Answer:

see explanation

Step-by-step explanation:

Divide the coordinates of the dilation by the original coordinates

(8)

\frac{6}{9} = \frac{8}{12} = \frac{2}{3}

(9)

\frac{12}{10} = \frac{-8}{-15} = \frac{6}{5}

(10)

\frac{-9}{-1} = 9

If 3x-8=-2 fins the value of x-6
adell [148]

Steps to solve:

3x - 8 = -2; x - 6

~Substitute

3(x - 6) = -2

~Distribute left side

3x - 18 = -2

~Add 18 to both sides

3x = 16

~Divide 3 to both sides

x = 16/3

Best of Luck!

96 ÷ 42 + (25 x 2) - 15 - 3=? I need help with my math
ANTONII [103]
Pemdas
so do parenthaseese first
work inside then out
(25 times 2)
(50)
now we have
96/42+(50)-15-3=?

start from the begining again of the equation (left) now we do division
96/42=16/7

now we have 16/7+(50)-15-3
start over and do addition
16/7+50=2 and 2/7+50=2+2/7+50=52 and 2/7
subtract
52 and 2/7-15=52+2/7-15=37 +2/7=37 and 2/7
then subtract 3
37 and 2/7-3=37+2/7-3=34+2/7=34 and 2/7

answer is 34 and 2/7

One angle of a triangle is 30° more than the smallest angle. The largest angle is the sum of the other angles. Find the measures
vladimir1956 [14]

Answer: \boxed{30^{\circ}, 60^{\circ}, 90^{\circ}}

Step-by-step explanation:

Let the smallest angle be x.

Then, the middle angle is x+30.

The largest angle is 2x+30.

Angles in a triangle add to 180 degrees, so:

x+x+30+2x+30=180\\\\4x+60=180\\\\4x=120\\\\x=30

So, the angles measure \boxed{30^{\circ}, 60^{\circ}, 90^{\circ}}

What is (5^-9×5^-2 ÷ 5^-13)^ |7-9| × (5^3 × 5^-5) = ???????
makkiz [27]
The answer is:  "  5⁻ ⁵⁰  " .
__________________________________________
Note that:  |7-9| = <span>| -2 |  =  2 .
__________________________________________
Note:  5</span>³ * 5⁻⁵ = 5⁽ ⁽³⁾ ⁺ ⁽⁻⁵⁾ ⁾ = 5⁽³ ⁻ ⁵⁾ = 5⁻²  ; 
__________________________________________
Note:  (5⁻⁹ * 5⁻² ÷ 5⁻¹³) = (5⁻⁹ * 5⁻²) ÷ 5⁻¹³ ; 

    → (5⁻⁹ * 5⁻²) = 5⁽⁻⁹⁾ ⁺ ⁽⁻²⁾ = 5 ⁽⁻⁹ ⁻ ²⁾ = 5 ⁻¹¹ ;

          →5 ⁻¹¹ ÷ 5⁻¹³  =  5 ⁽⁻¹¹⁾ ⁺ ⁽⁻¹³⁾  = 5⁽⁻¹¹ ⁻ ¹³⁾ = 5⁽⁻²⁴⁾ 
______________________________________________
→ [ 5⁽⁻²⁴⁾ ] ²  = 5⁽⁻²⁴ * ²⁾  = 5⁽⁻⁴⁸⁾ ;
_______________________________________________
  Now, rewrite the entire problem; and solve:
 
 →      5⁽⁻⁴⁸⁾  * 5⁻²  =  5⁽⁻⁴⁸⁾ ⁺ ⁽⁻²⁾  =  5⁽⁻⁴⁸⁻²⁾ ; 

                                                   =  5⁻ ⁵⁰ .
