Mathematics

givi [52]3 years ago

Answer:

Step-by-step explanation:

The easiest way to do this is to solve for x first, then y.

Plug the second equation (y = 2x - 5) into the first equation (-3x - 4y = -2).  This will give you -3x - 4(2x - 5) = -2.  Solve for x.

-3x - 4(2x - 5) = -2

-3x - 8x + 20 = -2

-11x = -22

x = 2

Now, you can plug in the x-value into the second equation.

y = 2(2) - 5

y = 4 - 5

y = -1

standard form should be less than 10. therefore, count decimal places from where the decimal point is located to the right until you reach a number less than 10 ....count the number of shifts in the above is 6 shifts to the right. when moving to the right, power will be negative.(-6)

1.157/1.16 ×10^-6

b) 6.79 × 10^10

67890000000....count till a number less than 10.there will be 10 shifts to the left. the 10 will be your power,(positive) since u r moving to the left exponent is positive
