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
You got divide só see mean, the middle number is the median, range you add all number and divide but how many number has
C. 28 is the answer
Staring from the brackets we have 4+(-8) we can open the parentheses and get 4-8 and get -4. Now we can open the -7 up and now we have
-4 * -7 = 28
Hope this helps!
9
Step-by-step explanation:
I don't no but 5 and 1 is 6 so add 9 more and you have 15
The picture is a bit blurry but the perimeter of a shape is the lengths added.
(4a - 2b) + (7a + 3) + (9a - 4) = perimeter, I added the sides together
Combine like terms to get:
4a + 7a + 9a = 20a
-2b is left along becuase there are no other like terms
3 - 4 = -1
The perimeter is 20a - 2b - 1
