What property would you use first to solve 1/2x-6=10

NISA [10]

I don't know what you mean by property. Do you mean like, commutative, distributive, etc?

but, if this is what you mean:

to solve this:

The operation here is subtraction. Do the inverse. So, add 6 to both sides of the equation

10 + 6 = 16

1/2x - 6 + 6 = 1/2x. (the 6 cancels out)

1/2x = 16

Now, I'm going to assume 1/2 is supposed to be a fraction (not division). So, 1/2 is right next to x which represents multiplication, so do the opposite which is division.

16 divided by 1/2 = 32

1/2x divided by 1/2 = x

x = 32.

Triangle GHI, with vertices G(-8,-8), H(-6,-7), and I(-9,-2),

Anna35 [415]

Answer:

area = 6.5 square units

Step-by-step explanation:

Use the <em>area of a triangle in coordinate geometry</em> formula:

$\triangle GHI =\frac{1}{2} |x_1(y_2- y_3) + x_2(y_3 -y_1) + x_3(y_1 -y_2)|$

where $(x_1,y_1)=(-8,-8) \ \ \ \ (x_2,y_2)=(-6,-7) \ \ \ \ (x_3,y_3)=(-9,-2)$

$\triangle GHI =\frac{1}{2} |x_1(y_2- y_3) + x_2(y_3 -y_1) + x_3(y_1 -y_2)|$

$\implies \triangle GHI =\frac{1}{2} |-8(-7+2) -6(-2 +8) -9(-8 +7)|$

$\implies \triangle GHI =\frac{1}{2} |40 -36 +9|$

$\implies \triangle GHI =6.5$

Find the distance between (-5, -8) and (-1, -16). Group of answer choices 8.9 units 9.8 units 10.3 units 11 units

Marta_Voda [28]

The distance between (-5 , -8) and (-1 , -16) is 8.9 units ⇒ 1st answer

Step-by-step explanation:

The distance between points $(x_{1},y_{1})$ and $(x_{2},y_{2})$

is $d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

To find the distance between two points

Chose one of the two point to be $(x_{1},y_{1})$
Use the other point to be $(x_{2},y_{2})$
Substitute them in the rule of the distance

∵ The first point is (-5 , -8)

∵ the second point is (-1 , -16)

∴ $x_{1}$ = -5 and $x_{2}$ = -1

∴ $y_{1}$ = -8 and $y_{2}$ = -16

- Substitute these values in the rule of the distance

∵ $d=\sqrt{(-1--5)^{2}+(-16--8)^{2}}$

∴ $d=\sqrt{(-1+5)^{2}+(-16+8)^{2}}$

∴ $d=\sqrt{(4)^{2}+(-8)^{2}}$

∴ $d=\sqrt{16+64}$

∴ $d=\sqrt{80}$

∴ d = 8.9 units

The distance between (-5 , -8) and (-1 , -16) is 8.9 units
