How many solutions does the equation 3x + 6 = − 1 − 3 + 4x have?Two
Zero
One
Infinitely many

Answers

Answer 1
Answer:

Answer:

The number of solutions of the equation is:

                                    One.

Step-by-step explanation:

We are asked to find the number of solutions of the equation:

3x+6= -1-3+4x

(

We know that a expression has a unique or one solution if it gives a single value of x after solving the expression.

and we obtain a no solution when the equation gives a false result i.e. the left and right hand side of equality are different.

and infinite many solution if the left and right hand side of equality is same but we can't get a fix value of x )

Now on solving the expression we have:

                     3x+6= -4+4x

i.e.                 4x-3x=6+4

i.e.                      x=10  

Hence, we get a unique value of x.

Hence, the equation has one solution.
Answer 2
Answer: it has One solution and to get it solve the equation for x :
6+1+3=4x-3x
x=10

What multiplies to -160 and adds to 6

Answers

Hello,
These 3 numbers have a product of -160 and a sum of 6

8,-1+√21 and -1-√21.
The answer: -10×16=-160, -10+16=6, so the numbers are (-10,16).

Given log 2 = 0.3010, log 3 = 0.4771. Find the value of a) log 12 b) log 5.

Answers

a) log 12 
= log3*4
= log3 + log4
=log3 + log 2^2
=log3 + 2log2
= 0.4771 +2*0.3010
=1.0791

b) log5
= log10/2
= log10 - log2
=1 - 0.3110
= 0.6989
a)\ \ \ log12=log(4\cdot3)=log4+log3=log2^2+log3=2log2+log3\approx\n\n\approx2\cdot0.3010+0.4771=0.602+0.4771=1.0791\n\n2)\ \ \ log5=log (10)/(2) =log10-log2\approx1-0.3010=0.699

How do you do this problem?You have $22 and you use it four tickets and after you bought it, you have $6 left. How much did each ticket cost?

Answers

Answer: $4.

Explanation: Get $22 nd minus $6 you have left, and it equals $16 for the total of tickets. Then get $16 and divide it with the number of tickets, which is 4, so $4 for 1 ticket!

Hope this helps!

Is 5 - (-3) equal to 8 or -2. And if one or the other, please state why one is correct and the other isn't.

Answers

8

two negatives make a postive as they cancel each other out

5 - - 3 = 5 + 3 = 8

the only way the answer could be - 2 is if the original question said 5 + - 3 = - 2
