Answer:
the average rate of change should be -10
Step-by-step explanation:
Step-by-step explanation:
You need to find six combinations of a and b such that a² + b² = 7.
a = 1, b = √6
a = √2, b = √5
a = √3, b = 2
a = 2, b = √3
a = √5, b = √2
a = √6, b = 1
X*.70=250
X is the original price, x times .70, 70%, because it's 30% off, 250 should be the answer
Answer: x=4
Step-by-step explanation: You have to distribute the negative signs
x - (4x-7)= 5x-(x+21)
x - 4x + 7 = 5x - x - 21
- 3x + 7 = 4x - 21
28 = 7x
X = 4
