36
Step-by-step explanation:
Just multiply lol
Answer:
Step-by-step explanation:
As you can see the value of y increases uniformly with x, so this is a straight line. A straight line follows the formula of
When x=0, y=5, and therefore c=5
Use the formula of slope to calculate slope
Answer: x>2
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
2*x-(3-x)-(x+1)>0
Pull out like factors :
2x - 4 = 2 • (x - 2)
Divide both sides by 2
Add 2 to both sides
x > 2

Answer:
Refer below for detailed explanation.
Step-by-step explanation:
Standard equation:
1. ax^2+bx+c=0.
Quadratic formula:
2. x = -b+-sqrt(b^2-4ac)/2a. .
Now two equations to find the factored form through these formulas above.
Through this identifying a,b and c.
ax^2+bx+c=0.
x^2+4x-21=0
Here a=1, b=4, and c= -21
Now applying in the quadratic formula.
x=-4+-sqrt(4^2-4(1)(-21))/2(1)
Now solve it and it becomes
x=3 or x= -7.
Another example :
x^2+3x-4=0
Here a=1, b=3 and c=-4.
X=-3+-sqrt(3^2-4(1)(-4))/2(1)
Now solve it and
x= -4 and x=1
P.s have attached the picture of quadratic formula as well.
