Answer:

b)

x =  \frac{15}{4}

Step-by-step explanation:

b) set up equations so they are equal to each other,

2x - 2 =  - 3x + 12

5x = 14

x = \frac{14}{5}

this is when f(x)=g(x) so our approximation was close.

c)solving it graphically is nearly impossible because the solution can be any value around the intersection. only way to be sure is to solve it symbolically.

A brick has a volume of 2,300 mL and a mass of 3.4 kg. what is the density of the brick
charle [14.2K]
The formula of a density is
p = M/V
where p is a density, M is a mass and V is a volume.
Given M = 3.4 kg and V = 2,300 mL or 2,300 cm<span>³, therefore
</span>p = 3.4 kg / 2,300 cm³ = 1.48 x 10⁻³ kg/cm³
