<span>A word problem that can be modeled by addition of two negative numbers integers is given as followed.
Evans and Irvin are standing at the same spot. Evans took 7 steps backwards and another 7 steps backward, what is the current position of Evans relative to where Irvin is standing?
To solve the above, we note that Evans </span><span>took 7 steps backwards and another 7 steps backward, thus his current position relative to Irvin is given by (-7) + (-7) = -7 - 7 = -14.
Therefore, Evans is 14 steps backwards relative to where Irvin is standing.

Answer:
a) y = 2x⁴ -18x² +8x +24
b) 4th degree; tends toward +∞ when |x| gets large
Step-by-step explanation:
a) When r is a root of the polynomial, (x -r) is a factor. The given roots mean the factors are ...
y = a(x -(-1))(x -(-3))(x -2)(x -2) = a(x+1)(x+3)(x-2)²
The product of the constant terms is a(1)(3)(2²) = 12a. This is the y-intercept, which is said to be 24. So ...
12a = 24 ⇒ a = 2
The polynomial function is then ...
y = 2(x +1)(x +3)(x -2)²
y = 2x⁴ -18x² +8x +24
__
b) The leading coefficient of this 4th-degree polynomial is positive, so when x has large positive or negative values, the function value will tend toward positive infinity.
Answer:
The average heart beats approximately 31557600 times a year.
Step-by-step explanation:
60 x 60 = 3600 beats per hour
3600 x 24 = 86400 beats per day
86400 x 365.25 = 31557600 beats per year
