Answer:

16

Step-by-step explanation:

f ( x ) = 3x² - 2x

To find : f ( - 2 )

f ( - 2 ) = f ( x )

Here,

x = - 2

f ( - 2 ) = 3 ( - 2 )² - 2 ( - 2 )

           = 3 ( 4 ) - 2*( - 2 )

           = 3*4 + 4

           = 12 + 4

f ( - 2 ) = 16

Solve this equation for x. Round your answer to<br> the nearest hundredth.<br> 1 = In(x + 4)
KATRIN_1 [288]

Answer:

x ≈ - 1.28

Step-by-step explanation:

Using the rule of logarithms

log_{b} x = n ⇔ x = b^{n}

Given

ln(x + 4) = 1 , then

x + 4 = e^{1} ( subtract 4 from both sides )

x = e^{1} - 4 = - 1.28 ( to the nearest hundredth )

93 is the sum of a number g and 58
Wewaii [24]
Assuming you are hoping to obtain the value of "g", to solve worded algebra problems like these, it is easier to translate the world problem into a mathematical equation first.

In this case, "93 is the sum of a number g and 58" can be translated to:

93 = g + 58

To find the value of g, it is necessary to isolate g first. To do this, we subtract both sides of the equation by 58:

93 - 58 = g + 58 - 58
93 - 58 = g

Simplifying:
g = 35
