Answer:
Option a. $300
Step-by-step explanation:
Let
x ----> the cost of the rent monthly per person
we know that
The number of persons is 3 (Sal and two friends)
The cost of the security deposit per person is equal to
If Sal paid a total of $1,000 to move in
then
That means that the cost per person of two months of rent (first and last month) plus $400 (security deposit per person) must be equal to $1,000
solve for x
Answer:
21 pieces of chickens.
Step-by-step explanation:
Given:
The farmer has a total of 40 animals. ( cows and chicken )
He counts the legs of all his animals and realizes he has a total of 118 legs.
Question asked:
How many chickens does the farmer have ?
Solution:
Let number of chickens =
Then number of cows =
Now, as here given that total number of legs are 118 of all the animals, and as we know that a chicken has two legs and cow has four legs, hence the equation will be :
<u>Total number of legs = Number of legs having chickens + Number of legs having cows</u>
Subtracting both sides by 160
By adding both sides by minus
By dividing both sides by 2
Hence, farmer have 21 pieces of chickens.
The x-intercepts and the y-intercepts of the function is that determines the graph is:
The function of an absolute equation can be graphed by determining the values of x-intercepts and the y-intercepts of the function.
From the given equation:
y = 2|x+3| - 4
To determine the y-intercepts, we need to set the values of x to zero, and vice versa for x-intercepts.
By doing so, the x-intercepts and the y-intercepts of the function is:
Therefore, since we know the x and y-intercepts, the graph of the absolute value can be seen as plotted below.
