Answer:

The discriminant of the quadratic equation is 0

Step-by-step explanation:

Here, we want to calculate the discriminant of the given quadratic equation

Mathematically, we have the discriminant calculated by the following formula;

D = b^2 - 4ac

where;

b represents the coefficient of x which is -2

a is the coefficient of x^2 which is 1/7

c is the last number which is 7

Substituting these values;

D = (-2)^2 -4(1/7)(7)

D = 4 - 4

D = 0

Step-by-step explanation:

The line is in between 106° and 108° so it is 107°

Answer:

We want to find the solution region for:

y < -2*x + 1

To find the region, the steps are:

Write the inequality as an equation like:

y = -2*x + 1

Let's graph this line.

Because we have the symbol "<", the line will be a dashed line. This is because y is strictly smaller than the line, so the points of the line itself are not solutions.

And our inequality is:

y < -2*x + 1

So y is smaller than the line, then the shaded region is all the region below the line.

The graph of this inequality is shown below.

Answer:

0 Blankets

Step-by-step explanation:

2.5 yards is 7.5ft, and Molly only has 2.5ft, so she can not make a blanket.

The question is incomplete. The complete question is :

Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower and gas, and his revenue is $25 per lawn. At what point will Nate's revenue exceed his expense?

Cost of lawn mower = $ 200

Cost of gasoline = $ 2 per lawn

Solution :

Given :

Cost of the lawn mower = $ 200

The cost of gasoline expense for one lawn = $ 2

The revenue generated for one lawn = $ 25

So let the number of lawn to be mowed = x

Therefore the total expenses = [tex]$200+2x$[/tex]

So, the total revenue = [tex]$25x$[/tex]

The point for which the revenue will exceed the total expenditure will be :

[tex]$25x \geq 200+2x$[/tex]

So at [tex]x=9, \ 225 > 218[/tex]

Thus the revenue exceeds the total expenditure after mowing 9 number of lawns.

Answer:

For part a and b of this question

Step-by-step explanation:

x= # of lawns cut      y= total cost

revenue: y=25x

cost: y= -2x-200

He earns 25 per lawn, but loses $200 for his lawnmower and $2 per lawn.

b.  y=25x            y=-2x-200                    y=25x              

    y=-2x-200     25x=-2x-200                y=25(-7.40)

                              27x= -200                 y=-185

                                   x=-7.40

I believe this is correct.

Step-by-step explanation:

its not c or b, they are both negative, and D is y=x, so A = y=2x because 2/1 is 2, the gradient

Step-by-step explanation:

To multiply out brackets, you multiply the values within the bracket by the one outside one at a time.

For example, for the first one, you would do 2*a, which is 2a, then 2*3, which is 6. Since the 3 was positive, the answer would be 2a+6.

Answer:

x= -9/4

Step-by-step explanation:

1) Isolate X

2) This will give you x+15x+4x=-21-24

(moving terms to another side will make it opposite, in this case positive 24 moving to the right will become negative 24)

3) Add the like terms

x+15x+4x = 20x

-21-24= -45

this will give you 20x=-45

4)Find the value of X by moving the 20 multiplier to the other side (this will become the opposite, division of 20)

x= -45/20

5) Simplify your answer

= -9/4

Answer:

the answer to the problem is 875,100

Answer:

Step-by-step explanation:

When we round to a particular place, we will use a few simple rules.

First, let's highlight the place value we're rounding to.

875,098

Next, we look at the number behind the highlighted number, in this case the tens place. If the number is less than 5, the highlighted place value will stay the same. If the number is 5 or above, the highlighted place value increases by 1. In this case, we round 0 up to 1, since there was a 9 in the tens place. We then add zeros for the tens and ones place, since we rounded out of those.
