6 I .
5 I .
4 I .
3 I . . .
2 I . . . .
1 I . . . . .
3 4 5 6 7 8
Step-by-step explanation:
left side is the frequency bottom is the number of books
put one dot for the frequency of the books
-3
4x+1=2x-5
-1 -1
4x= 2x-6
-2x -2x
2x=-6
/2 /2
x=-3
B. The statement is true because if the degree of the numerator of a rational function equals the degree of the denominator, then the rational function has a horizontal asymptote that is equal to the ratio of the leading coefficients.
2y + 4 + x = 90
2y + 4 + 3y + x = 180
5y + x + 4 = 180
x = 176 - 5y
2y + 4 + (176 - 5y) = 90
-3y + 180 = 90
-3y = -90
y = 30
x = 176 - 5(30)
x = 26 degrees
Hope this helps! :)
