$11.01 is your rate of pay
Answer:
The solution is x = -2, y = -3
Step-by-step explanation:
Let's start with the equation 3x + y = -9
Substitute the y for 5x+7 seen in the second equation
Now you have 3x + (5x+7) = -9
Lets solve:
Let's add the x's
Now we have 8x + 7 = -9
Substracy seven from each side
Now we have 8x = -16
Now let's divide 8 on each side
Now we have x = -2
Now lets plug in -2 to the second equation
The second equation is y = 5x+7
When we plug in -2 we get y=5(-2)+7
We multiply
We now have y = -10+7
Add
y = -3
The solution is x = -2, y = -3
Answer:
y - 3 = - 4 ( x + 4)
Step-by-step explanation:
(-4,-3) and (4,1)
Slope = (1 + 3)/(4 + 4) = 2/8 = 1/4
Perpendicular lines, slope is opposite and reciprocal so slope of the line that is perpendicular to the given line is -4
Equation in point slope form, passing thru (-4 , 3)
y - 3 = - 4 ( x + 4)
Answer: 900 degrees
Step-by-step explanation:
The formula for the sum of the interior angles is (n-2)*180 where n is the number of sides.
In this case, there are 7 sides so the sum of the interior angles would be
(7-2)*180
= 5*180
= 900 degrees
