which equation does the graph of the systems of equations solve?

quadratic graph opening down and quadratic graph opening up. they intersect at 0, 3 and 3, 0.

a. x2 − 2x + 3 = 2x2 − 4x − 3
b. x2 − 2x + 3 = 2x2 − 4x + 3
c. −x2 + 2x + 3 = x2 − 4x + 3
d. −x2 − 2x + 3 = x2 − 4x + 3

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label

In need of in the diagram, ∠abc is a right angle. ∠dbc = 30°27'40". find the measure of ∠abd.

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
