Answer:
16
Step-by-step explanation:
plugin -7 for where x is
f(-7)= (-3)(-7)-5
=21-5 is 16
The answer would be 42 degrees because the total of a triangle is 180 degrees. So you would subtract 180 and 42 (180-42) and that gives you 138 and since the two angles that are touching are the same
Step-by-step explanation:
6x-7
= 6×2-7
=12-7
=5
b) 3x
=3×2
=6
When a point P(a, b) is reflected about the y-axis, the coordinates of the reflected point are P'(-a, b).
Thus, the reflection of point (3, 7) is (-3, 7), as shown in the picture.
Answer: (-3, 7)
