George tells you that when variables are in the denominator, the equation becomes unsolvable. "There is a value for x that makes
lyudmila [28]
The equation can still be solved but it should be stated clearly at what value of would the equation be undefined. For instance, you have an expression,

1/x+2

When x is equal to -2, the denominator will be 0 resulting to an undefined solution. The value of x here can be any real number except -2.

Determine the values of k for which the equation has no solution
Naddik [55]

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

How would I graph this?
elena55 [62]

y\leq 2x-5

↝ x-intercept

2x-5=0\\2x=5\\x=\frac{5}{2}

↝ y-intercept

y = -5

↝ y\leq 2x-5 means that the shade/area is below the graph as shown in the first picture.

y\leq -\frac{1}{2}x-3

↝ x-intercept

-\frac{1}{2}x-3=0\\-x-6=0\\-x=6\\x=-6

↝ y-intercept

y = -3

↝ Since it's "≤" therefore. The shade/area is below the graph. For second picture.

First picture is first inequality

Second picture is second inequality.
