Answer: No. The answer to this system is y=−85 and y=5, and if you plot that and (3,4) on a graph (I did it on desmos), you will see that it is one square down from the system, meaning it is not a solution to the system. Hope this helps and have a great day!
Answer:
(-3,0) and (2,-1)
Step-by-step explanation:
For (-3,0) x=-3 , y=0:
Putting in given inequality :
y < x2 - 4x + 3
0 < -3^2 -4*-3 +3 ("-" into "-" becomes "+")
0 < 9 +12 +3
0< 24 true
For (2, -1) x=2 , y= -1
Putting in given inequality :
y < x2 - 4x + 3
-1 < 2^2 -4(2) +3
-1 < 4 -6 +3
-1 < 7-6
-1 < 1 true
For (1,0) x=1 y=0
Putting in given inequality :
y < x2 - 4x + 3
0 < 1^2 -4(1)+ 3
0< 1- 4 + 3
0< 4 - 4
0 < 0 false
Hence, (-3,0) and (2,-1) are in the solution set of y < x2 - 4x + 3.

Answer:
i think its just the last one
Step-by-step explanation:
because the first two are all real numbers and the thrid equals one
4/5=0.8
since 4/5 is an inquelvient fraction it gets turned into a decimal
Answer:
a) 0.04
b) 0.08
Step-by-step explanation:
Part a)
Divide the price of a pack by the number of stickers in a pack to get the price of one sticker.
$2/50 = $0.04/1
One stickers costs $0.04.
Part b)
Calculate 80% more than the price of one sticker.
80% in decimal form is 0.8. 80% more than the price is calculated with the factor 1.8.
($0.04)(1.8) = $0.072
Round 0.072 up because is rounded down, the profit is less than 80%.
0.072 => 0.08
Each sticker would need to be sold for $0.08.
