Switch the second equation to equal y so...
y=-2x-3
then plug in for y in the first equation
2x+4(-2x-3)=6
2x-8x-12=6
-6x=18
x=-3
now plug in for y
2(-3)+y=-3
-6+y=-3
y=3
answer (-3,3)

Answer:
Find the domain by finding where the equation is defined. The range is the set of values that correspond with the domain.Domain: [4,∞),{x|x≥4}[4,∞),{x|x≥4}Range: [0,∞),{y|y≥0}
Answer:
p(0) = 800
p(8) = 997
Step-by-step explanation:
p(t) = 800 * (1.028)^t
The current price is when t=0
p(0) = 800 * (1.028)^0
= 800(1)
= 800
The price in 8 years
p(8) = 800 * (1.028)^8
=997.7802522414861936754688
To the nearest dollar
= 998
