Answer:
90 degree angle because a right angle is always 90 degrees
Answer:
16
Step-by-step explanation:
If n is number of nickles and d is number of dimes:
5n + 10d = 440
n = 3.5d
Substitute:
5(3.5)d + 10d = 440
17.5d + 10d = 440
27.5d = 440
d = 16
If i= V-1, then -117 expression is equal to 9i(13i)
Step-by-step explanation:
Original problem : 9i(13i)
=> 117 (Multiply)
=> 117 * -1
=> = -1
=> -117
If i= V-1, then -117 expression is equal to 9i(13i)
Answer:
idk what you mean by thorough explanation but:
- get two points of the line (x1, y1) and (x2, y2)
- plug them into the formula: y2 - y1/x2 - x1
- solve
Answer: x > 6, x < -8
Subtract 4 from both sides.
−3∣x+1∣<−17−4
Then simplify -17 - 4 to -21.
−3∣x+1∣<−21
Divide both sides by −3.
|x + 1| > -21/-3
Two negatives make a positive.
|x + 1| > 21/3
simplify 21/3 to 7
Break down the problem into these 2 equations.
x + 1 > 7
-(x + 1) > 7
Solve the 1st equation: x + 1 > 7
x > 6
Solve the 2nd equation: -(x + 1) > 7
x < -8
last collect all solutions
x > 6, x < -8
