Answer:

(x-8)^2+(y+8)^2=7

Step-by-step explanation:

The equation of a circle is (x-h)^2+(y-k)^2=r^2

Substitute h, k, and r for 8, -8, and √7, respectively.

(x-(8))^2+(y-(-8))^2=(√7)^2

The two negatives in y - (-8) causes it to be a +8. Squaring √7 will make it 7.

Write an equation that expresses the following relationship: x varies directly as p and inversely as the difference between y an

dsp73

X = kp/y-c

cross multiply

xy-xc = kp

factor out the x

x(y-c) = kp

divide entire equation by x

y-c = kp/x

isolate y since we are solving for y
we do this by adding c to both sides which ultimately gives us the answer

y = kp/x + c

WhaThe factorization of x2 + 3x – 4 is modeled with algebra tiles.t is the factored form of x2 – x – 2?

Nataly [62]

Answer:

x^2 -x -2 = (x -2)(x +1)

Step-by-step explanation:

To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:

-2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1

Then these are the constants in the binomial factors:

x^2 -x -2 = (x +1)(x -2)

<em>Comment on the question</em>

The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.

The correct answer are

Sue interest : 169.6061952

Bill interest: 189.9131472

B. Bill will get more interest then sue

Explain

Sue principal balance p= 2300

Interest for 3 years so t= 3

Interest is compounded yearly n= 1

R= 2.4%

A= 2300(1+2.4/100)^3 = 2300(1+0.024)^3 = 2300 x (1.024)^3 = 2469.6061952

Interest for 3 year is A-p= 2469.6061952 -2300

169.6061952

Bill principle p= 1800

Interest for 3 years t= 3

Interest compounded so n= 1

R= 3.4%

A= 1800(1+3.4/100)^3 = 1800 (1+0.034)^3 = 1800 (1.034)^3 = 1989.9131472

Interest in 3 yrs = 1989.9131472 - 1800 =

189.9131472

For B is below

Hopefully this help you :D
