If log10 y = 2. what does y equal?

Answer:

$log_{10} (100) = 2$

Step-by-step explanation:

Here, the given expression is:

$log_{10} (y) = 2$

Now, by logarithm rules, we know

if $log_{b}(x) = z$

, then x = $b^{z}$

Comparing here, b = 10 and z = 2

⇒ y = $10^{2} = 100$

or, $log_{10} (100) = 2$

Answer:

C is correct

Step-by-step explanation:

Given: System of linear inequality

$y$

$y\geq 2x+3$

First we will draw the graph of system of equation and then see the correct option.

Equation 1: $y$

We will make the table.

x : -2 0 2

y : 1 0 -1

Test Point: (0,4)

0<-2 ( False )

Shaded area away from (0,4)

Equation 2: $y\geq 2x+3$

We will make the table.

x : -2 0 2

y : -1 3 7

Test Point: (0,4)

4≥3 ( True )

Shaded area towards (0,4)

Please see attachment for graph.

Hence, C is common shaded area (region)
