Answer:
Step-by-step explanation:
Answer:
- x=6
- x=3
- x=9
Step-by-step explanation:
- 2(6)=12; there are 12 circles
- 2(3)+5=11; there are 11 circles on the right
- (9) + 12=21; there are 21 circles on the right
Answer:
y=-4x-24
Step-by-step explanation:
The equation of a line is always in the form y=mx+c. By subbing in the values given by the two points, we get:
0=-6m+c
-24=c
∴0=-6m-24
6m=-24
m=-4
∴the equation is: y=-4x-24
Because domain restrictions apply to this rational expression, x cannot be equal to {-2, 2}.
<h3>What is domain?</h3>
Domain restrictions are any points in the domain where the function will not have a value. This basically means that there is a point in the function where x will not work.
For the numerator, any value of x will suffice. We can have a value of 0 in the numerator, or a positive, negative, or decimal number.
However, the denominator cannot be equal to zero. This is due to the fact that a fraction bar represents division, and we cannot divide by zero.
Here,
x²-4=0
Add 4 to both sides:
x²-4+4 = 0+4
x² = 4
Take the square root of both sides:
√x² = √4
x = 2 or x = -2
The x cannot be equal to {-2, 2} as domain restrictions apply to this rational expression.
