3. Point B(0, -2) is translated 2 units left and 1 unit down. What are the
coordinates of the new point?
a. (-2, -3)
C. (2, -1)
b. (-1, -4)
d. (-1,0)

the correct answer is 5 6 and 7

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

the height of the surface increases from the center out to the sides of the road

it is c!

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
