Hello there!

When finding the domain of a function, the only things you need to watch for are...
1. Variables under even radical signs
2. Variables in the dominator of fractions
3. Logarithms

Since this function is linear, there is nothing that would stop any real number from being part of the domain.

This means that the domain is all real numbers. (-∞,∞)

I hope this helps!
Best wishes:)

if trangle pqr is translated 4 units to the right to form triangle p'q'r' how are the values on the orderd pairs affected by the
Vesna [10]

Answer:

The x-coordinate of each point will increase by 4.

Step-by-step explanation:

So Triangle PQR is being translated 4 units to the <em>right</em>. Since we are going to the <em>right</em>, this is a shift on the x-coordinate.

And since we're going 4 units, every x-coordinate is going to be added by 4.

In other words, if we have:

A(x,y)

Then the new coordinate, A', is:

A(x,y)\rightarrow A' (x+4,y)

So, let's find the new coordinates of each point.

Point P is (-5,6). So:

P(-5,6)\rightarrow P'(-5+4,6)=P'(-1,6)

The new Point P is at (-1,6).

Point Q is at (2,6). So:

Q(2,6)\rightarrow Q'(2+4,6)=Q'(6,6)

The new Point Q would be at (6,6).

And Point R is at (-3,2). So:

R(-3,2)\rightarrow R(-3+4,2)=R(1,2)

The new Point R is at (1,2).

And we're done!

Which expression is equivalent to 30m2+12m+18?? Please help ASAP !
ANTONII [103]

Answer:

c) 6(5m2+2m+3)

Step-by-step explanation:

Given expression = 30m2 + 12m + 18

The simplified form can be calculated by taking GCF

The GCF of 30m2, 12m and 18 is = 6

Therefore, the expression becomes

(6*5m2 + 6*2m + 6*3)

=> 6(5m2+2m+3) so option c is correct
