First, distribute
3(x-7)=3x-21
3x-21-x=2x-21
3x-1x-21=2x-21
add like terms
2x-21=2x-21
minus 2x oth sides
-21=-21
true
we see that the x's wil cancel
therfor x=all real numbers
Solution :
The probabilities are assigned using the empirical probability (experimental).
= 0.194
= 0.227
= 1 - 0.194 - 0.227
= 0.579
≈ 0.58
∴ event of B or event of C
So the probability of is 0.81
The expressions for the width, W, and area, A, of the rectangle in terms of L are:
- W = - L
- A =
The expression for the perimeter of a rectangle is given as:
P = 2(L + W)
where L is its length and W its width
a. Given that the perimeter of the rectangle is 13 feet, then;
13 = 2(L + W)
divide through by 2
= L + W
So that;
W = - L
The required formula for the width as a function of L is: W = - L
b. Area of a rectangle can be expressed as;
A = L * W
substitute the expression for width in that of area to have
A = L * ( - L)
= L -
A =
The expression for the area A is: A =

Answer:
D. Undefined
Step-by-step explanation:
The slope is the ratio of rise to run. When the line is vertical, the run is zero, so calculating the slope involves division by zero. That makes the slope be <em>undefined</em>.
