The first one IS a function. The rest are not.
Y = mx + b
slope(m) = 3/4
(3,7)...x = 3 and y = 7
now we sub and find b, the y int
7 = 3/4(3) + b
7 = 9/4 + b
7 - 9/4 = b
28/4 - 9/4 = b
19/4 = b
so ur equation is : y = 3/4x + 19/4
if point A (x,5) lies on the line.....
y = 3/4x + 19/4......when y = 5
5 = 3/4x + 19/4
5 - 19/4 = 3/4x
20/4 - 19/4 = 3/4x
1/4 = 3/4x
(1/4) / (3/4) = x
1/4 * 4/3 = x
4/12 reduces to 1/3 = x......so point A is (1/3,5)...with x being 1/3
Answer:
C
Step-by-step explanation:
Everything else can be simplified to 2/5, except for 9/20
It states that the chef makes 20.5 servings, and that each serving holds 3.275 ounces, so to find the total amount of sauce the chef made you would multiply the number of servings by the volume of each serving, which is 20.5*3.275= 67.1375
There are four decimal places in the product of 67.1375 total ounces of sauce.
Answer: $440
Step-by-step explanation:
Given selling price = $ 372
Loss % = 7%
We know, cost price = selling price × 100/100 - loss%
Therefore, cost price = 372 × 100/100 - 7
= 372 × 100/93
= $400
Now cost price = $400
Gain% = 10%
Therefore, selling price = (100 + gain%)cost price/100
= (100 + 10)400/100
= 110 × 4
= $440
