Answer:

6.5a-26

Step-by-step explanation:

You have to use the distributive property and multiply each term inside the parentheses by 6.5. By doing this you turn 6.5(a-4) into (6.5)(a)-(6.5)(4). You can then simplify this into 6.5a - 26

Answer:

6.5a-26

Step-by-step explanation:

We are given the expression:

6.5(a-4)

If we want to simplify this expression, then we must use the distributive property.

To distribute, multiply each term inside the parentheses by the number outside the parentheses.

(6.5*a) + (6.5*-4)

Multiply

6.5a+ (6.5*-4)

6.5a+ -26

A +- can be written as just -

6.5a-26

A circle passes through (3,-1),(-2, 4), and (6,8)

Vaselesa [24]

Answer:

D = -6, E = -8 , F = 0

Step-by-step explanation:

standard form = $x^{2} + y^{2} + Dx + Ey + F = 0$

now, when circle passes through (3,-1);

⇒ $3^{2} + (-1)^{2} + D(3) + E(-1) + F = 0$

⇒ $3D - E + F + 10 = 0$ ...............( equation 1)

when circle passes through (-2,4);

⇒ $(-2)^{2} + 4^{2} + D(-2) + E(4)+ F = 0$

⇒ $-2D + 4E + F + 20 = 0$ ...............( equation 2)

when circle passes through (6,8);

⇒ $6^{2} + 8^{2} + D(6) + E(8) + F = 0$

⇒ $6D + 8E + F + 100= 0$ ................( equation 3)

by solving these 3 equations , we get;

D = -6, E = -8, F = 0

hence,

standard form = $x^{2} + y^{2} + Dx + Ey + F = 0$

= $x^{2} + y^{2} - 6x - 8y = 0$
