Answer:
(2, 4)
<u>x = 2</u>
<u>y = 4.</u>
Step-by-step explanation:
To find the solution to the system of equations, we can simply set the two equations equal to each other as shown:
x + 2 = 3x - 2
Subtract 'x' from both sides:
2 = 2x - 2
Add '2' to both sides:
4 = 2x
x = 2.
Plug this value for 'x' into an equation to solve for 'y':
y = (2) + 2
y = 4.
Therefore, the solution to the system is (2, 4).
Answer:
1/4, 3 3/4, 5 1/4
Step-by-step explanation:
Solving for a[n-1], we get ...
a[n-1] = n^2 -a[n]
Then ...
a[4] = 5^2 -a[5] = 25 -14 1/4 = 10 3/4
a[3] = 4^2 -a[4] = 16 -10 3/4 = 5 1/4
a[2] = 3^2 -a[3] = 9 -5 1/4 = 3 3/4
a[1] = 2^2 -a[2] = 4 -3 3/4 = 1/4
Then the first three terms are a[1], a[2], and a[3]:
1/4, 3 3/4, 5 1/4
Answer:
616 cm²
Step-by-step explanation:
To find the area of a circle you use the formula A = π · r²
So we know that the diameter is 28 cm, to find the radius we would divide this in half, because d = 2r, giving us 14. Now we can do 14² which is 196, and then times that by pi or in this case 22/7.
196 × (22/7) = 616
Answer:
Step-by-step explanation:
6Sin² Ф + 11Sin Ф + 4 = 0
Product = 6*4 = 24
Sum =11
Factors = 8 , 3 {8*3 = 24 & 8+3 = 11}
6Sin² Ф + 8Sin Ф + 3 sin Ф + 4 = 0
2Sin Ф ( 3Sin Ф + 4) + (3Sin Ф + 4) = 0
( 3Sin Ф + 4) (2Sin Ф + 1) = 0
3Sin Ф + 4 = 0 ; 2Sin Ф + 1 = 0
3Sin Ф = -4 ; 2Sin Ф = -1
Sin Ф = -4/3 ; Sin Ф = -1/2
Sin Ф = -4/3 , -1/2
