Answer:
Step-by-step explanation:
The graph in the attachment is a quadratic function whose vertex is in the fourth quadrant.
The coordinates of a point in the fourth quadrant is of the form 
Considering the options, the vertex must have coordinates 
and 
.
The quadratic function in vertex form is written as;
Therefore the equation of the quadratic function is;
The correct answer is option D
60 is my resultados of area
Answer:
B. 3x + y = 4
Step-by-step explanation:
y = -3x + 4
Check:
3x + y = 4
<u>-3x -3x</u>
y = -3x + 4
Answer:
y= 2/3x +1
Step-by-step explanation:
The y intercept is 1 It crosses the y axis at 1. So the point is (0,1)
Another point on the line is (3,3)
We can calculate the slope
m = (y2-y1)/(x2-x1)
= (3-1)/(3-0)
=2/3
The equation for a line is y=mx+b where m is the slope and b is the y intercept
y= 2/3x +1
So he bought the $120 game with $82 and 2 equally priced game. This can be changed to an equation: 120= 82+2X. The X represents the cost of the used game.
120= 82+2X
-82 -82
——————-
38= 2X
38= 2X
Divide by 2 on both sides
X= 19
