What is the solution to the following system densations?
givi [52]

Answer:

D. (2, 1)

Step-by-step explanation:

Given:

y = 6x - 11

-2x - 3y = -7

Required:

Find the solution.

Solution:

y = 6x - 11 ---› eqn. 1

-2x - 3y = -7 ----› eqn 2

Substitute y = (6x - 11) into equation 2.

-2x - 3(6x - 11) = -7

-2x - 18x + 33 = -7

-20x + 33 = -7

Subtract 33 from each side

-20x = -7 - 33

-20x = -40

Divide both sides by -20

x = -40/-20

x = 2

Substitute x = 2 into equation 1.

y = 6x - 11 ---› eqn. 1

y = 6(2) - 11

y = 12 - 11

y = 1

The solution is very (2, 1)

C) Consider the time 3:40pm where the initial side is the hour hand and terminal side is the
Stells [14]

Answer:

  • 210 degrees
  • -150 degrees

Step-by-step explanation:

When the time is 3:40pm

  • The Initial Side (hour hand) is at 3.
  • Terminal Side (Minute hand) is at 8.

(a)The angle between the two hands in standard position is drawn and attached below.

(b)Now, each hour = 30 degrees

Therefore, the angle between 3 and 8 in an anticlockwise movement

= 7 X 30 =210 degrees

Stating the angle as a negative angle, we have:

210^\circ-360^\circ=-150^\circ\\$The angle as a negative angle is -150^\circ
