Find the measure of angle r

Mathematics
1 answer:
SIZIF [17.4K]3 years ago
4 0

Answer 121°

Step-by-step explanation:

All triangles have an interior angle sum of 180.

From this you can subtract 103 and 18 to get 59.

The line that r is connected to is 180° (hence being a line)

This means you can subtract 59 from 180 to get 121°

Without graphing the linear functions, find the coordinates of the point of intersection of their graphs: y=3x−11 and y=4
egoroff_w [7]

Answer:

(5, 4)

Step-by-step explanation:

given the 2 equations

y = 3x - 11 → (1)

y = 4 → (2)

Substitute y = 4 into (1)

3x - 11 = 4 ( add 11 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

solution is (x , y) = (5, 4)

Identify the type of transformation given the rule N(x,y) = (-x,y)
denis23 [38]

Hello!

If the domain of the function is negative, the translation occurring has to be a reflection over the x-axis or y-axis.

Since the translation is affecting the x-values, it has to be a reflection over the y-axis. Similarly, if the translation affects the y-values, it translates over the x-axis.  

Therefore, the type of transformation given by the rule is a reflection over the y-axis.
