The answer is A, because if you look, it 55 is the mid range.
Answer:
AC = DF, AB/BC=DE/EF
Step-by-step explanation:
Basically either subsitute or solve
I will simplify to make easier work
so PEMDAS
Parenthasees
Exponents
multiply or divide whichever comes first
add or subtract whichever comes first
9 times 8=72
I will assume that x2=x^2 or x squared so left is simplified
x^3+x^2 so
72-2x+x^2<u>></u>x^3+x^2
subtract x^2 from both sides since they cancel each other out
72-2x <u>></u> x^3
add 2x to both sides
72 <u>></u> x^3+2x
factor
72 <u>></u> x(x^2+2)
now subsitute 7,6,5,4
if x=4 then
4(4^2+2)=4(16+2)=4(18)=72
72 <u>></u> 72
true
since all the other numbers are smaller, the only sentence that will work is 7 or A
the answer is A 7
Answer: The required co-ordinates of point T are (13, -6).
Step-by-step explanation: given that S is the midpoint of the line segment RT, where the co-ordinates of point R are (-9, 4) and that of S are (2, -1).
We are to find the co-ordinates of point T.
We know that
the co-ordinates of the mid-point of a line segment with endpoints (a, b) and (c, d) are given by
Let (h, k) be the co-ordinates of point T. Then, according to the given information, we have
and
Thus, the required co-ordinates of point T are (13, -6).
The midpoint is the number exactly between the numbers
0+4= 4
4/2 = 2
