One of the ways of dividing polynomials is by synthetic division

The divisor of the synthetic division is x + 5

From the question, we understand that:

Entry -5 is on the outside to the left of the shape

The entry represents the zero of the divisor.

Next, we set this entry to the variable (assume the variable is x)

So, we have:

[tex]x = -5[/tex]

Add 5 to both sides

[tex]x + 5= 0[/tex]

Hence, the divisor of the synthetic division is x + 5

Based on the information given, it should be noted that the cost of the pretzel is $0.04.

Let the coke be represented by c.

Let the pretzel be represented by p.

Based on the information,

c = p + 2 ..... i

c + p = 2.08 ... ii

p + 2 + p = 2.08

2p + 2 = 2.08

2p = 2.08 - 2

2p = 0.08

p = 0.08/2 = 0.04

Therefore, c = 2 + 0.04 = 2.04

x = 2[tex]\sqrt{10}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

x² + 9² = 11²

x² + 81 = 121 ( subtract 81 from both sides )

x² = 40 ( take square root of both sides )

x = [tex]\sqrt{40}[/tex] = [tex]\sqrt{4(10)}[/tex] = [tex]\sqrt{4}[/tex] × [tex]\sqrt{10}[/tex] = 2[tex]\sqrt{10}[/tex] ≈ 6.32 ( to 2 dec. places )

You should plot an arrow, with open-circle, starting in the number 9. See the image attached.

It is an expression mathematical that represents a non-equal relationship between a number or another algebraic expression. Therefore, it is common the use of follow symbols: [tex]\leq[/tex] (less than or equal to), [tex]\geq[/tex] (greater than or equal to), < (less than) and > (greater than).

The solutions for inequalities can be given by: graph in a number line or numbers. Your question requests a graph solution, but it is necessary to find a number solution to plot it in the graph.

The constant of proportionality is 1/4.

Step-by-step explanation:

Keep in mind that the constant of proportionality can always be found by dividing any y value by any x value, as long as the values are in the same row. For example, in this table, the constant of proportionality would be 1/4, as, in the first row, the y value is 2 and the x value is 8, and 2/8 equals 1/4.

Answer:

It depends on what you prefer

Step-by-step explanation:

personally, i prefer percentages because sometimes fractions can get confusing. imagine someone saying " we have 1/2 chance of rain today and 1/8 of it will be scatterd showers while for 1/16th of the day will be clear."

I believe i got my point across

The probability can be expressed in the form of percentages as well as fractions form.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have:

A local weather forecaster uses percentages to describe the chances of precipitation.

As we know, probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Let the chance of rain is 50% for tommorrow.

The probability for rain = 50%

We can write the above probability in the a form of fraction.

P = 50% = 50/100

P = 1/2

Thus, the probability can be expressed in the form of percentages as well as fractions form.

Answer/Step-by-step explanation:

The given function is linear. The curve will be a straight line.

Find two points. Plot them on a graph sheet. Join them with the help of a straight Line.

Given - y = 1/2 x - 5

Find the Y - intercept

At x=0;y=1/2(0)−5

(0,−5)  is one of the points.

For the other point we would normally find the X-intercept.

If we did that with this equation we would create a fraction. It may be little difficult to fix that point. So, instead, assign a value to y so that you get a whole number as x-co-ordinate.

In our case we shall assign +1 as y-co-ordinate.

At y=1;1=1/2x−5

1/2x−5=1

1/2x=1+5=6

x=6×2=12

(12,1) is another point.

Plot the points

(0,−5) and (12,1)

Join them with a straight line. You get the curve.
