X=14 over 5 that's the answer I got when I did it on paper
Answer:
(-1, -2)
Step-by-step explanation:
-9x= 5 - 2y
15x = -11 + 2y => 2y = -11 - 15x
Plug the value for 2y into the first equation.
-9x = 5 - 15x - 11. Solve for x.
-9x = -6 - 15x.
-9x + 15x = -6.
6x = -6.
x = -1.
Now that we found x, we will solve for y.
2y = -11 - 15(-1)
2y = -11 + 15
2y = -4
y = -2.
Thus, our solution set is (-1, -2).
Hope this helps!

Answer:
The 32nd term of the arithmetic sequence is -386.
Step-by-step explanation:
Given: The arithmetic sequence where and
We have to find the 32nd term of the arithmetic sequence.
Consider the given sequence with and
We know , For a given sequence in an Arithmetic sequence with first term and common difference d , we have,
We first find the common difference "d".
, we have,
Solve for d , we have,
-88= 8d
d = - 11
Thus, 32nd term is
Thus, The 32nd term of the arithmetic sequence is -386.
Answer:
When x = 0, then y = -2
When y = 0, then x = 4
Step-by-step explanation:
We are given with the following equation;
x - 2y = 4
Now, we have to find the respective values of x and y for each value of x = 0 and y = 0.
Firstly, putting the value of x = 0;
x - 2y = 4
0 - 2y = 4
-2y = 4
y = = -2
This means that when x = 0, then y = -2.
Similarly, putting the value of y = 0;
x - 2y = 4
x - 0 = 4
x = 4
This means that when y = 0, then x = 4.
