Answer:
x = 5
Step-by-step explanation:
Using the tangent ratio and the exact value
tan60° = , then
tan60° = 
= 
= ( multiply both sides by 5 to clear the fraction )
x = 5
9the equation of a line in ' slope- intercept form ' is
y = mx + c ( m is the slope and c the y-intercept )
y = 3x + 1 is in this form
with slope = 3 and y-intercept = 1
the graph crosses the y- axis at ( 0, 1 )
from this point moving 3 units vertically up and 1 unit horizontally right gives the point (1, 4 ) . Repeating this gives the point (2, 7 )
Plot the points (0, 1 ), (1, 4 ) and (2, 7 )
Draw a straight line through them for graph of y = 3x + 1

Answer:
40% (decrease)
Step-by-step explanation:
150 - 250
|250|
× 100% =
Simplify the brackets first
So the first one which is
24x-8=8(3x-1)
24x-8= 24x-8
So it’s true
