Answer:

Yes, because P = 2x +2(12)

Step-by-step explanation:

As the formula for perimeter is 2(L+B).

Let L=x=18

B=12

Then, perimeter, P=2(18+12) = 2(30) = 60

Hence, we get the perimeter as 60 units.

kenny6666 [7]

Answer:

y = - 2x + 18

Step-by-step explanation:

Step 1:

y = mx + b          Slope Intercept Form

Step 2:

y = - 2x + b         Input Slope Value

Step 3:

0 = - 2 ( 9 ) + b           Input x and y values

Step 4:

0 = - 18 + b        Multiply

Step 5:

b = 18          Add 18 on both sides

Answer:

y = - 2x + 18

Hope This Helps :)

olchik [2.2K]

Answer:

8 2/5 inches!

Step-by-step explanation:

The lighthouse is 120 feet, and 4 inches of height on the model equals 50 feet of height on the lighthouse. 100 divided by 50 = 2, and 4 multiplied by 2 is 8. 20 divided by 50 = 2/5, so the answer is 8 2/5 inches. :)

Stella [2.4K]

Answer:

see the procedure

Step-by-step explanation:

Looking at the graph we have

The graph represent a  vertical parabola open upward

The vertex is a minimum

The vertex is the point (-4,-3)

The domain is the interval -----> (-∞,∞)

The Domain is all real numbers

The range is the interval ----> [-3,∞)

y\geq -3

The range is all real numbers greater than or equal to -3

The graph is increasing in the interval (-4,∞)

The graph is decreasing in the interval (-∞,-4)

The minimum of the graph is y=-3 occurs at x=-4
