6:36 is what i would guess.
Answer:
(-111)
Step-by-step explanation:
25x+ the diameter of a rectangle
After reading through the story problem, I ended up with this equation:
(35-2)(x+.5) =?
or
(35-2)(10+.5)=?
Explanation:
He sells 35 books for usual weeks. Since he is selling his books at $.50 more his average number of copies decreased by 2.
35-2 = 33
Next, we know that he adds $.50 for his price for each copy. If the price is $10 per copy than it looks like this:
$10+$.50= 10+.5
or if the price is not $10 it will be
$x+$.5= x+.5
Given the equations:
Let's determine if the lines are parallel or perpendicular.
Rewrite both equations in slope-intercept form:
y = mx + b
Where m is the slope.
Rewrite each equation for y.
• Equation 1:
• Equation 2:
Therefore, we have both equations in slope-intercept form:
• The slope of equation 1 is: -7/4
,
• The slope of equation 2 is: -4/7
Parallel lines have equal slopes.
Perpendicular lines have slopes that are the negative reciprocal of each other.
Since both slopes are neither equal nor negative reciprocals, then both lines are neither parallel nor perpendicular.
• ANSWER:
Neither
