Answer:
1) 2b + 6
2) 8w - 12
3) 2b + 6 + 6x + 20
4) 9w^2 + 27 + 8 - 27
5) Sorry.
Step-by-step explanation:
y=a.(X-x1)(X-x2)
x1 and x2 are x-intercepts
x1=-3
x2=1
other points: (-1,8) and (0,5)
y=a.(x+3).(x-1)
a=-2
f(x)= -2.(x+3)(x-1)
Answer:
Answer: Density = 0.5 g/cm³
Explanation: Density is the ratio of mass per unit volume or D = m/V
D = m/V
= 6 g / 12 cm³
= 0.5 g / cm³
-10x + 5y = 15
Divide everything by 5.
-10x/5 + 5y/5 = 15/5
-2x + y = 3
So, we can imagine some values to this equality
If x = -1 and y = 1 we have
-2.(-1) + 1 = 3
2 + 1 = 3
3 = 3
Another way we can say:
-10x + 5y = 15
5y = 10x + 15
Divide everything by 5.
y = 2x + 3
So just imagine values to x, let's make 0, 1 and 2.
y = 2.0 + 3
y = 0 + 3
y = 3
y = 2.1 + 3
y = 2 + 3
y = 5
y = 2.2 + 3
y = 4 + 3
y = 7
So, when x = 0, y = 3.
When x = 1, y = 5.
When x = 2, y = 7.
