What extraneous solution arises when the equation √8x + 1 = 3x is solved for x

Mathematics
1 answer:
ryzh [129]2 years ago

The solution to the system of equation is -1/9 and 1

<h3>Rational expressions</h3>

Given the following rational expression

√8x + 1 = 3x

Square both sides to have:

(√8x + 1)² = (3x)²

8x + 1 = 9x²

Equate to zero

9x² - 8x - 1 = 0

Factorize

9x² - 9x + x - 1 = 0

9x(x - 1) + 1(x - 1) = 0
9x + 1 =0 and x - 1 = 0

x = -1/9 and 1

Hence the solution to the system of equation is -1/9 and 1

Answer:

x=5

Step-by-step explanation:

since two sides are congruent, the two unknown angles are congruent.

All triangle angles total 180 degrees.

so:

180-88=92

92/2=46

9x+1=46

9x=45

x=5

Which graph represents the function f(x) = |x + 3|?
DIA [1.3K]

Answer:

Graph of Modulus

The graph of a modulus or absolute value function is in a form of a 'V' shape whose vertex depends upon the coordinates. The equation for the graph is given as,

where,

(a, b) are the coordinates of the vertex of 'v' in the form of (x, y),

And h shows how wider or lean will be the function, for h=0, it is a straight line, while for a negative value the graph will face downwards and opposite for a positive value.

Given to us

y = |x-3|

On the coordinate plane

The graph will be in the shape of a 'V' whose vertex will lay at the coordinates (3, 0). As the value of a is 1 the graph will face upwards. As shown below on the graph.

Answer expression 1:<br><br> 6 x 7 - 3^2 x 9 + 4^3
skad [1K]

In order to get the answer to this question you will have to use PEMDAS and solve.

6\times7-3^2\times9+4^3

Using PEMDAS:

3^2=3\times3=9

4^3=4\times4\times4=64

6\times7-9\times9+64

6\times7=42

9\times9=81

42-81+64

81+64=145

42-145

42-145=-103

=-103

Therefore your answer is "-103."

Hope this helps.

What number completes the following equaton?<br><br>8x(40+7)=(8x )+(8x7)​
marishachu [46]

Answer:

Step-by-step explanation:

Well since the first expression says 8x(40+7) the answer would be 40 that is missing

Since your splitting 47 into 40 and 7 and multiplying both of them by 8 the answer would be 40
