Hello :
an equation is : (x+2)² +(y-7)² = 4
x² +4x+4 +y² -14y +49 = 4
x² +4x+y² -14y +49 = 0 ....( answer : 3)
Answer:
Step-by-step explanation:
As the equation is given in the question as follows.
2.5(6x-4)=10+4(1.5+0.5x)
open the bracket
2.5 × 6x - 2.5 × 4 = 10 + 4 × 1.5 + 4 ×0.5x
15x - 10 = 10 + 6 + 2x
15x - 2x = 16 + 10
13x = 26
x = 2
Its easy all you do is add the time given or subtract it
No the inequality symbol only changed when you divide a negative number from both sides.
Add all of the numbers together , and then divide by how many numbers your adding up. in this case you would divide by 8.
