If 3x^2+4x/2x+9=5 find x

Mathematics

Simora [160]3 years ago

° ∪ ° Hi there!

Let's solve your equation step-by-step.

3  x^{2} +   \frac{4x}{2} x + 9 = 5

Step 1) Simplify both sides of the equation.

5 x^{2} + 9 = 5

Step 2) Subtract 9 from both sides.

5 x^{2}  + 9 - 9 = 5 - 9

5 x^{2} = -4

Step 3) Divide both sides by 5.

\frac{5x^2}{5} =  \frac{-4}{5}

x^{2} =  \frac{-4}{5}

Step 4) Take the square root.

(This isn't something I can write the whole thing with the pretty writing.)

x = ± \sqrt  \frac{-4}{5}

Answer -

There are no real solutions.

We, unfortunately, do not have an x since there are no real solutions.

Hope this helps! :D

Ip a solid sphere with a diameter of 0.19 m is released from rest; it then rolls without slipping down a ramp, dropping through
lubasha [3.4K]
<span>Answer: K = (1/2) mv² + (1/2) Iω², where m is the ball mass, I is the ball's moment of inertia (2/5)mr², and ω is the angular velocity of the ball. Because the ball rolls without slipping, it is easy to see that v=ωr, or r=v/ω. Then, K = (1/2)mv² + (1/2)(2/5)mr²ω² = (1/2)mv² + (1/5)mv² = (7/10)mv² Setting potential at the top equal to kinetic at the bottom, mgh=(7/10)mv² v=âš{(10/7)(gh)} = [(10/7)(9.8)(0.51)]^(1/2) = 2.672m/s</span>

Polly bought a cracker for $7 and then bought a parrot for $2. By how much did Polly's account change after her transactions?
marysya [2.9K]

Answer:

Changes = -\$9

Step-by-step explanation:

Given

Cracker = \$7

Parrot = \$2

Required

Determine the changes in the account

First, we need to determine the total amount spent;

Total = Cracker + Parrot

Total = \$7 + \$2

Total = \$9

<em>Hence, the changes in her account is a debit of $9 i.e. -$9</em>

What restrictions are there on the range of the function H(w) below?
Eddi Din [679]
The function, named H(w) is defined by a graph that is a descendant line, that belongs only to the first quadrant. As w approaches to 0 by the right, the function approaches to + infinity. It never touches the vetical axis, decreases and approaches to 0 when w approaches to infinity. The graph never touches the horizontal - axis.

Then, the function is defined only for positive values of w and H(w) is always positive.

Then, the answer is H(w) > 0, this is the option C.
