Answer:\frac{1}{2}

Step-by-step explanation:

With unlike denominators find the Least Common Denominator (LCD)

LCD = 12

Multiplying numerators and denominators to get the LCD in all fraction denominators

=\frac{3x3}{4x3}-\frac{1x4}{3x4}+\frac{1}{12}

Then rewriting the equation with the equivalent fractions

=\frac{9}{12}-\frac{4}{12}+\frac{1}{12}

With like denominators we can operate on just the numerators

=\frac{9-4+1}{12} =\frac{6}{12}

Simplifying the answer

=\frac{1}{2}

How would you simplify (log 27/logx) x (log x^2/log3)? I don’t think I did this correctly.
Kaylis [27]

Answer:

6

Step-by-step explanation:

logx 27  * log3 x^2

The first step is to convert to base 10

(log 27/logx) * (log x^2/log3)

27 = 3^3 so we can rewrite this

(log 3^3/logx) * (log x^2/log3)

log a^b  = b log a

(3 log 3/logx) * (2log x/log3)

We can cancel the log x in the numerator and denominator and the log 3 in the numerator and denominator

3 * 2

A graphic designer chose a base font size and represented it as 1 on the scale. he then listed some consecutive scale sizes. two
garik1379 [7]

Answer:

3.24

Step-by-step explanation:

You would use the two fonts given to find the scale factor.

So the scale factor would be 10.4976/5.832 = 1.8

So if the scale factor is 1.8 we can use that to find the font size just before that. To do this you would divide the font size by the scale factor.

So

5.832/1.8 = 3.24

The font size just before 5832 is 3.24.

Hope this helps, if there is an error in my work please correct me.

A line passes through (1, -5) and (-3, 7).
siniylev [52]

Answer:

Slope-intercept form: y=-3x-2

Point-slope form: y+5=-3(x-1)

Step-by-step explanation:

Slope-intercept form is y=mx+b

Point-slope form is y-y1=m(x-x1)

The slope is (7-(-5))/(-3-1)=12/-4=-3

Now we solve for b, aka. the y-intercept:

-5=-3(1)+b

-5=-3+b

-2=b

So the equation in slope intercept form is y=-3x-2

As for point-slope form, it's y+5=-3(x-1)

Write the steps to get the given answer, then check:<br> -4(m + 3)=24<br><br><br> m=-9
Mariana [72]

Answer:

m= -9

Step-by-step explanation:

-4(m+3)=24

Use distributive Property:   -4m-12=24

Add 12 to both sides: -4m=36

Divide both sides by -4: m=-9

You can check the answer by plugging -9 into m on the original equation.
