Answer:
71 & 25 m
Step-by-step explanation:
a • b = 1775
2a + 2b = 192
substitution:
a = 1775/b
2(1775/b) + 2b = 192
distribute the 2
(3550/b) + 2b = 192
subtract 192 from both sides
(3550/b) + 2b - 192 = 0
transform the expression by dividing all terms by b
(3550 + 2b² - 192b) / b = 0
when the quotient of expressions equals 0, the numerator has to be 0
3550 + 2b² - 192b = 0
reorder the terms
2b² - 192 b + 3550 = 0
divide by sides by 2
b² - 96b + 1775 = 0
rewrite -96b as a difference using factoring X
b² - 25b - 71b + 1775 = 0
factor the expression (factor out b)
b (b-25) - 71b + 1775
factor out b - 25 from the expression
(b - 25) (b - 71) = 0
if b = 25 or 71, then a = 71 or 25
71 & 25 m
It is the negative reciprocal to the slope of the line it is perpendicular to. For example, if the slope of that line was 3, the negative reciprocal would be -1/3, because if you multiplied them, -1/3 × 3/1, you'd get 3/3 which is 1. If the slope given was -4, the negative reciprocal would be 1/4, the negative reciprocal given of 1/2 would be -2, etc. I hope this helps! Let me know f I've just confused you :)
Answer:
1. about 11.18
2. about 8.66
Step-by-step explanation:
1. 5^2 + 10^2= 125
square root of 125 equals about 11.18
2. 10^2-5^2=75
square root of 75 equals about 8.66
Answer:
1: One Solution
2: Infinite Solutions
3: No Solutions
Step-by-step explanation:
1: Two lines meet only once
2: The lines are on top of each other
3: They are parallel and will never meet (like the love of my life)
