rationalise the denominator by multiplying both top and bottom by (8-5√3) then expand and simplify
Y = 2x - 5...slope = 2, y int = -5
-8x - 4y = -20
-4y = 8x - 20
y = -2x + 5....slope = -2, y int = 5
different slopes, different y int's means 1 solution <==
** same slope, same y int = infinite solutions
** same slope, different y int's = no solutions
Answer:
The answer would be remove two negative tiles.
Step-by-step explanation:
-5-(-2) becomes -5+2, and since the latter aren't of the same sign, you'd subtract two negative tiles so that it gives you the answer, which would be -3.
<u>How to:</u>
-5-(-2)
-5+2
= -3
Answer:
1.5 dollars/miles
Step-by-step explanation:
Given function can be used to determine cost in dollars for a taxi ride of x miles.
Now we need to find about what is the rate of change of the cost in dollars with respect to the number of miles.
First we need to rewrite in y=mx+b form
comparing with y=mx+b, we get m=1.5
Hence rate of change of the cost in dollars with respect to the number of miles is 1.5.
