Answer:
y = 1.00+0.10 x (if this is what you meant)
Step-by-step explanation:
Given that a taxi has a minimum charge of 1 dollar upto 1/10 mile and adds 0.10 for every additional 1/10 mile.
If a person travels <=1/10 miles his charges are 1 dollar
If he travels >1/10 miles charges are 1 dollar +0.10(extra miles 1/10)
Let y be the charges and x be the no of 1/10 miles.
Then the equation for y in terms of x would be
y =1.00 +1/10(x)
y = 1.00+0.10 x
Answer:
Step-by-step explanation:
Given :
l + m + n = 9
l²+ m² + n²= 31
l + m + n = 9
On squaring both sides
(l + m + n)²= 9²
(l²+m²+n²+2(lm+mn+nl) = 81
31 +2(lm+mn+nl) = 81
2(lm+mn+nl) = 81 - 31
2(lm+mn+nl) = 50
(lm+mn+nl) = 50/2
(lm+mn+nl) = 25
Hence, the value of (lm+mn+nl) = 25
