Answer:
The first graph will be correct.
Step-by-step explanation:
The given inequality is y + 5 < x .......... (1)
Now, straight-line y + 5 = x will be the reference line of the solution of the given inequality (1).
Now, y + 5 = x
⇒ x - y = 5
⇒ ......... (2)
This equation is in intercept form and the straight line will pass through the points (5,0) and (0,-5)
Now, point (5,0) does not satisfy inequality (1) and hence, the line (2) is not included in the solution of the inequality (1).
Now, (0,0) point is above the line (2), but (0,0) point also does not satisfy inequality (1) as .
Therefore, the solution of the inequality is below the line (2) but not including the line.
Hence, the first graph will be correct. (Answer)
3X+2Y=6
3X+1Y=5
Those are linear equations.
we can solve by elimination method.
3X+2Y=6
3X+1Y=5
⇒Y=1
∴X=4/3
Answer:
The cost of each battery is .59
Step-by-step explanation:
Divide 4.72 by 8 to get the answer
Let the number of hours = x
Mine A is offering his services for an initial $90 in addition to $15 per hour.
So, Charges of A = 90 + 15x
Mine B is offering her services for an initial $30 in addition to $35 per hour.
so, Charges of B = 30 + 35x
The two mines charge the same amount of money when:
Charges of A = Charges of B
So,
solve for x
combine like terms
so, the two mines will charge the same amount of money when the number of hours = 3
