Answer:
x = 8 - y
Step by step explaination:
==>x + y = 8
==> x = 8 - y
==> substract the value
==> Done
If it was in standard notation it would be very confusing to add the number of cells and it would be less organized.
Answer:
1.
Step-by-step explanation:
1) if sin30=0.5; tan45=1; tan30=1/√3; sin60=√3/2, then
2) 0.5+0.5=1.
I’m sorry i don’t know the answer but i need to ask another question but i gave up answer a question first sorry
Answer:
f(x)=4x(x-3)
Vertex=3/2, -9
Step-by-step explanation:
First, factorize it.
That is equal to 4x(x-3)
Therefore, x intercepts are 0 and 3, as at least one of them need to be 0.
To find the vertex, first find the x of the vertex, which you can do by finding the average of the x intercepts, so it will be 3/2
Then, find the y, by making x in the original equation equal 3/2. This will give us -9 as the y.
The vertex will by 3/2, -9
