An equation which can be used to solve the given system of equations is 3x⁵ - 5x³ + 2x² - 10x + 4 = 4x⁴ + 6x³ - 11.

Given the following data:

y = 3x⁵ - 5x³ + 2x² - 10x + 4

y = 4x⁴ + 6x³ - 11

A system of equations can be defined an algebraic equation that only has two (2) variables and can be solved simultaneoulsy.

Equating the given equations, we have:

y = y

3x⁵ - 5x³ + 2x² - 10x + 4 = 4x⁴ + 6x³ - 11

3x⁵ - 5x³ + 2x² - 10x + 4 - (4x⁴ + 6x³ - 11) = 0

3x⁵ - 5x³ + 2x² - 10x + 4 - 4x⁴ - 6x³ + 11 = 0

3x⁵ - 5x³ + 2x² - 10x + 4 - 4x⁴ - 6x³ + 11 = 0

3x⁵ - 4x⁴ - 11x³ + 2x² - 10x + 15 = 0

Answer:

[tex]8 \frac{1}{25} [/tex]

Step-by-step explanation:

[tex]4 \frac{3}{5} + 3 \frac{11}{25} \\ (4 + 3) + ( \frac{3}{5} + \frac{11}{25} ) \\ 7 + \frac{26}{25 } \\ 7 + 1 \times \frac{1}{25} \\ 8 \frac{1}{25} [/tex]

[tex]4 \frac{3}{5} + 3 \frac{11}{25} [/tex]

the simplest form.

[tex] \frac{23}{5} + \frac{86}{25} [/tex]

[tex] = \frac{(23 \times 25) + (86 \times 5)}{5 \times 25} [/tex]

[tex] = \frac{575 + 430}{125} [/tex]

[tex] = \frac{1005}{125} [/tex]

[tex] = 8 \frac{1}{25} [/tex]

The combined height of the dolls when the tallest of a collection of wooden dolls stands 1 meter tall, and each successive doll is half as tall as the one before it is 2 meters.

Geometric sequence is the sequence in which the next term is obtained by multiplying the previous term with the same number for the whole series.

It can be given as,

[tex]S=\dfrac{a(1-r^n)}{1-r}[/tex]

Here, [tex]a_1[/tex] is the first term of the sequence, n is the number of terms, and r is the common ratio.

The tallest of a collection of wooden dolls stands 1 meter tall, and each successive doll is half as tall as the one before it.

The second doll is half of the first doll. Thus, the height of the second doll is,

[tex]a_2=\dfrac{1}{2}\\a_2=0.5\rm\;m[/tex]

Similarly, height of third doll,

[tex]a_3=\dfrac{0.5}{2}\\a_3=0.25\rm\;m[/tex]

Here, we see a pattern or sequence in the height of doll,

1,0.5,0.25......

For this series, the value of first term [tex]a_1[/tex] is 1, the number of dolls n is 8 and common ratio r is 0.5. Put the value in the above formula,

[tex]S=\dfrac{1(1-0.5^8)}{1-0.5}\\S=1.992\\S\approx 2\rm\; meters[/tex]

Thus, the combined height of the dolls when the tallest of a collection of wooden dolls stands 1 meter tall, and each successive doll is half as tall as the one before it is 2 meters.

Answer:

It has to be 40° or 55°, I think.

sorry if wrong.

Answer:

60 degrees

Step-by-step explanation:

First of all, we have to set up an equation to solve this. The angles of a triangle add up to 180 degrees. We need to find the internal angle of C, which would be 180-(10x-45).

For our equation, we can set 3x+4x+[180-(10x-45)] equal to 180.

Add like terms:

7x+[180-(10x-45)] = 180

Distribute:

7x+180-10x+45 = 180

Add like terms once again:

-3x+225 = 180

Subtract 225 on both sides:

-3x = -45

Divide by -3 on both sides:

x = 15

Plug in 15 for x in the value 4x:

<B = 60 degrees

Answer:

"A solution to 8 = -x + 10 is 2" is the only correct option.

The given statement is false statment because the line drawn has an inclination of 45°.

Given that,
On a grid, moving from 0,0 to 4,4 makes a line at a 90-degree angle. whether the statement is true or false is to be justified.

A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.

Here,
According to the question,
Moving from 0,0 to 4,4
Calculating the slope,
m = 4 - 0 / 4 - 0
m = 1
m = tanФ = 1
tanФ = 1
tanФ = tan 45°
Ф = 45°

Thus, the given statement is a false statment because the line drawn has an inclination of 45°.

∠D = 90°

∠C = 80°

Step-by-step explanation:

∠D = 90° (right angle)

All right angles = 90°

∠C = 80° (sum of all angles = 360°)

110 + 80 + 90 + ∠C = 360°

280 + ∠C = 360

∠C = 80°

The most improbable simulation for this coin is the heading when a coin is tossed 20 times will be 15.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A coin is biased to display heads 75% of the time.

It is tossed 20 times, and the outcomes are recorded.

Then the probability of getting heads when a coin is tossed 20 times. Then we have

After translation, M would be at (-2.2), N would be at (-2,-1), and O would be at (-4,-1).

Explanation:

To get you started, as it isn't too difficult, the first thing that you should do is write down the coordinates for each point.

As an example, I'll use point O which is located at (2,3).

The translation is [-6, -4], which simply means to translate your x-value left 6(as it is negative) and your y-value down 4.

In the case of O(2,3), your translated point would be at (-4,-1).

Step-by-step explanation:

Answer:

x = 2/9 or 0.2

Step-by-step explanation:

6 x 2 - 54x = 0

(6x2) = 12

12 - 54x = 0

Rearange the terms

-54x + 12 = 0

subtract 12 from both sides

-54x = -12

Divide both sides by the same factor

-54x/54 = -12/-54

then simplify

x=2/9 or 0.2
