Answer:
80¢\lb.; 58 667\1000 ft.\sec.
Step-by-step explanation:
Divide the cost by three; multiply 40 by 1.466675.
To get slope-intercept form we have to multiply x-1 by -4 and simplify it then
y=12+(x-1)(-4)
y=12+x*(-4)-1*(-4)
y=12-4x+4
y=-4x+16 - its the result
Answer:
- 2, 0 )
Step-by-step explanation:
Given the 2 equations
y = - 2x - 4 → (1)
y = 2x + 4 → (2)
Substitute y = - 2x - 4 into (2)
- 2x - 4 = 2x + 4 ( subtract 2x from both sides )
- 4x - 4 = 4 ( add 4 to both sides )
- 4x = 8 ( divide both sides by - 4 )
x = - 2
Substitute x = - 2 into (2) for corresponding value of y
y = 2(- 2) + 4 = - 4 + 4 = 0
Solution is (- 2, 0 )

Answer:
y = -1/2 x - 5
Step-by-step explanation:
first find slope of the line.
since it is parallel the slope is the same.
0-2 / 4-0 = -1/2
then use the slope and the point given to find the equation.
y + 3 = -1/2 (x +4)
y + 3 = -1/2x -4/2
y + 3 = -1/2x - 2
y = - 1/2 x - 5
