We know that
A relationship between two variables, x, and y,<span> is proportional if it can be expressed in the form y/x=k or y=kx</span>
in this problem
k=2
then
y=2x
therefore
the answer is the option
y=2x
Answer:
see below
Step-by-step explanation:
For the HL theorem to be applicable, the hypotenuses must be the same length:
x+3 = y-1
and the marked legs must be the same length:
y-3 = 2x-1
__
Recognizing y-3 = (y-1) -2, we can substitute into the second equation using the first equation:
(y -1) -2 = 2x -1
(x +3) -2 = 2x -1 . . . substitute for y-1
2 = x . . . . . . . . . . add 1-x to both sides
Then the first equation tells us ...
x+4 = y = 2+4 = 6
The values of x and y are ...
x = 2, y = 6
From the given, there are 5 toppings available. If the pizza is to contain only two toppings, that is one of the five toppings and one of either tomato and cheese then, there will be 10 ways to prepare the pizza. Lastly, if we include the pizza with no toppings then, we have 11 types of pizza.
A matrix 7 * 5 means a matrix of 7 rows and 5 columns.
The matrix can only have 5 pivot columns for the system to be linearly independent.
Remember that in the system of equations:
Ax = b
A is the coefficient matrix of the incognita vector x and b is the solution vector.
The extended matrix is
(A l b)
If the matrix has more than 5 pivot columns, then the system is linearly dependent.
It's 27. When dividing fractions, you multiply the first number by the reciprocal of the second number. The reciprocal of 1/3 is 3/1. 9x3/1=27
