Answer:
7 i think if wrong im so sorry
Step-by-step explanation:
Parallel lines have equal slopes. so the equation y=-4x+5.has slope of -4 because this is in slope intercept form y=mx+b where m is slope.
so we know a parallel line will have slope -4
we have a point on the line so we will use point slope formula to solve.
y-y1=m(x-x1) where (x1,y1) is point on line
so we get
y-4=-4(x-0) to put in slope intercept form we solve for y
y-4=-4x
y=-4x+4 is an equation of a line parallel to y=-4+5 passing through (0,4)
Its a recurring decimal that does not terminate
1/3 = 0.3333333.......
Divide both sides by 2
|x-3|>4 and |x-3|<-4
ok so |x-3|<-4 is false, since |x|≥0 always
so we have
|x-3|>4
now assume
x-3>4 and
x-3<-4
x-3>
add 3
x>7
x-3<-4
add 3
x<-1
so
-1>x and x>7
so basically it is all numbers from -∞ to +∞ except from -1 to 7
in interval notaion
(-∞,-1)U(7,∞)
S={x|x<-1 or x>7}
So, 14 out of 30 of the members are boys. There are 14 boys in chorus. 16 girls.
The ratio would be:
Now, divide both sides by two to simplify.
14/2= 7
16/2= 8
7:8
"A" 7/8, 7:8 is the <em>answer
</em>I hope this helps!
