Answer:
y=2x-2
Step-by-step explanation:
find the slope (m)
m=y2-y1/x2-x1
m=4-(-2)/3-0
m=4+2/3-0
m=6/3
m=2
y-y1=m(x-x1)
y-(-2)=2(x-0)
y+2=2x
y=2x-2
Answer:
72
Step-by-step explanation:
8 times 9 equals 72
The side is 3 so it would be 3 times 5, your answer is 15
The roots are 1 +√7 and 1 -√7.
<h3>What is Quadratic equation?</h3>
A quadratic equation in the variable x is an equation of the form ax² + bx + c= 0, where a, b, c are real numbers, a≠0
Given equation:
y= x²+2x-6
First,
Half the coefficient of x and add and subtract the square of (b/2)
y= x²+2x-6+(1)²-(1)²
y= x²+2x+(1)² -6 -(1)²
y= (x+1)² -7
Now, equate y=0
(x+1)² -7 =0
(x+1)² = 7
x+1= ±√7
x=1 ±√7
Hence, the roots are 1 +√7 and 1 -√7.
