A) three numbers sum to 15. The mode of the three numbers is 1. What must the three number be?
uysha [10]
The mode is a number that is repeated the most, so if there is 3 numbers, the "mode number" has to be repeated twice or three times. 

A)  since 1 is the mode, two of the numbers are 1, the last number is
15 -1 -1 = 13 <em> </em><em> the three numbers are 1, 1, and 13</em><em />.

B)  since 5 is the mode, two of the numbers are 5, the last number is
11 -5 -5 = 1 <em> </em><em> the three numbers are 5, 5, and 1</em><em />.

Range is when you subtract the smallest number to the biggest number, so 5-1=4  <em>The answer is 4</em>

Solve the system of equations algebraically. Verify your answer using the graph.
horrorfan [7]

For this case we have the following system of equations:

y = 4x-5\\y = -3

We solve by the matching method.

Matching we have:

-3 = 4x-5\\-3 + 5 = 4x\\2 = 4x\\\frac {2} {4} = x\\x = \frac {1} {2}

Thus, the solution of the system is given by:

(x, y): (\frac {1} {2}, - 3)

Answer:

(x, y): (\frac {1} {2}, - 3)
