Explanation
For the given question, we will have to apply the rule for lines intersecting inside a circle
We will simply apply the rule
![m Where[tex]\begin{gathered} mPK=2\times32.8=65.6^0 \\ mWe can now get the value of the measure of arc RA[tex]\begin{gathered} 71.4^0=\frac{1}{2}(mRA+65.6^0) \\ cross\text{ multiplying} \\ 2\times71.4^0=mRA+65.6 \\ \\ mRA=142.8^0-65.6^0 \\ mRA=77.2^0 \end{gathered}](https://tex.z-dn.net/?f=m%20Where%5Btex%5D%5Cbegin%7Bgathered%7D%20mPK%3D2%5Ctimes32.8%3D65.6%5E0%20%5C%5C%20mWe%20can%20now%20get%20the%20value%20of%20the%20measure%20of%20arc%20RA%3Cp%3E%3C%2Fp%3E%5Btex%5D%5Cbegin%7Bgathered%7D%2071.4%5E0%3D%5Cfrac%7B1%7D%7B2%7D%28mRA%2B65.6%5E0%29%20%5C%5C%20cross%5Ctext%7B%20multiplying%7D%20%5C%5C%202%5Ctimes71.4%5E0%3DmRA%2B65.6%20%5C%5C%20%20%5C%5C%20mRA%3D142.8%5E0-65.6%5E0%20%5C%5C%20mRA%3D77.2%5E0%20%5Cend%7Bgathered%7D)
Thus, the measure of the arc RA is 77.2 degrees
Option D is correct
We know that
As the midpoint is a point on the perpendicular line, we can solve by eliminating the other equations, like this:
a) Check if the point (-1,-2) is on the line y=-4x-4:
for x=-1
y=-4*(-1)-4--------> y=0
0 is not -2--------> that is not the equation
b) Check if the point (-1,-2) is on the line y = −4x − 6:
for x=-1
y=-4*(-1)-6--------> y=-2
-2 is equal to -2--------> that is the equation
c) Check if the point (-1,-2) is on the line y = x – 4
for x=-1
y=-(-1)-4--------> y=-5
-5 is not -2--------> that is not the equation
d) Check if the point (-1,-2) is on the line y = x – 6
for x=-1
y=-(-1)-6--------> y=-7
-7 is not -2--------> that is not the equation
therefore
the answer is
y = −4x − 6:

Answer:
Terms
Step-by-step explanation:
Hello!
The expression 2x +5 has two different terms: 2x and 5
<h3><u>
Terms:</u></h3>
Terms are values in an expression that are different from each other. They are values with different coefficients.
For example:
- 2x has a coefficient of 2, because 2x = 2(x)
- 5 has a coefficient of 1 because 5 = 1(5)
<h3><u>Like Terms:</u></h3>
Like terms are values with the same factors or coefficients.
Let's use an example equation: 2x + 5 + 7x - 9
- 2x and 7x are like terms, because they have a factor of x, which simplifies to 2x + 7x = 9x
- 5 and -9 have the same factor of -1, so if we simplify: 5 + (-9) = 5 - 9 = -4
- Combining the two terms we have 9x - 4
