Hi there! Hopefully this helps!

------------------------------------------------------------------------------------------

<h2>Answer: x = 12.</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2><h2 />

9x = 108

Divide both sides by 9.

\frac{108}{9}

<h2>Divide 108 by 9 to get, you guessed it, 12!</h2>

The length of one leg of a right triangle is 24 feet and the length of the hypotenuse is 40 ft what is the length of the other l
Rama09 [41]
To solve for the other leg, you need to use Pythagorean theory.

The theory states that C^2 = A^2 + B^2

In your case, you have to solve for B.
C = 40 (hypotenuse)   A = 24 (leg 1)

The formula rewritten for B is b= \sqrt{c^{2}-a^{2} }

Now, you can solve.

b= \sqrt{c^{2}-a^{2} }&#10;&#10;b= \sqrt{40^{2}-24^2 }&#10;&#10;b = \sqrt{1600 - 576}&#10;&#10;b = \sqrt{1024}&#10;&#10;b = 32

Therefore, B = 32.

So the second leg is 32 feet.

X-4=10;4x+1=57<br>i need to change the first equation into to the second equation.
cestrela7 [59]

Is this what you mean this is what i understood.



X-4=10;4x+1=57


First equation solve for x.

X-4=10

Add 4 both sides

X=10+4


X=14

Second equation substitute your x answer into second equation to make both sides equal.

4x+1=57

4(14)+1=57

56+1=57

57=57

I need help with 7-14
aliina [53]
7: $200<3x-y(28) where x represents each kids money out of it and y represents the parents pay.
8: 7.00>(is greater then or equal to) 0.75X + 1.29Y where X is the amount of bagels and Y is the amount of cream cheese containers.
9: $25 + $75>4X where X is the shirts
10: 720-120>(greater then or equal to) 32X where X is the number of people in each row
11: 2400= 2100+ X(1/20) where X is the value of all things sold.
12: 2000<(X7)-668 where X is the amount of cans in one day.
13: 100> 7X - 10Y where X equals the amount of months and Y equals the amount of CD's
14: $80 - $22> (greater than or equal to) 17X where x equals the amount of shirts.

first off sorry it took so long to answer, these long word questions are time consuming and i havent done them in a while so i had to refresh my memory, secondly the equations all end where i say the word "where", thirdly i am absolutely sure of all these answers except for the first one, the first one i am pretty sure i still got it but not 100%.

hope this helps.

I need help. Basically, I need to figure out the dependent and independent value of a function.
Rama09 [41]

Answer:

  • x = log(y/4)/log(1.0256)
  • your answer for y=12 is correct

Step-by-step explanation:

The question is asking you to solve ...

   y = f(x)

for x. (In other words, find the inverse function.)

You already did this using a constant for y. Do the same thing with y instead of the constant.

  y = 4(1.0256^x)

  y/4 = 1.0256^x . . . . . . . divide by 4

  log(y/4) = x·log(1.0256) . . . . . take logs

  log(y/4)/log(1.0256) = x . . . . . divide by the coefficient of x

Now, you have a model for x in terms of y, which is what the question is asking for.

  x = log(y/4)/log(1.0256) . . . . . . . exact expression

When y=12, this is ...

  x = log(12/4)/log(1.0256) ≈ 43.46 . . . . weeks

_____

This is a linear equation in log(y), so can be written as such:

  x = 91.0912·log(y) -54.8424 . . . . . approximate expression
