The x intercept is when the line passes through the x axis , the only time that happens is when y=0
the y intercept is when the line passes through the y axis, the only time that happens is when x=0
so to solve for them, set the other coortinate to zero so
x intercept is when y=0 so set y to zero and solve for x
0-1/4x=-1/2
-1/4x=-1/2
multiply both sides by -4/1
x=2
the x intercept is (2,0)
the y intercept is when x=0 so set x to zero
y-1/4(0)=-1/2
y=-1/2
the y intercept is (0,-1/2)
the x itnercept=(2,0)
the y intercept=(0,-1/2)
So will be 5+5 + 2sqrt2 +2sqrt2 = 10 + 3 +3 = 16 rounded
hope helped
Best Answer: Bill's time to do the whole job, B
Jeff's time, B + 5
time they actually work, 6.
6/B + 6/(B+5) = 1
6(B+5) + 6B = B(B+5)
6B + 30 + 6B = B² + 5B
B² - 7B - 30 = 0
(B - 10)(B + 3) = 0
B = 10 or B = -3, and we reject the negative solution.
the equation is based on adding the fractions of the whole job each does. if Bill takes B hours to do the whole thing and works 6, he does 6/B of the job. similarly for Jeff.
in the 2nd problem,
a = time of experienced accountant
2a = time of new accountant
10 = time each actually works
10/a + 10/(2a) = 1 ........ multiply all by a
10 + 5 = a
a = 15 hr.
the answer is three digits because the answer is 157.136
Ur answer would be: 3/4. In decimal form it would be 0.75.
