Can the quadratic polynomial x2+kx+k have equal zeroes for some odd integer k>1

No.
The only value that can be put in K that would have the same zeros would be 4 but 4 is not an odd integer. If there was an odd integer that the sum and product would be the same then it would lie on the x-axis. but only 4 fits the criteria.

Arada [10]
X = the brother
c = carly

c = 3x
c + x < = 24

now we sub
3x + x < = 24
4x < = 24
x < = 24/4
x < = 6 ...oldest age the brother can be is 6

Point JJJ is located at (-4, 4)(−4,4)left parenthesis, minus, 4, comma, 4, right parenthesis. Select all of the following that a
In-s [12.5K]

Answer:

(-4, 8), (-4, 0), (0, 4) and (-4, 0)

Step-by-step explanation:

Given that point J is located at (-4, 4). The point4 units from point J can either be up, down, left or right. Hence:

The point 4 units up of point J = (-4, 4 + 4) = (-4, 8)

The point 4 units down of point J = (-4, 4 - 4) = (-4, 0)

The point 4 units right of point J = (-4 + 4, 4) = (0, 4)  

The point 4 units left of point J = (-4, 4 - 4) = (-4, 0)

Therefore the points that are 4 units from point  J are (-4, 8), (-4, 0), (0, 4) and (-4, 0).

Answer:

Please find attached the required inverse of a function chart

Step-by-step explanation:

The inverse of a function is found by reversing the operations of the  function

The inverse of the function f(x) = 2·x - 4 is found as follows;

x = 2·x - 4

x + 4 = 2·x

x = (x + 4)/2 = x/2 + 2

Therefore, the inverse of the function f(x) = 2·x - 4 is f(x) = x/2 + 2

The inverse function is plotted by generating data points as follows;

{}x         {}          f(x)

0                2

1                  2.5

2                 3

3                  3.5

4                   4

5                   4.5

6                   5

7                   5.5

What is the value of f(-4) in the piecewise function f(x)= -x-5 for -5&lt;= x &lt;= -2; -x^2+1 for -2&lt;=x&lt;=2; (x-3)^2+2 for
Alik [6]


We first need to pick the correct piece to use. In this case, we will use f(x) = -x-5 because -5<=-4.

Then, we use direct substitution:
f(-4) = -(-4) - 5
f(-4) = -1
