Estimate how many times larger 6.1x10^7 is than 2.1x10^-4

2.9 x 10¹¹ ≈ 300,000,000,000 times larger

Step-by-step explanation:

6.1x10⁷ / 2.1x10⁻⁴ = 2.9 x 10¹¹ ≈ 300,000,000,000

300,000,000,000

Step-by-step explanation:

6.1 x 10^7 = 61,000,000

2.1 x 10^-4 = 0.00021

= 2.9 x 10^11 = 290,000,000,000

rounding would be 300,000,000,000

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
