Answer:
xy = 28
Step-by-step explanation:
The formula for inverse variation is
xy =k
If y = 4 and x = 7
4*7 = k
28 = k
The equation is xy = 28
Answer:
the measure of AB equals the measure of BC
2x+1=3x-4
4+1=3x-2x
5=x
BC=3x-4=3*5-4=15-4=11
AB=2x+1=2*5+1=10+1=11
AC=AB+BC=11+11=22
Step-by-step explanation:
Answer: 23
Step-step by explanation:
w(w+4)=437
w^2+4w-437=0
(w+23)(w-19)=0
w=19,-23
w<19
l<23!!
Answer:
B
