Kobotan [32]

Answer:

x=5

Explanation:

We need to get x to stand by itself on one side of the equation.

4x-2 = 3x+3 ← add 2 to each side

4x = 3x+5 ← subtract 3x from each side

x = 5 ← final answer

The radius of a basketball hoop is 9 inches. Which expression can be used to find the hoop's circumference in inches?

Olenka [21]

The right answer is Option D.

Step-by-step explanation:

Given,

Radius of basketball hoop = 9 inches

As the basketball hoop is in circular shape.

Circumference of basketball hoop = 2πr

We will put given radius = 9

Circumference of basketball hoop = 2*π*9

Circumference of basketball hoop = 2 . 9 . π

Therefore,

Circumference of basketball hoop is 2*9*π.

The right answer is Option D.

Solve. -7x+1-10x^2=0

telo118 [61]

Answer:

$-7x+1-10x^2=0$

$-10x^2-7x+1=0$

$quadratic\:equation:-$ $ax^2+bx+c=0$

$solutions:-\\\\x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$For \\A=-10\\B=-7\\C=1$

$x_{1,\:2}=\frac{-\left(-7\right)\pm \sqrt{\left(-7\right)^2-4\left(-10\right)\cdot \:1}}{2\left(-10\right)}$

$\sqrt{\left(-7\right)^2-4\left(-10\right)\cdot \:1}=\sqrt{89}$

$x_{1,\:2}=\frac{-\left(-7\right)\pm \sqrt{89}}{2\left(-10\right)}$

$x_1=\frac{-\left(-7\right)+\sqrt{89}}{2\left(-10\right)},\:x_2=\frac{-\left(-7\right)-\sqrt{89}}{2\left(-10\right)}$

$\frac{-\left(-7\right)+\sqrt{89}}{2\left(-10\right)}=-\frac{7+\sqrt{89}}{20}$

$\frac{-\left(-7\right)-\sqrt{89}}{2\left(-10\right)}=\frac{\sqrt{89}-7}{20}$

$x=\frac{\sqrt{89}-7}{20}$
