Answer:
The integers are (x, y) = (40, 8).
Step-by-step explanation:
x = 5y
xy = 320
Substitute the first equation into the second equation.
(5y)(y) = 320
5y^2 = 320
y^2 = 64
y = 8 (y must be positive)
The integers are (x, y) = (40, 8).
The player took a total of 70 shots and missed about 28 shots.

Percentage</h3>
Percentage is used in expressing a fraction number or decimal in fraction of 100. It is expressed using the '%' sign.
Given a total shot of 100, since the player took 70% of the shot, hence:
Total shot taken by the player = 70% of 100 = 0.7 * 100 = 70 shots.
Total shot shot missed = (100% - 60%) of 70 = 40% of 70 = 0.4 * 70 = 28 shots.
The player took a total of 70 shots and missed about 28 shots.

Answer:
Step-by-step explanation:
Your exponential formula is in the form y = ab^x. In this form, the coefficient 'a' is the initial value, the y-intercept, the value when x=0. The value 'b' is the growth factor, which is 1 more than the growth rate per increment of x. This problem is asking for the growth rate to be expressed as a percentage.
__
Given p(x) = 78500(1.02^x), we can compare to the exponential function form to see that ...
- a = 78,500
- b = 1.02 = 1 +0.02 = 1 +2%
The value of x is zero in the year 2000, so the population that year is ...
p(0) = a = 78,500
The increase per year is the value of 'b' with 1 subtracted:
growth rate = 2% per year
x correct answers
23 - x incorrect answers
82 = 4x + -1(23 - x) = 3x - 23
105 = 5 x
x = 105/5 = 21
