bearing in mind that perpendicular lines have negative reciprocal slopes, hmmm what's the slope of the equation above?

so we're really looking for the equation of a line whose slope is 2 and runs through (2,-5),
Answer:
f(5)=1/22
Step-by-step explanation:
f(5)=-2/-5(5)-19
f(5)=-2/-25-19
f(5)=-2/-44
f(5)=1/22
Answer:
6 batches
Step-by-step explanation:
24 people x 4 cupcakes = 96 cupcakes
96 cupcakes / 16 per batch = <u>6 batches</u>
Hope this helped, have a nice day! :)
Answer:
0.25/ 25%
Step-by-step explanation:
I=prt
1200=960*x*5
1200=4800x
divide both sides by 4800
x=0.25
