Complete the statement. The drawing is not to scale. If mangle upper D upper G upper F = 84°, then mangle upper D upper E upper F = ___. Two adjacent triangles are shown.

-4(x + 7) < 3(x - 2)

Let's simplify this inequality

-4x - 28 < 3x - 6

Subtract 3x from both sides and add 28 to both sides

-7x < 22

Answer choice B is correct

Answer:

-7x < 22

Step-by-step explanation:

1. -4(x+7) < 3(x-2)

distribute -4 to x and 7, distribute 3 to x and -2.

2. -4x-28 < 3x-6

add 28 to 28 to cancel it out, add 28 to -6.

3. -4x < 3x+22

subtract 3x from 3x to cancel it out, subtract -3x from -4x.

4. -7x < 22

the final product! the answer is B. -7 < 22. since there was no multiplication or division, there's no need to switch < to >. hope this helps! :)

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]

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:

Hi there!

Your answer is:

17= 2A-5

Alonzo is 11

Step-by-step explanation:

Frank=2A -5

Frank = 17

17= 2A-5

A = Alonzo's age

Alonzo's age is:

17= 2A-5

+5

22 = 2A

Answer:

A.  6

Step-by-step explanation:

Segment AB is on the line y = 2 and is 3 units long.

Point C is on the line x = −1.

FIND:

If the area of ΔABC is 6 square units, then find a possible y-coordinate of point C.

SOLUTION:

Area of a triangle = 1/2 b * h

segment AB is a horizontal line

the base of our triangle and point C is somewhere on the height.

If we can find the height of the triangle, we can add or subtract that height from y = 2 to get the possible y coordinate of point C.

We know that the x coordinate is -1 so,

6 = 1/2 (3) h

12 = 3h

h = 4

we can either add 4 or subtract 4 to the y coordinate of 2 to get the possible y coordinate of point C.

option 1

2 + 4 = 6 so the coordinate for C could be (-1, 6) or

option 2

2 - 4 = -2 so the coordinate for C could also be (-1, -2).

Since -2 is not in our choices but 6.

therefore,

the answer would be A. 6

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.

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]
