66.7 - 6 x 14 + 99 x -6 = ?

Answer:

B. 8.2

Step-by-step explanation:

[tex] In\: \triangle ABC, \:\angle ABC= 90\degree \: \&\: BD\perp AC[/tex]

So, by geometric mean property.

[tex] BD = \sqrt {AD\times CD} \\

BD = \sqrt {13\times 4}\\

BD = \sqrt {52}\\

Next\: in \: \triangle BDC, \:\\

By\: Pythagoras \: theorem \\

m^2 = BD^2 + CD^2 \\

m^2 = (\sqrt {52}) ^2 + (4)^2 \\

m^2 =52 + 16\\

m^2 =68\\

m =\sqrt{68} \\

m = 8.24621125\\

m = 8.2 [/tex]

The correct options are given below;-

1) You can compare irrational numbers using rational approximations

2) Square roots can be compared and ordered by comparing and ordering the numbers underneath the radical symbol.

3) The closer together the numbers being compared, the more decimal places you need to use

All real numbers that are not mathematically rational are referred to as irrational numbers. On the other hand, irrational numbers cannot be expressed as the ratio of two integers.

1) Due to the fact that both rational and irrational numbers are a component of the real numbers and, as a result, have distinct positions on the real number line, it is possible to compare the values of two irrational numbers based on their relative positions on the number line.

2) Square roots can be sorted in their order of magnitude and can also be compared by comparing and sorting the numbers under the radical sign because the values of square roots are directly proportional to the value under the radical symbol.

3) The difference between two numbers that are very close to one another will be little. Therefore, the value of the difference between the numbers must be increased by increasing the detail or the number of decimal places of the numbers in order to clearly highlight the differences between two near numbers.

Similarly, It is necessary to increase the level of detail or the number of decimal places when comparing two numbers that are extremely close to one another.

So what youll wnat to do is figure out what the angle is.Its a right angle, a right angle is 90° . so what youll do is take 90° - 36° = 54°

Given :

A linear equations :

3x+4y = 8 .

She have completed the following steps :

3x+4y = 8

3x+4y-3x = 8-3x

4y = 8 -3x

To Find :

The equivalent equation which solves for y.

Solution :

General equation of line or equation which solves for y is given by :

y = mx +c

So , our next step should be dividing both sides by 4 .

[tex]\dfrac{4y}{4}=\dfrac{8}{4}-\dfrac{3x}{4}\\\\y=2-\dfrac{3x}{4}[/tex]

Therefore , equation which solves for y is [tex]y=2-\dfrac{3x}{4}[/tex] .

Hence , this is the required solution .

Complete Question:

The graph of the linear function g(x) = 2x - 2 is shown. The graph of f(x) = ()x is the graph of g(x) = 2x - 2reflected over the y-axis.

Which graph represents g(x)?

Answer:

[tex]f(x) = -2x - 2[/tex]

Step-by-step explanation:

Given

[tex]g(x) = 2x - 2[/tex]

Required

Determine f(x)

When a graph g(x) is reflected over the y axis, the resulting function is:

[tex]f(x) = g(-x)[/tex]

Solving for g(-x)

[tex]g(x) = 2x - 2[/tex]

[tex]g(-x) = 2(-x) - 2[/tex]

[tex]g(-x) = -2x - 2[/tex]

Recall that [tex]f(x) = g(-x)[/tex]

[tex]f(x) = -2x - 2[/tex]

The angle should be 74 degrees and they are supplementary

Step-by-step explanation:

It is 74 degrees because the two angles must add up to 180, so you can simply subtract 106 from 180 to get 74. The angles are supplementary because they add up to 180 degrees, while complementary angles only add up to 90 degrees

Greetings from Brasil...

According to the statement of the question, we can assemble the following system of equation:

X · Y = - 2      i

X + Y = 7       ii

isolating X from i and replacing in ii:

X · Y = - 2

X = - 2/Y

X + Y = 7

(- 2/Y) + Y = 7     multiplying everything by Y

(- 2Y/Y) + Y·Y = 7·Y

- 2 + Y² = 7X     rearranging everything

Y² - 7X - 2 = 0      2nd degree equation

Δ = b² - 4·a·c

Δ = (- 7)² - 4·1·(- 2)

Δ = 49 + 8

Δ = 57

X = (- b ± √Δ)/2a

X' = (- (- 7) ± √57)/2·1

X' = (7 + √57)/2

X' = (7 - √57)/2

So, the numbers are:

and

Answer:

3x - 5 = 2x + 6
