Jill kept 5 colored pencils in her pencil pouch: one yellow, one red, one orange, one blue, and one black. she took one pencil from the pencil pouch without looking, but it was the wrong color. she put that pencil back in the pouch and took another pencil form the pouch without looking. what is the probability that jill selected the black pencil first and the orange pencil second? 1/18

2/15

1/9

1/5​

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

a - base

b - exponent

so,

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
