Answer:
j=12
Step-by-step explanation:
Answer:
z=-4
Step-by-step explanation:
Simplify 10 + 2z + 2z to 10 + 4z
Add 10 to both sides
Simplify 10 + 4z + 10 to 4z + 20
Subtract 4z from both sides
Simplify -z - 4z − z− 4z to -5z − 5z.
Divide both sides by -5 − 5
Simplify 20 / 5 to 4
Answer:
(2, 3)
Step-by-step explanation:
y=y
6x-9=x+1
5x-9=1
5x=10
x=2
y=2+1
y=3
First you need to fine the slope
3,1
4,4
The slope with be m= 3
then put it in point slope from
y-1=3(x-3)
y-1=3x-9
y=3x-8
so the answer with be "A"
hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a =-2 and b = 2 (Center at the point A(-2;-2))
r= 10/2=5
the equation is : (x+2)² +(y+2)² =25</span></span>
