X + 105 = 180
x= z (congruent)
180-z =y
Answer:
4y²−38y−20
Step-by-step explanation:
(y−10)(4y+2)
=(y+−10)(4y+2)
=(y)(4y)+(y)(2)+(−10)(4y)+(−10)(2)
=4y²+2y−40y−20
=4y²−38y−20

Answer:

Step-by-step explanation:
To find the slope, use the equation

where (-1, 7) and (4, -1) is (x1, y1) and (x2, y2) respectively.
Hence, the slope will be
