Answer:

y = -2x + 1

Step-by-step explanation:

First we're going to find the gradient (the number in the green box with the question mark).

We use the formula [tex]\frac{y2-y1}{x2-x1}[/tex] to calculate the gradient.

Let's make (-1, 3) be our (x1, y1), and (2, -3) be our (x2, y2).

Substitute the points into our formula:

gradient = [tex]\frac{(-3)-3}{2- (-1)}[/tex]

gradient = [tex]\frac{-6}{3}[/tex]

gradient = -2

Next, we're going to find the y-intercept (the number in the grey box)

Now that we have the gradient, our equation looks like this:

y = -2x + c

We use the letter c to represent the y-intercept of a linear graph.

Substitute one of the points given into the x and y in the equation. Let's use (-1, 3).

3 = -2(-1) + c

3 = 2 + c

c = 1

So our equation is y = -2x + 1

Answer:

a linear function with slope 3 and y intercept -6

Step-by-step explanation:

f(x) = 3x - 6 is definitely a linear function with slope 3 and y intercept -6.

Next time please be sure to share the answer choices.  Thanks.

Given function of [tex]f(x)= 3x-6[/tex] represents a linear function representing straight line with no maximum and no minimum. Slope of the given line [tex]= 3[/tex] and y - intercept [tex]= -6.[/tex]

" Linear function is defined as the relation between variables with highest exponent equals to one".

According to the question,

Given

Function[tex]f(x)= 3x-6[/tex]

[tex]f(x)= 3x-6[/tex] is function in one variable x with highest exponent 1.

Therefore, it is a linear function.

Represents the straight line.

x increases y also increases.

No maximum and minimum point.

Compare it with general equation of line [tex]y = mx + c[/tex]

Slope of the line [tex]= 3[/tex]

Y- intercept [tex]= -6[/tex]

Hence,  function of [tex]f(x) = 3x-6[/tex] represents a linear function representing straight line with no maximum and no minimum. Slope of the given line [tex]= 3[/tex] and y - intercept [tex]= -6.[/tex]

Answer:

the table that has the same additive rate of change. so you subtract the last number to the one before it.  to get the rate of change but you need to the same with every number in the y values.

Step-by-step explanation:

for example if the table has 1,2,3,4 point with the y values with 2, 4, 6,8. so you will get 8-6=2 then you repeat: 6-4=2, 4-2=2. when they are the same meaning its a linear function.

Answer:

The x-intercept is (-9,0). The y-intercept is (0,27).

Step-by-step explanation:

9x - 3y = -81

-9x         -9x                  Subtract 9x from both sides

-3y = -9x - 81                Divide both sides by -3

y = 3x + 27

I graphed the equation below.

Step-by-step explanation:

9x-0=-81

divide all through with 9x to get

x=-2

0-3y=-81

divide all through with 3y to get

y=27

Answer:

3/35

Step-by-step explanation:

Here, we want to know the constant of proportionality in this direct variation scenario

Since it is a direct variation, the form we are having would be;

x = ky

where x and y directly vary with each other and k is the constant of proportionality

Now, for the first relation

3 = 35k

for the second

9 = 105k

Thus k would be

3/35 which is the same as 9/105

Kindly note that 9/105 can be reduced to 3/35

So linking the number of weeks to the number of stamps collected, the constant of proportionality is 3/35

The answer is A.) y =35/3x

Answer:

A. 101 × q / 2000 S

B. Ingresos totales de q unidades = 230 · q - q²

Costo total para producir q unidades = 101 × q / 2000 S

C. 222 carteras

Step-by-step explanation:

A. Ingresos totales = q × (230 - q) = 230 · q - q²

El costo unitario = S / 20

El costo fijo = S / 2000

Costo total para producir q unidades = q × (S / 20 + S / 2000) = 101 × q / 2000 S

B. Las ganancias totales = Ingresos totales- Costo total

Las ganancias totales = 230 · q - q² - 101 · q / 2000

Las ganancias totales = 229.9495 · q - q²

C, cuando las ganancias obtenidas = 1800 soles, tenemos;

1800 = 229.9495 · q - q²

q² -229.9495 + 1800 = 0

(q - 8.114) × (q - 221.84) = 0

Por lo tanto, q = 8.114 o q = 221.84

Por lo tanto, sabemos que q> 50, por lo tanto, el valor correcto de q = 221.84 o 222 carteras.

Answer:

Answer:

Option B is correct

Step-by-step explanation:

Given: [tex]\left | p \right |=7\sqrt{2}\,,\,\left | p+q \right |=12\sqrt{3}[/tex]

To find: interval on which [tex]\left | q \right |[/tex] must fall

Solution:

[tex]\left | p \right |=7\sqrt{2}\\-7\sqrt{2}\leq p\leq 7\sqrt{2}\,\,(i)[/tex]

[tex]\left | p+q \right |=12\sqrt{3}\\-12\sqrt{3}\leq p+q\leq 12\sqrt{3}\,\,(ii)[/tex]

Subtract (ii) from (i)

[tex]-12\sqrt{3}+7\sqrt{2}\leq p+q-p\leq 12\sqrt{3}-7\sqrt{2}\\-12\sqrt{3}+7\sqrt{2}\leq q\leq 12\sqrt{3}-7\sqrt{2}\\\left | q \right |=12\sqrt{3}-7\sqrt{2}[/tex]

So, [tex]\left | q \right |[/tex] must fall in interval [tex][12\sqrt{3}-7\sqrt{2},\infty)[/tex]

Therefore, option B is correct.

Answer:

C

Step-by-step explanation:

To multiply matrices, the number of columns in the first matrix must equal the number of rows in the second matrix.

Matrix A has 2 columns.

Matrix B has 2 rows.

So the matrices can be multiplied.

Matrix A has 2 rows.  Matrix B has 1 column.  So the result will also have 2 rows and 1 column.

The first row is (5)(2) + (2)(3) = 16.

The second row is (3)(2) + (-1)(3) = 3.
