Answer:
D
Step-by-step explanation:
The range of a function are the possible y-values (output values).
Options A and B are wrong, because the x-values are the input values.
The range is between -5 and -1 as shown in the graph (y-axis). The circle on the points are shaded so ‘≤’ is correct. Option C is wrong.
The range is greater than or equal to -5 and less than or equal to -1.
Answer:
x = -5, y = -6, z = -3
Step-by-step explanation:
Given the system of three equations:

Write the augmented matrix for the system of equations

Find the reduced row-echelon form of the augmented matrix for the system of equations:

Thus, the system of three equations is

From the last equation:

Substitute it into the second equation:

Substitute y = -6 and z = -3 into the first equation:

Answer:
if I am right it is 12,600 words
Step-by-step explanation: 90 divided by 3 which is 30 420x30=12,600
Divide the price by the quantity:
Bananas = 5.40 / 6 = 0.90 each
Oranges = 2.56/8 = 0.32 each
Apples = 4.68 / 12 = 0.39 each
Mangos = 3.16 / 4 = 0.79 each
Oranges have the lowest price each so are the best buy.
X + x + 36 = 90
2x = 54
x = 27 Answer
