How are solutions, roots, and x-intercepts of a quadratic related?

Step-by-step explanation:

The quadratic equation

The roots of quadratic equation is defined as that value when we substitute in the quadratic equation then we get zero.

Solution of quadratic equation is defined as that value of roots which substitute in the equation then we get zero.

x-intercept of the quadratic equation is defined as that  real  value of x on the x- axis  when we substitute in the equation then the value of equation becomes zero.

From the above definitions we can see that roots of quadratic equation can be imaginary or real but x- intercept value of equation is always a real value.

Solution is also called the value of roots but x- intercept is equal to roots when the value of roots is real.

Now, we can says that roots and solutions of quadratic equation are same when values of roots are real. But when the roots are imaginary then we can not find x- intercept in cartesian   coordinate plane .

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

after simplifying it i got: -36.25 as my answer. hope that !
