Line 1 ——> y= 3/2x +1/2
Line 2 ——> y= -2/3x+4/3
Line 3 ——> y= -2/3x-7
therefore,
Line 1 & Line 2 : Perpendicular
Line 1 & Line 3 : Perpendicular
Line 2 & Line 3 : Parallel
hope this helped :)
Answer:
<h2>25p + 50q = 25(p + 2q)</h2>
Step-by-step explanation:
25p = (25)(p)
50q = (25)(2q)
therefore
25p + 50q = (25)(p) + (25)(2q) = (25)(p + 2q)
Answer to break even, cost = earnings= $455, number of miles to cover is 11
Step-by-step explanation: cost =422+3x, where x= number of miles covered
Earnings=400+5x
St break even, cost = earnings, then solving the linear equation, by collecting like terms, and dividing through by 22. x=11, the Pu x=11 in the either the cost or earnings expressing to get 455
