286-42=144
144\2=122
122(peter)+164(malco)=286(total weight)
Answer:
<h2>
3y + 2 = 8</h2>
Step-by-step explanation:
solve A
2y - 3 = 19
2y = 22
y = 11
solve B
3y + 2 = 8
3y = 6
<h2>
y = 2</h2>
solve C
4y - 4 = -4
4y = 0
y = 0
solve D
5y + 1 = 10
5y = 9
y = 9/5
Step-by-step explanation:
explain step by step on photo, double check just in case
Domain is the x values you can use
range is the y values
a.
the domain
hmm, seems to be all real numbers except for at x=0, it gets really close tho
so D=(-∞,0)U(0,∞)
range is all real numbers except for y=0, it gets really close tho
R=(-∞,0)U(0,∞)
b.
domain
that empty circle means something like < or >
goes from 5 to 6, not including 5
so domain is D=(5,6]
range is from -4 to 2, not including -4
range is R=(-4,2]
Step-by-step explanation:
3(4x)=12x
Hope it helps?!
