For the second one it is accurately 3
Why? Because the equation y=mx+b m is the slope. In this example they only give you the slope. You can also think of it as rise / run. Rise is the top number in a fraction or slope so that makes it positive because your going up.
Hope this makes sense and helps.

352.83 in expanded notation
8_murik_8 [283]

We can extend 352.83 and write as  (3 x 100) + (5 x 10) + (2 x 1) + (8/10) + (3/100)

Step-by-step explanation:

Considering the given value 352.83 we can expand that step by step as,

(3 x 100) which will give us a value of 300.

Now adding the multiplied answer of (5 x 10) will give us 350.

Next we can also add the multiplied answer of (2 x 1 ) which will further give us 352.

Now adding the divided answer of (8/10) we will get 352.08

Finally adding the divided answer of (3/100) we will get the exact value of 352.83 as mentioned above.

Draw the graph of the line that is perpendicular to Y= 4X +1 and goes through the point (2, 3)
spayn [35]

Given:

\begin{gathered} y=4x+1 \\ \text{ point }(2,3) \end{gathered}

To find:

Draw a graph of a line that is perpendicular to the given line and passing through a given point.

Explanation:

As we know that relation between two slopes of perpendicular slopes of lines:

m_1.m_2=-1

Slope of given line y = 4x + 1 is:

m_2=4

So, the slope of line perpendicular to given line is:

m_2=-\frac{1}{4}

Also, so line equation that is perpendicular to given line is:

y=-\frac{1}{4}x+c...........(i)

Also, the required line is passing thorugh given point (2, 3), i.e.,

\begin{gathered} 3=-\frac{1}{4}(2)+c \\ c=3+\frac{1}{2} \\ c=\frac{7}{2} \end{gathered}

So, line equation that is perpendicular to given line is:

y=-\frac{1}{4}x+\frac{7}{2}

The required graph of line is:

Let R be a ring with identity and let S be a subring of R containing the identity. Prove that if m is a unit in S then u is a un
kumpel [21]

Explanation:

Since m is a unit in S, then, there exists b ∈ S such that m*b = 1, where 1 is the identity. Since S is a subring of R we have that m ∈ R, and therefore b is also the multiplicative inverse of m in R. The converse isnt true.

The set of real numbers is a Ring with the standard sum and multiplication. Every real number different from 0 has a multiplicative inverse. For example, the inverse of 2 is 1/2. However, 2 is not a unit on the subring of Integers Z.
