Drag each tile to the correct box. not all tiles will be used.
arrange the steps to solve the equation vr 3-v2x-= -2
simplify to obtain the final radical term
on one side of the equation.
raise both sides of the equation to
the power of 2
apply the zero product rule.
use the quadratic formula to find the
values of x.
simplify to get a quadratic equation.

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

yes because they have the same amount of green and blur marbles.

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137

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
