What is the slope of a line perpendicular to the line whose equation is 10x + 6у –84. Fully simplify your answer.​
mixer [17]

Answer:

The slope is 3/5.

Step-by-step explanation:

I am assuming you mean

10x + 6y = 84

6y = -10x + 84

y = -5/3 x + 14.

So the slope of this line is -5/3 and the slope of a line perpendicular to it is

-1 / -5/3 = 3/5.

Podstawa trójkąta KOS jest równa 6 cm, a wysokość opuszczona na tę podstawę jest jej połową. Oblicz pole trójkąta KOS i narysuj
grigory [225]

Answer:

<h3> the area of the triangle is 9cm²</h3>

Step-by-step explanation:

<u>Question in English</u>

The base of the KOS triangle is 6 cm, and the height lowered on this base is half of it. Calculate the area of ​​the KOS triangle and draw another triangle with the same field. Quick, please!

Given that:

The base is 6 cm

height is half  of the base, 6 / 2 = 3cm

Area of a triangle is

\frac{1}{2} \times base \times height

= \frac{1}{2} \times 6cm \times 3cm \\\\= 3cm \times 3cm\\\\= 9cm^2

<h3>Therefore, the area of the triangle is 9cm²</h3>
