Hello,

Answer B

3x-4y=7==\ \textgreater \ y= \frac{3}{4} *x- \frac{7}{4} ==\ \textgreater \ slope=\frac{3}{4}\\\\

y+2=\dfrac{3}{4}*(x+4)==\ \textgreater \ 4y+8=3x+12==\ \textgreater \ 3x-4y=-4


is the only solution.

3x - 4y = 7
-4y = -3x + 7
y = 3/4x - 7/4.....the slope here is 3/4. A parallel line will have the same slope.

y - y1 = m(x - x1)
slope(m) = 3/4
(-4,-2)....x1 = -4 and y1 = -2
now we sub
y - (-2) = 3/4(x - (-4) =
y + 2 = 3/4(x + 4) <=== this is one

y + 2 = 3/4(x + 4)
y + 2 = 3/4x + 3
y = 3/4x + 3 - 2
y = 3/4x + 1
-3/4x + y = 1
3x - 4y = -4 <==== this is one

The table gives the probabilities that new cars of different models will have brake failure. The car model that is least likely
melamori03 [73]
<span>All the information we have are the probabilities, and what we need is the lowest number: so let's choose the smallest probability among the numbers: 0.0065%, B 0.0037%,C 0.0108%,D 0.0029%, E 0.0145%. The smallest of the numbers is 0.0029% -it starts with two 00s and the number that follows, 2, is smaller than all there others - so the smallest probability is in option D - and the model would be the corresponding model (but we're missing some information here) </span>

barxatty [35]
So in a 8 hour workday he would make $72... 9x8=72
now 155-72= 83 
83/6= a little over 13
so he would at least have to make 14 deliveries
