Answer:
tHE FIRST OPTION
Step-by-step explanation:
A colon is representative of a ratio
for example
1:2 is a ratio
Subtract 6 which leaves u with -3p=-18 then divide by three on both sides to get p=6
<span>(((-3) + (-13)) / 2, ((-3) + (-13)) / 2) </span>
<span>= (-16 / 2, -16 / 2) </span>
<span>= (-8, -8)
1 = D</span>
Answer:
8 months
Step-by-step explanation:
3/4 of a tube per month = 1.5 tubes for two months = 3 tubes for four months.
Double the 3 tubes for four months to get 6 tubes for 8 months.
To find the slope of a line that is perpendicular to the given line, we find the negative reciprocal of the given slope (flipped and made negative), so ½ would become -2/1 or simply -2. This gives us the equation y=-2x+b. To find b we plug in the coordinates the new line has to pass through, so ((-5)=-2(10)+b) = (-5=-20+b) = (15=b) or (b=15). So, the answer would be A. y=-2x+15
