The answer is C
x= months
y=$
Constant of proportionality (C)=y/x
x=1, y=3.5
3.5/1=3.5
x=2, y=7
7/2=3.5
x=3, y=10.5
10.5/3=3.5
x=4, y=14
14/3=3.5
x=5, y=17.5
17.5/5=3.5
C=3.5

Solve for x 9(x+1)=25+x X=2 X=3 X=4 X=5

scoray [572]

Answer:

X=2

Step-by-step explanation:

9(x+1)=25+x

Step 1: Simplify both sides of the equation.

9(x+1)=25+x

(9)(x)+(9)(1)=25+x(Distribute)

9x+9=25+x

9x+9=x+25

Step 2: Subtract x from both sides.

9x+9−x=x+25−x

8x+9=25

Step 3: Subtract 9 from both sides.

8x+9−9=25−9

8x=16

Step 4: Divide both sides by 8.

8x/8=16/8

X=2

I’m pretty sure it’s the victim did not have a venomous bite, move the a^-4 up and the b^-4 down so the expression would be a^5a^4/b^4b^3, you would multiply them which makes you add the exponents which would make it a^9/b^7. Hope this helps :)

A mobile base station (BS) in an urban environment has a power measurement of 8µW at 225m. Assuming the propagation follows an i

nata0808 [166]

Answer:

The reasonable value = 2.96 × 10^(-1) µW

Step-by-step explanation:

* Lets explain how to solve the problem

- A mobile base station in an urban environment has a power

measurement of 8 µW at 225 m

- The propagation follows an inverse cube power law

- We need to find the reasonable value to assume at a distance

678 m from the base station

∵ The propagation follows an inverse cube power law

- The power would have been decreased by a factor 1/n³

times the power as a distance increasing

∵ n = the ratio between the distances

∵ The distance are 675 m and 225

∴ n = 675/225 = 3

∴ 1/n³ = 1/3³ = 1/27

- The reasonable value is the product of the power measurement of

8 µW and 1/27

∴ The reasonable value = 8 × 1/27 = 8/27 µW = 0.296296

∴ The reasonable value = 2.96 × 10^(-1) µW

(3v^4 - 2) - (7v^4 + 6)

Lera25 [3.4K]

So firstly, you want to foil - (7v^4 + 6) [Think of the minus sign as -1]: $3v^4 - 2 - 7v^4 - 6$

Next, combine like terms and your answer will be: $-4v^4-8$
