A cube is a solid box whose every surface is a square of same area.
Take an empty box with open top in the shape of a cube whose each edge is 2 cm. Now fit cubes of edges 1 cm in it. From the figure it is clear that 8 such cubes will fit in it. So the volume of the box will be equal to the volume of 8 unit cubes together.
-3x-2-6x=-4-<em>(-4x)</em>+12
-9x-2=-16x+12
7x=14
x=2.
You probably got confused with the italicized part.
Answer:
b = -6.5
Step-by-step explanation:
I am 100% sure thts the right answer
The right triangle has legs of x and 2.5 where x is the height up the wall that the ladder will reach. The length of the ladder is the hypotenuse of the right triangle.
According to the Pythagorean Theorem, x^2 + 2.5^2 = 12^2
x = 11.736 approx To the nearest tenth that is 11.7.
We can write the function in slope-intercept form (y + mx + b). Since we have the slope, we can solve for the y-intercept.
y = -2x + b
4 = -2(0) + b
4 = b
Input the data we have now.
y = -2x + 4
Since we are dealing with a function switch out the y for f(x)
f(x) = -2x + 4
Best of Luck!
