Is the inequality always, sometimes or never true?

Feliz [49]

1 ) 9 x + 18 > 9 x - 27
9 x - 9 x > - 27 - 18
0 * x > - 45
Always true
2 ) 6 x - 13 < 9 x - 12
6 x - 6 x < - 12 + 13
0 * x < 1
Always true
3 ) - 6 ( 2 x - 10 ) + 12 x ≤ 180
- 12 x + 60 + 12 x ≤ 180
0 * x ≤ 180 - 60
0 * x ≤ 120
Always true.

What is 36kg in the ratio 7:2

babymother [125]

Answer:

28 Kg : 8 Kg

Step-by-step explanation:

Sum the parts of the ratio, 7 + 2 = 9 parts

Divide 36 Kg by 9 to find the value of one part of the ratio.

36 Kg ÷ 9 = 4 Kg ← value of 1 part of the ratio, thus

7 parts = 7 × 4 Kg = 28 Kg

2 parts = 2 × 4Kg = 8 Kg

36 Kg in the ratio 7 : 2 = 28 Kg : 8 Kg

An experiment observing the growth of two germ strand populations finds these patterns.

Mice21 [21]

Answer:

$R(x) = (1.3)^{3x-8}$

Step-by-step explanation:

Given

$A(x) = (1.3)^{x + 9}$

$B(x) = (1.3)^{4x + 1}$

Required

Ratio B(x) to A(x)

This is calculated as:

$R(x) = B(x) : A(x)$

Express as fraction

$R(x) = \frac{B(x) }{A(x)}$

Substitute: $A(x) = (1.3)^{x + 9}$ and $B(x) = (1.3)^{4x + 1}$

$R(x) = \frac{(1.3)^{4x+1}}{(1.3)^{x+9}}$

Apply law of indices

$R(x) = (1.3)^{4x-x+1-9}$

$R(x) = (1.3)^{3x-8}$
