Parentheses first. 1-4= -3. 4-3=1. 1-2=-1.
The answer is -1.
Answer:
1. (2,3)
2. (7,-2)
3. (-4,-1)
4. No solutions
Step-by-step explanation:
Solve using substitution or elimination.
Answer:
y=-6x-24
Step-by-step explanation:
just expand
y+6=-6x-18
then move the six from the left to the right
y=-6x-24
Answer:
Exponential decay.
Step-by-step explanation:
The magnitude of the base (also known as the "common factor") tells us whether a given exponential equation represents growth or decay.
Standard equation for expo. growth: y = 3(b)^x, where b is the base.
If 0<b<1, we have expo. decay; if 1<b, we have expo. growth.
Thus, y = 3(0.5)^x represents expo. decay.
Answer:
A = amount left
so i think the answer could be:
A=9-3x
