Y=2x-1 is the point with coordinates (5,11) on the line y=ex-1? true or false

False

Step-by-step explanation:

Here, we want to check if the point given is on the line

To get this, we simply proceed to substitute the point given into the equation

Thus, we have;

11 = 2(5) - 1

11 = 10-1

11 is not equal to 9

Since these are not equal, then the point is not on the line

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
