Answer:
Step-by-step explanation:
well, in the equation y = kx
the constant or proportionality is k.
So, what do you think?
Answer:
Step-by-step explanation:
We are given the function f(x) = -3/4(x) +6.
We know that the slope intercept form of a line is y = mx + b
Here, the slope m = -3/4.
The y-coordinate of the y intercept is b = 6 so the y-intercept is at the point (0,6) [x is always 0 at the y-intercept]
If you have to points you can graph the line, we only have the point (0,6).
To find the second point we use the slope.
We add the bottom point of the slope to the x coordinate of the y-intercept and we add the top part of the slope to the y coordinate of the y-intercept, so our second point is (0 + 4, 6 +(-3)) = (4, 3).
You then plot the points we have: (0,6) and (4,3) and draw the line through them.
Answer:
The vertex is
Step-by-step explanation:
For a general quadratic function the form is:
For the function
Take common factor 3.
The values of the coefficients for the function within the parenthesis are the following: , ,
Take the value of b and divide it by 2. Then, the result obtained squares it.
Add and subtract
Write the expression of the form
The vertex is
For a geometric sequence with common ratio
, we have
that is, the
-th term in the sequence is the product of the previous term and the common ratio
. So
Then the sum of the first 7 terms is
Notice that
so we can subtract this modified sum from
to get
We're told that
and
, so the sum of the first 7 terms is
(this is for fractions!!!!!!!!!!!!) 28/5 or 5 3/5
i think u just make it into 5.6/1 multiply by 10 which gets 56/10 and wala
but it's not simplified. 56 and 10 is divisible by 2 so u get 28/5 which is actually 5 3/5 (which is 5.6!!)
