Answer:
(
, -
)
Step-by-step explanation:
given the 2 equations
2x + 3y = - 4 → (1)
4x - y = 11 → (2)
Rearrange (2) expressing y in terms of x, that is
y = 4x - 11 → (3)
Substitute y = 4x - 11 into (1)
2x + 3(4x - 11) = - 4
2x + 12x - 33 = - 4
14x - 33 = - 4 ( add 33 to both sides )
14x = 29 ( divide both sides by 14 )
x = 
Substitute this value into (3) for corresponding value of y
y = (4 ×
) - 11 =
-
= -
= - 
solution is (

Answer:
15
Step-by-step explanation:
Simplify the following:
8×9 - 6×7 - 15
8×9 = 72:
72 - 6×7 - 15
-6×7 = -42:
72 + -42 - 15
72 - 42 - 15 = 72 - (42 + 15):
72 - (42 + 15)

Answer: 15
Step-by-step explanation:
Supplement= 180°- 13°
167° Answer
Answer:
19.0681
Step-by-step explanation:
Given in the question that,
angle from ted to the dog = 60° with the ground
height of ted from the ground = 16ft
To find,
distance between dog and the door of ted's building
Considering the scenario make a right angle triangle:
<h3>By using pythagorus theorem:</h3>
Tan 40 = opposite / adjacent
Tan 40 = height / distance between dog and the door
Tan 40 = 16ft / x
x = 16 / tan40
x = 19.068057
x ≈ 19.0681 (nearest to thousand)
So, the dog need to walk 19.0681ft to reach the open door directly below Ted.
