Write an equation that would have the restriction x ≠ -3.

Mathematics
1 answer:
Sunny_sXe [5.5K]3 years ago
8 0

Answer:

Here, the condition is x ≠ -3

Therefore, we'll compute an equation under which x being 3 will not possible in order to evaluate the equation.

One of such equation is :

y = \frac{x - 3}{x + 3}  

With the condition that x ≠ -3, because then the denominator will become ∞ and hence we won't be able to evaluate the equation.

Solve 3 x - 9 x + 7 - 3 = -8.
erik [133]

Answer: x=2

3x−9x+7−3=−8

Step 1: Simplify both sides of the equation.

3x−9x+7−3=−8

3x+−9x+7+−3=−8

(3x+−9x)+(7+−3)=−8

−6x+4=−8

−6x+4=−8

−6x+4−4=−8−4

−6x=−12

−6x

−6

=

−12

−6

Rewrite 4 1/2=2 <br> please
Luda [366]

The logarithmic expression of 4^(1/2) = 2 is \log_4(2) = \frac 12

<h3>How to rewrite the expression?</h3>

The expression is given as:

4^(1/2) = 2

Take the logarithm of both sides

log(4^(1/2)) = log(2)

Apply the change of base rule

1/2log(4) = log(2)

Divide both sides by log(4)

1/2 = log(2)/log(4)

Change the base

\frac 12 =\log_4(2)

Rewrite as:

\log_4(2) = \frac 12

Hence, the logarithmic expression of 4^(1/2) = 2 is \log_4(2) = \frac 12

Find the surface area of the following Cube. <br> 4in<br> 4in<br> 4in
Assoli18 [71]

Answer:

In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.

Find a three digit number. The tens digit is 3 time the hundreds digit. The sum of the digits is 15. If you reverse the digits,
tresset_1 [31]

Answer:

number = 267

Step-by-step explanation:

i am a 3 digit number divisible by 3.

100a + 10b + c

my tens digit is 3 times as great as my hundreds digit

b = 3a, from this we know a = 1, 2, 3, then b = 3, 6, 9

and the sum of my digits is 15.

a + b + c = 15

if you reverse my digits i am divisible by 6 and 3

100c + 10b + a

this is a logic problem, an equation won't help us here

From the given information b = 3a, and the sum of the 3 digits = 15, we have:

1 3 ___; three single digits can't add up to 15

2 6 _7_; this has to be the number

3 9 _3_; reverse number is not different

Check for division by 3 and 6

267/3 = 89

762/6 = 127

267 is the number
