Answer:
y = 2
Step-by-step explanation:
x + 5y - 10 = 0
X = 4y - 8
since x is given as = 4y - 8 we can use this in first equation
replace x with 4y - 8
x + 5y - 10 = 0 ➡ 4y - 8 + 5y - 10 = 0 add like terms
9y - 18 = 0 add 18 to both sides of the equation
9y = 18 divide both sides by 9
y = 2
Answer:
- domain: [0, ∞)
- range: (-∞, ∞)
- not a function
Step-by-step explanation:
The arrows indicate the graph continues indefinitely in the direction indicated.
The domain is the horizontal extent, so is the interval from 0 to infinity, including 0.
The range is the vertical extent, so extends from negative infinity to positive infinity (all real numbers).
The graph does not pass the vertical line test: a vertical line intersects it in more than one place, so the relation is NOT a function.

The relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.
<h3>What is relative frequency?</h3>
The relative frequency of an event is the ratio of total number of favorable or desired outcome to the total number of trails done.
Given information-
The card is selected random from the deck of cards.
Total number of trails is 40.
It is known that the total number of diamond card in a standard deck of card is 11. There is total 40 trials is done in which a random card is selected.
As the relative frequency is the ratio of total number of diamonds to the total number of trials done. Thus,

In the percentage from,

Thus the relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.
