Y=log x If y=10, then what is x?
netineya [11]

Answer:

First question, x= 10^10.

Second question is 10!. or 362880

Step-by-step explanation:

First Question:

Simple logx has a base of 10, i.e log10 x,

the question will be 10 = log10 x,

when taking the base "10" from the right side to the left, the number on the left side becomes the power of the base, in this case 10 from the right will be base and 10 from the left will power and log will vanish.

x=10^10.

Another example with different numbers

Y=logx if Y= 12, What is x?

The base is ten when not given,so:

12=logx

10^12=x

Second Question;

simple multiplication just multiply the numbers.

10! is pronounced as 10 factorial,

5! will be 5x4x3x2x1=120

Y = x + 2<br> y = 3x - 4
exis [7]

Answer:

x=3; y=5

Step-by-step explanation:

y=x+2

y=3x-4

so x+2=3x-4

2x=6

x=3

because y=x+2

                  x=3

so y=3+2

     =5

What is the solution to the system of equation<br> -7x-2y=-13<br> X-2y=11<br> Using substitution
Gnom [1K]
        -7x - 2y = -13
-7x + 7x - 2y = 7x - 13
               -2y = 7x - 13
                -2         -2
                 y = -3.5x + 6.5

                      x - 2y = 11
    x - 2(-3.5x + 6.5) = 11
x - 2(-3.5x) - 2(6.5) = 11
             x + 7x - 13 = 11
                   8x - 13 = 11
                       + 13 + 13
                          8x = 24
                           8      8
                            x = 3

y = -3.5x + 6.5
y = -3.5(3) + 6.5
y = -10.5 + 6.5
y = -4
(x, y) = (3, -4)
