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:
70 decreased by 20% = 56
Absolute change (actual difference):
56 - 70 = - 14
Step-by-step explanation:
The value of x in the diagram is 15° and the value of y is 6°

The figure given is a triangle. A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees
The first step is to determine the value of x.
The value of x can be determined using the exterior angle.
The sum of the two interior opposite angles in a triangle is equal to the external angle
(4x - 7)° + 86° = (9x + 4)°
Combine similar terms
9x - 4x = 86 - 7 - 4
5x = 75
x = 15°
To determine the value of y, first substitute for the value of x in the angle (4x - 7)°
(4x - 7)° = (4x15) - 7 = 53°
The sum of angles in a triangle add up to 180°
53° + 86 + (7y - 1) = 180°
add like terms
138 + 7y = 180
7y = 42
y = 6°

Answer: 254.34 ^ 2
Step-by-step explanation:
To find the area of the circle use its formula
A = Pi * R^2 / Area equals pie times radius squared
The two circles diameter combined is 18 meaning the radius is 9
So we plug 9 into the formula
A = 3.14 * 9^2
A = 3.14 * 81
A = 254.34 ^ 2
