The answer is the first option: Even.
The explanation for this exercise is shown below:
1. By definition, if the fucntion is even.
2. When the graph is symmetric with respect to the y-axis, it is an even function.
3. As you you can see in the graph attached in the problem, the graph is symmetric about the y-axis. Therefore, you can conclude it is an even function.
Answer:
expanded form: 5 * 5 * 5
value: 125
Step-by-step explanation:
Answer:
they are equivalent
Step-by-step explanation:
simplifying 12r + p -4r + 6p you get 8r + 7p
so yes they are equal
Answer:
See explanation
Step-by-step explanation:
Let x be the number of spade shovels, y -the number of flat shovels and z - the number of square showels sold that day.
The store keeps an inventory of 80 shovels, then
x+y+z=80
The store always buy twice as many spade shovels as square, so
x=2z
The total cost of all shovels is
16x+9.60y+12.80z=1,072
a) The system of three equations is
b) In matrix form this is
c) The determinant is
d) Find three determinants:
So,
e) If the store doubled all prices and inventory, then the new matrix is
