<span>A technique for mental multiplication is called factoring the tens which relies on the fact that 10*n, for any real number n. This will make the problems easy to compute. 6 x 2 = 12 is a memory value. </span>
12 x 10 = 120
12 X 100 = 1200
Take for instance in 6 x 2, 6 x 20 and 6 x 200. Find the factors and these are the computations. We can also say:
<span>6 x 20 = 6 x 2 x 10 = 12 x 10 = 120
60 x 20 = 6 x 10 x 2 x 10 = 12 x 10 x 10 = 1200</span>
It must be remembered that in the commutative and associative properties of multiplication, the order of the factors does not matter when solving this kind of problem
Answer:
y - 5 = 1/3(x - 0)
Step-by-step explanation:
the formula for point-slope form is y2 - y1 = m(x2 - x1), where m is the slope, y1 is the y coordinate and x1 is the x coordinate
so just plug in the values into the equation:
y - 5 = 1/3(x - 0)
if you want it in slope-intercept form, the formula is: y = mx+b, where mx is the slope and b is the y intercept. it would look like the following:
y = 1/3x + 5
