Answer:
y
= −
5/
4
x − 7
Step-by-step explanation:
Answer:
<h3>
x = 2</h3><h3 />
Step-by-step explanation:
use Pythagorean theorem:
a² + b² = c²
where a = x
b = 8/2 = 4
c = √20
plugin values into the formula:
x² + 4² = (√20)²
x² + 16 = 20
x² = 20 - 16
x = √4
x = 2
Answer:
48/37
Step-by-step explanation:
Use the formula (y1 - y2)/(x1 - x2).
Plug in your x and y values to get (92 + 4)/(81 - 7).
Simplify down to get 96/74 and simplify again to get 48/37.
( - 45, 0)
to find the x-intercept let y = 0 in the equation
x = 0 → 
x = - 15
multiply both sides by 3
x = 3 × - 15 = - 45
x-intercept = ( - 45, 0)
For plan A it will only take five minutes to amount to $20.50
Plan B will need 30 min to cost the same as plan A $20.50
