A.
2/3A=-24
time both sides by 3/2
A=-72/2
A=-36

B.
20=-B/0.2
times both sides by 0.2
4=-B
times -1
-4=B

distance between 2 points x and y is |x-y|

so
distance between A and B is distance between -4 and -72 or
|-72-(-4)|=|-72+4|=|-68|=68
the distance is 68

Answer:

Step-by-step explanation:

f(x) = 3x + 1 and g(x) = x^2 - 6

(f + g) (x)

(3x + 1) + (x^2 - 6)

3x + 1 + x^2 - 6

3x - 5 - x^2

=> -x^2 + 3x - 5

I hope this helps!

There are a total of 21 students in the choir and the drama club. There are 7 more students in the choir than the drama club. Wr

PolarNik [594]

Answer:

The number of students in the drama club is 7 and the number in the choir is 14

Step-by-step explanation:

X = Number of students in choir club

Y = Number of students in drama club

First equation:

x + y = 21

Since we know that there are 7 more students in the choir club than the drama club, that means:

x + 7 = y

A little trick that you can do to find y is this:

21 students in the choir and drama club - 7

=> 14

Meaning that y is 14

So lets go back into our second equation:

x + 7 = 14

7 + 7 =14

x=7

Plug both variables in:

7 + 14 = 21

So that means that there are 7 students in the drama club and 14 students in the choir club.
