When you solve an inequality, you should always be extra careful to check that you don't multiply it by a negative number - because if you do, then you have to change the sign!
So here, the mistake is in this step:
−9x≥ −36
x ≥ 1.
you should change the sign to ≥
x≤1!
Answer:The first one
Step-by-step explanation:
V rectangular prism = Area of the base *5
In an isosceles triangle, there are two base angles and 2 sides that are congruent. The other congruent side and base have a 75 degree angle.
Answer:
Step-by-step explanation:
In a quadratic equation, a rule known as Vieta's Theorem tells us that roots 1 and 2 (we'll call them x1 and x2) added up is equal to -b/a, and x1 multiplied by x2 is equal to c/a. because x1-x2 is 6, and x1+x2=-b/a, which is -(-14), or 14, we can use the substitution method to find out the roots of the equation, being 4 and 10. When putting these roots into the equation, we get that 4^2-14(4)+q=0, and 10^2-14(10)+q=0. We can simplify these equations to make -40+q=0, and adding 40 on both sides gets us that q=40.
<u>To recap:</u>
Vieta's Formula:
use substitution to find the roots
enter the roots into the quadratic equation
solve the equation!
Answer: q = 40
