For a circle of radius 4 with center (-4, 3). in general form

Answers

Answer 1

Answer: I'm going to assume that you're asking for the equation of that circle.
It's

(x + 4)² + (y - 3)² = 16

Answer 2

Answer: Reduced Equation:

$(x-x_o)^2+(y-y_o)=r^2\n \n (x+4)^2+(y-3)^2=16\n \n x^2+8x+16+y^2-6y+9-16=0\n \n \boxed{x^2+y^2+8x-6y+9=0}$

Mike works h hours in a week. To find his weekly pay he multiplies his hours by his pay of $30 per hour and adds $5 for his sales bonus. He's decided that he wanted to take one-fifth of his weekly pay and place it in his savings. Which simplified expression represents the amount that will go into his savings each week?

Answers

6h + 1

Step-by-step explanation:

number of hours: h

pay per hour: 30

. Maria spent 1\9of the money her grandparents gave her on an adventure book. She also spent 1/3 of the money on a bag of candy. What fraction of the payment has Maria spent?

Answers

Answer:

$(4)/(9)$

Step-by-step explanation:

The fraction of the money that Maria spent on an adventure book = $(1)/(9)$

The fraction of the money that Maria spent on a bag of candy = $(1)/(3)$

Now we have to find the total fraction of the money that Maria spent.

For that we have to add those 2 fractions together.

Let us solve now.

$( 1)/(9) +(1)/(3)$

$( 1)/(9) +(1*3)/(3*3)$

$(1)/(9) +(3)/(9)$

$(4)/(9)$

There fore, the fraction of the payment has Maria spent is $(4)/(9)$

Hope this helps you :-)

If you add 1/9 and 1/3, it becomes 1/9+3/9, which equals 4/9. thus, 4/9 of the money has been spent. hope it helps!!
