Answer:

x= 5.6

Step-by-step explanation:

we will need to put the information we currently have into an equation:

10•2•x= 112

then multiply 10•2 which equals 20...then the equation wil turn out like this:

20•x=112

now you will isolate the x... but how?? dividing 20 by itslef.. cancelling it out, and if you do one thing to the other side of the equation, you have to do it to the other...

20/20•x=112/20

you will end up with x= 122/20

you can use a calculator for this step, but to practice long division... (check the screen shot thingie)

hope this helped !! ^^

Graph the system of equation below on a piece of paper what is the solution y=x-1 and y=-2x+5

ANTONII [103]

We are given

First equation:

$y=x-1$

we can use formula

$y=mx+b$

slope is m=1

y-intercept is b=-1

Second equation:

$y=-2x+5$

we can use formula

$y=mx+b$

slope is m=-2

y-intercept is b=5

Graph:

We can see that

both curves intersect at (2,1)

so, solution is x=2 and y=1.................Answer

What is the total amount for an investment of $1600 invested at 4.25% for 20 years and compounded continuously?

galina1969 [7]

Answer:

$3743.43

Step-by-step explanation:

The amount is given by the formula ...

A = Pe^(rt)

where P is the principal, r is the annual rate compounded continuously, and t is the number of years. Filling in the values, we get ...

A = $1600·e^(0.0425·20) = $1600·e^0.85

≈ $1600·2.33964685 ≈ $3743.43

The amount in the account will be $3743.43.

answer:

2y(x³+4x-2x²-8)

Part B: Factor the entire expression completely. Show the steps of your work. (6 points)

answer:

2y(x³+4x-2x²-8)

2y(x³-2x²+4x-8)

2y(x²(x-2)+4(x-2))

2y(x²+4)(x-2)
