Find the coordinates of the new points of each figure after given transformation without graphing paper and write the rule Help I need this done in less than 6 hours Reflection across the x-axis: Q(0,-1) D(-2,2) V(2,4) J (3,0) what rule is (x, y)
Reflection across y=x: D(-4,1) A(-2,5) S(-1,4) N(-1,2) what rule is (x, y)
Reflection across y-axis: T(1,-3) I(-2,-2) E(5,4) what is the rule for (x, y)

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
