The triangle with sides 5, 12, 13 is a right triangle because

a^2+b^2 = c^2

5^2+12^2 = 13^2

25+144 = 169

169 = 169

I'm using the pythagorean theorem converse.

(SHOW WORK) Write the slope-intercept form of the equation:

stiks02 [169]

Answer:

$\displaystyle y = -4x - 5$

Step-by-step explanation:

We want to find the slope-intercept form of the equation that passes through the point (-2, 3) and is perpendicular to the line:

$\displaystyle y = \frac{1}{4} x - 4$

Note that this line has a slope of 1/4.

Recall that the slopes of perpendicular lines are negative reciprocals of each other.

Since the slope of our old line is 1/4, the slope of its perpendicular line must be -4.

We are also given that it passes through the point (-2, 3). So, we can consider using point-slope form:

$\displaystyle y - y_1 = m(x - x_1)$

Let (-2, 3) be (x₁, y₁) and substitute -4 for the slope m. Hence:

$\displaystyle y - (3)= -4 (x - (-2))$

Convert into slope-intercept form. Simplify:

$\displaystyle \begin{aligned} y -3 &= -4 (x + 2) \\ y - 3 &= -4x - 8 \\ y &= -4x -5\end{aligned}$

In conclusion, the perpendicular line that passes through the point (-2, 3) is given by:

$\displaystyle y = -4x - 5$

the product of two consecutive integers is 5 more than three times the larger integer. Find the larger integer. please help!

Blababa [14]

Answer:

x = 5 or -1

Step-by-step explanation:

let larger integer be: x

the smaller integer is: x-1

(x)(x-1)=5+3(x)

x^2-x-5-3x=0

x^2-4x-5=0

x = 5 or -1
