Number 7 is the x axis 11 is (4,2)
Answer:
Step-by-step explanation:
x + y = 4 ---------------(i)
x = 4-y
7x + 9y = 42 -----------(ii)
Plug in x = 4-y in equ (ii)
7*(4 - y) + 9y = 42
28 - 7y +9y = 42
28 + 2y = 42
2y = 42 - 28
2y = 14
y = 14/2
y = 7
x = 4 - y
x = 4 - 7
x = -3
Answer:
2x +3y=1⇒equation 1
3x=2y+8
3x-2y=8⇒equation 2
by elimination method,
2x+3y=1 ×2
3x-2y=8 ×3
4x+6y=2
9x-6y=24
cut 6y and -6y
4x+6y=2
9x-6y=24
---------------
13x+0=26
13x=26
x=26/13
x=2
substitute x=2 in equation 1
2(2)+3y=1
4+3y=1
3y=1-4
3y=-3
y=-3/3
y=-1
therefore, x=2 and y=-1
hope it helps u!
Given:
In triangle ABC, AB = 30, BC = 16, AC = 34 and measure of angle B is 90 degrees.
To find:
The value of Sine of angle A.
Solution:
In a right angle triangle,
In the given triangle ABC,
Therefore, the correct option is A.
This means that point P lies on GK where the ratio between the length of GP to the length of PK is:
GP/PK = 2/3
To better understand this, assume that the length of GK is 5 cm. Applying the given ratio, we will find that:
GP = 2 cm and PK = 3cm
