For this case, the first thing we must do is define a variable.
We have then:
n: number of days.
We now write the explicit formula that represents the problem.
We have then:
an = 4n + 15
Where,
15: crunches the first day
4: increase the number 4 each day
Answer:
An explicit formula for the number of crunches Abbie will do on day n is:
an = 4n + 15
Answer: The equation in slope intercept form is
y = 2x/5 + 4/5
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = y intercept
m represents the slope of the line.
The given equation is expressed as
2x - 5y + 4 = 0
Adding 5y to the left hand side and the right hand side of the equation, it becomes,
2x - 5y + 5y + 4 = 5y
5y = 2x + 4
Dividing the left hand side and the right hand side of the equation by 5, it becomes,
5y/5 = 2x/5 + 4/5
y = 2x/5 + 4/5
Answer:
This equation has no solutions. So your answer is the last one!
Step-by-step explanation:
Answer:
-6x⁴y - 2x³y² + 9x²y³ - 3xy⁴ + y⁵
Step-by-step explanation:
(–2x³y² + 4x²y³ – 3xy⁴) – (6x⁴y – 5x²y³ – y⁵)=
–2x³y² + 4x²y³ – 3xy⁴ – 6x⁴y + 5x²y³ + y⁵=
-6x⁴y - 2x³y² + 9x²y³ - 3xy⁴ + y⁵
