Answer:

Step-by-step explanation:

2. 2(3x+4)=10

6x+8=10

6x+8-8=10-8

6x=2

x= 1/3

3. 2x + 7 = 5x + 16

7 + 2x = 5x + 16

7 + 2x = 16 + 5x

7 + 2x + -5x = 16 + 5x + -5x

7 + -3x = 16 + 5x + -5x

7 + -3x = 16 + 0

7 + -3x = 16

7 + -7 + -3x = 16 + -7

0 + -3x = 16 + -7

-3x = 16 + -7

-3x = 9

x = -3

4. x/3-8=-2

x/3=6

x=18

5. 3x-6=-12

3x-6+6=-12+6

3x=-6

x=-2

sorry but i cannot solve 1 or 6 because i am quite stupid

The coordinates of the vertexes of a triangle are A(3,3) B(6,6) C(9,3). What will be the new coordinates after a dilation

yuradex [85]

Answer:

Step-by-step explanation:

Dilation by 3 from origin causes each point to be multiplied by 3.

(3,3) * 3 = (9, 9)

(6, 6) * 3 = (18, 18)

(9, 3) * 3 = (27, 9)

which is A

Find the area of triangle ABC with vertices A(2,1), B (12,2), C (12,8). Hence, or otherwise find the perpendicular distance from

Lapatulllka [165]

<h2>The area of a triangle is =54 square units</h2><h2>The perpendicular distance from B to AC is = $\frac{108}{\sqrt{149} } units$ </h2>

Step-by-step explanation:

Given a triangle ABC with vertices A(2,1),B(12,2) and C(12,8)

$x_1=2,y_1=1,x_2=12,y_2=2,x_3=12 and y_3=8$

The area of a triangle is= $\frac{1}{2} [x_1(y_2-y_3) +x_2 (y_3- y_1)+x_3(y_1-y_2)]$

= $|\frac{1}{2} [2(2-8+12(8-1)+12(1-2)]|$

= $|-54|$ = 54 square units

The length of AC = $\sqrt{(x_1-x_3)^{2} +(y_1-y_3)^2}$

= $\sqrt{(2-12)^{2} +(1-8)^2}$

= $\sqrt{149}$ units

Let the perpendicular distance from B to AC be = x

According To Problem

$\frac{1}{2} \times x \times \sqrt{149} = 54$

⇔ $x =\frac{108}{\sqrt{149} }$ units

Therefore the perpendicular distance from B to AC is = $\frac{108}{\sqrt{149} } units$
