<span>4x + 8y = −8
8y = -4x - 8
y = -1/2x - 1
</span>⇒ Slope = -1/2
⇒ Slope of perpendicular line = 2
<span>
- </span><span>4x + 2y = - 6
2y = 4x - 6
y = 2x - 3
</span>⇒ y-intercept = -3
<span>
</span><span>Equation:
y = mx + b
Substitute the value for the slope and y-intercept:
y = 2x - 3
Answer: </span> y = 2x - 3
<span>Continuous functions of time are a function if small changes are made to the source then the result will have those small changes in them.
The quantity of gas is a continuous function of time because small variations can be made to the quantity of the gas in use to the extent of molecules and atoms whereas same cannot be done to the student as we cannot half them.</span>
Answer:
(x+1)²-64 is that equation using complete the square
Solve the system of linear equations. 9x-19y=74 and 3x+3y=6<span>3x+3y=6
Solve equation #2 for x
3x = 6-3y
x = 2-y
</span>Plug x above in equation #1 to find y
<span>9x-19y=74
</span><span>9(2-y) - 19y = 74
18 - 9y -19y = 74
-28y = 74 - 18
-28y =56
y =56/(-28)
y = -2
plug y = -2 into </span>x = 2-y to look for x
<span>
x = 2 -(-2)
x = 2 +2
x = 4
OK answer x = 4 and y = -2
{x, y} = {4, -2}
