3x^2 Integrate you add one to the power and divide by that number. In this case:3x^2 = (3x^3)/3 = x^3

boys' total = 70 x 15 = 1050 girls' total = 82 x 10 = 820 Total = 1870 mean = 1870/ 25 = 74.3

Accent marks, or 'tildes' can be tricky in Spanish, and in some cases they are just diacritical marks, meaning they indicate that two words have different meanigs as in 'más' (more) and 'mas' (but). Howev...

identify what the question is asking -> both translation rules and expansion of bracketstranslation rule --> translation of 3units left on x-axis actually gives a the graph of y=(x+3)^2 -1. This is ...

Add the 2 eqns together to eliminate the y's to give: 4x=4. Divide by 4 to give x=1Now substitute x=1 into the first eqn: 3+2y=7. Subtract 3 from both sides -> 2y=4. Divide by 2 to give y=2.Now, check ...
