Distribute the 3(6-4x) to get 18-12x-27x+10x-31. then simply combine like terms (coefficients same variable, in this case X) to get -29x-13

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.

The function ƒ(x) = (x − 1)^2 + 5 is not one-to-one. Find a portion of the domain where the function is one-to-one and find an i
melisa1 [442]

Answer:

f(x)=(x-1)^2+5 with domain x>1 and range y>5 has inverse g(x)=sqrt(x-5)+1 with domain x>5 and range y>1.

Step-by-step explanation:

The function is a parabola when graphed. It is in vertex form f(x)=a(x-h)^2+k where (h,k) is vertex and a tells us if it's reflected or not or if it's stretched. The thing we need to notice is the vertex because if we cut the graph with a vertical line here the curve will be one to one. So the vertex is (1,5). Let's restrict the domain so x >1.

* if x>1, then x-1>0.

* Also since the parabola opens up, then y>5.

So let's solve y=(x-1)^2+5 for x.

Subtract 5 on both sides:

y-5=(x-1)^2

Take square root of both sides:

Plus/minus sqrt(y-5)=x-1

We want x-1>0:

Sqrt(y-5)=x-1

Add 1 on both sides:

Sqrt(y-5)+1=x

Swap x and y:

Sqrt(x-5)+1=y

x>5

y>1

Which statement is true about the line represented on the equation y + 7 = -3 (x - 2/9) ?
Zarrin [17]

<u>ANSWER</u>

The point (\frac{2}{9},-7) lies on the straight line y+7=-3(x-\frac{2}{9})

<u>EXPLANATION</u>

The given line is y+7=-3(x-\frac{2}{9}). It can be observed that the given straight line is in the point-slope form.

We can rewrite the equation in the point-slope form to obtain,


y--7=-3(x-\frac{2}{9}).


When we compare this to the general point-slope form, which given by the formula;

y-y_1=m(x-x_1),

We can observe that,

x_1=\frac{2}{9} and y_1=-7.


Hence the point, (x_1,y_1)=(\frac{2}{9},-7) lies on y+7=-3(x-\frac{2}{9})
