Answer: $3.75
Step-by-step explanation: $15x15=225/60= 3.75
For this case, the first thing we must do is define variables.
We have then:
t: the time in minutes
k: the number of kilometers
The relationship between both variables is direct.
Therefore, the function is:
Where, "c" is a constant of proportionality.
To determine "c" we use the following data:
After running for 18 minutes, she completes 2 kilometers.
Substituting values:
Clearing c we have:
Then, the equation is given by:
Answer:
An equation that can be used to represent k, the number of kilometers Julissa runs in t minutes is:
Answer:
1. y= |x| -15
2. y = -|x| +3
Step-by-step explanation
.The V shape means absolute value (the | | ), since its upside down, the equation has to be negative. The tip of the V doesn't start at 0 like normal, it's up 3, so the equation has a +3 at the end. The x intercept at (3, 0) is just so you can check your work. If we plug in 3 for x, we do in fact get 0 for y.
Not sure, if correct but here.
3(2x + 6)
using the distributive property
= 3 * 2x + 3 * 6
= 6x + 18
Answer: 6x + 18
[ ? ] = 18
Answer:
m^2+m+1
Step-by-step explanation:
- m^3 - 1= (m-1)(m^2+m+1)
- m^4 + m^2 + 1= m^4+2m^2+1 - m^2= (m^2+1)^2 -m^2= (m^2+m+1)(m^2-m+1)
- m^2+ m + 1
HCF= m^2+m+1 which is the factor of all three polynomials
