In the diagram below, what is the equation that represents the relationship between the number of triangles and the perimeter of
Marina86 [1]

Answer:

The perimeter of the figure as a function of the number of triangles is y = 6 + 4\cdot x.

Step-by-step explanation:

According to the diagram, we get the following facts:

i) For one triangle (x=1), the total perimeter is (y=2\cdot 3 + 1\cdot 4 = 10).

ii) For two triangles (x = 2), the total perimeter is (y = 2\cdot 3 +2\cdot 4 = 14)

iii) For three triangles (x = 3), the total perimeter is (y = 2\cdot 3 +3\cdot 4 = 18)

iv) For four triangles (x = 4), the total perimeter is (y = 2\cdot 3 +4\cdot 4 = 22)

From these information we conclude that the equation that determines the perimeter of the figure as a function of the number of triangles is y = 6 + 4\cdot x.

Find the slope for a line perpendicular to y= -5/3x+7
aleksley [76]

Answer:

3/5

Step-by-step explanation:

To find the slope of the given line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line y=-5/3x+7  is m = 3/5. Step 2: Use the slope to find the y-intercept.

How I can solve this
gavmur [86]

Answer:

\boxed{\textrm{B)}\qquad y>4}.

Step-by-step explanation:

We start by subtracting 1 from both sides of the second inequality:

2x > 5 \iff 2x - 1 > 5 - 1 \iff 2x - 1 > 4.

Therefore, we conclude that:

y > 2x - 1 > 4 \implies y > 4.

Therefore, every point that satisfies the system has a y-coordinate greater than 4.

Calculate the circumference. round to the nearest hundredth. 16 inches
goldenfox [79]

Given the radius is, r = 16 in,

The expression for the circumference of a circle is,

C=2\pi r

Therefore, we have,

C=2\times3.14\times16\text{ in = }100.48\text{ in}

Thus, the circumference of the circle is 100.48 in.
