Answer:
a = -1 b=0 and c=1
Step-by-step explanation:
-x^2 +0x+1
This is in the form
ax^2 +bx+c
a = -1 b=0 and c=1
Answer: $4
The cost of an 8x10 piece is $2, and 16x20 is just 2 times that amount, multiply the cost.
A=15 and the angles are 100 degrees. Thats because 6a=10=3a=55 due to alternate angles equal the same angle. so if you algebraically solve for a, you eventually get a=15. then plug in your a value into either or given equations. (i.e.. 6(15)+10= 100
