Do you think than i ve understood it right
3x+9=30
3x=21
x = 21/3 = 7
x = 7
hope helped
Step-by-step explanation:
4/9A = 12
A = 12×9/4
= 27
......
Since the amount of money earned is based of of the amount of pies he sells...
y = 14x
Hope this helps!
The correct answer is B) y + 9 = 2(x - 1)
In order to find this, simply take the point and the slope and plug into the base form of point-slope form.
y - y1 = m(x - x1)
Use the slope for m and the point for (x1, y1)
y + 9 = 2(x - 1)
