Step-by-step explanation:
P = 2l + 2w --> w = 1/2·P - l = 1/2·42 - 15 = 6 feet
Answer:
y = - 8x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 8x + 5 ← is in slope- intercept form
with slope m = - 8
Parallel lines have equal slopes, thus
y = - 8x + c ← is the partial equation of the parallel line
To find c substitute (1, - 2) into the partial equation
- 2 = - 8 + c ⇒ c = - 2 + 8 = 6
y = - 8x + 6 ← equation of parallel line
3x-1/2 - 2(4+3x)/13 = 2
distribute
3x -1/2 -8/13 -6x/13 =2
combine like terms
3x-6x/13 -1/2 -8/13 =2
multiply by 26 to get rid of the fractions (2*13)
26*(3x-6x/13 -1/2 -8/13) =2*26
78x - 12x -13 -16 = 52
66x -29 =52
add 29 to each side
66x =81
x = 81/66
divide top and bottom by 3
x=27/22
x = 1 5/22
I believe the answer is 13, sorry if it is wrong
