Answer:
(2,6)
Step-by-step explanation:
y = 2x + 2
Y = 3x
2x+2=3x
2x-3x+2=0
-x+2=0
-x=-2
x=2
y=3(2)=6
It is exponentially each time you are dividing by 4/3
Answer:
<h3>The solution is 480 bricks.</h3>
Step-by-step explanation:
We are given that number of rows of bricks in a wall = 15 rows.
Number of bricks in a row = 32 bricks.
In order to find the total number of bricks, we need to multiply number of rows with number of bricks in a row.
Total number of bricks in 15 rows = 15 × 32 = 480 bricks.
Therefore, will Chin-li will need 480 bricks.
<h3>The solution is 480 bricks.</h3>
Answer:
x = - 6 ± 
Step-by-step explanation:
Given
x² + 12x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = 1 + 36
(x + 6)² = 37 ( take the square root of both sides )
x + 6 = ± ( subtract 6 from both sides )
x = - 6 ± ← exact solutions
