Answer:
Option C is correct
Step-by-step explanation:
In this question, we are asked to select which of the options have the same value as 7/3
We examine the options one urge other.
Option A
9/49; This is wrong as it cannot be divided further to yield while multiples
Option B
18/42; Dividing through by 6 will yield 3/7 which is not same as 7/3; This makes this option wrong too
Option C
42/18; dividing through by 6 will yield 7/3 which makes this option correct
Option D
49/9; This is a dead end as it cannot be divided further to give whole number multiples
Answer:
b

Answer:
Dalia had an average airspeed of 42 miles per hour
The average wind speed was 12 miles per hour
A. True
In the equation <span>2x+y=4, subtracting 2x to both sides, we get y=-2x+4
B. True
The graph of equation </span>y=-2x+4 is composed of all the solutions (x, y) of the equation.
<span>
C. Wrong
The graph of the equation is only one line, whereas the set of all points on the coordinate plane means the whole plane.
D. True
Substituting (x, y) with (1, 2) in </span>y=-2x+4, we have 2=-2*1+4, which is true.
Thus the point (1, 2) is a solution of the equation, so it is a point on the graph of the equation.
E. False
Substituting x with 0 in -2x+4, the expression becomes 4, which is not equal to 2. So this point is not a solution, therefore it is not on the graph.
Answer: A, B, and D are true
