Answer:

The inequality $\frac{8}{4}\:$ is true.

Step-by-step explanation:

Given

$\frac{8}{5}$

FALSE

Reason: 8/5 or 1.6 is greater than 9/10 or 0.9

$1>\frac{6}{5}$

FALSE

Reason: 1 is smaller than 6/5 or (1.1)

$\frac{5}{2}$

converting mixed number to improper fraction

$\frac{5}{2}$

FALSE

Reason: 5/2 can not be less than 5/2

$\frac{8}{4}\:$

$2$

TRUE

Reason: 2 is indeed smaller than 5/2 or 5.2 ∵ 5/2 = 2.5

Therefore, inequality $\frac{8}{4}\:$ is true.

3) Solve each equation using the quadratic formula. Show<br> a. x2 – 3x – 10 = 0

Naya [18.7K]

Answer:

Step-by-step explanation:

The quadratic formula of a quadratic equation

$ax^2+bx+c=0\\\\\text{If}\ b^2-4ac>0\ \text{then the equation has two solutions}\ x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

$\text{If}\ b^2-4ac=0\ \text{then the equation has one solution}\ x=\dfrac{-b}{2a}$

$\text{If}\ b^2-4ac$

We have:

$x^2-3x-10=0\to a=1,\ b=-3,\ c=-10\\\\b^2-4ac=(-3)^2-4(1)(-10)=9+40=49>0\\\\x=\dfrac{-(-3)\pm\sqrt{49}}{2(1)}=\dfrac{3\pm7}{2}\\\\x=\dfrac{3-7}{2}=\dfrac{-4}{2}=-2\\or\\x=\dfrac{3+7}{2}=\dfrac{10}{2}=5$
