Answer:
(-5,9)
Step-by-step explanation:
7 + 2 is 9 so yeah that's it
Answer:
The first one.
Step-by-step explanation:
For something to be considered to be a graph, every x value must have 1 y value. It does not matter if y values are the same, but you MUST make sure there is ONLY ONE of each value. So for example the second one wouldn't be a function because -5 appears twice for the x values, but with different y values. This would mean when graphed, it would fail the vertical line test (if you put a vertical line anywhere on the graph you will only get one point).
3/4 - 4 z + 5/4 z - 1/2 + 1/2 z
First, put the like terms together:
-4z + 5/4z + 1/2z + 3/4 - 1/2
Find the LCM of the first three to turn them into one massive fraction:
-16/4z + 5/4z + 2/4z + 3/4 - 1/2
Do the same for the last 2 fractions:
-16/4z + 5/4z + 2/4z + 3/4 - 2/4
Simplify everything (keeping like terms in mind)
-9/4z + 1/4
And that's the answer :)
(I think)
Answer: A. 12x
Step-by-step explanation:
14x-(2x-y)-y
14x-2x+y-y
Simplify = 12x
Answer:
If (2,0 )is a solution of a linear equation then the value of x=2 and value of y=0 if we put the value of x and y in the equation then
2x+3y=k
⇒k=2×2+3×0
⇒k=4
Hence the value of k=4
Thank you
