Answer:
OC. 5x + 45 + 7y + 14 - X, OE. 4x + 7y + 11
Step-by-step explanation:
Because, 5(x + 9) is 5x + 45 and 7(y + 2) is 7y + 14 and so you simplify by simplifying the like terms for example 5x - x = 4x 45 + 14 = 59 and 7y stays the same.
Answer:
option 3, 45
Step-by-step explanation:
3x - 9° + 30° + 24° = 180° (angle sum property of a triangle)
3x - 9° + 54° = 180°
3x + 45° = 180°
3x = 180° - 45°
3x = 135°
x = 135/3
x = 45°
therefore, option 3 is the correct option
Answer:
(1, - 2 )
Step-by-step explanation:
Given the 2 equations
y = - 4x + 2 → (1)
y = x - 3 → (2)
Since both equations express y in terms of x, equate the right sides
x - 3 = - 4x + 2 ( add 4x to both sides )
5x - 3 = 2 ( add 3 to both sides )
5x = 5 ( divide both sides by 5 )
x = 1
Substitute x = 1 in (2) for corresponding value of y
y = 1 - 3 = - 2
Solution is (1, - 2 )
