In circle O, RT and SU are diameters. If m = m, what is m? 47° 52° 64° 87°
vlada-n [284]
From the given figure, it can be seen that 13x = 15x - 8 because they are vertical angles and thus are equal.

13x = 15x - 8
15x - 13x = 8
2x = 8
x = 8/2 = 4

Thus, 15x - 8 = 15(4) - 8 = 60 - 8 = 52.

RT is a diameter, which means that mRT = 180

mRV + mVU + 52 = 180

mRV + mVU = 180 - 52 = 128

Now, given that mRV = mVU,

Thus, 2mVU = 128

Therefore, mVU = 128 / 2 = 64°

Consider the function f(x)=-2x+5 what is f(5) enter your answer in the box
Oliga [24]

The value of f(5) is f(5)=-5

Step-by-step explanation:

The function is f(x)=-2x+5

To find f(5) substitute x=5 in f(x)=-2x+5

f(5)=-2(5)+5

Multiplying the terms, we get,

f(5)=-10+5

Adding the terms, we get,

f(5)=-5

Thus, the value of f(5) is f(5)=-5

State the Rules for Reflection across the x-axis and across the y-axis
prisoha [69]

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).
