While you cannot solve 946x+642y=911 for numerical values of x and y, you can indeed solve 946x+642y=911 first for x and then for y:
-911 - 642y
For x: 946x+642y=911 becomes 946x = 911 - 642y, or x = ------------------
946
911-946x
For y: 946x+642y=911 becomes 642y = 911-946x, or y = ---------------
642

Answer:
3042 in³
Step-by-step explanation:
The dimensions of the water are ...
19.5 in long × 12 in wide × 13 in tall
The volume in cubic inches is ...
V = LWH
V = (19.5 in)(12 in)(13 in) = 3042 in³
_____
At 231 cubic inches per gallon, that's about 13.17 gallons.
2x - 14y = -16
Move all the terms without the variable on the other side of the equation. Add 14y to both sides of the equation.
2x = -16 + 14y
Divide both sides by 2.
x = -8 + 7y is your answer.
Answer:
slope = 2
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 )
Given
x + 2y = - 16 ( subtract x from both sides )
2y = - x - 16 ( divide all terms by 2 )
y = - 
x - 8 ← in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= 2
