Answer:

(x+3)^2 +(y-5)^2 = 36

Step-by-step explanation:

We can write the equation of a circle as

(x-h)^2 +(y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x- -3)^2 +(y-5)^2 = 6^2

(x+3)^2 +(y-5)^2 = 36

2/3 divided by 11/15

NNADVOKAT [17]

You need to implement the process of "flip-flop" and multiply which is where you flip the second fraction and multiply.

$\frac{2}{3}$ ÷ $\frac{11}{15}$ ⇒ $\frac{2}{3}$ × $\frac{15}{11}$

Now you multiply across. 2×15=30 and 3×11=33

So now it is $\frac{30}{33}$

-----------------------------------------------------------
To reduce to the lowest terms, find the GCF common factor

The GCF is 3

Divide both the numerator and denominator by 3

$\frac{30}{33}$ ÷ $\frac{3}{3}$ = $\frac{10}{11}$

Answer: $\frac{10}{11}$

5. Solve the problem by writing an inequality. A club decides to sell T-shirts for $12 as a fund-raiser. It costs $20 plus $8 pe

kykrilka [37]

T=the amount of shirts
12t-20-8t=100
12t-8t=120
4t=120
t=30
So they must sell at least 30 shirts to make $100.
