C and E are the corrects answers
Answer:
B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.
Step-by-step explanation:
<u>Let's convert the standard equation into slope-intercept form:</u>
- Ax + By = C ⇒ subtract Ax from both sides
- By = -Ax + C ⇒ divide both sides by B
- y = -A/Bx + C/B ⇒ converted to slope- intercept form
As we see the slope is -A/B
<u>The equation 7x + 9y = 14 is converted as:</u>
- y = -7/9x + 14/9, where the slope is -7/9
<u>Looking at the answer options and the correct one is option B, where both identification of slopes match.</u>
- B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.
I have never see this in my. Life
Alright
so equation is
![A(t)=Pe^{rt}](https://tex.z-dn.net/?f=A%28t%29%3DPe%5E%7Brt%7D)
P=initial amount
and t=time
r=rate
given
initial amount is 50
rate is 10%, but decreasing by 10% so -0.1
and time=6
![A(6)=50e^{-0.1*6}](https://tex.z-dn.net/?f=A%286%29%3D50e%5E%7B-0.1%2A6%7D)
![A(6)=50e^{-0.6}](https://tex.z-dn.net/?f=A%286%29%3D50e%5E%7B-0.6%7D)
A(6)=27.4406
