What values are not in the domain of (-5+2x^2)/7-8x ?

Mathematics
1 answer:
NemiM [27]3 years ago
4 0

\frac{-5 + 2x^{2}}{7 - 8x}

The denominator cannot equal zero.

7 - 8x ≠ 0

7       ≠  8x

    \frac{7}{8} \neq \frac{8x}{8}

\frac{7}{8} \neq x

Answer: \frac{7}{8} is not in the domain

Which graph correctly represents (5/2)x - y < 3?
Setler79 [48]

You can rewrite the inequality as

y > \cfrac{5}{2}\ x - 3

Note that

y = f(x) = \cfrac{5}{2}\ x - 3

is the equation of the line drawn in the pictures. This means that, for every point on the line, the y coordinate is exactly image of the x coordinate, i.e. f(x)

The inequality is satisfied by all points whose y coordinate exceeds the image of the x coordinate. Since the y axis is positively oriented upwards, a greater value for the y coordinate means that the point has to be higher than the line.

Also, since the equality inlves a > and not a \geq sign, the line itself is excluded.

So, the correct graph is the second one.

What is the difference of the two expressions?
valkas [14]

<em>Answer is x + 12</em>

<em />

<h2>Explanation:</h2>

Hello! Recall that you have to write clear questions in order to get exact answers. So I'll help you assuming that the two expressions are the following:

First expression:

2x+9

Second expression:

x-3

So the operation we need to perform is:

2x+9-(x-3)

Recall some rules:

(+)\times (+)=+ \\ \\ (-)\times (-)=+ \\ \\ (-)\times (+)=- \\ \\ (+)\times (-)=-

Hence:

2x+9-(x-3)=2x+9-x+3 \\ \\ \\ Combine \ like \ terms: \\ \\ (2x-x)+(9+3) \\ \\ \boxed{x+12}

Graph the inequality in the coordinate plane. x&lt;-6
puteri [66]

Answer:

You would make a dotted vertical line running through -6 on the horizontal or x axis. The shading would go to the left side of the line since x is less than -6 and the line is dotted because it is only less than and not equal to.

Step-by-step explanation:
