Solve for d

d=5t+2

d=2+5t (divide both sides of the second one by two)

so they are both equal to d=5t+2

That means that the graph of the solutions to the system is a straight line - because every point on the line would be a solution to the system. It also means that the equation are equivalent. This means that every solution to the first equation is a solution to the second equation.

This question is poorly worded because they both go the same direction, but since parallel lines are defined as lines that never intersect, and these lines do intersect (they're the same line)...

Among the four, the false statement is "The graphs of the equations are parallel lines."

Answer:

The graphs of the equations are parallel lines.

Step-by-step explanation:

This is the false statement because all they did was DOUBLE the top equation and wrote the new equation below it. This would be considered dependency. Whenever we have infinitely many solutions, we have a dependent system of equations.

Answer:

Angles 7, 2, and 6

Step-by-step explanation:

Angle 7 is congruent by corresponding angles to angle 3.

Angle 2 is congruent by vertical angles to angle 3.

Angle 6 is congruent by vertical angles to angle 7, which is congruent to angle 3, so angle 3 and angle 6 must also be congruent.

Answer:

You would expect 75 cartons with at least 1 broken egg.

There are likely to be 222 DVD players that are defective.

Step-by-step explanation:

Both examples given in this question represent a ratio of broken or defective to a sample number of cartons or DVD players. In order to find how many would be broken or defective overall, you can set up equivalent ratios, or proportions.

Egg Cartons: $\frac{broken}{#cartons}=\frac{3}{20}=\frac{x}{500}$

'x' represents the number of cartons out of 500 that would be expected to have at least 1 broken egg. To solve for 'x' you can cross-multiply and divide, or you can find what factor you would multiply the denominator by to get 500 and then multiply the same factor by the numerator to find 'x'. In this case 500/20 = 25, so the factor is 25. 3 x 25 = 75, so you have 75 expected cartons with a broken egg.

DVD Players: $\frac{defective}{#players}=\frac{3}{50}=\frac{x}{3700}$

'x' represents the number of DVD players out of 3700 that would be expected to be defective. To solve for 'x' you can cross-multiply and divide, or you can find what factor you would multiply the denominator by to get 3700 and then multiply the same factor by the numerator to find 'x'. In this case 3700/50 = 74, so the factor is 74. 3 x 74 = 222, so you have 22 likely defective DVD players.
