Answer:

2x-y = 1

Step-by-step explanation:

Equation of the line is y-y1 = m (x-x1), where m is the slope and (x1,y1) is a point that lies on the line.

Equation of the given line is,

y-(-1) = 2 *(x-0)

y+1 = 2x

2x-y = 1

What is greater than 100 inches or 3 yards and one of the

Nutka1998 [239]

To compare units either of them have to change to be the same unit

either change inches to yards, or yards to inches.

1 yard is 36 inches, so
3 yards = 3 × 36 = 108 in

100 in < 108 in

3 yards is greater.

An element with mass 130 grams decays by 22% per minute. How much of the element is remaining after 7 minutes, to the nearest 10

shepuryov [24]

22.8 grams of element will be remaining after 7 minutes

Further explanation:

Given

$Mass\ of\ element=130g\\Percentage\ of\ reduction=22\%$

The element reduces (1-22%) in one minute.

The process will be repeated 7 times for 7 minutes

If we have to calculate the amount of element after 7 minutes

then the total reduction will be: (1-22%)^7

$Remaining\ amount=130*(1-22\%)^7\\=130*(1-0.22)^7\\=130*(0.78)^7\\=130*0.18\\=22.84g\\Rounding\ off\ to\ nearest\ tenth\\=22.8g$

22.8 grams of element will be remaining after 7 minutes

The rectangle was basically cut into two right angles so all you have to find is the length of the triangle. Using what we know which is the h<span>ypotenuse and the height, use the equation x= the square root of c^2 - a^2.

The base is x = 9.17 in</span>
