First, you want to get it looking like y = mx + b, the original formula.
In y = mx + b, m = slope and b = y-intercept.

-3y + 21x = 15
(isolate the y, move the x to the right)
-3y = -21x +15
(isolate the y, divide by -3)
y = 7x - 5

Therefore, the slope is 7 and the y-intercept is -5.

17n + 4n- 4= 122<br><br> how do i solve for n?

Leokris [45]

Answer:

n = 6

Step-by-step explanation:

17n + 4n - 4 =122

combine like terms 17n & 4n

21n - 4 = 122

21n - 4 + 4 = 122 + 4

21n = 126

21n / 21 = 126 / 21

n = 6

Can someone help me out with this please? I suck at fractions

164 inches x $\frac{1 foot}{12 inches}$ = $\frac{41}{3}$ ft

147 inches x $\frac{1 foot}{12 inches}$ = $\frac{49}{4}$ ft

2 $\frac{1}{4}$ ft = $\frac{9}{4}$

Perimeter = 2L + 2w - 1doorway

= 2 $(\frac{41}{3})$ + 2( $(\frac{49}{4})$ - $\frac{9}{4}$

= $\frac{82}{3}$ + $\frac{98}{4}$ - $\frac{9}{4}$

= $\frac{82}{3}$ + $\frac{89}{4}$

= $(\frac{4}{4} )$ $\frac{82}{3}$ + $(\frac{3}{3} )$ $\frac{89}{4}$

= $\frac{328}{12}$ + $\frac{267}{12}$

= $\frac{595}{12}$

= 49 $\frac{7}{12}$ ft

******************************************************************************

b) 49 $\frac{7}{12}$ ft ÷ 8ft = 6.2
