Answer:

C and D are unchanged, but E increases.

Step-by-step explanation:

Given equation of circle

x^2+y^2+Cx+Dy+E=0

But we know that general equation of circle is with center at (h,k)

x^2 + y^2 -2hx -2ky + (h^2 + k^2 – r^2) = 0

Comparing both equations we get,

C = -2hx

D = -2ky

As in the given question we are not changing the coordinates of center so C and D will remain unchanged.  

It also gives us

E = (h^2 + k^2 – r^2)

Decreasing r means that a lesser quantity will be subtracted from h^2 + k^2 which will increase the value of E.

PLEASE HELP!!!!!!!!!!!!!!!!

Answer:

<h2>1. subtract 3x, subtract 4, divide by -4</h2><h2 /><h2>2. add x</h2>

Step-by-step explanation:

1 + 3x = -x + 4.

subtract 3x

1 = -4x + 4

subtract 4

-3 = -4x

divide by -4

(-3)/(-4) = (4x)/(-4)  ⇌ x = 3/4

-x + 6 = 5 - 3x

subtract 5

-x + 1 = - 3x

add x

1 = -2x

0.10d + 0.25q = 3.55
q = d + 3

0.10d + 0.25(d + 3) = 3.55
0.10d + 0.25d + 0.75 = 3.55
0.10d + 0.25d = 3.55 - 0.75
0.35d = 2.80
d = 2.80/0.35
d = 8.....8 dimes

q = d + 3
q = 8 + 3
q = 11 <=== 11 quarters

4 1/6 + 5 2/3Enter your answer as a mixed number in simplest form
galina1969 [7]

Answer:

Step-by-step explanation:

First, change the mixed numbers into improper fractions:

5 2/3 = 17/3

Then, find the common denominator:

41/6 + 17/3=

LCM = 6

17/3 *2 = 34/6

41/6 + 34/6

Last, Add

25/6  or

12 1/2

Hope this helps!
