Rearrange Line 1 and Line 3’s equations in the form of y = mx + c for easier comparison.
Lines 1 and 2 are parallel, because they have the same gradient.
Lines 1 and 3, and 2 and 3 are neither, because their gradients do not multiply to form -1.
(Gradients of perpendicular lines multiply to form -1.) c

please answer this question urgent
Hours of work: 40....20....10....6
Payment per hours: 400....200...100...60
Or
Hours of work:2....4....6
Payment per hours:20....40....60. Luz earns 10 dollars per hour.
6 persons * $8= $48
4 popcorns * $6.25= $25
6 persons * $2.75= $16.5 (drinks)
$48+$25+$16.5= $89.50 total
Answer:
x (40-10) -12000≥980
The factory must sell 433 backpacks to meet its weekly goal.
Hi, to answer this question we have to write an inequality.
So, since the backpacks (x) are sold by $40 and the cost of making one is $10, the revenue per bag is equal to 40x and the cost is 10x.
12,000 of operating expenses are also expenses.
So, for the profit:
Profit = revenue- cost
P = 40x-10x-12,000
P = x (40-10)-12000
The factory goal is to make a profit of at least $980 each week, so, the profit must be greater or equal than 980.
x (40-10) -12000≥980
Solving for x
30x-12000≥980
30x≥980+12000
30x ≥12980
x≥12980/30
x≥432.6
x≥433 (rounded, because if the sell 432 they will not meet the goal)
The factory must sell 433 backpacks to meet its weekly goal.
