8 0

Answer:

Dependent

Step-by-step explanation:

y=-3x+4 and 6x+2y=8

Lets solve the second equation for y and then substitute it in first equation

6x+2y=8

Subtract 6x on both sides

2y=-6x+8

Divide by 2 on both sides

y=-3x+4

Now we plug it in first equation for y

-3x+4=-3x+4

Add 3x on both sides

4=4

Both sides are same, they are equal. the system has infinite solutions.

They are said to be dependent

The quotient of a number and negative eight is five-eighths. Find the number.
max2010maxim [7]

Answer:

-64/5

Step-by-step explanation:

Basically, the word "quotient" means the answer to a division problem. Therefore, its a division problem, so you have to work backwards with multiplication. -8 times a number is 5/8, so the other number is going to be negative.

The number is -64/5

What equation describes the circle that is centered at (8, 3) and has a radius of 9
Sloan [31]

Answer:

<h3> (x-8)²+(y-3)² = 81</h3>

Step-by-step explanation:

The general equation of a circle is expressed as;

(x-a)²+(y-b)² = r² where;

(a, b) is the centre of the circle

r is the radius

Given the centre (8, 3) and the radius of 9, the equation of the circle will be;

(x-a)²+(y-b)² = r²

(x-8)²+(y-3)² = 9²

(x-8)²+(y-3)² = 81

hence the required equation is  (x-8)²+(y-3)² = 81

AB = 6x + 2 and<br> BC = 5x + 3<br> Find AC.
uranmaximum [27]

Answer:

AC = 3x + 3 (answers may vary)

Step-by-step explanation:

AB = 6x + 2

Answers may vary for this question,

Let's say that,

B = 4x + 1

So that means that,

A = 2x + 1

BC = 5x + 3

Since we chose

B = 4x + 1,

we must subtract B from BC to get C,

C = x + 2

Now we add A and C to get AC,

A = 2x + 1

C = x + 2

AC = 3x + 3
