Answer:

d

Step-by-step explanation:

Given

3x - x + 2 = 12, that is

2x + 2 = 12 ( subtract 2 from both sides )

2x = 10 ( divide both sides by 2 )

x = 5

Solve the equation or formula for the indicated variable a=4b^5h
melisa1 [442]
Given that the formula we are required to solve for h:
a=4b^5h
to solve for h we divide both sides by 4, this will give us:
a/4=(4b^5h)/4
a/4=b^5h
next we divide both sides by b^5, this will give us:
a/(4×b^5)=(b^5h)/b^5
a/(4b^5)=h
hence the answer is:
h=a/(4b^5)

What is the parent function for the following<br><br> f(x) = (x-2) (x-1)
Taya2010 [7]

Answer:

The parent function of  f(x) = (x-2) (x-1) is  P(x) = x^2- 3 x + 2.

Step-by-step explanation:

Here, f(x) = (x-2) (x-1)

Now, parent function of a given function is the function, which is PRODUCT OF ALL IT S FACTORS.

Now, here, f(x) has two factors ( x- 2) and ( x-1)

So, the parent function p(x) of f(x) is given as the product of both the factors.

So, we get:

P(x)  = (x-2) (x-1) \\=  x( x-1) -2(x-1)\\=x^2 - x -2x + 2\\= x^2- 3 x + 2\\\implies P(x) = x^2- 3 x + 2

Hence, here the parent function of  f(x) = (x-2) (x-1) is  P(x) = x^2- 3 x + 2.

The percent increase from 8 to 14 equal to the percent decrease from 35 to x. what is the value of x
zhenek [66]

Answer:

x= 20 and the decreased value is 35-20=15

Step-by-step explanation:

percent increase = 6/14*100= 43

Percent decrease = 35-x/35*100

6/14*100=35-x/35*100

6/14= 35-x/35

6* 35= 14(35-x)

210= 490-14x

14x= 490-210

14x= 280

x= 280/14= 20
