Answer:
18
Step-by-step explanation:
9 x 2 = 18
radius x 2 = diameter
3x + 12 - 6x < -9
-3x +12 < -9
-3x < -21
x < 7

The equations y = x² - 2x + 1 and 2x - y = 2 intersect at the points (1, 0) and (3, 4)
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given that the quadratic function intersecting a linear function at points (1, 0) and (3, 4)
This means that this points lie on both functions.
y = x² - 2x + 1 and 2x - y = 2
For point (1, 0):
y = 1² - 2(1) + 1 = 0; 2(1) - 0 = 2
For point (3, 4):
y = 3² - 2(3) + 1 = 4; 2(3) - 4 = 2
The equations y = x² - 2x + 1 and 2x - y = 2 intersect at the points (1, 0) and (3, 4)

Answer:There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?
Step-by-step explanation
There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?
Legs of a chicken = 2
Legs of a rabbit = 4
Total heads = 72
Total legs= 200
Let's assume that each of them has minimum 2 legs.
So 72*2 = 144 legs
Remaining legs: 200-144= 56
These remaining legs belong to rabbit because rabbit has 4 legs each.
2*Rabbits= 56
Rabbits= 56/2 = 28
Out of 72, 28 are rabbits. So there are 72-28= 44 chicken.
