Answer: The First one isn't valid

               The second one is equal to 9

Answer:

Step-by-step explanation:

Substitute 8 for x

3(8) - 1

Solve:

3 x 8 = 24

24 - 1 = 23

Next, substitute for x in the inequality with the answer you just made. See if it's true.

23 \leq 2

The inequality is NOT TRUE

Same thing for the next one

1/2(8) + 5

Solve:

1/2 x 8 = 4

4 + 5 = 9

Substitute for x in the inequality with the answer you just made. See if it's true.

9 > 2

This inequality is TRUE

Hope this helps!!!

Solve the system of linear equations using elimination.
N76 [4]

Answer:

C (-2,1)

Step-by-step explanation:

−2x − y = 3 (1)

−9x − y = 17 (2)

(1) y = -2x - 3

(2) y = -9x - 17

-2x - 3 = -9x - 17

7x = -14

x = -2

y = -2(-2) - 3

y = 4 - 3

y = 1

Match the integrals with the type of coordinates which make them the easiest to do.
WARRIOR [948]

Answer:

1. C. cylindrical coordinates

2 A. spherical coordinates

3. A. spherical coordinates

4. D. Cartesian coordinates

5  B. polar coordinates

Step-by-step explanation:

USE THE BOUNDARY INTERVALS TO IDENTIFY

1. ∭E dV where E is:  

x^2 + y^2 + z^2<= 4, x>= 0, y>= 0, z>= 0  -- This is A CYLINDRICAL COORDINATES SINCE x>= 0, y>= 0, z>= 0

2. ∭E z^2 dV where E is:  

-2 <= z <= 2,1 <= x^ 2 + y^2 <= 2 This is A SPHERICAL COORDINATES

3. ∭E z dV where E is:

1 <= x <= 2, 3<= y <= 4,5 <= z <= 6 -- This is A SPHERICAL COORDINATES

4. ∫10∫y^20 1/x dx  ---- This is A CARTESIAN COORDINATES

5. ∬D 1/x^2 + y^2 dA where D is: x^2 + y^2 <=4  This is A POLAR COORDINATES
