Equation in vertex form, y= (-1/4) x² + 4
<u>Step-by-step explanation:</u>
we have the equation,
y = ax² + 4 ( we need to find "a")
Now we have,
2 = a(4)2 + 4
2 = a (8)+ 4
2-4 = 8a
-2= 8a
a= -1/4
Substituting the value of "a" in the equation, we have
y = (-1/4)(x- 0)² + 4 (or) y= (-1/4) x² + 4
The parabola is opens downward. Therefore the vertex is above the x-axis and then the parabola passes through a point below the x-axis.
Equation in vertex form= y= (-1/4) x² + 4
Answer: Anothony delivers 48 milk boxes a week.
Step-by-step explanation:
12 x 4 = 48
Standard form is
ax+by=c
get all x and y on one side
first distribute
-1(x-y)=-x+y
now weh have
8-x+y=-3x+5
add 3x to both sides
8+2x+y=5
minus 8 from both sides
2x+y=-3
Answer:
Step-by-step explanation:
Hi there!
Since we are given the slope and the y-intercept of the line, we can very easily identify the equation of the line.
Slope-intercept:
y=mx+b
Plug in the values:
Thus, is the equation of the line.
Hope it helps! Enjoy your day!
