Answer:
Step-by-step explanation:
- 2x + 3y = -1 is the equation of a line
Pick any values for x then find y or for y and then find x;
if you have two points you can draw a line trough those two points.
For example,
pick x= -1 then find y
- 2*(-1) + 3y = -1
2+ 3y = -1
3y = -1-2
y= -3/3
y= -1
First point has the coordinates (-1, -1)
pick y = 1 then find x
- 2x + 3*1 = -1
-2x +3 = -1
-2x = -1-3
-2x = -4
x= -4/-2
x= 2
Second point has the coordinate (2, 1)
Draw a line trough the points (-1, -1) and (2,1) to sketch the graph of -2x+3y = -1
Let's solve this problem step-by-step.
Let's first establish the following formula:
Angle sum of a triangle = 180°
Also, note that the square shape in the top-right corner of the triangle indicates that it is a right-angle. This means that, that angle is equal to 90°.
Now, let's establish the equation we will be using to solve this problem based on the previous information as displayed below:
m + 38° + 90° = 180°
We will now simply solve the equation in order to obtain the value of ( m ) as display below:
m + 38° + 90° = 180°
m = 180 - 38 - 90
m = 52°
ANSWER:
Therefore, the answer is:
C. 52 degrees.

I won’t Tell you the answer but I can tell you how to do it, so take 16 3/4 and divide it by 4 and you get your answer.
First do the multiplication inside the parenthesis
(-y+15) + (7.2y-9)
Remove the parenthesis now
-y+15+7.2y-9
Simplify:
6.2y +6
So your final answer is
