Y=3x+7
this equation is in slope- intercept form (y=mx+b), so to translate up or down you add or subtract however many units you are translating to the b of the equation.
23.
3•(-3)^2-4
3•(-3)^2
Exponents first.
-3^2=9
3•9=27
27-4= 2:.
The answer is 18 inches.
Let r=radius and d=diameter
2r=d
2(9)=d
18=d
Hope this helps!
