Only three terms luckily:
8*(1/4)^0 + 8*(1/4)^1 + 8*(1/4)^2 =
8*(1 + 1/4 + 1/16) = 21/2, answer D.
Let's solve your equation step-by-step:
It's always easiest to rewrite the equation, so let's do that -
5 - 1/2x = 12
Step 1) Simplify both sides of the equation
-1/2x + 5 = 12
Step 2) Subtract 5 from both sides
-1/2x = 7
Step 3) Multiply both sides by 2/(-1)
(2/-1) * (-1/2x) = (2/-1) * 7
x = -14
FINAL ANSWER --
x = -14

Answer:
<h2>h = 12</h2>
Step-by-step explanation:
To find the value of h use the formula for finding the slope of a line
That's
![m = \frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20)
Where ( x1, y1) and (x2 ,y2) are the points
From the question
slope = - 3
The points are [4,-9] and [-3,h]
Substitute these values into the equation
We have
![- 3 = \frac{h + 9}{ - 3 - 4}](https://tex.z-dn.net/?f=%20-%203%20%3D%20%20%5Cfrac%7Bh%20%2B%209%7D%7B%20-%203%20-%204%7D%20)
![- 3 = \frac{h + 9}{ - 7}](https://tex.z-dn.net/?f=%20-%203%20%3D%20%20%5Cfrac%7Bh%20%2B%209%7D%7B%20-%207%7D%20)
Cross multiply
That's
- 3(-7) = h + 9
21 = h + 9
h = 21 - 9
We have the final answer as
<h3>h = 12</h3>
