Base=(180°-vertex)/2=(180-82)/2=98/2=49°
base angles are 49°
So if you divide 78 by six you get 13. 78/6=13
So we want x minus 6 to equal thirteen we have to make x a number that will equal 13 when we subtract 6. So we can just add 13+6 to get 19. And 19-6=13. So x=19, does that make sense?
Answer:
D
Step-by-step explanation:
1. Make it into a y = x equation
y = 9x +7
2. change x to y and y to x
x = 9y + 7
3. Isolate y ( if not possible, use implicit differentiation but here you can)
x-7 = 9y
1/9x-7/9 = y
