Answer:
<h2>NOT</h2>
Step-by-step explanation:
Put x = 1, y = -1 and z = -2 to the equation 3x - 3y - z = 2, and check the equality:
3(1) - 3(-1) - (-2) = 3 + 3 + 2 = 8 ≠ 2
Answer:
6 different groups.
Step-by-step explanation:
This is the number of combinations of 2 fro m 4:
4C2 = 4! / 2! 2!
= 4 * 3 *2 *1 / (2*1*2*1
= 24/4
= 6 groups.
Let’s call the number “n.” 0,32n=64 (32% is 32 per cent-, or per hundred), and n=64*100/32=100*2=200. Therefore, the answer’s D.
Answer:
IJ = 34
Step-by-step explanation:
Since HK = JK, then IK is a perpendicular bisector and Δ is isosceles, then
IJ = HI , that is
2s = s + 17 ( subtract s from both sides )
s = 17
Then
IJ = 2s = 2 × 17 = 34
7/28 = 25/x
x = (25 × 28)/7
x = (25 × 4)
x = 100
