The volume of a cube is s^3, where s is the length of a side.
If you have 84 cubes with sides of 1/3 in, the total volume is:
V=84(1/3)^3 in^3
V=84/27 in^3
V=28/9 in^3
V≈3.11 in^3 (to nearest hundredth of a cubic inch)
Answer:
gradient = 2
line: y = 2x - 4
Step-by-step explanation:
Find the slope from the slope intercept formula
y = mx + b
b is the y intercept
b = -4 and the point is (0,-4)
So far the equation looks like this.
y = mx - 4
Use the other intercept (x intercept) to find m
x = 2
y = 0
0 = m*2 - 4 Add 4 to both sides
4 = 2m Divide by 2
4/2 = m
m = 2
So the gradient or slope is 2
(Hard to put it in words for me so here is a picture)
Or you can use point-slope form (
) and insert the slope of -2 and the point (3,6) like this:
And simplify if needed.
Have a great day!
