So before we can decide which graph it is, we have to find the zeros (x-intercepts) of this graph. We can do this by setting y to 0.
Firstly, factor out 3x on the right side of the equation: 
Next, use the zero product property to solve y = 0:


So we know that the zeros of this equation are (4,0) and (0,0). Looking at the four graphs, the only graph that has a line crossing those 2 points is the first graph. Therefore, the graph of this equation is the first graph.
Answer:
Carl's checked bags way 15.5 kilograms each.
Step-by-step explanation:
35-4=31 -> 31÷2=15.5
Can't help unless you give us the plotted points of ABC,
Answer:
x= 30 degrees
Step-by-step explanation:
This is an isosceles triangle as indicates by the lines on the sides.
Since the sides lengths are equal, the base angles are equal
x= 30 degrees
