love history [14]

Answer:

252000

Step-by-step explanation:

we take 2.52 and move the decimal back 5 places. when we run out of numbers we add zeros. so if we moved 3 places back it would be 2520 but since we move 5 it is 252000. 10 by any power you just move the decimal place if it is negtive move it forward if positive move backward.

The graph of the line with the equation y = 1/2 * x + 4 crosses the x-axis at which of the following
svlad2 [7]

Answer:

Step-by-step explanation:

so we are looking for the x intercept (where the line crosses the x axis).

to do this, we sub in 0 for y and solve for x.

y = 1/2x + 4....sub in 0 for y

0 = 1/2x + 4

-1/2x = 4

x = 4 * -2

x = -8 <=== so it crosses the x axis at (-8,0)
