Determine the values of k for which the equation has no solution

Mathematics
1 answer:
Naddik [55]3 years ago
5 0

To solve this, we would need to figure out the values of k for which an absolute value is negative. From basics, you should know that an absolute value is always greater than or equal to 0.

If we rearrange this equation a little bit, we get,

|2x+7|\leq 5+k

So 5+k <em>cannot </em>be negative. So,

5+k\geq 0\\k\geq -5

For this to <em>have </em>a solution, k needs to be greater than or equal to -5.

For <em>no solution</em>, k is less than -5. So, values of k which will make the equation to <em>not </em>have any solution is k.

ANSWER:  k

siniylev [52]

Answer:

y = -2x

Step-by-step explanation:

It passes through -5, 10 and 5, -10

gradient = Δy/Δx

gradient = -10 - 10 / 5 -- 5

gradient = -20 / 10

gradient = -2

let's use -5, 10 for y = mx + b

10 = -2(-5) + b

10 = 10 + b

b = 10 - 10

b = 0.

the equation of the line is just y = -2x
