What is the factored form of 3x + 21x-24?
1 answer:
Answer:
factorize form of the equation is , where
Step-by-step explanation:
Given Equation:
Adding the terms of 'x' and taking constants on the other side.
The sign of the constant will change on changing the side of it.
So, the value of 'x' is 1
The factorized form of the equation can be made by taking the common value from the equation i.e

Answer:
Step-by-step explanation:
Given:
The level of a lake is falling linearly.
On Jan 1, the level is 452 inches
On Jan 21, the level is 378 inches.
Now, a linear function can be represented in the form:
Where, 'm' is the rate of change and 'b' is initial level
So, let Jan 1 corresponds to the initial level and thus b = 452 in
Now, the rate of change is given as the ratio of the change in level of lake to the number of days passed.
So, from Jan 1 to Jan 21, the days passed is 21.
Change in level = Level on Jan 21 - Level on Jan 1
Change in level = 378 in - 452 in = -74 in
Now, rate of change is given as:
Hence, the function to represent the lake level is
Where, 'x' is the number of days passed since Jan 1.
