Hello!
Use the slope formula to determine the slope between the points:
m = (y2 - y1) / (x2 - x1)
Plug in the values:
m = (7 - 2) / (10 - 5)
m = 5 / 5
m = 1
Answer:
54 cheese pizzas
Step-by-step explanation:
We know that there are 120 pizzas in the freezer, and 45% of them are cheese pizzas.
We want to find out how many cheese pizzas are in the freezer, so we should multiply 45% and 120.
45% * 120
Convert 45 % to a decimal. Divide 45 by 100 or move the decimal place 2 spots to the left.
45/100= 0.45 or 45.0 --> 4.5 ---> 0.45
0.45 * 120
Multiply 0.45 and 120
54
54 cheese pizzas are in the freezer.

Answer:
[2 5 0]
[-7 -11/2 12]
Step-by-step explanation:
We want to perform elementary row operation represented by R2 - ½R1 on matrix A in the figure attached.
Now, matrix A is given as;
[2 5 0]
[-6 -3 12]
Now, R1 is row 1 = [2 5 0]
R2 is row 2 = [-6 -3 12]
Thus, R2 - ½R1 = [-6 -3 12] - ½[2 5 0]
This gives;
[-6 -3 12] - [1 5/2 0] = [-7 -11/2 12]
Now,[-7 -11/2 12] will be the new row 2 since it's just an elementary row operation we did on the Matrix A.
Thus, the new matrix is now;
[2 5 0]
[-7 -11/2 12]
