Find Slope:
--------------------------------------------------------------------------------------------------------
y = 1/4x - 7
Slope = 1/4
Perpendicular slope = -4 (Negative reciprocal)
--------------------------------------------------------------------------------------------------------
Substitute slope into the general equation y = mx + b:
--------------------------------------------------------------------------------------------------------
y = -4x + b
--------------------------------------------------------------------------------------------------------
Find y-intercept:
--------------------------------------------------------------------------------------------------------
at point (-2, -6)
-6 = -4(-2) + b
-6 = 8 + b
b = -6 - 8
b = -14
--------------------------------------------------------------------------------------------------------
Substitute b = -14 into the equation:
--------------------------------------------------------------------------------------------------------
y = -4x + b
y = -4x - 14
--------------------------------------------------------------------------------------------------------
Equation:
--------------------------------------------------------------------------------------------------------
y = -4x - 14
y + 6 = -4x - 8 \\add 6 to both sides
y + 6 = -4(x + 2) \\Take out common factor -4
--------------------------------------------------------------------------------------------------------
Answer: y + 6 = -4(x + 2) (Answer D)

Answer:
Hi there!
Your answers are:
<h2><u>1. 21</u></h2><h2 /><h2><u>1. </u><u>1</u><u>2</u></h2>
Step-by-step explanation:
1. The derivative of 2x^2 +x -1 is equal to <u>4</u><u>x</u><u>+</u><u>1</u>
Now, plug in x= 5 into 4x+ 1
4(5) +1
20+1
21
2. The derivative of 12x -6 is equal to 12
that means:
f(x) = 12
f(x) = 12AND
f(x) = 12ANDf(3) = 12
<u>Hope</u><u> </u><u>this </u><u>makes</u><u> </u><u>sense</u><u>!</u><u> </u><u>(</u><u>updated</u><u>)</u>
To determine the answer, we need to express the fractions into its decimal counterparts. 3/5 is equal to 0.6 therefore it is closest to 0.5 while 1/10 is equal to 0.1 therefore it is the last option. Hope this answers the question. Have a nice day.
They answer is 200 it's not hard just split 400 in half
-20%
Basically, we are trying to find the change from 30 to 24 in terms of percent. We do this in three steps:
1) Find the difference between 30 and 24 as a number.
2) Divide the result from Step 1 by the starting number 30.
3) Multiply the result from Step 2 by 100 to get it in terms of percent.
The three steps above can be made into a formula. Thus, to find the percent change from 30 to 24, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 30, and Y is the ending number 24 that it changed to. When we enter these numbers into the formula, we get:
((24-30)/30)*100 = -20.00%
Thus, the answer to the question "What is the Percent Change from 30 to 24?" is:
-20.00%
