What is the equation in standard form of the line that passes through the point (1, 24) and has a slope of -0.6.
lana [24]

Answer:

0.6x+y=24.6

Step-by-step explanation:

y-y1=m(x-x1)

y-24=-0.6(x-1)

y=-0.6x+0.6+24

y=-0.6x+24.6

y-(-0.6x)=24.6

y+0.6x=24.6

0.6x+y=24.6

The cost of a phone has increased by 10% to £352 work out the original price
lions [1.4K]
The answer is £316.80.

This is because you're working out the original price from a percentage increase.

To do this, you do the original price ÷ (1- percentage increase as a decimal).

So it would be 352 ÷ (1 - 0.10) which is 352 ÷ 0.9.

And that equals to £316.80.
