Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Let y represent the cell phone bill for x minutes. Using points (230, 17.45) and (370, 19.55):
For 150 minutes:
y = 0.015(150) + 14 = 16.25
For $21.50:
21.50 = 0.015x + 14
x = 500
It would take 500 minutes for the cost to be $21.50.

سأعطي فقط مثالاً مقدمًا أدناه آمل أن يساعد
Step-by-step explanation:
الارتفاع = 24 سم
نصف القطر = 14 ÷ 2 = 7 سم
ارتفاع مائل = L =؟
L2 = R2 + H2
م 2 = 72 +242
م 2 = 49 + 576
م 2 = 625
L = 25
الحجم = 1 ÷ 3 × 22 ÷ 7 × 7 × 24
الحجم = 1232 سم
مساحة السطح المنحني = 22 × 7 × 7 × 25
مساحة السطح المنحني = 550
إجمالي مساحة السطح = 22 × 7 × 7 × 25 + 7
مساحة السطح الكلية = 704 سم

Answer:
Price per pound for cashews = $7
Price per pound for peanuts = $4
Step-by-step explanation:
Let,
x be the price per pound of cashews
y be the price per pound of peanuts
According to given statement;
4x+2y=36 Eqn 1
7x+6y=73 Eqn 2
Multiplying Eqn 1 by 3
3(4x+2y=36)
12x+6y=108 Eqn 3
Subtracting Eqn 2 from Eqn 3
(12x+6y)-(7x+6y)=108-73
12x+6y-7x-6y=35
5x=35
Dividing both sides by 5
Putting x=7 in Eqn 1
4(7)+2y=36
28+2y=36
2y=36-28
2y=8
Dividing both sides by 2
y=4
Hence,
Price per pound for cashews = $7
Price per pound for peanuts = $4
