Answer:
y = 8
Step-by-step explanation:
Line1 with points (4, 1) and (0, 0):
slope = (y₂ - y₁) / (x₂ - x₁)
= (0 - 1) / (0 - 4)
= 1/4
Perpendicular line is opposite inverse so original slope 1/4 becomes -4/1 or simply -4.
Line2 with points (1, 0) and (-1, y):
slope = (y₂ - y₁) / (x₂ - x₁)
= (y - 0) / (-1 - 1)
= y / -2
y must equal to 8 for the slope to be -4 as stated above.
Answer:
$230n-$2100
Step-by-step explanation:
Profit=revenue-cost
Cost=$2100+$130×n
Revenue=$360×n
Profit=$360n-($2100+$130n
=$360n-$2100-$130n
=$230n-$2100
Answer: Linear function; the rate of change is consistant
Answer:
Step-by-step explanation:
P= 2(L) + 2(w)
1504= 2(525) + 2(w)
1540= 1050 + 2(w)
1540 - 1050= 2(w)
490 = 2(w)
490/2 = w
245 = w
w is y
L is 525
Answer:
67
Step-by-step explanation:
When two angles are complimentary, it means that, together, they make a 90 degree angle.
/_A + /_B must equal 90°
