It’s B ) THE SLOPE IS POSITIVE
Answer: the second one
open circle = < or >
closed circle = <> or equal to
Step-by-step explanation:
The lines through side AB and side AC tell us that both sides are congruent, and by the isosceles triangle theorem that means that m∠ABC = m∠ACB so
m∠ABC = 40
Since all 3 angles in a triangle always add up to 180, we know that
(40) + (5x) + (2y + 20) = 180
We substitute our known value for 5x and solve for y:
40 + 40 + 2y + 20 = 180
2y + 100 = 180
subtract 100 from both sides
2y = 80
divide both sides by 2 to get our answer:
y = 40
The value of 2 in 2783 (2000) is 10 times the value of two in 7283 (200).

Answer:
(- 1, - 5 )
Step-by-step explanation:
Given the 2 equations
y = 3x - 2 → (1)
6 + y = - x → (2)
Substitute y = 3x - 2 into (2)
6 + 3x - 2 = - x
4 + 3x = - x ( add x to both sides )
4 + 4x = 0 ( subtract 4 from both sides )
4x = - 4 ( divide both sides by 4 )
x = - 1
Substitute x = - 1 into (1) for corresponding value of y
y = 3(- 1) - 2 = - 3 - 2 = - 5
solution is (- 1, - 5 )
