Multiply the cost, 120, by 0.07
you will get 8.4

Janet will pay $8.40 in sales tax

Solve the equation ?

Morgarella [4.7K]

6m+1=-23. Do the inverse operation of adding 1 which is to subtract 1 to both sides =====> 6m+1-1= -23-1

You divide by 6 both sides
6m/6=-24/6

m= -4

Write the equation in slope intercept form 2x+y=6

Rina8888 [55]

Answer: the slope intercept form of 2x+y=6 is y=-2+6

Step-by-step explanation:

2x+y=6 (subtract 2x from both sides)

-2x -2x (the -2x and the 2x cancel leaving...)

y=-2x+6 →( y equals negative two x plus six)

Is 4/7 24/35 perform a ratio

uysha [10]

No. If 4x= 24 then x=6. 7 multiplied by 6 equals 42, not 35 so this is not a ratio.

nydimaria [60]

Answer:

$2.58\ more\ nuts\ Miguel\ uses\ than\ raisins.$

Step-by-step explanation:

$Nuts\ used=5\frac{1}{3}\\\\Nuts\ used=\frac{16}{3}$

$Raisins\ used=2\frac{3}{4}\\\\Raisins\ used=\frac{11}{4}$

$difference\ between\ nuts\ and\ raisin=\frac{16}{3}-\frac{11}{4}=\frac{64-33}{12}=\frac{31}{12}\approx 2.58$

$2.58\ more\ nuts\ Miguel\ uses\ than\ raisins.$

A firm has a revenue function that can be represented by r (x)=700x-0.35x^2, where r (x) is the total revenue (in dollars) and x

Fudgin [204]

Answer:

How many units need to be sold to produce the maximum revenue? 1000 units

How many in dollars is the maximum revenue when the maximum of units are sold? $350,000

Step-by-step explanation:

We get max value of a function if we differentiate it and set it equal to 0.

We need to differentiate r(x) and set it equal to 0 and solve for x.

That would be number of units sold to get max revenue.

Then we take that "x" value and substitute into r(x) to get the max revenue amount.

Before differentiating, we see the rules shown below:

$f(x)=ax^n\\f'(x)=n*ax^{n-1}$

Where

f'(x) is the differentiated function

Now, let's do the process:

$r (x)=700x-0.35x^2\\r(x)=700-2*0.35x\\r(x)=700-0.7x\\0=700-0.7x\\0.7x=700\\x=1000$

So, 1000 units need to be sold for max revenue

Now, substituting, we get:

$r (x)=700x-0.35x^2\\r(1000)=700(1000)-0.35(1000)^2\\r(1000)=350,000$

The max revenue amount is $350,000
