Answer:
a=-4, b=-4. (-4, -4).
Step-by-step explanation:
-3a+7b=-16
-9a+5b=16
-------------------
-3(-3a+7b)=-3(-16)
-9a+5b=16
---------------------------
9a-21b=48
-9a+5b=16
------------------
-16b=64
b=64/-16
b=-4
-3a+7(-4)=-16
-3a-28=-16
-3a=-16+28
-3a=12
a=12/-3
a=-4
Answer: 80 feet.
Step-by-step explanation:
1. As you can see in the figure, triangle ABC and the triangle DFG are similar.
2. The scale of factor of triangle ABC to triangle DFG is the following:
3. Therefore, the lenght of the side DG of the trinagle DFG is:
4. The perimeter of the triangle DFG is:
5. Therefore, she would need 80 feet of fence.
Answer:
The cost per costumer is 10 + x
Step-by-step explanation:
I hope this helps! :)
Rational zero theorem is all combinations of p(factors of the constant) divided by q(factors of the first coefficient)
factors of 8 are 1, 2, 4, 8
factors of 2 are 1, 2
so all possible rational zeros are all combinations of p/q
+/- 1/1, 1/2, 2/1, 2/2, 4/1, 4/2, 8/1, 8/2
Now there are some repeats in there so you have to leave those out and once we do that we get
+/- 1, 1/2, 2, 4, 8
Remember all those are plus OR minus
