Masja [62]3 years ago

The ordered pair (-1, 6) is the solution to the system of equations.

Step-by-step explanation:

Given equations are;

3x+2y=9     Eqn 1

y=4x+10    Eqn 2

Putting value of y from Eqn 2 in Eqn 1

3x+2(4x+10)=9\\3x+8x+20=9\\11x=9-20\\11x=-11

Dividing both sides by 11

\frac{11x}{11}=\frac{-11}{11}\\x=-1

Putting x=-1 in Eqn 2

y=4(-1)+10\\y=-4+10\\y=6

Solution: (-1, 6)

The ordered pair (-1, 6) is the solution to the system of equations.

5 < 4x = 2> 3x PLEASE HELP
Galina-37 [17]
Looks fishy to me, the way this problem combines <, = and > symbols.

But anyway.  Subtract 3x from both sides.  You'll get

5 < x = 2 > 0      2 > 0 is true, but that's a different type of math problem (true or false).    If you decide to substitute '1' for 2 > 0, then the "1" says "TRUE."

Then 5 < x = true, so you must find x values that are larger than 5.

That would be (5, infinity)

Please go back and ensure that you have copied down the original problem exactly as it appears.

A teacher selects students from her class of 37 students to do 4 different jobs in the classroom: pick up homework, hand out per
dolphi86 [110]

Answer:

66045 ways

Step-by-step explanation: There are actually total of 37 student, and total of 4 jobs. But if the jobs are to be done by only one person each, then we are selecting 4 students.

So the number of ways of selecting 4 out of 37 using combination is

=37C4

=37!/(37-4)!(4!)

=37!/33!4!

=66045
