The first one is true and so is the second one.

When you graph the function, every x value (or input) has only one y value (or output). If the line weren't straight then there could be multiple inputs and outputs which would mean it isn't a function

Pay attention here because I'm adding an extra letter to our circle to help keep track of the values in our formula.  OUTSIDE of the intercepted arc I'm adding the point E.  So the major arc is arc BEG and the minor arc is arc BG.  The formula then for us is ∠BFG= \frac{1}{2}(arcBEG-arcBG).  We just don't have values for the arcs yet.  If the measure of the central angle is 4x+238, then the measure of arcBG is also 4x+238.  Around the outside of the circle is 360°.  So we will use it in an expression.  ArcBEG=360-(4x+238).  Fitting that into our formula we have 2x+146= \frac{1}{2}[(360-4x-238)-(4x+238)].  Doing all the simplifying inside there we have 2x+146= \frac{1}{2}(122-4x-4x-238) and 2x+146= \frac{1}{2}(-8x-116).  Multiply both sides by 2 to get rid of the fraction: 4x+292=-8x-116.  Combine like terms to get 12x = -408 and divide to solve for x.  x = -34.  Fourth choice down from the top.

Which sequence of transformations produces R’S’T’ from RST?
inn [45]

Answer:

A translation 2 units right and then a reflection over the x-axis

Step-by-step explanation:

The given vertices of ΔRST are R(0, 0), S(-2, 3), and T(-3, 1)

The vertices of triangle ΔR'S'T' are (2, 0), (0, -3), (-1, -1)

The points are plotted with the aid of MS Excel, and by observation, we have that the image of ΔRST is located on the other side of the x-axis with each coordinate on ΔR'S'T' shifted 2 units to the right of ΔRST

A translation of ΔRST 2 units right gives;

(0 + 2, 0) = (2, 0), (-2 + 2, 3) = (0, 3), and (-3 + 2, 1) = (-1, 1), to give;

(2, 0), (0, 3), and (-1, 1)

A reflection of the point (x, y) across the x-axis gives (x, -y)

A reflection of the above points across the x-axis gives;

(2, 0) reflected about x-axis → (2, 0) reflected about x-axis → (0, -3), and (-1, 1)  reflected about x-axis → (-1, -1), which are the points of ΔR'S'T'

Therefore, the sequence of transformations that produces R'S'T' from RST are;

A translation 2 units right and then a reflection over the x-axis
