Answer:

y = 3x - 17

========================

<h3>Given line</h3>

y = 3x - 8

Parallel lines have equal slopes, so its equation is in the form of:

y = 3x + b

Since it passes through the points (4 , - 5), find the value of the y-intercept b by substituting x- and y- coordinates into this equation:

- 5 = 3*4 + b
- 5 = 12 + b
b = -5 - 12
b = - 17

The equation of the parallel line is:

y = 3x - 17

The tangent ratio is the ratio of opposite (500 ft) to adjacent (x).
tan(29°) = (500 ft)/x
x = (500 ft)/tan(29°)
x ≈ 902 ft

The perimeter of an equilateral triangle is 6n - 15. Write an expression to represent the length of each side.

Kamila [148]

Answer:

Each side is 2n - 5.

Step-by-step explanation:

The perimeter of an equilateral triangle is given by:

$P=3s$

Where s is the length of each side.

The total perimeter is given by:

$6n-15$

So, by substitution:

$6n-15=3s$

Then the length of each side is:

$s=\displaystyle \frac{1}{3}(6n-15)=2n-5$

Each side measure 2n - 5.

Determine if a triangle can be formed with 40 given sides. Show your calculations to support your yes or no answer.

Tanzania [10]

If sum of 2 shorter sides > longest side , then a triangle can be formed.
9.) 6 + 8 = 14 > 10; yes
10.) 7 + 8 = 15 > 10; yes
11.) 75 + 25 = 100 = 100; no
12.) 1 + 1 = 2 = 2; no
