Yes it is, due to the fact that you can see exactly what you are subtracting because they are directing above and below each other. In all forms of math we subtract this way for a better understanding of what's needed to be subtracted.
To solve for x, you need to isolate/get the variable "x" by itself in the equation:
x - 60 = 180 Add 60 on both sides to get "x" by itself
x - 60 + 60 = 180 + 60
x = 240
PROOF
x - 60 = 180 Substitute/plug in 240 into "x" since x = 240
240 - 60 = 180
180 = 180
Hello!
You go by the notation of the triangles
AB = PQ
Since both of them are the first two letters to label the triangles this is true
------------------------------------------------------------------------------------------------------
<R = <C
Since they are both the last letter in the triangles this is also true
------------------------------------------------------------------------------------------------------
<C = <P
They are not in the same place so this is not true
------------------------------------------------------------------------------------------------------
<A = <Q
Since they are in different spots this is not true
------------------------------------------------------------------------------------------------------
BC = PQ
Since they are in different spots this is also not true
------------------------------------------------------------------------------------------------------
AC = QR
Since they are in different spots this is not true also
------------------------------------------------------------------------------------------------------
The answers are A and B
Hope this helps!
Answer:
Step-by-step explanation:
a.) the maximum is just the vertex
-35/(2*-4.9)= it takes 3.5714 seconds to hit the maximum
which in height is
-4.9*3.5714^2+35*3.5714 +1= 63.5 metres
b.) for this just plug in 2
-4.9*2^2+35*2+1= 51.4 metres
c.) just plug in f(0) =1 meter
d.) find the x intercepts (using the quadratic formula)
seconds
(there is another answer but it doesn't make sense in the context of this question)
