Answer:
y = ix + 6i + 4
Step-by-step explanation:
Since the line has undefined slope or indefinite slope we connote that the slope is (i)
Slope(m) of straight line = change in y ÷ change in x
Taking another point (x,y) on the line:
i =
i =
Cross multiplying gives;
y - 4 = ix + 6i
y = ix + 6i + 4
Answer:
Step-by-step explanation:
-6q + 7 - 2 + 4q
u can only add and subtract like terms....if there not like terms, u cannot add or subtract them
another words, u cannot add/subtract -6q + 7 because these are not like terms
so lets gather our like terms
-6q + 4q = -2q
7 - 2 = 5
so ur answer is : -2q + 5 <====
Divide 4w to every term separately.
48/4 = 12
w^3/w = w^2
So our first term is 12w^2.
128/4 = 32
w^2/w = w
So our second term is 32w.
4w/4w = 1
Anything divided by itself is 1.
-1/4w, this can't be simplified further, so this is our last term.
So we have:
For problem 17, if you double the diameter of the moon, then the surface increases by a factor of 4 and the volume by a factor of 8.
<h3>
How to compare the change in surface and volume?</h3>
Let's answer question 17.
Remember that for a sphere of radius R, the volume is:
And the surface area is:
So the volume depends on the cube of the radius and the surface on the square of the radius.
Now, if we double the diameter of the moon, then we also double the radius.
So the new volume will be:
The new volume is 8 times the original volume.
And for the surface:
So the new surface is 4 times the original surface.

Answer:
3p^3 + qp^2 - pq^2 + 3q^3
Step-by-step explanation:
(p²-pq + q²) ( 3p+ 3q)
3p^3 + 3qp^2 - 3qp^2 - 3pq^2 + 3pq^2 + 3q^3
3p^3 + qp^2 - pq^2 + 3q^3
