Answer:

6(2-m)

Step-by-step explanation:

the m could not be times only two so the answer would have been 12-m no matter what you don't add or subtract or times the letter because unless if the number had the same letter

For the exponential equation <img src="https://tex.z-dn.net/?f=y%20%3D%203.4%280.66%29%5Ex" id="TexFormula1" title="y = 3.4(0.66

lisabon 2012 [21]

Answer:

Option: B is the correct answer.

B) Decay, y- intercept = 3.4, rate is 34%

Step-by-step explanation:

We are given an exponential equation as follows:

$y=3.4(0.66)^x$

We know that any exponential function of the type:

$y=ab^x$

is growth function if: b>1

and is a decay function if 0< b< 1

Hence, here we have: b=0.66<1

Hence, the function is a decay function.

Also, we know that the y-intercept of a function is the point where x=0

Hence, we take x=0

we have: $y=3.4\times (0.66)^0\\\\\\y=3.4$

Hence, the y-intercept is: 3.4

Also, the rate of a function is denoted by 'r'

where b=1-r

⇒ 0.66=1-r

⇒ r=1-0.66

⇒ r=0.34

Hence, the rate is: 34%

option: B is the correct answer.

Tomorrow Noelle wants to travel a total of 4 miles by walking and running she plans to run for 20 minutes at a rate of 6 miles p

elixir [45]

Answer:

Noelle will need to walk at a rate of 3 miles per hour for 2/3 of an hour to finish traveling the 4 miles.

Step-by-step explanation:

This will be a two part problem.

Noelle wants to travel 4 miles in total.

If she wants to run for 20 minutes at a rate of 6 miles/hour, we need to convert 20 minutes into terms of hours

20 minutes * 1 hour/60 minutes = 1/3 of an hour

let's find the distance she has traveled by running then using

d = r*t

where d is our distance in miles,

r is our speed in miles/hour, and

t is the time taken in hours

if r = 6 miles/hour and

t = 1/3 hours

we have

d = (6 miles/hour) * (1/3 hours)

hours will cancel out, leaving us with

d = 2 miles

If Noelle has covered 2 miles by running, how many minutes then will she need to walk at a rate of 3 miles per hour to cover the remaining two miles?

d = 2 miles

r = 3 miles/hour

2 miles = (3 miles/hour) *t divide both sides by 3 miles/hour

miles will cancel out, leaving us with

2/3 hours = t

Therefore, Noelle will need to walk at a rate of 3 miles per hour for 2/3 of an hour to finish traveling the 4 miles.

Solve the following system of equations. 2x+y=3 I= 2y - 1 x= y=

marin [14]

Note: I am assuming your second equation is:

x = 2y - 1

Answer:

The solution to the system of equations is:

x = 1

y = 1

Step-by-step explanation:

Given the system of equations

2x+y=3

x = 2y - 1

solving the system of equations using the elimination method

$\begin{bmatrix}2x+y=3\\ x=2y-1\end{bmatrix}$

Arrange equation variables for elimination

$\begin{bmatrix}2x+y=3\\ x-2y=-1\end{bmatrix}$

Multiply x-2y=-1 by2: 2x-4y=-2

$\begin{bmatrix}2x+y=3\\ 2x-4y=-2\end{bmatrix}$

subtracting the equations

$2x-4y=-2$

$-$

$\underline{2x+y=3}$

$-5y=-5$

now solve -5y = -5 for y

$-5y=-5$

Divide both sides by -5

$\frac{-5y}{-5}=\frac{-5}{-5}$

Simplify

$y=1$

For 2x+y=3 plug in y=1

$2x+1=3$

subtract 1 from both sides

$2x+1-1=3-1$

Simplify

$2x=2$

Divide both sides by 2

$\frac{2x}{2}=\frac{2}{2}$

Simplify

$x=1$

Therefore, the solution to the system of equations is:

x = 1

y = 1
