The first steps would be something along the lines of...

Combine like terms
2x and 3x 
-1 and 4 
Here is how to work the problem, 

3x -1 = 2x +4 
The goal is to get X alone, 
So Combine like terms by subtracting 2x from 3x 
and Adding 1 to 4 
Now you have 
x = 5

Which statement is true about 7/10 and 2/6?
77julia77 [94]

Answer: The third answer

Step-by-step explanation:

7/10 is 0.7 and 2/6 is 0.33, 2/6 would be less than 1/2 because 1/2 is 0.5, 0.7 is greater than that benchmark

Use the Quadratic Formula to solve x2 + 20x + 98 = 0
Lubov Fominskaja [6]
ax^2+bx+c=0\\\\\Delta=b^2-4ac\\\\if\ \Delta \ \textless \  0\ then\ no\ solution\\\\if\ \Delta =0\ then\ one\ solution\ x_0=\dfrac{-b}{2a}\\\\if\ \Delta \ \textgreater \  0\ then\ two\ solutions\ x_1=\dfrac{-b-\sqrt\Delta}{2a}\ and\ x_2=\dfrac{-b+\sqrt\Delta}{2a}\\-----------------------------

x^2+20x+98=0\\a=1;\ b=20;\ c=98\\\\\Delta=20^2-4\cdot1\cdot98=400-392=8 \ \textgreater \  0\\\sqrt\Delta=\sqrt8=\sqrt{4\cdot2}=\sqrt4\cdot\sqrt2=2\sqrt2\\\\x_1=\dfrac{-20-2\sqrt2}{2\cdot1}=\dfrac{-20-2\sqrt2}{2}=-10-\sqrt2\\\\x_2=\dfrac{-20+2\sqrt2}{2\cdot1}=\dfrac{-20+2\sqrt2}{2}=-10+\sqrt2

[calculus] the distance from the point (6, -4) to the circle <img src="https://tex.z-dn.net/?f=x%5E2%2By%5E2-8y%3D0" id="TexForm
stealth61 [152]

Answer:

Option C.

The distance from the point to the circle is 6 units

Step-by-step explanation:

we know that

The distance between the circle and the point will be the difference of the distance of the point from the center of circle  and the radius of the circle

step 1

Find the center and radius of the circle

we have

x^{2} +y^{2}-8y=0

Convert to radius center form

Complete the square

x^{2} +(y^{2}-8y+16)=0+16

Rewrite as perfect squares

x^{2} +(y-4)^{2}=16

so

The center is the point (0,4)

The radius is

r^{2}=16\\r=4\ units

step 2

Find the distance of the point from the center of circle

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

(6,-4) and (0,4)

substitute the values

d=\sqrt{(4+4)^{2}+(0-6)^{2}}

d=\sqrt{(8)^{2}+(-6)^{2}}

d=\sqrt{100}\ units

d=10\ units

step 3

Find the difference of the distance of the point from the center of circle  and the radius of the circle

10\ units-4\ units=6\ units

therefore

The distance from the point to the circle is 6 units

see the attached figure to better understand the problem
