72x = 61

x = 61/72

x = 84.72%

100 - 84.72 = 15.28

Option A.

Consider the rule y = 5x + 7.

maksim [4K]

Answer:

see below

Step-by-step explanation:

Consider the rule y = 5x + 7.

a. How many tiles are in Figure 0?

In figure 0, we let x=0

y = 5*0+7 = 0+7 = 7

b. Which figure has 37 tiles?

This means y = 37

37 = 5x+7

Subtract 7 from each side

37-7 = 5x+7-7

30 = 5x

Divide by 5

30/5 = 5x/5

6 =x

Figure 6 has 37 tiles

c. In the equation y = mx + b, what do the letters m and b represent?

m is the slope or how much it is increasing each time x increases by 1 and b is how much we start with when x =0

Find the focus. y= -1/12 (x)² - 6

Answer:

$\Large \boxed{\sf\ \ (0,-9) \ \ }$

Step-by-step explanation:

Hello,

We know that when the parabola equation is

$y=a(x-h)^2+k$

the vertex is (h,k) and the focus is

$(h,k+\dfrac{1}{4a})$

Here, the equation is

$y=-\dfrac{1}{12}x^2-6$

so

$a=-\dfrac{1}{12}\\\\h = 0\\\\k =-6$

So,

$k+\dfrac{1}{4a}=-6-\dfrac{12}{4}=-6-3=-9$

Then, the focus is

$\large \boxed{\sf\ \ (0,-9) \ \ }$

I attached the graph, included the focus so that you can see it :-)

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Answer:

Obtuse, scalene.

Step-by-step explanation:

In ΔSVU, one angle is 120° which is obtuse angle.

So, ΔSVU is a obtuse triangle.

All the sides have different measurements. So, It is a Scalene triangle.
