Write an equation of the line that passes through (2,−5) and is parallel to the line 2y=3x+10

LenaWriter [7]

Step-by-step explanation:

Divide two on both sides to get rid of it and the make the equation in the form y = mx + c

$\frac{2}{2} y = \frac{3}{2} x + \frac{10}{2}$

y = 3/2x + 5

since both lines are parallel they must have the same gradient which is 3/2

y = 3/2x + c

All you have to do now is to replace x and y with (2, -5) to find c

x = 2

y = -5

-5 = 3/2 × 2 + c

-5 = 3 + c

c = -5-3

c = -8

$y = \frac{3}{2} x - 8$

Brilliant_brown [7]

Answer:

Percent increase = 60%

Percent increase with baggage = 83%

Step-by-step explanation:

Given that:

Old price of the ticket = $210

New price of the ticket = $335

Increase amount =335-210 = $125

Percent increase = $\frac{Inrease\ amount}{Old\ price}*100$

Percent increase = $\frac{125}{210}*100 = 0.595*100$

Percent increase = 59.52% = 60%

Additional charges = $125+$50 = $175

Percent increase = $\frac{175}{210}*100$

Percent increase = 83%

Hence,

Percent increase = 60%

Percent increase with baggage = 83%
