Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 8 and c = - 5, thus

y = 8x - 5 → B

Answer:

Step-by-step explanation:

y = mx + b

m represents slope and b is the y intercept

so 8x is mx in this equation and -5 is b

Afina-wow [57]

Answer:

$d)\ \frac{81}{m^{7}}$

Step-by-step explanation:

$(3m^-4)^3(3m^5)$

First, simplify $(3m^{-4})^3$ :

$(3m^{-4})^3\\\\3^3*m^{-4*3}\\\\27m^{-12}$

$27m^{-12}*3m^5\\\\27*3 *m^{-12+5}\\\\81m^{-7}\\\\81*\frac{1}{m^{7}} \\\\\frac{81}{m^{7}}$

Hope this helps!

Reba measured a house and its lot and made a scale drawing. She used the scale 9 inches = 7 feet. What is the scale factor of th

Otrada [13]

The scale factor of the Reba's drawing is 9/84, 3/28

Step-by-step explanation:

The scale factor is the ratio between the two corresponding sides of the figure. The point worth noting in computing the scale factor is that both sides must have similar units of dimension while using for comparison purpose.

Given the scale used by Reba is 9 inches to 7 feet

Since both the units are different, we have the option to either convert inches to feet or vice versa

We proceed with converting feet to inches

We know that 1 foot equals to 12 inches. Hence 7 feet would equal 84 inches.

Now scale factor= first dimension/ corresponding dimension

Scale factor= 9/84 which can be reduced to 3/28
