an equation is an identity if both sides of the equation are equal to one another

Step-by-step explanation:

for example the equation x plus 1 draw x plus 1 is an identity bc plus 1 obviously is equal to x plus 1❤

I think the first one

Step-by-step explanation:

9-(2v+3)=2v-6 = -2v-6

Let me know if it's right!

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.
