Is it possible t form a triangle with side lengths of 11.5 yd, 15.5yd and 9 yd? Proof

1 answer:

4 0

Given a triangle if side a, b and c where c is the longest side, then:
a+b≥c
From the dimensions given, we can assign our values as follows:
a=11.5, b=9, c=15.5
thus plugging in the inequality:
11.5+9≥15.5
20.5≥15.5
this implies that the dimensions form a triangle.

So, x=7/3, -1.
5=3x-2
x=7/3
Here change 5 to -5.
5= 3x-2
x=-1

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

Leto [7]

Answer:

Use the given slope and point to substitute into the point-slope formula y−y1=m(x−x1).

Slope-intercept form:

y=3x²+4x−25

Point-slope form:

y+5=(3x+10)⋅(x−2)

Divide (x^3-20x+16)/(x-4)

Lorico [155]

$\frac{( x^{3}-20x+16) }{(x-4)}$

Use the rational root theorem:
$a_{o}$ =16, $a_{n}$ =1

The dividers of $a_{o}$ : 1,2,4,8,16
The dividers of $a_{n}$ : 1

Therefore, check the following rational numbers: +- $\frac{1,2,4,8,16}{1}$

$\frac{4}{1}$ is a root of the expression, so factor out x-4

Compute $\frac{ x^{3}-20x+16 }{x-4}$ to get the rest of the equation.

$\frac{(x-4)( x^{2} +4x-4)}{x-4}$

Cancel the common factor:
$x^{2}+4x-4$ is the final answer
