Answer: x=6 y=3 z=2

Step-by-step explanation: The question is very vast so im guessing that its just finding 3 whole numbers that can equal the same ammount being multipied by 2 and 3. I chose 6. But theres many others. The answer should be correct because if we replace the letters with the numbers i put in the answer it should look like this: 6=2•3=3•2

When we do simplify this we should get 6=6=6 which is true.

Again you can use different numbers for example 12 as X. Then you need to divide 12 by whats behind the Y. So 12÷2 is 6. So Y is equal to 6. To find Z all you need to do is follow the same steps as Y. Find the number behind Z (3) and divide that into 12. So it would be 12÷3. And if you do the math right it should look like this: X=12, Y=6, Z= 4. And when you imput the numbers to thier corresponding letter it should look like this 12=2(6)=3(4) which simplified looks like 12=12=12 which is true.

Answer:

You would use the formula: Rate = distance / time which equals 55

Since we are asked for the time it takes to reach 3/4 the destination.We just use 3/4 of the value of the distance.

55 = (3/4)(440) / t

t = 6 hours

So the answer would be "C"

Answer:

The yearly rate of appreciation of the comic book is r=0.017 or r=1.7%

Step-by-step explanation:

we have

$v(t)=1,350(1.017)^{x}$

This is a exponential function of the form

$f(x)=a(b)^{x}$

where

a is the initial value

b is the base

In this problem

a=$1,350

b=1.017

Remember that

b=1+r

1+r=1.017

r=1.017-1=0.017

therefore

The yearly rate of appreciation of the comic book is r=0.017 or r=1.7%

Can anybody please help me??

Answer:

(x, y) = (6, 1) is the solution

Step-by-step explanation:

Each of the equations is written in "slope-intercept" form:

y = mx + b . . . . . . . . where m is the slope and b is the y-intercept

<u>First equation</u>

The y-intercept is +7 and the slope is -1. That means the line goes down 1 unit for each unit it goes to the right. It will go through the points (0, 7) and (7, 0).

<u>Second equation</u>

The y-intercept is -2 and the slope is 1/2. That means the line goes up 1 unit for each 2 units it goes to the right. It will go through the points (0, -2) and (4, 0).

The lines will intersect at the point (6, 1), which is the solution found by graphing.
