Answer:
The ordered pair that satisfies this problem is (1, -6); x = 1 when y = -6.
Step-by-step explanation:
Please, rewrite your question as follows:
"Suppose that y varies directly with x and y = 12 when x = -2. What is x when
y = -6?" The " = " sign must be included.
The pertinent proportional relationship is y = kx, where k is the constant of proportionality.
We must find k here. Let y = 12 and x = -2. Then 12 = k(-2), or k = -6.
Then the relationship is y = -6x.
Now let y = -6 and find x: -6 = -6x, or x = 1.
The ordered pair that satisfies this problem is (1, -6)
For this case, the first thing you should do is know that the measurement of a television is given by the diagonal of the television.
Therefore, to find the value of x, we use the Pythagorean theorem.
We have then:
Rewriting we have:
Then the dimensions are given by:
Answer:
the dimensions of the screen are: 33.6* 25.2
7/10 / 3/1
7/10 x 1/3
7/30

The number of months when the gyms cost the same is 5 months.
<h3>When would the cost be the same?</h3>
Total cost of joining the gym = registration fee + (cost per month x number of months)
- Hunkey Heros = $50 + $20m
- Zipity-zapity- zap-that-fat = $70 + $10m
When the gyms costs are the same, the two above equations would be equal to each other:
50 + 20m = 70 + 10m
20m - 10m = 70 - 20
10m = 50
m = 50 / 10
m = 5
