a) the cost of one apple is €</em><em>0.9</em>
<em>b) the cost of one pineapple is €</em><em>5.4</em>
<em>c) the cost of two pineapples and six apples is €</em><em>16.2</em>
Step-by-step explanation:
Consider P the price of a pineapple
A the price of an apple
A pineapple costs six times as much as an apple means P = 6A
Mum paid €7.20 for one pineapple and two apples means P + 2A = 7.20
then
6A + 2A = 7.20
then
8A = 7.20
then
A = €0.9
Since P = 6A then P = 6×(0.9) = €5.4
the cost of two pineapples and six apples
= 2P + 6A
= 2P + P
= 3P
= 3×(5.4)
= €16.2
Step-by-step answer:
A vertical line test checks for single or multiple intersections with a given relations If there is a maximum of one intersection with the relation at ANY point in the domain of the relation, we can conclude that the relation is a function. If there are multiple intersections of a VERTICAL line with the function, it is not a function.
Here, we see that vertical line test on the relation shown does not produce more than one intersection at any point in the domain of the relation, hence we conclude that the graph shows a function.
An inverse of a function is a reflection of the function about the y=x line. The result is the same as the interchange of the x and y-axes.
Hence a horizontal line test on the inverse of a function gives the same results as a vertical line test of the function itself, and the conclusion is identical to the test given above in paragraph two.
Answer:
His commission is 1642.69
Step-by-step explanation:
31/100=x/5299
Cross multiply
164,264/100=100x/100
1642.69=x
