3x - 2y = 7
-2y = -3x + 7
y = 3/2x - 7/2....slope of this line is 3/2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -2/3 (see how I flipped the slope and changed the sign)
y = mx + b
slope(m) = -2/3
(-3,-2).....x = -3 and y = -2
now we sub and find b, the y int
-2 = -2/3(-3) = b
-2 = 2 + b
-2 - 2 = b
-4 = b
so ur perpendicular equation is : y = -2/3x - 4 <==
You'll see how to set up a table, choose appropriate x-values, plug those values into the equation.
Answer:
A) I) 49 teams
II)63 teams
B) 28 teams
Step-by-step explanation:
A) a team of 5 boys and 6 Girls
=7C5+ 8C6
= 21+28
= 49 teams
a team of 6 boys and 5 girls
= 7C6 + 8C5
= 7+56
= 63 teams
B) one girl is kept constant already and a guy has injury
Girls remaining to choose from 7
Boys remaining to choose from 6
= 1 +7C5 + 6C5
= 1+21+6
= 28 teams
Answer:
{-5,-4,2,4}
Step-by-step explanation:
the domain is which x-values are included so use each of the x-values for each pair. Make sure if there are reapeats that you only write them once.
Answer:
The correct option is b.
Step-by-step explanation:
To find the number of solutions, we need to solve the equation:
Let's group all the "x" on the equation.
Now, let's solve for "x".
Therefore, the equation has one solution. The correct option is b.
I hope it helps you!
