Answer: a what test?
Step-by-step explanation:
y=x²-10x-7
a>0 so we will be looking for minimum
x=-b/2a=10/2=5
y=25-50-7=-32
Answer: (5;32)
y=-4x²-8x+1
а<0 so we will be looking for maximum
х=-b/2a=8/-8=-1
у=4+8+1=13
Maximum point (-1;13)
Answer:
MP = Rs. 1500
SP = Rs. 1230
Step-by-step explanation:
Let the Cost Price (CP) be x
<u>Then Market Price (MP):</u>
<u>Discounted Selling Price (SP):</u>
- SP = MP - 18% = 0.82*1.2x = 0.984x
<u>Since the difference between CP and SP is Rs.20:</u>
- x - 0.984x = 20
- 0.016x = 20
- x= 20/0.016
- x = 1250
<u>Then:</u>
and
- SP = 1500*0.82 = Rs. 1230
Yo! This is the answer. Hope it helped
