Answer:

She used 87 minutes last month

Step-by-step explanation:

Step 1: Express the total monthly phone bill

The total monthly phone bill can be expressed as follows;

A=F+(R×M)

where;

A=total monthly phone bill

F=fixed income per month

R=additional rate per minute

M=total number of minutes

In our case;

A=$123.75

F=$102 per month

R=$0.25 per minute

M=m

replacing;

123.75=102+(0.25 of m)

123.75=102+(0.25×m)

123.75=102+0.25 m

123.75-102=0.25 m

0.25 m=21.75

m=21.75/0.25

m=87 minutes

She used 87 minutes last month

Find the area of the triangle defined by the coordinates (7, 1), (0, 10), and (9, 4). (To the nearest tenth)
slega [8]

Answer:

  C)  19.5 square units

Step-by-step explanation:

The area from coordinates can be computed as ...

  A = (1/2)|x1(y2 -y3) +x2(y3 -y1) +x3(y1 -y2)|

  = (1/2)|7(10 -4) +0(4 -1) +9(1-10)| = (1/2)|7·6 +9·(-9)|

  = (1/2)|-39| = 39/2 = 19.5

The area of the triangle is 19.5 square units.

Can someone help me understand the concept of finding the domain and range on a graph. I don’t understand it! Someone help me
juin [17]

Answer:

The Domain is where the line on your graph crosses the X axis.

The Range us where the line on your graph crosses the Y axis

And a arrow means it goes Into infinity

Step-by-step explanation:

Say you Have a line, it crosses the X axis at -3, your Domain would be -3!

Now say this line crosses the Y axis at -6, Your Range would be -6!

And now say if instead of the line ending at a dot after crossing -6 It has a arrow, that means you have infinity, Making your range instead of -6 it's be infinity! (If the arrow points up it's positive infinity, If the arrow points down it's negative infinity)

So for the first 2 numbers your answer would be [-3,-6] and in you have infinity itd be [-3, infinity) parenthesis isn't a error btw if you still don't get it I can just reply with a sheet I have on it
