Find the area of the triangle defined by the coordinates (7, 1), (0, 10), and (9, 4). (To the nearest tenth)
slega [8]

Answer:

  C)  19.5 square units

Step-by-step explanation:

The area from coordinates can be computed as ...

  A = (1/2)|x1(y2 -y3) +x2(y3 -y1) +x3(y1 -y2)|

  = (1/2)|7(10 -4) +0(4 -1) +9(1-10)| = (1/2)|7·6 +9·(-9)|

  = (1/2)|-39| = 39/2 = 19.5

The area of the triangle is 19.5 square units.

3 (3n-4)=3 (n+4) help help​
tatuchka [14]
(3n-4)=3(n+4)
3n-4=3n+12
no solution

There wouldn’t be a solution to this equation because the n cancels out when you subtract 3n-3n.

3/4(8x-4)=7x+2 This is a linear equation please help!
aleksandrvk [35]

Simplify the left hand side by multiplying the terms in the parenthesis by 3/4, i.e. divide them by 4 and multiply them by 3:

\dfrac{3}{4}(8x-4)=7x+2 \iff 3(2x-1)=7x+2 \iff 6x-3 = 7x+2

Subtract 6x from both sides:

-3=x+2

Subtract 2 to both sides:

x=-5
