1 answer:
Shalnov [3]3 years ago
5 0

Answer:

3.) 5=b

4.) x=-4

5.) n > 0

6.) x > -1

7.) v > -3

8.) a > 1

Step-by-step explanation:

3.) 6(5-b)=35-7b

30-6b=35-7b

+6b on each side

30=35-b

-35 on each side

-5=-b

5=b

4.) 15+7x=2(x-5)+5

15+7x=2x-10+5

15+7x=2x-5

-2x from each side

15+5x=-5

-15 from each side

5x=-20

÷ each side by 5

x=-4

5.) 15+8n>-3(-5+3n)

15+8n>15-9n

+9n to each side

15+17n>15

-15 each side

17n>0

÷ each side by 17

n>0

6.) 4(8x+8)+5>8x+13

32x+32+5>8x+13

32x+37>8x+13

-8x each side

24x+37>13

-37 each side

24x>-24

÷ by 24

x>-1

7.) 7(5v+6)>-39+8v

35v+42>-39+8v

-8v each side

27v+42>-39

-42 each side

27v>-81

÷ by 27

v>-3

8.) -7(-5+5a)+5<7a-2

35-35a+5<7a-2

40-35a<7a-2

-7a each side

40-42a<-2

-40 each side

-42a<-42

÷ by -42

a>1

Hope this helps, i dont know how to post a pic on here so you still have to graph 5-8.

Samantha worked 40.5 hrs this week. she makes 9.50 per hour. how much money did she earn this week?
SashulF [63]
To find out how much money Samantha earned this week, we just need to multiply the rate of money she earns per hour by the amount of hours she worked.

9.50 * 40.5 = 384.75

Samantha earned $384.75 this week.
Hope that helped! =)

Find the volume of the solid generated by revolving the region bounded by the lines and curves about the x-axis. y = x, y =1, x
liraira [26]

Answer:

The volume is: V = \frac{\pi}{3} cubic units

Step-by-step explanation:

Volume of a solid:

The volume of a solid, given by the function f(x), over an interval between a and b, is given by:

V = \pi \int_{a}^{b} (f(x))^2 dx

y = x, y =1, x = 0

This means that the upper function is y = 1, and the lower function is y = x. So

f(x) = (1 - x)

The lower limit of integration is x = 0.

The upper limit is y = x when y = 1, so x = 1.

Then

V = \pi \int_{a}^{b} (f(x))^2 dx

V = \pi \int_{0}^{1} (1-x)^2 dx

V = \pi \int_{0}^{1} (1-2x+x^2) dx

V = \pi (x-x^2+\frac{x^3}{3})|_{0}^{1} dx

V = \pi(1 - (1^2) + \frac{1^3}{3})

V = \frac{\pi}{3}
