The percent of increase is 25 percent
Answer:
How long was the ribbon before it was cut?
Step-by-step explanation:
Y=-3x+1
1 raises the y intercept and -3 is the slope that we can see from (0,1) to (1,-2)
This expression does not have an answer. If both sides are multiplied by 2.6, then you receive an equation of 2.6 = 22.1. Since this expression is incorrect, there is no solution.
Hope this helps!
Answer:
To determine the number of real number solutions of as system of equations in which one equation is linear and the other is quadratic
1) Given that there are two variables, x and y as an example, we make y the subject of the equation of the linear equation and substitute the the expression for y in x into the quadratic equation
We simplify and check the number of real roots with the quadratic formula,
for quadratic equations the form 0 = a·x² - b·x + c
Where b² > 4·a·c there are two possible solutions and when b² = 4·a·c equation there is only one solution.
