8p + 3q - 18 when p = 1/2 and q = 7

You are given that p is equal to 1/2 and q is equal to 7, so plug these values into p and q in the expression to find your answer.

Rewrite your expression to include the values of p and q plugged in. Your expression should look like:

8(1/2) + 3(7) - 18

According to PEMDAS, multiplication should be solved first before doing subtraction, so multiply 8 by 1/2 and 3 by 7. Rewrite your expression; your expression should look like this:

4 + 21 - 18

According to PEMDAS, addition and subtraction should be solved from left to right; they are not prioritized. So solve the expression from left to right and then you will have your answer.

4 + 21 = 25

25 - 18 = 7

Your answer is 7.

Solve the equation. Check for extraneous solutions. Type your answers in the blanks. Show your work. |4x+3| = 9+2x
GaryK [48]

Answer:

Step-by-step explanation:

|4x + 3| = 9 + 2x

We see the absolute value so we have to consider 2 cases:

(1)

4x + 3 = -9 - 2x

6x = -12

x = -2

(2)

4x + 3 = 9 + 2x

2x = 6

x = 3

Let's plug in both results.

|4(-2) + 3| = 9 + 2(-2)

|-5| = 9 - 4

5 = 5

Therefore x = -2 is a solution

|4(3) + 3| = 9 + 2(3)

|15| = 9 + 6

15 = 15

Therefore x = 3 is also a solution.

An exponential function is expressed in the form y=axb^x. The relation represents a growth when _______ and a decay when ______.
seropon [69]

Answer:

Growth when: b>1.

Decay when: 0<b<1.

Step-by-step explanation:

Any function in the form f(x)=a{\times}b^x , where a > 0, b > 0 and b not equal to 1 is called an exponential function with base b.

If 0 < b < 1 this is an example of an exponential decay.

The general shape of an exponential with b > 1 is an example of exponential growth.

Hence,

An exponential function is expressed in the form f(x)=a{\times}b^x,   The relation represents a growth when  b >1 and a decay when 0<b<1.
