Answer:
n(B') = 15
Step-by-step explanation:
Assumunin U is the universal set.
B = { 7,11,17,19}
B' = natural numbers different form 7,11,17 and 19 = {1,2,3,4,5,6,8,9,10,12,13,14,15,16,18}
Let x be the first
the second x +2
the third x+ 4
<span>twice the smallest 2x
</span><span>three times the largest 3(x+4 )
</span>2x + <span>3(x+4 )=42
</span>
2x +3x +12 = 42
5x= 30
x=6 the second is 8 the third is 10
Answer:
You need to plot the points at (1.5, 0) and (0,-3)
Step-by-step explanation:
Y=3/5x+4
this can be solved using y=mx+b where m = slope and b = y intercept
Y = -4x +5 should be right!
