Solution to the system of linear equations is (5/3, -14/3)
Step-by-step explanation:
- Step 1: The system of linear equations are
8x + 2y = 4 ------ (1)
16x - y = 18 ------ (2)
- Step 2: Multiply eq(2) by 2 to make coefficients of y equal
8x + 2y = 4
16x - 2y = 36
- Step 3: Add the two equations
⇒ 24x = 40
⇒ x = 40/24 = 5/3
- Step 4: Find the value of y
⇒ 8 × 5/3 + 2y = 4
⇒ 40/3 + 2y = 4
⇒ 2y = 4 - 40/3 = -28/3
⇒ y = -14/3
Answer:
0a = 0
Step-by-step explanation:
Expand
8a + 32 + 4 = 36 + 8a
Rearrange equation
8a - 8a = 36 - 32 - 4
0a = 0
3p + 7c = p....subtract 3p from both sides
7c = p - 3p
7c = - 2p ....now divide both sides by 7
c = -2/7p <==
Answer:
4 maybe I don't understand what or how to do this but W is similar to M. I don't really know.
Step-by-step explanation:
Answer:
Using trigonometric ratio:
From the given statement:
and sin < 0
⇒ lies in the 3rd quadrant.
then;
Using trigonometry identities:
Substitute the given values we have;
Since, sin < 0
⇒
now, find :
Substitute the given values we have;
Therefore, the exact value of:
(a)
(b)
