The two angles are identical:
3x -7 = 2x + 7
Add 7 to both sides:
3x = 2x + 14
Subtract 2x from both sides:
X = 14
Based on the data set shown, which of the following is a true statement? -1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
babymother [125]
<span>-1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3
Median=1
</span><span>Mean=(-1+-1+0+1+1+1+1+2+2+2+3)/11=11/11=1
Mode=1
So the first option is true
Answer: mean=mode</span>
Z = -b - a + 1
subtract 1
1z - 1 = -1b - 1a ( 1z is the same as z, same goes for b and a)
add -1b
1b - 1z - 1 = -1a
then we remove -1 by dividing it.
-1b -(-1z) + 1
Answer: -1b -(-1z) + 1 = A
A negative minus a negative is a positive, so the answer might as well be....
-1b + 1z + 1 = A
5x/7 - 5 = 50 is 4. x = 77
#7 is the easiest one.
a + bi = -9 + 4i
see the expression on either side matches up so..
a = -9 and b = 4
