Step-by-step explanation:
making x subject in eq 1
x= (-1-9y)/-14
substituting the value of x in eq 2
17(-1-9y/-14)=7+9y
(-17-153y)/-14=7+9y
-17-153y=-98-126y
-17+98=153y-126y
81=27y
y=3
substituting this value of y in eq 1
-14x=-1-9(3)
-14x=-28
x=2
(x,y) = (2,3)
B 56

Answer:
The answer to your question is below
Step-by-step explanation:
1.- 3x + 54 = 5x + 14
3x - 5x = 14 - 54
-2x = - 40
x = 20
2.- I can not see it
3.- Yes, they are paralleles
because 180° = 119 + 61 = 180°
4.-
180° - 82 - 31 = 67°
180° - 67 - 98 = 15°
q = 15°
5.- 100 - x + 30 + 4x + 7x = 180
10x = 180 - 100 - 30
10x = 50°
x = 5
7x = y
y = 7(5)
y = 35°
6.-
55 + 4x + 2x - 5 = 180
6x = 180 - 50
6x = 130
x = 21.7°
7.-
slope = (1 - 2) / (3 - 0)
m = -1 / 3
( y + 1 ) = -1/3(x - 0)
8.-
9.-
slope = 3/7
P (-14 , -3)
( y + 3) = 3/7(x + 14)
10.-
Point (3,2)
A (2, 10)
B (4, 7)
slope = (7 - 10) / (4 - 2)
m = -3/2
New slope = 2/3
(y - 2) = 2/3(x - 3)
