Step-by-step explanation:

Well it doesn't help you very much, but the answer is A. What this does is separates 7/8 x so that (x/8) sits by itself. After you subtract 3/4 from both sides, you can divide both sides by 7. When you do that, you get x/8 = something, but the fractions are going to be awkward at best. I'll just do a very quick run through

7(x/8) = -6 - 3/4

7(x/8) = - 6.75                     Divide by 7

x/8 = 0.9642                      Multiply by 8

x = 8 * 0.9642

x = 7.7143

Answer:

2 and 10

Step-by-step explanation:

6+4=10, and 6-4=2.

The number four units away from 6 are 2 and 10 and are represented below the number line.

The number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.

A horizontal number line is the most common representation and can be extended infinitely in any direction.

Given that,

Four units away from 6

Four units higher →

6 + 4 = 10

Four units lower →

6 - 4 = 2

In the below number line, it is shown diagrammatically.

Hence "The number four units away from 6 are 2 and 10 and are represented below the number line".

Answer:

If i am right i think its 1419

Step-by-step explanation:

3250/2.29= about 1419

Answer:

1419.21= 1419

Step-by-step explanation:

Divide the amount of money you have with the cost price of what you want to buy.

$3250/$2.29=1419.213974

The answer is a decimal. But we can not have a unit as decimal so we have to round it down to the nearest whole number.

Therefore = 1419

Answer:

[tex]h(x) = 10[/tex]

Step-by-step explanation:

Given

[tex]h(x) = |2x| - 4[/tex]

[tex]x = -7[/tex]

Find h(x)

Substitute -7 for x

[tex]h(x) = |2*-7| - 4[/tex]

[tex]h(x) = |-14| - 4[/tex]

Absolute values return positive. So:

[tex]h(x) = 14 - 4[/tex]

[tex]h(x) = 10[/tex]

Answer:

D. y = x - 4

Step-by-step explanation:

Given the following data;

Points (x, y) = (3, -1)

To find the equation of line;

First of all, we would determine the slope of the graph.

Mathematically, slope is given by the formula;

[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]

[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Substituting into the equation, we have;

[tex] Slope, m = \frac {5 - 5}{5 - 5} [/tex]

Slope, m = 1

Generally, the equation of straight line is y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

Substituting the values in order to find the intercept, we have;

Using points (x, y) = (3, -1)

-1 = 1*3 + c

-1 = 3 + c

c = -1 - 3

Intercept, c = -4

Therefore, the equation of line becomes;

y = x - 4.

A large aquarium has a length of 84 inches. It is located in a large basement that is properly heated and ventilated. The width should be close to 1/2 the length and the height ought to be 1/6 the length. If the fish tank requires that an aerator be placed every 28 inches along the back edge, how many aerators are needed. Note: an aerator is not placed in either corner.

The expressions that is equivalent to log (12/5) would be A. log (12) - log (5).

When you raise a number with an exponent, there comes a result.

Lets say you get

a^b = c

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

b = \log_a(c)

'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'

We have given an expression as ;

log (12/5)

We know that

[tex]log_a(b) - \log_a(c) = \log_a(\frac{b}{c})[/tex]

So,

log (12/5) = log (12) - log (5)

Thus, the correct option is A. log (12) - log (5)

The expressions that is equivalent to log (12/5) would be A. log (12) - log (5).
