Which shows the expression below in simplified form? (7 × 10-3) - (2.3 × 10-6) a. 6.9977 × 10-3 b. 6.99977 × 10-3 c. 6.9977 × 10-4 d. 6.977 × 10-3

Option A

Solution:

Given expression is:

To evaluate the expression, let us make the exponent of 10 same

[ Here, decimal point is moved three times left, so add 3 ]

Therefore,

Thus Option A is correct

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
