7 0

Answer:

y=2

Step-by-step explanation:

-(3y+2) -(-2y-4)=0

Distribute the minus signs

-3y -2 +2y +4 = 0

Combine like terms

-y +2 = 0

Add y to each side

-y+y +2 = 0+y

2=y

Check

-(3*2+2) -( -2*2-4) =0

-(6+2) -(-4-4)=0

-8 - (-8) =0

-8+8 =0

0=0

The standard form of a circle is

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

(x-0)^2+ (y--2)^2 = 7^2

(x)^2+ (y+2)^2 = 49

this is just a example

Use properties of rational number to simplify the expression.
Naddika [18.5K]

Answer:

A.)129/7

Step-by-step explanation:

25/4 + 24/7 + 35/4

I will add the two with common denominator together first

25/4 + 35/4     +24/7

60/4   +24/7

15  + 24/7

We need to get a common denominator of 7

15 *7/7  + 24/7

105/7  + 24/7

129/7
