Answer:
point lies on circle
Step-by-step explanation:
Substitute the coordinates of the point into the left side of the equation and if equal to the right side then point lies on circle.
(4 - 1)² + (2 + 2)² = 3² + 4² = 9 + 16 = 25 = right side
Then point (4, 2 ) lies on the circle
Answer:
5x +
y = 3/8
Step-by-step explanation:
Add
to both sides
+ y = 3
Divide both sides by 8
5x +
y = 3/8
3(n+5) < 3/4(n)
The three is multiplied by n+5. Whenever you see "is equal to/greater/less than," that is where you put your =, >, or < signs. Your variable, "n" represents the number. So three-fourths of the number is the same as multiplying the number by three-fourths.
Start with the sum of x and 9, giving the expression

This is divided by 2 so

This equals 3x so the equation is

This can the be solved.
Multiply both sides by 2 to get

Then take x from both sides

Divide by 5 to get the value for x
Step-by-step explanation:
the equation :
Hn = 7n + 3
where :
Hn : the height of trees at year to-n
n : year to-n (n = 1,2,3,...)
so, the rate of change : increasing 7 feet per year.
