Graph the equation-5x-2y=-10 by plotting the points
bearhunter [10]

Answer:

y = -2.5x + 5

Explanation:

Convert -5x - 2y = -10 into slope-intercept form: y = -2.5x + 5

You can start solving for and graphing points by putting numbers in for 'x' in the equation, and the answer you get out will be y.

Ex: -2.5(7) + 5 = -12.5

7 is the number we inserted for x, so it is the x value. -12.5 is the number we got out of the equation, so it is the y value.

The points will now look like this: (x, y) but for the example they would look like (7, -12.5)

Plot the numbers, x being on the horizontal axis, y being on the vertical axis.

Tju [1.3M]

Answer:

Four hundredths

In standard form - 4\times 10^{-2}

Step-by-step explanation:

Given : The green darner is one of the largest dragonflies.

It weighs about four hundredths of an ounce.

To write : Four hundredths in standard form.

Solution :

Standard form is when we write a larger number in a smaller way.

For example : 20000= 2\times 10^4

So, according to question

Largest dragonflies weighs about four hundredths of an ounce.

Four hundredths means 0.04

In standard form - 4\times 10^{-2}
