tekilochka [14]

Answer:

1.2 x 10⁴

Step-by-step explanation:

12,000 has 2 places of other numbers before a spam of zeroes.

Take the numbers before zeroes and put a decimal to the left of the last digit.

Last digit is 2 so a decimal goes before 2

1.2

Count how many places the decimal moved: this number is your power of 10.

It moved 4 places.

12,000 = 1.2 x 10⁴

How would i graph <br> y=− 5/2x-3<br> and<br> x−y=−4<br> (_,_)
SashulF [63]

Given:

The system of equations is

y=-\dfrac{5}{2}x-3

x-y=-4

To find:

The graph of the given system of equations and its solution.

Solution:

The table of values for y=-\dfrac{5}{2}x-3 is

x        y

-4       7

-2       2

0      -3

Plot these points and connect them by a straight line.

The table of values for x-y=-4 is

x          y

-4         0

-2         2

0         4

Plot these points and connect them by a straight line.

From the below graph it is clear that the lines intersect each other at point (-2,2).

Therefore, the solution of given system of equation is (-2,2).
