Answer:
Step-by-step explanation:
x+7=-3
x=-3-7=-10
x=-10
y-9=-14
y=-14+9
y=-5
Domain of (x,y)=(-10,-5)
Answer: it’s either 5x^3 -4x^2-7x or
-3x^3-4x^2-7x
Step-by-step explanation:
i put it in my calculator
The most common base used today is the decimal system which means 1 to 9.
The binary system is base two and it only uses the numbers 1 and 0. It does not go over 1. So base 5 is a number system that doesn’t go over four. It’s a little hard to understand until you do some questions relating to it.
Let the middle child be x
youngest child = x - 1
Oldest child = x + 1
(x - 1)^2 = 8(x + 1) + 4
x^2 - 2x + 1 = 8x + 8 + 4
x^2 - 10x - 11 = 0
(x - 11) * (x + 1) = 0
X = - 1 makes no sense. How can a middle child be - 1 years old?
x = 11
The youngest child is 10
The middle child is 11
The oldest child is 12
Check
=====
10^2 = 100
(8*12) + 4
96 + 4 = 100 So the results have been checked.
