Answer: y = -2x + 14

Step-by-step explanation:

original slope: 1/2

new slope : -2

y=mx+ b

y= -2x+b

6= -2(4) +b

6 = -8 + b

14 = b

y = mx + b

y = -2x + 14

Find f (2b^2) for (x)=x^2-4x

BlackZzzverrR [31]

Answer:

Step-by-step explanation:

We are given the function:

$f(x) = x^2 - 4x$

And we want to find:

$\displaystyle f(2b^2)$

Substitute:

$\displaystyle f(2b^2) =(2b^2)^2 -4(2b^2)$

And evaluate:

$\displaystyle \begin{aligned} f(2b^2) &=(2b^2)^2 -4(2b^2) \\ &=(4b^4) +(-8b^2) \\ &= 4b^4 - 8b^2 \end{aligned}$

In conclusion, our answer is A.

the utility bill for the Millers home was it in April with $132 42% of the bill was for gas and the rest for electricity how muc

Anit [1.1K]

In the given question, there are several data of immense importance. based on these data's the answer to the question can be easily deduced. it is already given that the total utility bill for the month of April in Millers house is $132 and 42% of the bill was paid for gas. remaining amount is paid as electricity charges.
Now
Amount of money paid for gas = 132 * (42/100) dollars
      = 5544/100 dollars
   = 55.44 dollars
Then
The amount of money paid for electricity = (132 - 55.44) dollars
   = 76.56 dollars
So the Millers paid 55.44 dollars for gas and 76.56 dollars for electricity in the month of April.

Answer:

Step-by-step explanation:

You can eliminate answer A because when X=1, Y must equal 33.75 not 33.

You can eliminate answer B because when X=0, Y must equal 0 not 1.

You can eliminate answer D because this answer has the X and Y coordinates reversed. When X=1, Y= 33.75. When X=4, Y=135, etc.
