Answer:
3x + y = -1
Step-by-step explanation:
y-5=-3( x+2)
once you distribute, you get y-5=-3x-6
then, add 5 to each side and get y=-3x-1 (this is slope intercept form)
finally, add 3x to each side to get 3x+y=-1 (standard form: Ax + By = C)
Answer:Its A
Step-by-step explanation:Collinear points are the points that lie on the same straight line or in a single line. If two or more than two points lie on a line close to or far from each other, then they are said to be collinear, in Euclidean geometry. ( this is from g.o.o.g.l.e but i put my sense into this question and a is the only one that makes sense )
Yes because none of them share the same X value
Answer:
40 girls
Step-by-step explanation:
Set up a proportion where x is the number of girls in band class:
= 
Cross multiply and solve for x:
3x = 120
x = 40
So, there were 40 girls in band class.
