Write an equation where the left side is your power of 10 times n and the right side is the result of multiplying 0.1515... by t

Neko [114]

Answer:

$n10^x = 0.1515x$

Step-by-step explanation:

Required

Translate the statements to algebraic expression

Represent the power with x;

So, the left hand side is

Power of 10: $10^x$

Times n: $10^x * n$

The right hand side is:

0.1515 * power of 10: $0.1515 * x$

Equate the right hand side to the left:

$10^x * n = 0.1515 * x$

$n10^x = 0.1515x$

Hence;

The required expression is $n10^x = 0.1515x$

represents a line that passes through (3, –2) with a slope of negative StartFraction 4 Over 5 EndFraction?

erik [133]

Answer:

$y = \frac{4}{5} x - \frac{22}{5}$

Step-by-step explanation:

$y = mx + b$

$- 2 = \frac{4}{5} (3) + b \\ - 2 = \frac{12}{5} + b \\ - 2 - \frac{12}{5} = b \\ - \frac{10}{5} - \frac{12}{5} = b \\ - \frac{22}{5} = b$

Therefore, the equation of the line that goes through point (3, -2)and has slope ⅘ is

$y = \frac{4}{5} x - \frac{22}{5}$

Number 13 I don’t get it

Nina [5.8K]

<h3>Answer: 1/2 (choice A)</h3>

===========================================

Explanation:

The two equations given to us are

ab = 3
ab^2 = 18

Divide the second equation over the first equation and that would lead to b = 6

Notice how the 'a' terms divide to 1 and go away, i.e. cancel out.

The b terms divide to (b^2)/b = b

The right hand side values divide to 18/3 = 6

So that's how we end up with b = 6

-------------------------

Now if b = 6, then we can say,

ab = 3

a*6 = 3

a = 3/6

a = 1/2

Or we could say

ab^2 = 18

a*6^2 = 18

a*36 = 18

a = 18/36

a = 1/2

Which property can be used to expand the expression -2(3/4x+7)?

Mademuasel [1]

Answer:

Step-by-step explanation:

The distributive property in algebraic terms is

a(b + c) = ab + ac

given the expression

- 2( $\frac{3}{4}$ x + 7) ← multiply each term in the parenthesis by - 2

= - $\frac{3}{2}$ x - 14

Decrease £19064.67 by 9.5% Give your answer rounded to 2 DP.

alina1380 [7]

Answer:

New amount (decrease) = £17253.53

Step-by-step explanation:

Given the following data;

Amount = £19064.67

Percentage = 9.5%

To find the percentage decrease;

$Percentage \; cost = \frac {9.5}{100} * 19064.67$

$Percentage \; cost = 0.095 * 19064.67$

Percentage cost = £1811.14

New amount (decrease) = Original amount - percentage cost

Substituting into the equation, we have;

New amount (decrease) = £19064.67 - £1811.14

New amount (decrease) = £17253.53
