Answer:
hi, it is all the real numbers between -5 and +5
Answer:
Brass + Brass = Woodwind
Brass + Woodwind = 150
Brass = 50, Woodwind = 100
Step-by-step explanation:
Hi there!
The two addition equations would be:
Brass + Brass = Woodwind
(As there are twice as many woodwind as brass)
AND
Brass + Woodwind = 150
(As there are 150 of those instruments in total)
These two equations fully describe this situation, and you can use them to solve the problem using substitution as well.
Since Woodwind = Brass + Brass, then:
Brass + Woodwind =150
Can also be written as:
Brass + (Brass+Brass) = 150
Now we can solve by combining all the like terms which gives us:
3*Brass = 150
Brass = 150/3
Brass = 50 meaning that Woodwind = 100, as 50+50=100.
Hope this helped!

Answer:
a) y= x+7
The slope is 1 and the y intercept is 7
b) y = -3x
The slope is -3 and the y intercept is 0
Step-by-step explanation:
The slope intercept form of the equation of a line is
y = mx+b where m is the slope and b is the y intercept
a) y= x+7
The slope is 1 and the y intercept is 7
b) y = -3x
The slope is -3 and the y intercept is 0
