How are discontinuities and zeros created in rational expressions

Marina86 [1]

I suppose that would just be when the numerator of the rational expression equals zero. Nothing special goes on with the graph in that case; there are simply x-intercepts at those values of x.

<span>Discontinuities are created when the denominator of the rational expression equals zero (because division by zero is undefined). Graphically, this is usually represented by a dashed vertical line indicating a vertical asymptote. </span>

A line has a slope of 1 and passes through the point (7,5). What is its equation in

GrogVix [38]

Answer:

$y=x-2$

Step-by-step explanation:

Slope-intercept form is $y=mx+b$ , so if $m=1$ , then we have $y=x+b$ and we'll need to plug in $(7,5)$ to get $b$ , the y-intercept:

$y=x+b$

$5=7+b$

$-2=b$

Therefore, the final equation in slope-intercept form is $y=x-2$

❖ A number y increased by 5 is at least -21.

$\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}$

❖ First, if you come across the word "increased" it means we

"increase" a number, or add something to that number, like

y increased by 5 $\longmapsto$ $\sf{y+5}$

Now, we are also given that this expression is at least -21, which means it can't be -21; it can be -21 or it can be greater than -21.

So we have

$\longmapsto\sf{y+5\geq -21}}$

<em>Solving for y</em>

<em></em>

Subtract 5 on both sides:-

$\longmapsto\sf{y\geq -21-5}$

$\longmapsto\sf{y\geq -26}$

So the values of y greater than or equal to -26 will make this inequality true.
