2. Are the expressions -5 + -2 and -5 – 2 equivalent? Why or why not? Explain and show your work.
scoray [572]

Answer:

Yes, the expressions are equivalent.

Step-by-step explanation:

Notice that -2  is defined as in additive inverse of 2, that is, 2 + -2 = 0.

and substracting 2 from 2 is also equal to zero, that is, 2 - 2 = 0.

Thus 2-2 = 2+ -2, implying -2 = + -2. Consequently, -5 + -2 = -5 -2

At 8:00 AM the temperature in colorado was -21F by 9:00 AM the temperature was 6F.what is the difference in the temperature betw
klemol [59]
Okay. So, one temperature is positive and the other one is negative. Let’s find the absolute value (distance from 0) for both numbers. -21 is 21 units away from 0 and 6 is 6 units away from 0. 21 + 6 = 27. The difference of temperature from 8 AM to 9 AM is 27 degrees.

The local radio tower is located 20 miles east and 12 miles north of Pamela's cabin. The radio tower has a 25 mile broadcast rad
pychu [463]

Answer:

x^2 +y^2 -40x -24y  -81 =0

Step-by-step explanation:

We can write the equation of a circle in the form

(x-h)^2 + (y-k)^2 = r^2

Where (h,k) is the center and r is the radius

Assuming that Pamela's cabin is the center

( x-20)^2 + (y- 12)^2 = 25^2

We want to get to general form

x^2 + y^2 + Dx + Ey + F = 0,

Distributing

x^2 -40x +400 + y^2 -24y +144 = 625

x^2 +y^2 -40x -24y +544 -625 =0

x^2 +y^2 -40x -24y  -81 =0
