Answer: y = - 9
Step-by-step explanation:
Two lines are said to be perpendicular if the product of their slope = 1 , that is , if the slope of the first line is and the slope of the second line is , then = , that is :
X = -1
The line given is ; 2x + y = - 4
Make y the subject of the formula so that the equation will be in slope - intercept form ; y = mx + c
that is
y = -2x - 4
comparing with the equation of line y = mx + c , it shows that = -2
Since the second line is perpendicular to this line , it means =
That is
=
Using the formula y - = m ( x - ) to find the equation of the line
= -8
= 2
substituting into the equation
y - (-8) = ( x - 2)
y + 8 = ( x- 2)
2(y+8) = x - 2
2y + 16 = x - 2
2y = x - 2 - 16
2y = x - 18
y = - 18/2
y = - 9

Answer:
20 % decay
Step-by-step explanation:
Exponential equations are in the form
y = a * b^x
a is the initial value
b is the growth or decay
b>1 is growth b-1 rate of growth
b <1 decay 1-b rate of decay
1-.8 = .2
Change to decimal form
20 % decay
The compound inequality that shows the range of number is:
<u><em>Explanation</em></u>
Isabella is thinking of a number .
Given that, 6 less than 6 times her number is between 24 and 48.
So, 6 less than 6 times the number means:
So, the inequality will be....
<em>That means, the number that Isabella might be thinking of will be in between 5 and 9. </em>
So, the compound inequality that shows the range of number is:
