Use the Pythagorean Theorem:
a² + b² = c²
4² + b² = 8.5²
16 + b² = 72.25
b² = 56.25
b = 7.5
The ladder reaches a height of 7.5 ft on the wall
<h2>Answer</h2>
Slope =
x-intercept =
y-intercept = -4
<h2>Explanation </h2>
Remember that the equation of a line in general form is:
where
Notice that to express our equation, , in general form, we just need to subtract 12 from both sides of the equation:
Now can infer that , , and . So let's replace the values in our formulas:
To find the x-intercept, we just need to replace with zero in our general or original equation and solve for :
30 days, hath September. April June, and November. All the rest have 31, except for February, which has 28. And 29 on a leap year.
