Answer:
It is D
Step-by-step explanation:
I quickly skipped the question but i know it is D, it might be switched for you, but it is the longest sentence and says some things about intersection and stuff. ALSO I DID THIS ON USA TEST PREP
Answer:
You shifted up 3 units?
A 42
B 48
C 132
D 138
Answer:
D 138
Step-by-step explanation:
the outside angle(x) of a triangle whose base is extended is always equivalent to the farthest 2 inside angles of the triangle.
x = 48 + 90 = 138
Answer:
the standard form of a quadratic equation is ax² + bx + c
the vertex form is a(x - h) + k where h & k are the x and y coordinates
to get from standard form to vertex form, you would have to follow this formula to find h:
-b/2a
plug in the values, and you will get the value of h.
to get k, you plug in the value you have just found in the above formula into the original equation, and that is the value of k.
the a in the vertex form is the value of a in the standard form
so an example of this would be: x² + 2x + 4 where a = 1, b = 2 c = 4
to get this into vertex form we will use the formula -b/2a and solve:
-2/2(1) --> -2/2 = -1
now we plug in the value we found into the original equation wherever x is
(-1)² + 2(-1) + 4 --> 1 - 2 + 4 = 3
we have both h and k, and we will put this into vertex form:
a(x - h)² + k turns into ---> (x + 1)² + 3
why x+1 and not x-1? the original equation has a negative sign, and the result we have is negative. this conflicts with the original equation and is therefore turned into a positive 1
where did a go? since a = 1, we do not need to write it, if a was equal to 2 then we would write the 2 in front
y 6 15 ?
