Solve for k.20 - 6+ 4k = 2 - 2k​

Mathematics
1 answer:
Mumz [18]3 years ago
7 0

Answer:

K= -2

Step-by-step explanation:

20-6+4*k-(2-2*k)=0

Pull out like factors

12 + 6k  =   6 • (k + 2)

Solve: 6 = 0 which ends that this equation has no solution because a non zero constant never equals zero

Solve: K+2 = 0

now substract 2 from both sides of the equation: K= -2

Hope I explained myself :/

Hope it helps :)

Here are the step for solving this:
1. 3y + 5 > 23
-5 -5
3y/3 > 18/3
y > 6

In words what you are doing is getting y by itself on one side. Subtract the 5 to undo the adding of 5 first. Then, divide both sides by 3.

The variable x varies directly as the cube of y, and y varies directly as the square root of z. If x equals 1 when z equals 4, w
Aloiza [94]

Answer:

<h2>z=36</h2>

Step-by-step explanation:

According to the question,

x∝y^3          .......(1)

y∝\sqrt{z}    .......(2)

From equation 1,2 let constant of proportionality be k1,k2 respectively.

⇒x=k1(y^3)            .......(3)

⇒y=k2(\sqrt{z} )    .......(4)

From the above equations putting 4 into 3,

x=k1((k2\sqrt{z})^3) =k1.k2^3.(\sqrt{z})^3

Let the new constant to the above equation be k3,

x=k3(\sqrt{z})^3

Given,if x=1, when z=4

1=k3(\sqrt{4} )^3=k3(8)

⇒k3=\frac{1}{8}

Now if x=27, then z=?

27=\frac{1}{8} (\sqrt{z} )^3

⇒(\sqrt{z} )^3=27(8)

⇒\sqrt{z}=3(2)=6

z=36
