For the graph to cross the x axis twice, b²-4ac needs to be larger than 0
b=-k, a=1, c=k²
b²-4ac=k²-4k²=-3k²
-3k² will never be larger than 0.

Answer:

K has no solutions.

Step-by-step explanation:

Because the parabola opens upwards and the y-intercept is non-negative, the parabola cannot cross the x-axis twice. Duh.

Find the value of x in the triangle shown below.<br> 13<br> 5<br> х
katen-ka-za [31]

Answer:

x=12

Step-by-step explanation:

This is a right triangle, so the Pythagorean theorem can be used. The Pythagorean theorem states that C^2=a^2+b^2 where C is the hypotenuse and a and b are legs. In this question, we are given a and C. So, plugin 13 for C and 5 for a and solve for b. Once you rearrange the equation you get, b=\sqrt{13^2-5^2}. Next, solve what is under the root to get, b=\sqrt{144}. Finally, square root 144 for the final answer b=12.

Q #5 please I need your help
mojhsa [17]

"Standard form" is the form ...

... ax +by = c

where a, b, c are mutually prime integers and the leading coefficient is positive. (If a ≠ 0, then it is "leading". If a = 0, then b is the leading coefficient.)

Of the choices offered, the only one that is equivalent to the given equation is ...

... -x + 6y = 5

_____

However, "standard form" requires the leading coefficient be positive, so an appropriate answer would be ...

... x -6y = -5

or

... 6y -x = 5

____

This is another one for my "broken question" file.

Vlada [557]

Answer:

For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.

Step-by-step explanation:

The sales price is not predicted to increase by $1.1; it is predicted to increase by $110,000 because S is measured in hundred-thousands of dollars. The sales price will not decrease by $110,000; it is predicted to increase by $110,000.
