Answer:

y=2x

Step-by-step explanation:

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

Range⇒ 8

Mode⇒ 3

Step-by-step explanation:

Hope this helps

Answer:

mode is 2

Range is 6

Step-by-step explanation:

range is when you take the highest number which would be 8 and you minus by the lowest number which is 2 thus equals 6

Step-by-step explanation:

1. we can find the slope of the line using this formula:

\(\frac{y_2-y_1}{x_2-x_1}\)

y2, y1, x2, x1 are constants from the two coordinates given, so we just plug them into the formula

\(\frac{-13-19}{-1-3}\)

now we evaluate on both ends of the fraction

\(\frac{-32}{-4}\)

simplify

\(8\)

the slope is 8

2. we are given a graph which means we can simply count the slope

the slope means:

\(\frac{rise}{run}\)

which is the change in y over the change in x , this means that we can start at a coordinate and count the slope

using this method, we get a slope of 2

3. the slope is the change in y over the change in x. the y values are decreasing by -8 while the x values are increasing by ones

this means our slope is

\(\frac{-8}{1}=-8\)

4. we just have to use the aforementioned slope formula above

\(\frac{8-(-10)}{0-9}\)

evaluate

\(\frac{18}{-9}\)

simplify

\(-2\)

the slope is -2

Step-by-step explanation:

the answer is A) 63\(\frac{351}{441}\)

Answer:

63 Remainder 351

Step-by-step explanation:

For small division problems, the quotient and remainder can easily be thought of. But for larger division problems, long division is one technique that will work for any division problem, no matter how small or large it is.

Let's take a look at how long division works with the simple division problem of 7 / 3 first.

Setting up the problem, it looks like this with the 7 inside the division bracket and the 3 outside.

Answer:

-6 < 2

Step-by-step explanation:

as you can see on the number line -6 is farthest away from 0 and 2 is closest to 0 so there for 2 is greater than -6 plus any number that is a negative is always less than a positive number!

Answer:

a. 66c per oz of cheese bought

b. 66x

Step-by-step explanation:

a. Looking at the graph you can see that the price of 1 oz of cheese is 66 cents. As the graph is a straight line it is seen that the price rises by 66 cents per oz bought.

b. We use the answer of 66 cents per oz of cheese and change the cents out for x, to be able to a y = mx + b equation and since it starts at 0 the b = 0.

Answer:

7, 3, 7, 3

6, 4 6, 4

9, 1, 9, 1

Step-by-step explanation:

In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.

So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.

Since there are 18 numbers, I'm assuming we don't have to use all of them.

Answer:

The value of y is \(-1.33...\)

Step-by-step explanation:

WKT, the given equation is  \(\frac{-1}{2} =\frac{3}{8} y\)

Here, y is a variable.

Now, to solve the equation,

we need to multiply \(\frac{8}{3}\)  on both sides of the given equation, in order to get the values of y.

That is, \(\frac{-1}{2}\) × \(\frac{8}{3} =\frac{8}{3}\) × \(\frac{3}{8} y\)

⇒\(-\frac{1}{2}\) × \(\frac{8}{3}= y\)

⇒\(-\frac{8}{6}=y\)

⇒\(y=-\frac{4}{3}\)

or \(y=-1.333\)

Therefore, the value of y is \(-1.33...\).

Answer:

the 3 cm is the radius, if you multiply the radius by 2 you get the diameter, which is 6 cm in this case. If you use the formula for the circumference of a circle (diameter x pi = circumference) (circumference is distance around the circle) you get 6 x pi = 18.85 (note: 18.85 is not exact but rounded to 2 decimal points)

So the distance around the circle is 18.85 cm

Answer:

The fifth and sixth answer are solutions.

Step-by-step explanation:

If you substitute the x and y values, essentially multiplying them by the already existing coefficents, you realize that a lot of the equations do not equal 6.

The last two however, do.

The cost that will maximize the demand, considering the quadratic function, is given as follows:

$3.

The quadratic function representing the demand is given as follows:

y = -10x² + 60x + 180.

The vertex of a quadratic function is the point on the graph where the function reaches its maximum or minimum value. For a quadratic function in standard form y = ax² + bx + c, the x-coordinate of the vertex is given by:

x = -b / (2a)

The coefficients of the quadratic function in this problem are given as follows:

a = -10, b = 60.

The x-coordinate is the price that maximizes the demand, hence it is obtained as follows:

x = -60/(2 x (-20))

x = 3.

2. the slopes intercept is represented by b. the slope intercept is where you start on the y-axis of the graph.

3. the m in y=mx+b represents the slope which is followed by x so you can start graphing on the x-axis.

The level of accuracy of the measurement ruler measurement tool is 1/16 of an inch

Step-by-step explanation:

The accuracy of a measurement tool is determined by the ability of the tool measure the accurate value of the  actual or standard measurement. The accuracy of a measurement tool depends on its ability to take small measurements

The parameter given includes;

The number of divisions on each 1/2 inch of the ruler = 8

Therefore, the smallest divisions on the ruler = (1/2) inch ÷ 8 = 1/16 inch

Therefore, the level of accuracy of the measurement ruler measurement tool = 1/16 of an inch.
