What is the -x intercept and y-intercept of y=-2x+4

1 answer:

4 0

To find x intercept, you must set the y value equal to zero
0= -2x+4
Subtract 4
-4= -2x
Divide by -2
x=-4/-2= 4/2= 2
The x intercept is 2

To find the y intercept, you must set the x value equal to zero
y= -2(0)+4
y=4
The y intercept is 4

30 men repair a road in 56 days by working 6 hours daily. in how many days 45 men will repair same road by working 7 hours daily

zepelin [54]

Answer:

Case1:

Men : 30

Work : 1

Time (day×hr): 56×6 = 336 hr.

Case2:

Men : let it be m men.

Work: 1

Time: 45×7 = 315 hr.

Work being constant in both cases, men and time are in inverse proportion i.e, more men take less time.

Product of men and time is constant in both cases.

Therefore, 30×336=m×315

Or, 30×336/315 = m

Or, m = 32.

Hence, required number of men is 32.

How many DVDs. A small independent movie company determines the profit P for producing n DVD copies of a recent release is P = −

Softa [21]

The company should produce "85" DVD's to maximize the profit.

According to the question,

The profit P for producing n DVD copies are

$P=-0.02n^2+3.4n -16$

Let,

The number of units be "n".

Now,

To find the minimize profit,

→ $P'(n) = 0$

→ $-0.04n+3.4=0$

By substracting "3.4" from both the sides, we get

→ $-0.04n+3.4-3.4=-3.4$

→ $-0.04n = -3.4$

→ $n = \frac{-3.4}{-0.04}$

→ $n = 85$

Thus the answer above is right.
