<u>2x - 3</u> = <u>2x - 4</u>
2 - x 1 - x
(2x - 3)(1 - x) = (2x - 4)(2 - x)
2x(1 - x) - 3(1 - x) = 2x(2 - x) - 4(2 - x)
2x(1) - 2x(x) - 3(1) + 3(x) = 2x(2) - 2x(x) - 4(2) + 4(x)
2x - 2x² - 3 + 3x = 4x - 2x² - 8 + 4x
-2x² + 2x - 3 + 3x = -2x² + 4x - 8 + 4x
-2x² + 2x + 3x - 3 = -2x² + 4x + 4x - 8
-2x² + 5x - 3 = -2x² + 8x - 8
<u>+ 2x² + 2x² </u>
5x - 3 = 8x - 8
<u> - 5x - 5x </u>
-3 = 3x - 8
<u>+ 8 + 8</u>
<u>-5</u> = <u>3x</u>

-1²/₃ = x
Answer:
Option A.
Step-by-step explanation:
step 1
we know that
The equation of the solid line is

The solution is the shaded area above the solid line
so
The equation of the first inequality is

step 2
The equation of the dashed line is

The solution is the shaded area above the dashed line
so
The equation of the second inequality is

therefore
The system of inequalities could be

Answer:
hello your question is incomplete attached below is the complete question
answer :
a ≈ - 136
b = 2.46
Step-by-step explanation:
A) we apply the formula for slope in regression
b = r *
--------- ( 1 )
where:
standard deviation (Sy) = 27.8913
standard deviation ( Sx ) = 11.2921
Linear correlation coefficient ( r ) = 0.9972
substitute given values into equation 1
b = 2.46
for intercept A
a = Y - b * X --------- ( 2 )
Mean number of ice bags sold ( Y )= 70.2873
b = 2.46
Mean temperature ( X )= 83.8959
substitute given values into equation 2
a = 70.2873 - ( 2.46 * 83.8959 )
= - 135.997
