Both slopes have the same value which is 7.5.

To compute for the slope we will use this formula:
   m = y^2 - y^1 over x^2 - x^1

For the first slope, the points are<span> (4, 30) and (12, 90). Substitute and simplify.
   m = (90 - 30) over (12 - 4)
   m = 7.5

For the second slope, the points are </span><span>(4, 30) and (10, 75). Same with the above computation.
   m = (75 - 30) over (10 - 4)
   m = 7.5

Since the relationship is linear, the slope does not change. </span>

Answer:

∴ opposite side = √108

Step-by-step explanation:

Here hypotenuse = 12 ft

It is a right angled triangle.

here triangle ABC in which ∠ C = 60°

 ∠B = 90°

so ∠A = 180° -( 90 +60)

           = 180 - 150

            = 30°

cos 60° = adjacent side ÷ hypotenuse

  \frac{1}{2} = x ÷ 12

\frac{1}{2} = \frac{x}{12}

12 = 2 x

∴ x = 6

adjacent side = 6

hypotenuse ² = adjacent side² + opposite side²

 12²  = 6² + opposite side²

144 - 36 = opposite side ²

108 = opposite side²

∴ opposite side = √108

Which is a simplified form of the expression -2b – 3(2b + 1)?
lakkis [162]

Answer:

C

Step-by-step explanation:

We need to use the distributive property to expand this.

The property is:

a(b+c) = ab + ac

So, the part " -3(2b+1) " will becomes:

-3(2b+1) = (-3)(2b) + (-3)(1) = -6b - 3

So, the problem becomes:

-2b -3(2b+1) = -2b -6b -3

Now, we add like terms:

-2b - 6b - 3

(-2-6)b - 3

-8b - 3

This is the correct answer, answer choice C
