What steps do I do to answer this

Gnesinka [82]

Your equation is: 5h + 4 = 10h + 8

First subtract 5h from both sides:(So that variable terms stays in one side only)

=> 5h + 4 -5h = 10h + 8 -5h

=> 4 = 5h + 8

Now subtract 8 from both sides:(So constant term stays in the opposite side of variable terms)

=> 4 - 8 = 5h + 8 - 8

=> -4 = 5h

Now divide both sides by 5:(division by coefficient of variable)

=> -4/5 = 5h/5

=> -4/5 = h

=> h = -4/5 = -0.8

If you are given the functions f(x) = 3x + 1... Can you find the input value if f(x) = 10

VARVARA [1.3K]

Answer:

Input value: 3

Step-by-step explanation:

If I'm understanding the question correctly it would look like this.

$10 = 3x + 1$

Next: Subtract one

$9 = 3x$

Divide by three to get x.

The length of a rectangle is

UkoKoshka [18]

Answer:

5 meters

Step-by-step explanation:

We should derive an equation to solve this problem.

Let's assign x to width and y to length.

$2x-4=y$

and

$2x+2y=22$

$2x+2(2x-4)=22$

$2x+4x-8=22$

$6x-8=22$

$6x=30$

$x=5$

Width = 5 meters

You save for retirement over 30 years by investing $850/month in a stock account that yields 10%. You invest $350/month in a bon

sergejj [24]

Answer:

$13,287.70

Step-by-step explanation:

The future value of the stock account is computed as the sum of a geometric series. This computation assumes that the annual yield is compounded monthly.

FV = p((1+r/12)^(12n) -1)/(r/12)

For the stock account, p=850, r=0.10, n=30, so the future values is ...

FV = 850((1+.10/12)^360-1)/(.10/12)) = 1,921,414.74

For the bond account, p=350, r=.06, n=30, so the future value is ...

FV = 350((1+.06/12)^360 -1)/(.06/12) = 351,580.26

The combined account value at the end of 30 years is ...

$1,921,414.74 + 351,580.26 = $2,272,995.00

_____

The monthly payment that can be made over a 25 year period is given by the amortization formula.

A = P(r/12)/(1 -(1 +r/12)^(-12n))

= $2,272,995.00(.05/12)/(1 -(1+.05/12)^-300) = $13,287.70

You can withdraw $13,287.70 each month assuming a 25-year withdrawal period.
