X > = 75 (thats greater then or equal)
Answer: 48
Step-by-step explanation:
6(x+y) take the 10 and plug it in for x and then take the -2 and plug it in for y. Now you have 6(10+-2) or 6(10-2) or 6(8)= 6X8= 48
Answer:
BC = 280ft
Step-by-step explanation:
Because it's a symmetry diagram
the same angles and lengths.
Hope this helps :)
Answer:
36.66 ft
Step-by-step explanation: You have to use the pythagorean theorem. a^2 + b^2 = c^2 (if you lean a ladder against a wall, it will make the shape of a triangle) The hypoteneuse would be 40 feet as it is the height of the ladder (the longest side). The one of the legs would be 15 ft (how far it is from the base of the house). You would then just plug the numbers in : a^2 + 15^2 = 40^2
a^2 + 256 = 1600
a^2 = 1344
a = 36.66
Well, in order to first determine the slope or y-intercept, you must put change the equation to this format: y=mx+b.
m=slope and b=y-interceptI
in order to do that, you must change this equation.
x+3y=9
-x -x
----------
3y=9-x
Then, rewrite it as:
3y=-x+9
_______
3 3
simplify to
y=-x/3 +9
