Answer:
F. -5
Step-by-step explanation:
R = {5, x, 3, 8}
Sum of R: x + 16
S = {6, y, 4, 1}
Sum of S: y + 11
The sums are equal.
x + 16 = y + 11
x - y = 11 - 16
x - y = -5

EFG and GFH are a linear pair, m EFG = 4n+ 15, and mGFH = 2n + 39. What are mEFG and mGFH?
mEFG=
mGFH=
Answer:
Find value of n first to find out what the angle measures are.
Linear angles have a sum of 180°.
Angle EFG + Angle GFH = 180
4n + 15 + 2n + 39 = 180
6n + 54 = 180
6n = 126
n = 21
Substitute n into the angles.
Angle EFG = 4(21) + 15 = 99°
Angle GFH = 2(21) + 39 = 81°

Which postulate could we use to prove that the angles
The angle postulate that best defined angles CAB and CAD is; Supplementary Angles
What is the Angle Postulate?We know that there are different angle postulates such as Corresponding angles, complementary angles, supplementary angles and others.
Now, in this case we want to find the angle theorem that best describes angles CAB and CAD. Now, from the given image, it is clear that both angles form a straight line and we know that the sum of angles on a straight line equals 180 degrees.
Since both angles sum up to 180 degrees and we know that these angles are defined as supplementary angles which are linear pairs.

By critically observing the graph (see attachment), we can logically deduce that rectangle JKLM was transformed to rectangle J'K'L'M' by translating it 7 units to the right and 5 units up.

What is a log?
The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which a set number, base b, must be increased in order to create a specific number x, is represented by the logarithm of that number. The logarithm, in its most basic form, counts the number of times the same factor appears when multiplied repeatedly; for instance, since 1000 = 10 x 10 x 10 = 103, its "logarithm base 10" is 3, or log10 (1000) = 3. When there is no possibility of a mistake or when the base is irrelevant, as, in big O notation, the logarithm of x to base b is written as loga (x), logb x, or even without the explicit base, log x.

Can you please help me with this question I don’t understand it.From DA to the angle BAC
INFORMATION:
We have the next rhombus
And we must find the measure of
Knowing that DB = 10, BC = 13, and m∠WAD = 25°
STEP BY STEP EXPLANATION:
To find all measures, we need to use properties or the rhombus:
- DA: To find DA we need to know that all sides of the rhombus are equal. So, if BC measures 13, then DA measures 13 too.
- BW: To find BW we need to know that in a rhombus, diagonals bisect each other at right angles. That means, diagonals intersect in the middle. So, if DB = 10, then BW will be half of BD. BW = 10/2 = 5.
- WC: We can find it as one of the legs of the right triangle formed by BW, BC and WC. Where, BC is the hypotenuse.
[tex]\begin{gathered} 13^2=5^2+WC^2 \\ WC=\sqrt{13^2-5^2} \\ WC=12 \end{gathered}[/tex]So, WC = 12.
- Angle BAC: To find this angle, we need to use that the interior triangles formed in the interior of the rhombus are congruent. So, angle BAC is congruent with the angle DAC. Then, BAC = 25°.
ANSWER:
DA = 13
BW = 5
WC = 12
BAC = 25 degrees

Answer:
2. y = x + 13
Step-by-step explanation:
Your points are: (-4, 9) and (2, 15)
To write an equation of a line from two ordered pairs, you first find the slope (m)
To find the slope, you do y2 - y1 / x2 - x1
(-4 is x1, 9 is y1) (2 is x2, 15 is y2)
Plug in the numbers:
15 - 9 / 2 - (-4) ----------------------> 6/6 ----------> 1, m = 1
The next equation we'll use is y - y1 = m(x - x1)
and slope intercept form is y = mx + b
Pick either ordered pair to plug in the coordinates, but this time I'll use
(2, 15) -----> 2 is x1, 15 is y1
y - 15 = m(x - 2)
Since we already know the slope, m, we can simplify the equation.
y - 15 = 1(x - 2)
Distributive property
y - 15 = x - 2
Add 15 on both sides,
y = x + 13

The equation of the line that passes through the point (2,-3) and is parallel to the line 2x + 5y = 10 is y = - 2 / 5 x - 11 / 5
How to find the equation of a line?The equation of a line can be represented in various form such as point slope form, slope intercept form and standard form.
Therefore, let's find the equation of the line that passes through the point (2, -3) and is parallel to the line 2x + 5y = 10.
Hence, parallel lines have the same slope.
5y = -2x + 10
y = - 2 / 5 x + 2
Therefore, the slope of the line is - 2 / 5.
Let's find the y-intercept using the slope intercept equation.
y = mx + b

We have to determine the line that passes through the point (2,-3) and is parallel to the line 2x+5y=10
Parallel lines are known to have the same slope.
Firstly, we have to find its slope by the given line
⇒ 5y = -2x + 10
⇒ y = - (2/5)x + 2
Thus, the slope of the line is - 2/5.
Let the required equation of the line is y - y₁ = m(x -x₁ )
Here x₁ = 3, y₁ = 1 and m = -2/5
y - 1 = (-2/5)(x - 3)
y - 1 = (-2/5)x + 3(-2/5)
y = - (2/5)x - 6/5 +1
y = - (2/5)x - 11/5
Therefore, the required equation of the line is y = - (2/5)x - 11/5.
