Opposite angles are supplementary, so you have
.. V +T = 180°
.. (15y -4) +(12y-5) = 180
.. 27y -9 = 180
.. y = 189/27 = 7
a) T = (12y -5)° = (12*7 -5)° = 79°
c) V = (15y -4)° = (17*7 -4)° = 101°
.. U +W = 180°
.. (14 +4x) +(6x -14) = 180
.. 10x = 180
.. x = 180/10 = 18
b) U = (14 +4x)° = (14 +4*18)° = 86°
d) W = (6x -14)° = (6*18 -14)° = 94°
F(x) = 50x
independent variable = x
dependent variable = f(x)
f(x) = 50x......find f(6)
f(6) = 50(6)
f(6) = 300
Answer:
(1,4)
Step-by-step explanation:
2x-3y=-10
y=4x
Since the y is already isolated, you can use substitution to find the answer to this equation. Simply replace any y values in the first equation with 4x:
2x-3(4x)=-10
2x-12x=-10
-10x=-10
x=1
y=4(1)=4

Surface area=area needed to wrap a box
volume=amount of space in the box
surface area=2hl+2hw+2wl=2(hl+hw+wl)
volume=hlw
h=height
l=legnth
w=width
a. surface area is the outside area. lets say you have a cardboard cube and cut it on all the corners and edges so you ended up with 6 squares, the total areas of those squares is the surface area of the cube
volume is how much stuff can be put into the cube, we measure how many 1 by 1 by 1 cubes can fit into the object or how much water can fit in the cube
b. surface area is 2 dimentional since it is area and can be folded flat so the units would be square feet or square inches (ft^2, in^2)
volume is 3 dimentional since it is legnth width and height so it would be cubic foot, cubic inch (in^3, ft^3)
c. surface area=wrapping paper, wrapping stuff, painting an object
volume=how much water can fit in pool, how much punch to put in the jar to fill it up, which water bottle to bring so you have enough water
