Answer: 21.
Step-by-step explanation:
Answer:
Part 1) The equation in slope intercept form is 
Step-by-step explanation:
Part 1) Write an equation in slope-intercept form for a line that passes through (3,4) (and has a y intercept of -8)
we know that
The equation of a line in slope intercept form is equal to

where
m is the slope
b is the y-intercept
we have


substitute

solve for m



therefore

X= 7 1/3
Explanation- Take 72 and subtract 50 from that giving you 22. Then take 22 and divide it by 3 to get 7.3333333333333 (repeats) or 7 1/3
Answer:
x = 2
Step-by-step explanation:
A = lw
44 = 4(3x+5)
44 = 12x + 20
24 = 12x
x = 2
