Answer:

x = 11.7

Step-by-step explanation:

We have the following equation: -4.5(x-8.9)=12.6

First we divide both parts of the equation by -4.5

Then: (-4.5(x-8.9))/-4.5 = 12.6/-4.5

We get: (x-8.9) = 2.8

Then, solving for x:

(x-8.9) = 2.8 -> x = 2.8 + 8.9 = 11.7

The solution is: x = 11.7

3. For the following geometric sequence, determine a1 and r and find an explicit formula for the sequence: 2, -6, 18, -54…

Vilka [71]

Step-by-step explanation:

a1 is the first term. In this case, 2.

r is the common ratio. Each term is multiplied by -3 to get the next term, so r = -3.

Rectangle ABCD was dilated to create rectangle A'B'C'D. Triangle A B C D is dilated to form triangle A prime B prime C prime D.

Julli [10]

Answer:

$AB = 6$

Step-by-step explanation:

Given

$BC = 3.8$

$A'B' = 15$

$B'C' = 9.5$

Required

Determine the length of AB

Because A'B'C'D is a dilation of ABCD, then the following relationship must exist:

$A'B' : AB = B'C' : BC$

Substitute values for A'B', B'C' and BC

$15 : AB = 9.5 : 3.8$

Express the ratio as fractions:

$\frac{AB}{15} = \frac{3.8}{9.5}$

Multiply through by 14

$15 * \frac{AB}{15} = \frac{3.8}{9.5} * 15$

$AB = \frac{3.8}{9.5} * 15$

$AB = \frac{3.8* 15}{9.5}$

$AB = \frac{57}{9.5}$

$AB = 6$
