Answer:
y= -1/2
x=3/2
Step-by-step explanation:
first isolate x
2x+4y=1
2x=1-4y
x=(1-4y)/2
subsitute it in the second equation

Hope this helps :)
Answer:
7) Decay
8) Growth
9) Growth
10) Growth
Step-by-step explanation:
7) As <em>x </em>increases, <em>y </em>is decreasing because as you add more value to the exponent, 1/3 gets smaller and smaller.
8) As <em>x </em>increases, <em>y </em>is increasing because as you add more value to the exponent, 2 gets bigger and bigger.
9) As <em>x </em>increases, <em>y </em>is increasing because as you add more value to the exponent, 2 gets bigger and bigger.
10) As <em>x </em>increases, <em>y </em>is increasing because as you add more value to the exponent, 2 gets bigger and bigger.
