Answer:
y = 1/4x - - 9
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
8y - 2x = -72
<u>Step 2: Rewrite</u>
<em>Find slope-intercept form</em>
- Add 2x on both sides: 8y = 2x - 72
- Divide 8 on both sides: y = 1/4x - - 9
I think it is 156 but I don't know for sure.
I hope this helps!
Slope-intercept form:
y = mx + b "m" is the slope, "b" is the y-intercept
For lines to be perpendicular, their slopes have to be the opposite/negative reciprocal (flipped sign and number)
For example:
slope is 2
perpendicular line's slope is -1/2
slope is -3/4
perpendicular line's slope is 4/3
#1: The slopes are the same, meaning they are parallel lines
#2: First isolate the "y" in the first equation
-4x + 5y = -5
5y = -5 + 4x
y = -1 + 4/5x They are not perpendicular because the slopes are 4/5 and -4/5
#3: Isolate "y" in the second equation
8y = 3x - 32
y = 3/8x - 4 They are perpendicular
#4: Isolate "y" is the 1st equation
10y = -9x
y = -9/10x They are parallel lines
The 3rd choice is your answer
Answer:
<h2>The answer is 1</h2>
Step-by-step explanation:
First of all transform the expression using trigonometric identities
That's
So we have
Reduce the expression with tan x
We have
Reduce the expression with cos x
That's
Reduce the expression with sin x
We have
We have the final answer as
<h3>1</h3>
