Answer:
Step-by-step explanation:
f(-3) = 2 * (-3)^2 h(6) = -4 * 6 g(-2) = 3*-2 -1 f(-4)= 2*(-4)^2
= 2* 9 = - 24 = -6 -1 = 2* 16
= 18 = -7 = 32

Answer:
Step-by-step explanation:
Note that √2x = √2*√x, and so we have √2*√x + 13 = √x + 31.
First subtract 13 from both sides, obtaining: √2*√x = √x + 18.
Next, group the √x terms together: √2*√x - √x = 18.
Now solve this for √x. We get:
√x(√2 - 1) = 18, or
18
√x = --------------
(√2 - 1)
To find x, square both sides:
18^2
x = ---------------
(√2 - 1)^2
We use unit rates in everyday day life, and it’s become quite useful. For example... : we use them to know how far a car or person can go ( with ) - a certain amount of time.
Unit Rates : When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour.
