 The arc mCAD is 288.

Given: DAB and DCB are right angles; <span>BDC = 54°
Required: arc </span><span>mCAD
Solution:
 (2 x 54</span>°) + (2 x 54°) + (2 x 36°<span>) = 288
 
Note: in getting 36</span>°, deduct 54° and 90° (right angle) from 180° (which is the total degrees inside a triangle)
   = 180° - 54° - 90°
   = 36° - this is the angle CBD or angle ABD

marissa [1.9K]

Answer:

Tara has traveled 8 times

Step-by-step explanation:

a = April

T = Tara

d = Denise

so in terms of t:

t= t

a = 4t

d = 0.5t

add then together

5.5t = 44

divide by 5.5

The equation of the graphed line in point-slope form and it’s equation in slope-intercept form is (-2,3)(3,0)
Murljashka [212]

Answer:

y = -9/5x + 9/5

Step-by-step explanation:

From this points, we can determine the slope and the y-intercept.

First, we do:   y/x  -  y1/x1

=> 0/3 - (3 - 2)

=> 0-3/ 3 + 2

=> -3/5

So the slope of the equation is -3/5.

The equation is: y = mx + b

In this equation "m" = slope.

=>  b = constant

Now we take the x and y points from the above numbers.

=> Let's take 3 as x and 0 as y.

=> 0 = -3/5 *3 + b

=> 0 = -9/5 + b

=> Take the -9/5 to the other side

=> 9/5 = b

So, the constant number which is not multiplied by the x is 9/5

Now, our equation looks like:

y = -9/5x + 9/5

If you have any doubts about this question, ask me the comments and I will answer it as soon as possible.

Write your answer in the form y=my+b
CaHeK987 [17]

Answer:

y= -2x+18

Step-by-step explanation:

1. The secant line is a line that passes through 2 points in the function.

2. Determine the y values for x=-6 and x=3 by plugging the x values into the x^2 + x function. This yields 30 for x=-6 and 12 for x=3.

3. Find the slope by calculating the rise over the run, represented by the equation (y2 - y1)/(x2-x1). Plugging in the numbers we get (12-30) divided by (3 -(-6)). This gives you a slope equation of -18/9 (subtracting a negative yields a positive), which simplifies to -2.

4. Now that you have your slope m, apply it backwards from x=3 (x=2 yields 14 for y, 1 yields 16, 0 yields 18). Once you arrive at x=0, the y value is your y-intercept.

5. Put the y-intercept b into the equation y= mx+b, and you come out with y= -2x + 18!
