Steps:
5x - 2y = 30
5(8) - 2y = 30
40 - 2y = 30

11x+6y=-48 slope intercept

lesya [120]

Answer:

y = -11/6x - 8

Step-by-step explanation:

<u>Step 1: Solve for y</u>

11x + 6y = -48

11x + 6y - 11x = -48 - 11x

6y / 6 = (-48 - 11x) / 6

y = -8 - 11/6x

Answer: y = -11/6x - 8

The cloth shop has announced a reduction in price by 25%. How many shirts priced at Rs 28 should buy to avail a total reduction

Drupady [299]

Answer:

At least 6 shirts should be brought to avail a total reduction of Rs 40.

Step-by-step explanation:

The marked price of each shirt = Rs 28

Discount offered = 25%

So, 25% of marked price 28 = $\frac{25}{100} \times 28 = 7$

⇒Reduction on each shirt is Rs 7

Now, total amount reduction needed = Rs 40

So, number of shirts purchased = $\frac{\textrm{Total reduction needed}}{\textrm{Reduction on each shirt}}$

= 40 Rs /7 Rs = 5. 71 ≈ 6

So, at least 6 shirts should be brought to avail a total reduction of Rs 40.
