X= -7
2+x=-5 if you move the constant to the right side it would be x=-5-2 which equals -7
Answer:
<u>k = 220</u>
Step-by-step explanation:
<u>Proportion of y and x</u>
<u>Given</u> :
<u>Solving</u> :
- 55 = k/4
- k = 55 x 4
- <u>k = 220</u>
Let the equation be:
y = ax^2 + bx + c.
Then, substitue the three points into the equation.
First point: 0 = a0^2 + b0 + c.
So c = 0.
Second point: -2 = a(-1)^2 + b(-1) + c.
So a - b + c = -2.
Third point: 6 = a*1^2 + b*1 + c.
So a + b + c = 6.
We know that c=0 already, so we substitute c=0 into the last two equations and we would get:
a - b = -2
a + b = 6
We add the two equations and we get:
2a = 4
a = 2
Then, we substitute a=2 into a-b=-2 and we get:
-b = -4
b = 4
Now we know a = 2, b = 4, and c = 0
Then, the equation of the parabola would be:
2x^2 + 4x
14720 is answer. or product
Since the value of b is 5, hence the equation of the horizontal line is x = 5
<h3>Equation of a line</h3>
A line is defined as the shortest distance between two points. The given line on the xy plane is a horizontal line.
The equation of a line is expressed as y = mx + b where;
m is the slope
b is the y -intercept
The equation of a horizontal line on the other hand is expressed as x = b
where b is the point where the horizontal line crosses the y-axis.
Since the value of b is 5, hence the equation of the horizontal line is x = 5
