3. -4x - 6
-3(x + 2) - x → ( distribute bracket by - 3)
= - 3x - 6 -x → (collect like terms)
=( - 3x - x) - 6 = - 4x - 6
4. A has the smallest value
A =( 2 - 3 ) = -1
B = 2 × 3 = 6
C = 2 + 3 = 5
D = 
A is negative while the others are all positive.
Thus A is the smallest value expression
Answer:
Simple interest = PRT/100
300 = 150 x 4 x T/100
2 x 100/4 = T
Therefore T = 50 years
Hope this helps!
Answer:
The length of DB is 8
Step-by-step explanation:
I know it doesn't look EXACTLY like the one in the diagram but I just followed the measurements provided
Y = mx + b
slope(m) = 5
(6,2)...x = 6 and y = 2
sub and find b, the y int
2 = 5(6) + b
2 = 30 + b
2 - 30 = b
-28 = b
so the equation for this line is : y = 5x - 28
y = 5x - 28.......when y = -3
-3 = 5x - 28
-3 + 28 = 5x
25 = 5x
25/5 = x
5 = x <==== ur x coordinate
