What is the length of segment CD question mark

Mathematics
1 answer:
blagie [28]4 years ago
8 0

Answer:

CD = two square root of 10 end square root

Step-by-step explanation:

To find the length of a segment, use the distance formula. Substitute the order pairs for the endpoints of the segment. CD has the end points (-7, -4) and (-1, -2).

d = \sqrt{(y_2-y_1)^2 + (x_2-x_1)^2} \\\\d = \sqrt{(-4--2)^2 + (-7--1)^2} \\\\d = \sqrt{-2^2 + -6^2}\\\\d = \sqrt{4 + 36}\\\\d=\sqrt {40} = 2\sqrt{10}

Determine wether the equation represents a direct variation. If it does find the constant of variation. 2y=5x+1
svp [43]

Answer:

No, the equation does not represent a direct variation.

Step-by-step explanation:

The answer is immediately evident:  NO.  The reason for this is that no direct variation equation includes a vertical intercept.

Here 2y = 5x + 1 becoems y = (5/2)x + 1/2; the y-intercept 1/2 is problematic.

If we were to drop the constant 1, then 2y = 5x, or y = (5/2)x; this represents direct variation with the constant of proportionality 5/2.

You want to buy some clothing from an online retailer. The shirts cost $9 each and the
alisha [4.7K]

The answer is $73

Explanation:

since you are buying five shirts for nine dollars each you would need to do 5x9 which equals 45. Now you need to do 12x2 since you bought two pairs of pants for twelve dollars each. 12x2 equals 24. Now you need to add 24 and 45 to see what your price is. 24+45=69. Now add on four dollars for shipping and handling and you will have $73 dollars. Hope this helps!
