Answer:
j = -10
Step-by-step explanation:
Given the mathematical expression;
-10 − 10j = -9j
To find the value of j?
Rearranging the equation, we have;
-10 = -9j + 10j
-10 = j
Therefore, j = -10
Step-by-step explanation:
By Intersecting Chords Theorem,
9 * 4x = 8 * (4x + 2).
=> 36x = 32x + 16
=> 4x = 16, x = 4. (2)
Sixty two million, one hundred thirty two thousand, two hundred seventy four
Answer:

Step-by-step explanation:
Let the numbers be x , y
Sum of two numers = -7
x + y = -7------------(I)
Two times the first number equals 4 the second number.
2x = 4y ----------(II)
Divide both sides by 2

x = 2y
Subtitute x = 2y in equation (I)
2y + y = -7
3y = -7
y = -7/3
Plugin y = -7/3 in equation (II)

Answer:
(-5,7)
Step-by-step explanation:
When we move from (-5, -8) to (-7, -6), we move -2 units across the x axis to get from the 1st to 2nd point, and we move -2 units across the y axis to get from the 1st to the 2nd point. So, just subtract -3 by 2 and 9 by 2 to get -5 and 7.
