Answer:
x = 3/2 - 5y/4
Step-by-step explanation:
5y + 4x = 6
-5y -5y
4x = 6-5y
/4 /4 /4
x = 6/4 - 5y/4
x = 3/2 - 5y/4
Move all terms that don't contain x to the right side and solve.
It would be 80 fives & 44 tens.
80 fives is $400 and 44 tens is $440.
(0,2)(-2,0)
slope = (0 - 2) / -2 - 0) = -2/-2 = 1
(0,2)...x = 0 and y = 2
sub and find b, the y int
2 = 1(0) + b
2 = b
equation is : y = x + 2......solid line, means there is an equal sign....shaded below the line means less then....
ur inequality for this line is : y < = x + 2
(0,6)(3,0)
slope = (0 - 6) / (3 - 0) = -6/3 = -2
y = mx + b
slope(m) = -2
(0,6)...x = 0 and y = 6
sub and find b, the y int
6 = -2(0) + b
6 = b
ur equation is : y = -2x + 6....dashed line means there is no equal sign...and shading below the line means less then...
so ur inequality of this line is : y < -2x + 6
In summary, ur 2 inequalities are : y < = x + 2 and y < -2x + 6
The answer for the exercise shown above is the second option, which is: <span>
Maximum: 32°; minimum: −8°; period: 10 hours. The explanation is shown below:
</span> You can make a graph of the function given in the problem above: f(t)=20Sin(π/5t)+12.
As you can see in the graph, the maximum point is at 32 over the y-axis, and the minimum is at -8.
The lenght of the repeating pattern of the function (Its period) is 10.
