Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0, or (0,y))
Rise is the number of units you go up(+) or down(-)
Run is the number of units you go to the right
y = -2x
This has a y-intercept of 0, so the line intersects the y-axis/goes through the origin at (0,0)
The slope is -2 or 
, so from each point, you go down 2 units, and to the right 1 unit.
Answer:
Im pretty sure the answer is B) f=2.5b
Answer:
-h - 6
Step-by-step explanation:
(6h + 2) + (-7h - 8) <== remove parenthesis
6h + 2 - 7h - 8 <== combine like terms
6h - 7h + 2 - 8
-h - 6
Hope this helps!
Answer:
x = 0, π/4, π, 7π/4
Step-by-step explanation:
sin(2x) = √2 sin x
Use double angle formula.
2 sin x cos x = √2 sin x
Move everything to one side.
2 sin x cos x − √2 sin x = 0
Factor.
sin x (2 cos x − √2) = 0
Solve.
sin x = 0, cos x = ½√2
x = 0, π/4, π, 7π/4
Answer: Answer for 27 , It dropped 38 feet, (down) so -38 feet
Answer for 28, The difference between 4 and -7 is 11
Step-by-step explanation:
25 + 13 = 38 (but it was going down so its negative)
4 + 7 = 11
