Answer:
A: The sum of two rational numbers is always rational. I just took the test.
Step-by-step explanation:
Rational numbers are numbers that can be written as a fraction or ratio where irrational number cannot be written as a fraction or ratio.So the product or sum of two rational number is rational. Since your needed to find the false statement then the first one was the correct one.
Answer:

Step-by-step explanation:
We can write the following system of equations:
, with variables as defined in the question.
Multiply the first equation by
and add both equations to isolate and solve for
:
.
Answer:
The (-3x-9)=27 and (-5x-2)=10
Step-by-step explanation:
Sin^2x = 1 - cos^2 x
= 1 - 0.67^2
= 0.5501
sin x = sqrt 0.5501 = 0.7424 to nearest 10 thousandth
The equation of a straight line is given by:
y = mx + c
where m is the slope and c is the y-intercept.
From the given graph, the y-intercept is 1.
The slope of a straight line is given by:

Where

and

are two points on the line.
From the graph, (0, 1) and (14, 8) are two points on the line, thus:

Therefore, the equation representing the graph is
