Answer:

p= 9/4 - 3r/4

Step-by-step explanation:

Move 3r to the right and when you divide 4 from both sides and each variable, you are left with p= 9/4 - 3r/4 since you cannot simplify it more.

Answer:

p= -3/4r+9

Step-by-step explanation:

1. Subtract 3r from both sides of the equation to isolate p on one side of the equation

a. 4p+3r - 3r= 9 -3r

b. 4p=9-3r

2. Divide every term in the equation by 4

a. 4p/4=9/4 - 3r/4

b. p=9/4 -3r/4

3. Rearrange the equation (if need be) into slope-intercept form.

a. p= -3r/4 +9/4

Answer:

16,249 years old

Explanation:

The exponential decay model for carbon-14 is given below:

$A=A_0e^{-0.000121t}$

The paint contained 14% of the original carbon-14.

• A=14% = 0.14

• Ao = 100% = 1

$\begin{gathered} 0.14=e^{-0.000121t} \\ \text{ Take the ln of both sides} \\ ln(0.14)=ln(e^{-0.000121t}) \\ ln(0.14)=-0.000121t \\ \text{ Divide both sides by -0.000121} \\ t=\frac{ln(0.14)}{-0.000121} \\ t=16248.9 \\ t\approx16,249 \end{gathered}$

The paintings are approximately 16,249 years old.

X + 3y = 14 -5x + 6y = -28 Solve systems by substitution

mote1985 [20]

Rearrange the first system to get x = -3y + 14. Substitute that into the other system.

$-5x+6y=-28\\\\-5(-3y+14)+6y=-28\\\\15y-70+6y=-28\\\\15y-70+6y=-28\\\\21y-70=-28\\\\21y=42\\\\y=2$
