Write the equation of a line perpendicular to y =
3
x-3 and whose y-intercept is (0,12).

Answer: $30 + $10h > $140.

Step-by-step explanation: Currently Cassie has $30, so that is the fixed amount of money she has. She needs $140 dollars, so this will be on the left side of your inequality with a "greater than symbol". Cassie can earn $10 an hour, use the variable "h" to represent the number of hours she will work. Set your inequality like this:

$30 + $10h > $140.

The reason why we use a "greater than" sign (>) is that the amount of money Cassie earns needs to be greater than the price of the calculator to be able to buy it.

Answer:

[tex]8x-5+2x\dfrac{x}{y}[/tex] = [tex]\dfrac{8xy-5y+2x^2}{y}[/tex]

Step-by-step explanation:

In this question, we need to simplify [tex]8x-5+2x\dfrac{x}{y}[/tex]

We can convert elements to fractions.

[tex]8x=\dfrac{8xy}{y},\:5=\dfrac{5y}{y}[/tex]

= [tex]\dfrac{8xy}{y}-\dfrac{5y}{y}+\dfrac{2x^2}{y}[/tex]

As the denominators are equal, we can combine the fractions as follows :

=[tex]\dfrac{8xy-5y+2x^2}{y}[/tex]

Hence, the simplified form is : [tex]8x-5+2x\dfrac{x}{y}[/tex] = [tex]\dfrac{8xy-5y+2x^2}{y}[/tex]

Answer:

  a) y = -7/640x^2 +7/4x

  b) y = -7/640(x -80)^2 +70

Step-by-step explanation:

a) Given the equation in standard form:

  y = ax^2 +bx +c

we can use the points (0, 0), (80, 70), and (160, 0) to find the values of a, b, c.

  a·0 +b·0 +c = 0

  a·80^2 +b·80 +c = 70

  a·160^2 +b·160 +c = 0

The first equation tells us that c=0, so we can write a reduced matrix for the last two equations. The augmented matrix is ...

  [tex]\left[\begin{array}{cc|c}6400&80&70\\25600&160&0\end{array}\right][/tex]

A matrix solver finds the solution to be ...

  a = -0.0109375 = 7/640, b = 1.75 = 7/4

The standard-form equation for Money's path is ...

  y = -7/640x^2 +7/4x

__

b) Factoring out -7/64, we have ...

  y = -7/640(x^2 -160x)

adding and subtracting the square of the x-coefficient, we have ...

  y = -7/640(x^2 -160x +6400) +70

  y = -7/640(x -80)^2 +70

the answer is B

Answer:

y = 1/4x + 0 or just y = 1/4x

Step-by-step explanation:

First I need the slope so I look at the dots and see how much boxes it goes up and then to the side. So it’s up 2 to the side 8. The slope would be 2/8 but you can simply it by 2 and you get 1/4. And the y intercept is given its zero.

Answer:

Adults living in San Francisco, California

Step-by-step explanation:

The population is the large group from which the sample is selected or chosen. In the question given the sample is drawn from the adult population of  San Francisco who are aged 40 to  50 to find out whether they can buy

an electric vehicle sometime in the next year.

The population it can be generalized to is adults living in San Francisco, California.

A population is defined as the group of all the individual members or objects having some common interest or characteristics.

The individual members are called the sampling units or simply units.

Answer:

adults only who live in San Francisco

Answer:

Two possible dimensions of the rectangle are 4x and 7/2 y.

Step-by-step explanation:

The Perimeter of a Rectangle

It's given the perimeter of a rectangle is

P = 8x + 7y

The formula to calculate the perimeter of a rectangle of dimensions L and W is:

P = 2W + 2L

Equating term by term, we can guess two possible dimensions of the rectangle:

2W = 8x

Dividing by 2:

W = 4x

And also:

2L = 7y

Dividing by 2:

L = 7/2 y

Thus, two possible dimensions of the rectangle are 4x and 7/2 y.

Answer:

She earned $360 on that paycheck.

Step-by-step explanation:

From the information given, you know that Angela transfers 15% of each paycheck and that she transferred $54 last week. With this, you can say that the amount she earned multiply for 15% is equal to 54, which you can express with the following equation:

0.15x=54, where x is the amount she earned on that paycheck.

Now, you can solve for x:

x=54/0.15

x=360

According to this, the answer is that she earned $360 on that paycheck.

Answer:

[tex]C = (\frac{11}{3},\frac{11}{3},\frac{7}{3})[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1,z_1) = (1,3,-2)[/tex]

[tex](x_2,y_2,z_2) = (4,5,0)[/tex]

[tex](x_3,y_3,z_3) = (6,3,9)[/tex]

Required

Determine the coordinates of the centroid

Represent the coordinates with C.

C is calculated as follows:

[tex]C = (\frac{1}{3}(x_1+x_2+x_3),\frac{1}{3}(y_1+y_2+y_3),\frac{1}{3}(z_1+z_2+z_3}))[/tex]

Substitute values of x and y in the given equation

[tex]C = (\frac{1}{3}(1+4+6),\frac{1}{3}(3+5+3),\frac{1}{3}(-2+0+9}))[/tex]

[tex]C = (\frac{1}{3}(11),\frac{1}{3}(11),\frac{1}{3}(7}))[/tex]

[tex]C = (\frac{11}{3},\frac{11}{3},\frac{7}{3})[/tex]

The above is the coordinate of the centroid

As we know that

So , we need to find side of square first

Using area of square = Side²

➩ 144 = S²

➩ S = √144

➩ Side = 12 cm

Now ,

➨ Diagonal = √2 ( 12 )

➨ Diagonal of square = 12√2
