A because I have done this before
Answer:
(P, Q) = (-75, 57)
Step-by-step explanation:
The equation will have infinitely many solutions when it is a tautology.
Subtract the right side from the equation:
Px +57 -(-75x +Q) = 0
x(P+75) +(57 -Q) = 0
This will be a tautology (0=0) when ...
P+75 = 0
P = -75
and
57-Q = 0
57 = Q
_____
These values in the original equation make it ...
-75x +57 = -75x +57 . . . . . a tautology, always true
Answer:
10.5
Step-by-step explanation:
Median is defined as the middle value- order the number from least to greatest ; if there is an even number of values, like in this case, order them from smallest to largest..... Add the two middle values and divide by 2..... The result is ur median
- 4,9<u>,10,11,</u>12,14
- 10+11=21
- 21÷2=10.5
Answer:
ratios equivalent to 1/3=2/6,3/9
Step-by-step explanation:
Double number line is a diagram used when. quantities have different units.
It shows each of the quantities on its own number line with corresponding pairs of values lined up.The values of each number line are not the same unless there is a 1:1 ratio between them.
some ratios equivalent to 1:3 are;
2:6,3:9,4:12,5:15,6:18,7:21,etc
