(3,4) (9,7)
to find the slope
m = (y2-y1)/(x2-x1)
= (7-4)/(9-3)
3/6
1/2
The slope is 1/2
point slope form
y-y1 = m(x-x1)
y-4 = 1/2(x-3)
distribute
y-4 = 1/2x -3/2
add 4 to each side
y = 1/2 x -3/2 + 4
y = 1/2 x -3/2 + 8/2
y = 1/2 x + 5/2
this is in slope intercept form
You have to multiply whats outside the parenthesis with everything that is inside, so
Multiplication of same bases we sum the exponents
Alternative B.
Expression with parenthesis: = 2 ( l + w)
Expression without parenthesis = 2l + 2w
The property we used is known as "Distributive Property"
Let, width = w
Length = w + 70
Perimeter would be: P = 2(w+70+w)
p = 2(2w+70)
p = 4w + 140
Hope this helps!
Answer:
Two distinct real solutions.
Step-by-step explanation:
Given the equation in the form 
, you need to find the Discriminant with this formula:
For the equation 
you can identify that:
Then, substituting these values into the formula, you get that the Discriminant is:
Since 
, then has two distinct real solutions.
