Which graph represents the solutions of the inequality p ≥ -1

soldi70 [24.7K]

Option D:

The solution of the inequality p is –1, 0, 1, 2, 3, ...

Solution:

Given inequality is p ≥ –1.

To find the solution for the inequality.

p ≥ –1 means the value of p is greater than or equal to –1.

That is p can be –1, 0, 1, 2, 3, ...

<u>Now find which option is correct:</u>

Option A:

In this inequality, the solution is –1, –2, –3, ...

–3 and –2 are less than –1.

But p is greater than –1.

So, it is not the solution of the inequality.

Option B:

In this inequality, the solution is 0, 1, –1, –2, –3, ...

Here 0 > –1 and 1 > –1 but –3 and –2 are less than –1.

So, it is not the solution of the inequality.

Option C:

In this inequality, the solution is 0, 1, 2, 3, ...

Here 1 > –1 , 2 > –1 and so on.

But 0 is also greater than –1. This is missing in the graph.

So, it is not the solution of the inequality.

Option D:

In this inequality, the solution is –1, 0, 1, 2, 3, ...

Here –1 = –1, 0 > –1, 1 > –1, and so on.

This graph represents all the values of p.

So, it is the solution of the inequality.

Hence option D is the correct answer.

The solution of the inequality p is –1, 0, 1, 2, 3, ...

Find the equality represented by the graph?

Talja [164]

Answer:

$-x+4y$

Step-by-step explanation:

Given: graph

To find:the inequality

Solution:

Equation of a line passing through points $(x_1,y_1),(x_2,y_2)$ is given by $y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Take $(x_1,y_1)=(0,3),(x_2,y_2)=(4,4)$

So,equation of line is evaluated as follows:

$y-3=\frac{4-3}{4-0}(x-0)\\ y-3=\frac{x}{4}\\ 4y-12=x\\-x+4y=12$

As per the graph,inequality is $-x+4y$

Here, use sign < and not $\leq$ as line in the graph is dotted that is points on the line are excluded.

Which equation is the inverse of 5 y + 4 = (x + 3) squared + one-half?

telo118 [61]

Answer:

The correct option is the last option d.) y = negative 3 plus-or-minus StartRoot 5 x + seven-halves EndRoot

Step-by-step explanation:

the given equation is $5y + 4 =(x+3)^{2} + \frac{1}{2}$

Therefore we can write $5y\hspace{0.1cm} = (x+3)^{2} + \frac{1}{2} - 4 \hspace{0.3cm} \Rightarrow \hspace{0.2cm} 5y = (x+3)^{2} - \frac{7}{2} \hspace{0.3cm} \Rightarrow \hspace{0.3cm} y = \frac{(x+3)^{2}}{5} - \frac{7}{10}$

To find the inverse of the above function let us replace x with y and y with x.

Therefore we get

$x = \frac{(y+3)^{2}}{5} - \frac{7}{10}$

Now we write the above equation with only y on the Left hand side and we will obtain the inverse of the given function

$y = \pm \sqrt{5 (x + \frac{7}{10} )} \hspace{0.1cm} - \hspace{0.1cm} 3 \hspace{0.1cm} \Rightarrow\hspace{0.1cm} y = \pm \sqrt{5x + \frac{7}{2} } - \hspace{0.1cm} 3 \hspace{0.1cm}$

Therefore the correct option is the last option d.) y = negative 3 plus-or-minus StartRoot 5 x + seven-halves EndRoot , $y = \pm \sqrt{5x + \frac{7}{2} } - \hspace{0.1cm} 3 \hspace{0.1cm}$
