Answer:
that puts the solution in the form ...
variable is ...
Step-by-step explanation:
It isn't always.
__
Often, we like to have a solution be in the form ...
variable is ...
So, for an inequality, that puts the variable on the left:
x > 3
y < 27
__
Personally, I like to see the answer in a form that has the variable and its values in the same relation as on a number line. This means, my preferred inequality symbols are < or ≤, since those have the smaller numbers on the left. I would write the first example above as ...
3 < x
showing that the shaded portion of the number line (representing possible values of the variable) is to the right of the open circle at 3. For me, it is more mental effort to translate x > 3 to the same image.

The forms we choose to use are all about making communication as easy as possible.
Answer:
£72000
Step-by-step explanation:
According to the Question,
- Given, At a football game, the ratio of men to women is 4:1 & There are 9,000 people in total
Thus, 5 ⇒ 9000 People
So, 4 ⇒ 7200 People(Men)
1 ⇒ 1800 People(Women)
- And, each ticket costs £10
Thus, The amount of money made from tickets sold to men is 7200 total Men x £10 Per Ticket Cost ⇒ £72000.
Answer:
Step-by-step explanation:
y = k*x This is the formula for a direct variation.
- y = 20
- x = 4 Substitute these values into the direct variation
20 = 4 * k Divide by 4
20/4 = 4k/4
k = 5
Answer: the constant of variation is 5
The expression that represents the profit is: ( 5x2 + 2x – 80)-(<span>5x2 – x + 100)
