Answer:
y = 20 + .5x
Step-by-step explanation:
Suppose that a cell phone monthly rate plan costs the user 5 cents per minute beyond a fixed monthly fee of $20. This implies that the relationship between monthly cost and monthly number of minutes is linear. Write an equation that relates total monthly cost to monthly minutes used.
Fixed monthly fee = $20
Fee per minute = $0.5
Number of minutes = x
Variable monthly cost = 0.5x
Let Total monthly cost = y
Total monthly cost = fixed monthly cost + variable monthly cost
y = 20 + .5x
Equation that relates total monthly cost to monthly minutes used is y = 20 + .5x
Your answer is
- Slope = -1.000/2.000 = -0.500
- x-intercept = 7/1 = 7.00000
- y-intercept = 7/2 = 3.50000
Step-by-step explanation:
Answer:
10.44 m
Step-by-step explanation:
Solve this as a triange. The base is 3m and the perpendicular is 10m. The angle between the base and wall is 90° so it will be a right angled triangle.
Solve this by Pythagoras theorm:
let length of ladder is c
base is b
And perpendicular is a
Acc to Pythagoras theorem:
C² = a² + b²
C² = 10² + 3²
C² = 100 + 9
C² = 109
√C² = √109
C = 10.44m
Answer:
p = 23 and p = -22
Step-by-step explanation:
| 2p -1 | =45
Absolute value equations have 2 solutions, one positive value and one negative
2p-1 = 45 and 2p-1 = -45
Add 1 to all sides
2p-1+1 = 45+1 and 2p-1+1 = -45+1
2p = 46 2p = -44
Divide by 2
2p/2 = 46/2 and 2p/2 = -44/2
p = 23 and p = -22
Answer:
A) -292.5
Step-by-step explanation:
-65 x 9 = -585
-585 ÷ 2 = -292.5
