Angle 3 and angle 4 form a linear pair. The measure of Angle 3 is four more than three
mel-nik [20]

Answer:

angle 3. ( x ) is 136°

angle 4 ( y ) is 44° !!

Step-by-step explanation:

Let angle 3 be x and angle 4 be y

Given, Angle 3 and angle 4 form a linear pair

x + y = 180 [ sum of linear pair angle is 180 ] ... ( i )

Also, The measure of Angle 3 is four more than three

The measure of Angle 3 is four more than threetimes the measure of angle 4.

x = 4 + 3y .... ( ii )

Putting value of x from ( ii ) in ( i )

4 + 3y + y = 180

4y = 176

y = 44

Also, x + y = 180 => x = 180 - 44 = 136

An online furniture store sells chairs for $200 each and tables for 166o ach. Every
ladessa [460]

Answer:

15 tables

Step-by-step explanation:

Chairs = $200

Tables = $600

Maximum items = 39

Minimum sales = $13,000

If 20 chairs are sold, revenue is $4,000. At least $9,000 in additional revenue is required. To earn $9,000, a minimum of 15 tables would need to be sold, which is fine since a maximum of 19 tables is permitted to be sold.

What is the equation for shifting the standard sine curve 2 units horizontally?
ratelena [41]
     Just add the displacement value to variable. If this value is positive, the graph will move to the right, otherwise it will shift to left.

f(\O)=sen(\O+x)
 
     Where: x=displacement value

If you notice any mistake in my English, please let me know, because I am not native.
