2/17+3/7(3x−5)=−4 What is the solution?

Zanzabum

2/17 + 3/7(3x - 5) = -4
2/17 + 9/7x - 15/7 = -4...multiply by LCD of 119 to get rid of fractions
14 + 153x - 255 = - 476
-241 + 153x = -476
153x = -476 + 241
153x = - 235
x = -235/153

Answer:

$a = 73.84$ , $b = -23.64$ , $c = 83.97$ , $d = 21.73$

Step-by-step explanation:

1880:

The predicted value is:

$f(80) = 1.363\cdot (80) - 35.2$

$f(80) = 73.84$

The residual value is:

$\Delta f = 50.2 - 73.84$

$\Delta f = -23.64$

1920:

The predicted value is:

$f(120) = 7.8 \cdot 1.02^{120}$

$f(120) = 83.97$

The residual value is:

$\Delta f = 105.7 - 83.97$

$\Delta f = 21.73$
