Answer:
x=3
Step-by-step explanation:
3(2x+5)=4x+21
6x+15=4x+21
-4x -4x
2x+15= 21
-15 -15
2x=6
2 2
<h2>x=3 Hope that helped!!!!</h2>
In the equation mx+b, change m, since the variable m represents the slope of the line.
At x = -2, there is a blue dot, which is a local minimum, because it is below the x axis.
The dot is located at y = -4
The answer is Yes there is a local minimum at x = -2
The local minimum is y = -4
The solution to the equation is (325, 404) which is the point of intersection.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let x represent the number of student tickets and y represent the number of adult tickets.
It is given by the equation:
- x + y = 729 (1)
- 3x + 5y = 2995 (2)
The solution to the equation is (325, 404) which is the point of intersection.
