Answer:

Because you can't divide by zero.

Step-by-step explanation:

If x = -2, it makes the denominator 0. This will result in the equation being undefined because you can't have zero in the denominator.

Find an exponential function that fits the information (hint: putting them in a table may help you see).
Vilka [71]

Answer:

f(x)=8*(3.5)^x

Step-by-step explanation:

2=98

3= 98r

4= 98r^2

5= 98r^3

6= 98r^4

98r^4/98, 98 crosses out and its just r^4. r^4= 14706.125/98

r=3.5

So you plug that in and you get f(x)=8*(3.5)^x

I hope this helped. XD

What is the quadratic in vertex form that has a vertex of (-1, 5)<br><br> Options in image
dimaraw [331]

Answer:

Third option

y = (x+1) ^ 2 + 5

Step-by-step explanation:

In this case we must write a quadratic equation in the vertex form.

We have the vertice. (-1, 5)

We know that the vertex form for a quadratic equation is:

y = (x-h) ^ 2 + k.

Where (h, k) is the vertex.

So if the vertex is (-1, 5), the equation sought is:

y = (x-(-1)) ^ 2 + 5

y = (x+1)) ^ 2 + 5

Therefore the answer is the Third option.

isaac has a piece of rope that is 5 yards long. into how many 1/2 yard pieces of rope can isaac cut the rope
marusya05 [52]
What you have to do is figure out how many half inches you need to have to figure out how many half inches equal 5 yards. Therefore if there are 12 inches in a foot, then that would be 24 half inches. So..... three feet equal 1 yards. So multiply 3 by 24. 3x24=72 so you would need 72 half inches

Three even numbers sum up to 162. the smallest is half the largest and the middle number is 3/4 the largest. what are the three
Scrat [10]
Lets name the largest number as x 
smallest number is half the largest , therefore its x/2 = 0.5x
then middle number is 3/4 the largest , therefore its 3/4x = 0.75x
the sum of the three numbers are 162
the three numbers added are 
x + 0.5x + 0.75x = 162
2.25 x = 162
x = 72
the largest number is 72
then middle number 0.75 x = 0.75 x 72 = 54
smallest number is 0.5x = 0.5 x 72 = 36
answer is  -   36,54,72
