Answer:
store a
Step-by-step explanation:
Store A: 25% off on $80 is $20, so the sneakers would be $60. Take 10% of $60 to get $6 off. The sneakers at Store A would cost $60 - $6 = $54. Store B: 20% off on $80 is $16, so the sneakers would be $64. Take 15% of $64 to get $9.60 off. The sneakers at Store B would cost $64 - $9.60 = $54.40.
The estimate, 4 × 5 = 20, helps me
know that the decimal point should be placed so that the answer is close to 20.
(1,1)(-1,5)
your answer would be m=-2
hope this helped.
Answer:
Step-by-step explanation:
<u>Find the derivative of the function when x=3</u>
<u />
Since the change in the value of the function is 
and we know that the change in x is 
, then we have:
Therefore, the 2nd option is correct

Answer:
(0,-1)
Step-by-step explanation:
Let the ends of the line segments be A(-4,3) and B(5,-6).
Ratio=4:5
By the concept of cordinate geometry,
x=(mx2+nx1)/(m+n)
y=(my2+ny1)/(m+n)
where m and n is the ratio m:n.
So, here the cordinates are
x={4(5)+5(-4)}/(4+5)
x=(20–20)/9
x=0
y={4(-6)+5(3)}/9
y={-24+15}/9
y=(-9)/9
y=(-1)
Therefore the cordinates of the point that divides the given line segment in the ratio 4 : 5 is (0,-1)
