The incorrect inequality is g > 80. The symbol ">" means greater than. So g > 80 would translate to meaning Kyle's grandmother is greater than 80. However, the problem states that his grandmother is not more than 80, meaning she is either 80 or younger. So the inequality should be g ≤ 80, or Kyle's grandmother is less than or equal to 80 years of age.
Answer:
8
Step-by-step explanation:
The function u given me is

The period of a function is represented by

where b is the coefficient of the x variable.
The coefficient is pi/4 so

8 is the answer.
2x^2-15=x
2x^2-x-15=0
(X-3)(2x-5)=0
x-3=0 or 2x-5=0
X=3 2x=5
x=5/2=2.5
<span>(a^2+b^2)^2
since (a+b)^2=a^2+2ab+b^2, substitute a with a^2 and b with b^2, which yields:
a^4+2(a^2*b^2)+b^4</span>
Dance (D) + Rap (R) + Country (C) = 1,075 songs
D = 3R
C = R + 105
RAP
Subtract 105 from both side:
(3R) + R + (R + 105) = 1,075
-105 -105
Combine all R's:
(3R) + R + R = 970
5R = 970
Divide both sides by 5:
5R = 970
/5 /5
R = 194
DANCE
D = 3(R)
D = 3(194)
D = 582
COUNTRY
C = R + 105
C = 194 + 105
C = 299
So, the DJ has a total of 194 rap songs, 582 dance songs, and 299 country songs.
