X= first integer
21-x= second integer
(x)(21-x)= 108
multiply x by each term in parentheses
21x - x^2= 108
subtract 108 from both sides
21x - x^2 - 108= 0
-x^2 + 21x - 108= 0
multiply whole equation by -1 to eliminate the negative coefficient in the first term
(-1)(-x^2 + 21x - 108)= 0
x^2 - 21x + 108= 0
factor (remember we need #s to add to 21 and multiply to 108)
(x-12)(x-9)= 0
x-12= 0
x= 12
x-9= 0
x= 9
CHECK:
9 + 12= 21
9 * 12= 108
ANSWER: The two positive integers that add to 21 and multiply to 108 are 12 and 9.
Hope this helps! :)
Hope this helps! You need to take two points on the line and use the slope formula to find the slope. To find the y-intercept, look for the point that touches the y-axis.
Answer:-20
Step-by-step explanation:
To invert just flip the two numbers. So the inverse of 2,5 would be 5,2, and the inverse of 9,-1 would be -1,9, and so on.
ANSWER
False
EXPLANATION
The tangent function has no amplitude because it is not bounded.
The given tangent function is
This is of the form
f(t)=a tan(bt)
The period is given by
The first statement is true but the second is false.
Hence the whole statement is false.
