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:
The answer would be 10 tickets because 400 divided by 40 equals 10
Step-by-step explanation:
Answer:
(1, 0 )
Step-by-step explanation:
using the rule of logarithms
x = n ⇒ x =
, then
y =
(x + 2) - 1
to find the zero let y = 0 , that is
(x + 2) - 1 = 0 ( add 1 to both sides )
(x + 2) = 1 , then
x + 2 =
= 3 ( subtract 2 from both sides )
x = 1
the zero is (1, 0 )
Sorry cant help you, that's a tough nut to crack! good luck though!
