Answer:
(7, 0 )
Step-by-step explanation:
Given the 2 equations
y = - 2x + 14 → (1)
y = 2x - 14 → (2)
Since both equations express y in terms of x we can equate them
2x - 14 = - 2x + 14 ( add 2x to both sides )
4x - 14 = 14 ( add 14 to both sides )
4x = 28 ( divide both sides by 2 )
x = 7
Substitute x = 7 into (2) for corresponding value of y
y = (2 × 7) - 14 = 14 - 14 = 0
Solution is (7, 0 )
Answer:
12.5cm
Step-by-step explanation:
Answer:
400 square yards
Step-by-step explanation:
square part = l x w = 20 x 15 = 300
triangle part = 1/2 b x h = 1/2 (20) (10) = 100
300 + 100 = 400
D because you know it can’t be a or b and the bigger number goes first
