Given:

The equation is

$30+7y=-2y-6$

To find:

The solution for the given equation.

Solution:

We have,

$30+7y=-2y-6$

Isolate the variable terms on the left side, we get

$7y+2y=-30-6$

$9y=-36$

$y=\dfrac{-36}{9}$

$y=-4$

Therefore, the value of y is -4.

Answer:

See below description.

Step-by-step explanation:

The function $f(x) = x^4+x^3-2x^2$ has the following characteristics:

Factors: $x^2(x+2)(x-1)$
Zeros/roots: x=0, x=-2, amd x=1
Positive leading coefficient
Graph starts up, curves down through -2 on the x-axis and back up to 0 where it touches and curves down and back up again again. It comes down back through 1 and crosses.
Its graph s the shape of a W.
It has minimum values at -2.83 and -0.397

Answer:

The amount of acid in third container is =42%

Step-by-step explanation:

Given , one container is filled with a mixture that is 30% acid a second container filled with a mixture that is 50% acid and the second container 50% larger than the first .

Let, the volume of first container is = x

Then , the volume of second container = (x+ x of 50%)

= x + 0.5 x

= 1.5 x

Therefore the amount of acid in first container $=x \times \frac{30}{100}$ = 0.3 x

The amount of acid in second container $=1.5x \times \frac{50}{100}$ = 0.75x

Total amount of acid= 0.3x + 0.75x = 1.05 x

Total amount of solution = x+1.5x = 2.5x

The amount of acid in third container is = $\frac{1.05x}{2.5x} \times 100%$ %

= 42%

Answer:

The average rate of change from 3 to 6 storms = 0.04

Step-by-step explanation:

Let number of Storms = N

And Predicted Gas Price = P

it is required to find the average rate of change from 3 to 6 storms.

At N = 3 ⇒ P = $2.44

At N = 6 ⇒ P = $2.56

So, the average rate of change = $\frac{2.56-2.44}{6-3}=\frac{0.12}{3}=0.04$
