We can rearrange 3x+y=9 to look more conventional by subtracting 3x from both sides and making it y= -3x+9.
Now we want to find a line that is parallel to this and goes through the point (0,-4). We know that -3 is the slope. With this in mind, if we want the other line to be parallel then it must have the same slope so that they never intersect. This gives us one of the numbers we need for the second line.
This means our second equation is looking like; y= -3x+b. This means we need to find b (the y-intercept) but we are also given a point it must go through and this is (0,-4). We simply plug this in into our new equation we need to solve and we get ; -4 = -3(0) + b . "since 0 is the x and -4 is the y" . From this we get that b= -4. This means the equation of a line parallel is:
y = -3x-4

Round the number 4 to 5 because the number 7 is behind it.
Answer:

Step-by-step explanation:
Answer:
x = -9°
m∠A = 37°
Step-by-step explanation:
(8-5x) + (10-3x) = 90
8-5x + 10-3x = 90
18-8x = 90
-8x = 72
x = -9°
m∠A = 10- (-9*3) =
10-(-27) = 37°

The value of the external angle is equal to the sum of the other 2 opostite internal angles
this means that
110=x+60
minus 60 both sides
50=x
x=50 degreees
