Here, y is a cubic function of x.
When x = 3,
Hence, when x = 3, y = 126.
A number is equal to twice a smaller number plus 3. Yhe same number is equal to twice the sum of smaller number and 1. How many
1 answer:
Answer:
There is no solution to the problem
Step-by-step explanation:
In order to find the solutions to the problem you can write the situation in an algebraic form.
You have that a number is equal to twice a smaller number plus 3. This can be written as follow:
(1)
where x is the number and y is the smaller number
Furthermore, the same number x is equal to twice the sum of the smaller number and 1, which can be written as follow:
(2)
To find the solution you equal the equation (1) with (2), and you solve for y:
You obtain an inconsistency, hence, the situation of the problem does not have solution

Answer:
The coordinates of Jedds house are (-7 , -2)
Step-by-step explanation:
* Lets explain how to solve the problem
- If point (x , y) divide the distance between the two points
and
at the ratio
, then
and
* Lets solve the problem
∵ Hollis house is located at (-1 , 4)
∴ = (-1 , 4)
∵ She can walk in a straight line to get to Jedds house
∵ The restaurant is located at (-3 , 2) and partitions the way from
Hollis house to Jedds house by a ration of 1 : 2
∴ (x , y) = (-3 , 2)
∴ = 1 : 2
- Lets consider that Jedds house is located at
∴
∴
- Multiply both sides by 3
∴
- Add 2 for both sides
∴
∴
∴
- Multiply both sides by 3
∴
- Subtract 8 for both sides
∴
∴ The coordinates of Jedds house are (-7 , -2)
