Answer:
Step-by-step explanation:
Let
x -----> the number of minutes
y ----> the balloon's height in feet
we know that
The linear equation in slope intercept form is equal to
where
m is the slope
b is the y-coordinate of the y-intercept
In this problem we have that
The slope is equal to
----> is negative because is a decreasing function
Remember that the y-intercept is the value of y when the value of x is equal to zero
In this context the y-intercept is the height of the balloon when the time is equal to zero (initial height)
substitute
12% of 120 is 14.4
Change the percentage into a decimal by dividing over 100:
12 / 100 = 0.12
Multiply:
0.12 × 120 = 14.4
For this case we have the following expression:
5x3 + 40y6
Common factor 5:
5 (x3 + 8y6)
Factoring the expression within the parenthesis we have:
5 ((x + 2y2) (x2 - 2xy2 + 4y4))
Answer:
The factored expression is given by:
5 ((x + 2y2) (x2 - 2xy2 + 4y4))
Answer: d) x+y =40
x=2y -11

Answer: The answer is given below
Step-by-step explanation:
From the question, James has a lot of games while his friend Samuel, has 4 times as many games as James.
Let the number of games James has be represented by g.
Since Samuel has 4 times as many games as James, then Samuel's game will be:
= 4 × g
= 4g
The expression for James is g.
The expression for Samuel is 4g.
