if you want to know what scientific form is, its a method of writing or displaying numbers in terms of a decimal number between 1 and 10, multiplied by a power of 10.
It can also be the turning point on a graph. Like the minimum or the maximum of a parabola. (which is a U shaped curve)
a vertex is a point where two or more straight lines meet
first use distributive property
10K - 90 = -10
now add 90 to both sides
10K = 80
now divide both sides by 10
K = 8
and there's your answer!
a linear equation is an equation between two variables that gives a straight line when plotted on a graph.
so what i would do is turn both of the numbers into improper fractions.
3/2 divided by 8/3
now to divide, you have to multiply and use the recipricle
3/2 x 3/8 = 9/16
just turn 9216 into a fraction
9216 = 9216/1
now you equation is:
9216/1 x 1/27 = 9216/27 = 341.3 repeating or 341 1/3
(-4.13)(-0.8) = 3.304
all you have to do is turn 16 into a fraction by putting that number over 1
16 = 16/1
okay so now its 3/8 x 16/1
3/8 x 16/1 = 48/8
48/8 then simplifies to 6/1 which is 6
12y = 2 1/4 then divide by 12 on both sides
y = 0.1875
-91=-7n-8.
Add 8 to both sides.
-83=-7n now divide 83 by 7. That will be your answer
17*3=51
y = 3.6x or y = (18/5)x (if you prefer)
That's really all there is to it !!
Finally......here's 11
log625 5 + log6 216 we can use the change of base rule here .... logab = log b / log a
So we have
(log5 / log 625) + (log 216 / log 6) =
1/4 + 3 =
.25 + 3 =
3.25
And there you go....
You haven't indicated the base you are working in, but if it's base 5 or greater then the answer is 4.
If you are working in base 3, then the answer is written 11, because in base 3
2 + 2 = 11
Here's 10
logA = x logB = y ...so..... 3x + y =
3logA + logB =
logA3 + logB =
log (A3 B)
Here's 9
log [ (3√x * y2 ) / z ] so we have
log 3√x + log y2 - log z =
log x 1/3 + log y2 - log z =
(1/3)log x + 2 log y - log z
