Answer:
5
Step-by-step explanation:
1 ounce = 0.0625
0.0625 x 80 = 5
Answer:
![\huge\boxed{(12,80),(10,65)}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7B%2812%2C80%29%2C%2810%2C65%29%7D)
Step-by-step explanation:
The line given has a slope of 7.5 and a point at (12, 80)
Because of the slope, simply subtract 2 from the x and subtract 15 from the y to get another point, at (10, 65)
Thus, simply put your points at (10, 65) and (12, 80)
Hope it helps and let me know if you want me to elaborate.

Hello :
(x+4)/(4+x) = (x+4)/(x+4) = 1 ( answer : C ) but x+4 no : 0
$9.50 plus sales tax would be $0.95 so $10.45
Answer:
7x + 3y = 44
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 )
Rearrange - 3x + 7y = 5 into this form by adding 3x to both sides
7y = 3x + 5 ( divide all terms by 7 )
y =
x +
← in slope- intercept form
with slope m = ![\frac{3}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B7%7D)
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute (5, 3) into the partial equation
3 = -
+ c ⇒ c = 3 +
= ![\frac{44}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B44%7D%7B3%7D)
y = -
x +
← in slope- intercept form
Multiply through by 3
3y = - 7x + 44 ( add 7x to both sides )
7x + 3y = 44 ← in standard form
