Hello! So the equation you have to solve is 49 + j = 81.  You want to figure out j, so you have to isolate the variable. This means, you should subtract 49. In math, if you do something to one side of the equation, you have to do it to the other. So, you must subtract 49 from 81. This means j= 32.

I hope this helps! If you need help with how to do the subtraction equation 81-49, please let me know!

Given the exponential function f(x) = 16(0.75)x, classify the function as exponential growth or decay and determine the percent
vagabundo [1.1K]

Answer:

The answer is Exponential decay, 25% decrease

Step-by-step explanation:

In f(x) = 16(0.75)x the (0.75) does not have a 1 so it is decreasing and if it is only 75% of 16 then it would be losing 25% each time

A relationship between two variables in which the product is a constant. When one variable increases the other decreases in proportion so that the product is unchanged. If b is inversely proportional to a, the equation is of the form b = k/a (where k is a constant). Equation: y = 60/x

Please I need help on this question
Yanka [14]

Step-by-step explanation: i hope this helps :)

Simplifying

g(x) = 5x + -1

Multiply g * x

gx = 5x + -1

Reorder the terms:

gx = -1 + 5x

Solving

gx = -1 + 5x

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Divide each side by 'x'.

g = -1x-1 + 5

Simplifying

g = -1x-1 + 5

Reorder the terms:

g = 5 + -1x-1
