Answer:

Step-by-step explanation:

1. X/2 when x = 1/2

Putting value of x in the equation

1/2 /2 = 0.25

2. 2x2 - 8 when x = 3

2(3)2 - 8

= 2(9) - 8

= 18 - 8 = 10

3. 4(x - 7)3 + 5 when x = 9

4 (x3 - 21x2 + 147x - 343) + 5

Putting value of x

4((9)3 - 21(9)2 + 147(9) - 343) + 5

4(729 - 1701 + 1323 - 343) + 5

4(8) + 5

= 32 + 5 = 37

Solve the equation.<br> -3x +.1 + 10x = x + 4<br> N<br> olu<br> R<br> X =<br> 18
zheka24 [161]

Answer:

Hence after solving the given equation we get <em>x = 13/20.</em>

Step-by-step explanation:

<em>Given:</em>

<em>-3 x + 0.1 + 10 x = x + 4</em>

<em>-3 x + 10 x - x = 4 - 0.1</em>

<em>6 x = 3.9</em>

<em> x = \frac{3.9}{6}</em>

<em>x = \frac{1.3}{2}</em>

<em>x = \frac{13}{20}</em>
