Answer:
30
Step-by-step explanation:
let the length of VN be x
VNB ~ VMD
VN/VM = BN/DM
x/(30+x) = 12/24
24x=12(30+x)
24x=360+12x
12x=360
x = 30
Well you would have to fill in the bank so it would be 4000 and the answer would be 11,000 <span />
Answer:
x = 19
Step-by-step explanation:
you can set up a proportion among corresponding sides:
<u> 2x -14 </u> = <u> 18 </u>
32 24
18 /24 can be reduced to 3/4
<u> 2x - 14 </u> = <u> 3 </u>
32 4
cross-multiply: 4(2x - 14) = 32(3)
8x - 56 = 96
8x = 152
x = 19
-2x=10-6
The answer: x= -2
Y = x
when x < -1
not equal to (≤) so no solid circle.
plot points
x | y
-1, -1
-2, -2
-3, -3
Next one is...
y = -x
when x ≥ -1
solid circle for equal to
look at points
x | y
-1, 1
0, 0
1, -1
2, -2
As you can see it's the last graph in bottom right corner.
