Answer:
x = 1.3
Step-by-step explanation:
15 - 4x = 2(3x + 1)
15 - 4x = 6x + 2
-2 -2
--------------------------
13 - 4x = 6x
+4x +4x
--------------------------
13 = 10x
/10 /10
---------------------------
1.3 = x
Answer: You divide the degree measure of the arc by 360 degrees.
Step-by-step explanation:
Hello,
505/1 000 = ( 505 / 5 ) / ( 1 000 / 5 ) = 101/200
Bye :)
Answer: B) x ≥ -2
<u>Step-by-step explanation:</u>
Domain represents all of the x-values.
In the given graph, the x-values start at -2 and go continuously through to positive infinity.
Therefore, x ≥ -2
Answer:
the vertex of the parabola is at the point; (5, -1)
which agrees with answer "B" in the list of options
Step-by-step explanation:
Notice that this is the equation of a parabola with branches that open horizontally (not vertically), since the variable the goes squared is the y-variable instead of "x".
By analyzing it we can then write it by isolating the term in "x" on one side of the equation, and use at the same time the fact that it is being written in "vertex" form:

Therefore, the "y-value" of the vertex must be that which renders zero in the expression squared, that is y = -1. On the other hand, the x-value of the vertex is that which renders zero for the variable "x": x=5.
Then, the vertex of the parabola is at the point; (5, -1)
