Answer:

n(E) = 6

Step-by-step explanation:

That's to say that there are 6 five-digit numbers with 7 in the first place and 8 in the last place, using the digits 2, 3, 4, 7 and 8. Therefore n(E) = 6.

Sallie Woo worked these hours last week: Monday, 10; Tuesday, 8 1/4; Wednesday, 9 1/2; Thursday, 6; Friday, 8; Saturday, 5. Sall
almond37 [142]

Answer:

Her pay for the week= $ 611.325

Step-by-step explanation:

Sallie is paid $ 11.40 per hour for regular hours.

The total regular hours worked during the week are

Monday + Tuesday + Wednesday + Thursday+ friday = 8 + 8+ 8+6+8= 38 hours

She works overtime during the week

Monday + Tuesday + Wednesday = 2+ 1/4+  1 1/2=  2+ 1/4 + 3/2

= 8 +1+ 6/4=15/4 = 3 3/4 hours

Over the weekend she works five hours .

So the total pay would be

$ 11.40( 38 ) + $ 11.40( 1.5) (  15/4) + $ 11.40 ( 2) ( 5)

= 433.2 + 64.125 + 114.0

= $ 611.325

The slope of the line below is -2. Use the coordinates of the labeled point to find the point-slope equation of the line. (4, -6
r-ruslan [8.4K]

<u>Answer:</u>

The point-slope equation of the line is y = -2x +2 or 2x+y = 2

<u>Solution: </u>

Let us assume that the slope is m and the y intercept of the line is b

Hence, y=m x+b--------- (i)

y intercept means we need to find the value of y when x is 0

Here the line passes through point (4,-6) and slope m = (-2)

Now putting the point (4,-6) in equation (i) we get,

\Rightarrow-6 = m\times4 +b

\Rightarrow-6 = (-2)\times4 +b

\Rightarrow-6 = -8 +b

\Rightarrow-6+8 =b

\Rightarrow b = 2

So, the equation of the line will be will be y = -2x +2 or 2x+y = 2
