Answer:
(-4,2)
Step-by-step explanation:
First we have to find a common multiple to use to add and find the system of equations. We need to eliminate one of the variables in order to solve.
Since 5 * 3 = 15, and 3 * -5 = 15, -15x and 15x will cancel each other out. Therefore x will be eliminated.
Before:
5x + 2y = -16
3x + 7y = 2
After:
15x + 6y = -48 <----------Now we solve for y
-15x + -35y = -10
+----------------------
-29y = -58
-29 -29
y = 2
Now what we do is we choose and equation and solve for x, since it is still unknown. Any equation is fine but I will choose the second one since it has easy numbers.
3x + 7y = 2
3x + 7(2) = 2
3x + 14 = 2
-14 -14
----------------------
3x = -12
3 3
x = -4
Therefore our final answer is (-4,2)
The straight arrow at the bottom represents 180 degrees.There 3 x's in eqaution so you divide 180 by 3 and you get 60 degrees

Answer:
m(p) = 6p -54
Step-by-step explanation:
Steve has completed 9 problems in class and then he completed problems as homework.
The relation between time spent in minutes(m) in doing homework and the number of the problem solved (p) is given by
......... (1)
Here, p is given in terms of m.
Now, we have to express m in terms of p.
From equation (1), we get m(p) = 6p -54
Here. the number of the problem solved is given as input and the minutes spent in the home to do those problems are obtained as output. (Answer)
