Since the slope-intercept form of a line is given by the expression:
Where, m is the slope and b is the y-intercept.
Then, for the function:
The slope is -2 and the y-intercept is (0, 3)
Answer:
x = 10
Step-by-step explanation:
Since the triangles are similar the ratios of corresponding sides are equal
= , that is
= ( cross- multiply )
20(4x + 2) = 84x
80x + 40 = 84x ( subtract 80x from both sides )
40 = 4x ( divide both sides by 4 )
x = 10
You are multiplying by 10 each time so it is:
.02, 0.2, 2, 20, 200, 2000
