Answer: m=1
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
Where
y2=12
y1=9
x2=6
x1=3
so plug in your values in the slop formula:
m=(12-9)/(6-3)
=3/3
=1
Slope-intercept form is y=mx+b
m is slope and b is y-intercept.
So, if you have -5x-3y=3
Make it into y=something
So, -3y=3+5x
y= -3/3 + 5/-3 x
y= -1 - 5/3 x
Same as the first one in your pic.
Answer:
4.5 ft^3
Step-by-step explanation:
note to convert 18 in. to feet = 1.5 feet
divide the length value by 12
So the mark up is 23,000-19,700 = 3,300
To figure of what the percent of markup is based on the SELLING price:
3,300/23,000 = x/100; now cross multiply and you have:
23,000x = 3,300(100)
23,000x = 330,000; isolate x by dividing both sides by 23,000, and you get x= 14.35
To check your work multiply 23,000 x 0.1435 = 3000.05, which was the approximate amount of markup
