1906 x 10^3
this is the answer in standard form/ scientific notation
Answer:
Denote that line: y = ax + b
Line passes (-2, 7) and (2,-5):
=> -2a + b =7
=> 2a + b = -5
Add both side of above equations:
=> 2b = 2
=> b = 1
=> a = (-5 - 1)/2 = -3
=> Slope a = -3
Hope this helps!

Answer:
The Musician had $29 before performing at the fairs
Step-by-step explanation:
Let the initial amount musician has be x
At the first musician doubled his money and spent
$30 , this can be written as
2(x) -30---------------------------------(1)
At the second he tripled his money and spent $54.
3(2x -30) - 54
=> 6x-90-54
=> 6x- 144--------------------------------(2)
At the third, he quadrupled his money and spent $72
4( 6x- 144) - 72
24x - 576 - 72
24x -648-------------------------------(3)
At-last he had $48
24x -648 = 48
24x = 48+ -648
24x =696
x = 
x = 29
1 centimeter = 150 centimeters explanation in photo
X = 4.5 x = .5
Step-by-step explanation:
|2x - 5| = 4
The absolute value has two solutions one positive and one negative
2x-5 = 4 2x-5 = -4
Add 5 on each side
2x-5+5 = 4+5 2x-5+5 = -4+5
2x = 9 2x =1
Divide by 2
2x/2 =9/2 2x/2 = 1/2
x = 4.5 x = .5
