The answer is 26. I got this answer by plotting out the points on a coordinate plane and counting the perimeter around the shape to get 26. Hope this helps! :)

Answer:

Step-by-step explanation:

Firstly, plot the points on graph paper which you can find on the internet. The first number in the ordered pair, (the ones in parenthesis), is the x coordinate. The other number is the y coordinate. Put these onto a graph which is attached. The perimeter is 26.

To ride a roller coaster, a visitor must not be less than 56 inches tall.

Lubov Fominskaja [6]

Answer: Required expression would be $h\geq 56$

Step-by-step explanation:

Since we have given that

To ride a roller coaster, a visitor must not be less than 56 inches tall.

Let h be the height of a visitor able to ride.

It means, h must not less than 56 inches.

Mathematically, it is expressed as

$h\geq 56$

Hence, required expression would be $h\geq 56$

Answer: Choice D) Slopes are the same

----------------------------------------

Explanation:

The graph of f(x) is a straight line through the two points (0,3) and (1,1). Those points are the left and right points respectively.

Start at (0,3). To get to (0,1), we move 2 units down and 1 unit to the right. Think of the "2 units down" as a "rise of -2". Negative rise means you're really falling.

So the slope of f(x) is
slope = rise/run = -2/1 = -2
slope = -2

The slope of g(x) is also -2

Note how y = -2x-5 is in y = mx+b form
we see that m = -2 is the slope
b = -5 is the y intercept

So that shows why the two functions have the same slope.

The graph of g(x) = -x^2 is shifted 3 units left and 1 unit up. If this new graph is f(x), then what is the value of f(-1.5)

$\bf \bullet \textit{ horizontal shift by }\frac{{{ C}}}{{{ B}}}\\

with that template in mind, let's see.

to the left by 3 units, C = +3
up by 1 unit, D = 1

$\bf g(x)=-x^2\\\\\\ g(x)=-1(1x+\stackrel{C}{0})^2+\stackrel{D}{0}\implies g(x)=-1(1x+3)^2+1
\\\\\\
g(x)=-(x+3)^2+1\impliedby f(x)\qquad \qquad f(-1.5)=-[(-1.5)+3]^2+1$

and surely you know how much that is.
