Answer:
x = y = - 1
Step-by-step explanation:
y = - 2x - 3
y = 7x + 6 -----> equation 1.
So,
7x + 6 = - 2x - 3
7x + 2x = - 3 - 6
9x = - 9
Divide 9 on both sides,
9x / 9 = - 9 / 9
x = - 1
Substitute x = - 1 in equation 1,
y = 7x + 6
= 7 ( - 1 ) + 6
= - 7 + 6
= 6 - 7
y = - 1
Therefore,
x = y = - 1
Answer:think as it as coordinates on a graph. Time=x Amount=y. So if the time is 0 and the amount is 60 you would graph a point on (0,60)

Answer:
x = 14
Step-by-step explanation:
∠ DCA and ∠ BCF are adjacent angles and sum to 180° , then
∠ DCA = 180° - 124° = 56°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
6x is an exterior angle , then
6x = 2x + 56 ( subtract 2x from both sides )
4x = 56 ( divide both sides by 4 )
x = 14
