Y= -5x+3 is the equation that is perpendicular to line AB with the point (1,-2)
Supplementary angles is when 2 angles add up to 180 degrees.
We will name the smaller angle a and the bigger angle b.
therefore:
b - 172.6 = a
a + b = 180
Now we substitute:
a + b = 180
b - 172.6 + b = 180
2b - 172.6 = 180
2b = 352.6
b = 176.3
To find a:
a + b = 180
a + 176.3 = 180
a = 3.7
Therefore,
angle a = 3.7 degrees
angle b = 176.3 degrees.
Hope it helps and have a great day ahead
Answe12800 miles
Step-by-step explanation:a year is 12 months, and mile round trip means there and back. so 532x24 for the 24 trips that equals 12768. 12768 rounded to the nearest hundreds is 12800
When using substitution, you want to solve an equation for one variable that doesn’t make the equation worse to work with.
The general idea is that you want to find a variable that has a coefficient of 1 or -1.
In 2.5x - 7y = 7.5, both variables have “bad” coefficients.
In 6.2x - y = 1, the y has a coefficient of -1. That’s where you want to start.
The cost should be the same on day 3
