What is the solution to the equation? (-9x+5)^1/2=(3+4x)1/2

Phoenix [80]

<span>x in (-oo:+oo)

((5-9*x)^1)/2 = ((4*x+3)^1)/2 // - ((4*x+3)^1)/2

((5-9*x)^1)/2-(((4*x+3)^1)/2) = 0

(5-9*x)/2-((4*x+3)/2) = 0

(5-9*x)/2+(-1*(4*x+3))/2 = 0

5-1*(4*x+3)-9*x = 0

2-13*x = 0

(2-13*x)/2 = 0

(2-13*x)/2 = 0 // * 2

2-13*x = 0

2-13*x = 0 // - 2

-13*x = -2 // : -13

x = -2/(-13)

x = 2/13

x = 2/13</span>

WILL MARK BRAINLIEST FOR BEST ANSWERA

Fantom [35]

Answer:

The length of the road that runs straight from Pittsburgh to Jeanette is 29.8 miles

Step-by-step explanation:

We are given

Bethel Park is 28 miles directly west of Jeanette

10.3 miles directly south of Pittsburgh

We can draw diagram

we can see that this is triangle

so, we can use Pythagoras theorem

and we get

$x^2=28^2+10.3^2$

now, we can solve for x

$x=\sqrt{28^2+10.3^2}$

$x=29.834miles$

So,

The length of the road that runs straight from Pittsburgh to Jeanette is 29.8 miles

Help with this math

yan [13]

13. Four observations:

1. m<SWT = 90° (given)

2. QW = TW (given)

3. m<RWS = m<UWV (vertical angle pair)

4. m<RWU = 180° (straight angle)

Hey can anyone please help with this

g100num [7]

Step-by-step explanation:

Among these three options , Option B is the correct answer.

GF||JK

So,m<F= m<K. ( alternate interior angles)

and , m<G= m<J. (alternate interior angles)

so ∆FGH similar to∆KJH
