1) Draw the coordinate plane

2) Draw the line y = - 2

It is a line parallel to the y axis, two units below the origin

3) The solution (graph of the inequality y < - 2) is all the area below the line y = - 2.

Write 25x10 the power of 6 in standard from

forsale [732]

Answer:

25 * 10^6

But 10^6 is the same as multiply 10 six times, that is, 10 * 10 * 10 * 10 * 10 * 10 * 10. The result is as simple as writing 1 and six zeros, that is, counting the number of zeros I can see. So, 10^6 = 1000000.

Now, 25 * 10^6 = 25 * 1000000

The final answer is 25000000

The sum of two numbers is 80 If four times the smaller number is subtracted from the larger number, the result is 10. Find the t

timama [110]

This can be solved using a system of equations.
$\left \{ {{x+y=80} \atop {x-4y=10} \right. 
$
Subtract y from both sides.
$x=80-y$
Substitute:
$80-y-4y=80-5y=10$
Subtract 80 from both sides:
$5y=70$
Divide both sides by 5:
$y= \frac{70}{5} =14$
Substitute.
$x=80-14=66$
