Answer:
Step-by-step explanation:
Let the equal number of hours be represented by variable H;
The two equations will be as follows;
Jack; 40 +30H
Mark; 50 +25H
Next, equate them;
40 + 30H = 50 + 25H
30H - 25H = 50 - 40
5H = 10
H =10/5
H = 2hrs
Therefore, they charge the same amount at 2 hrs.
B.) The amount charged;
Replace the variable H in any of the two equations above with 2 to solve for the amount.
Equation 40+30H = 40 + (30*2)
=40 + 60
= $100
1.1 Pull out like factors :
-8x - 2 = -2 • (4x + 1)
2.1 Divide both sides by -2
Remember to flip the inequality sign:
2.2 Divide both sides by 4
x+(1/4) ≥ 0
Solve Basic Inequality :
2.3 Subtract 1/4 from both sides
x ≥ -1/4
Find the point in which the x = 1, and the y point meets.
When x = 1, y = 2
2 is your answer for y
hope this helps
