Answer:
Step-by-step explanation:
well, in the equation y = kx
the constant or proportionality is k.
So, what do you think?
<h3>
Answer: Choice D</h3>
======================================================
Explanation:
The given equation is in slope intercept form y = mx+b
We see that m = 1/2 is the slope of y = (1/2)x-7
We'll use this slope along with the point (x1,y1) = (-3,-2) to get the following
Which is why choice D is the answer.
Note: this final equation is in point slope form.
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
