It is asking for the intercept.

y = x + 3 becomes y - x = 3

multiply it by two, so it becomes -2x + 2y = 6. Then add it to the other equation, and solve for y.

2x + 4y = 60

(2x + 4y) + (-2x + 2y) = 60 +6

6y = 66

y = 11

Plug in the known y into the the easiest equation.

11 = x +3

x = 8

Intercept: (8, 11)

Using the triangle below, find the ratio please need help answering for a quiz
Murrr4er [49]
<h3>sin22° = 5/4</h3><h3>tan22° = 3/√55</h3>

As we know that , sinA = opposite/hypotenuse & tanA = opposite/adjacent

So here we can find sin22° , because they already given the sides opposite & hypotenuse . And we can't find tann22° because they given the value of opposite but not given the value of adjacent side of the angle 22°

Now finding the adjacent side using

Pythagoras theorem :-

• Hypotenuse² = Base² + Height²

=> 40² = Base² + 15²

=> 1600 - 225 = Base²

=> Base² = 1375

=> Base = √1375

=> Base = 5√55

Now ,

  • tan22° = Opposite/Adjacent = 15/5√55 = 3/√55
  • sin22° = Opposite/hypotenuse = 15/40 = 5/4

Yanka [14]

Answer:A

Step-by-step explanation:

If the auto insurance covers theft up to $15,000 and his car value is less than it ($8,000), he is going to pay only $250 deductible. It means that it covers values until $15,000.
