11-2x would be the answer u are looking for. Hope this helps!
Answer:
y + 9 = -0.4(x-7)
Step-by-step explanation:
in slope form , we will use y - y1 =m ( x - x1) ,
which will be y + 9 = -2/5(x-7) ,
in reduced form , we have y + 9 = -0.4(x-7)
We use the given data above to calculate the volume of gasoline that is being burned per minute by commercial airplanes.
Amount burned of 1 commercial airplane = <span>3.9 × 10³ ml of gasoline per second
Number of airplanes = </span><span>5.1 × 10³ airplanes
We calculate as follows:
</span> 3.9 × 10³ ml of gasoline per second / 1 airplane (5.1 × 10³ airplanes)(60 second / 1 min ) = <span>1.2 x 10^9 mL / min</span>
7 x 21 is equivalent to 21 x 7
also 3 x 49
