Solve for x 3x^2 - 10 = -5

Mathematics

aleksandr82 [10.1K]4 years ago

Answer:

A

Step-by-step explanation:

given

3x² - 10 = -5 ( add 10 to both sides )

3x² = 5 ( divide both sides by 3 )

x² = \frac{5}{3}

Take the square root of both sides

x = ± \sqrt{\frac{5}{3} } = ± \frac{\sqrt{5} }{\sqrt{3} }

Add 10 to both sides

3x^2 = -5 + 10

Simplify -5 + 10 to 5

3x^2 = 5

Divide both sides by 3

x^2 = 5/3

Take the square root of both sides

x = √5/3

Simplify √5/3 to √5/3

<em>x = ±√5/3</em>

<u>Answer: A. x = ±√5/3</u>

What is the point slope form of Y=1/2X-2
vagabundo [1.1K]
Point-slope form of a line: We need a point (x₀,y₀) and the slope "m";
y-y₀=m(x-x₀)

We have the next equation of line:
y=1/2 x-2  (slope-intercept form y=mx+b)

the slope of this line is 1/2  (m=1/2)
And any one point could be:
if x=0; then y=1/2 (0)-2=-2  (0,-2)

Therefore, we already have the point (0-,2) and the slope (m=1/2)
y-y₀=m(x-x₀)
y+2=1/2(x-0)

Answer: the point slope form of y=1/2 x-2; would be:
y+2=1/2(x-0)

Micah walks on a treadmill at 4 miles per hour. He has walked 2 miles
lana66690 [7]
<span>Let time taken by Luke to cover the distance = x hours Speed of Luke = 6 miles per hour Therefore, Distance covered by Luke = 6x ------(1) Speed of Micah = 4 miles per hour Since Micah walked 2 miles before Luke started running, Luke started 1/2 an hour after Micah started. Therefore time taken by Micah to cover the distance = x+1/2 Distance covered by Micah = 4(x + 1/2) -------(2) Equating (1) and (2) 6x = 4(x+1/2) 6x = 4x +2 2x = 2 x= 1 Therefore Luke would take 1 hour to cover the distance covered by Micah.</span>
