X-y=34
x+y=338
We can use elimination in this problem.
2x=372
x=186
186+y=338
y=338-186
y=152
Answer:
Yes, Yes, No, Yes.
Step-by-step explanation:
2/5 as a decimal = 0.4
4 ÷ 0.4 = 10
1 is correct.
2 x 10 = 20
2 is correct.
6 x 10 = 60
3 is incorrect.
10 ÷ 2 = 5
4 is correct.
32 x 25 = 800. One strategy you can use is by adding 32 25 times, or adding 25 32 times.
Hope this helps!

Answer:</h3>
C. No, the graph fails the vertical line test
<h3>
Step-by-step explanation:</h3>
Functions describe the relationship between the dependent variable, y, and the independent variable, x.
Functions
For a graph to be a function, x-values cannot repeat. This means that one x-value cannot have more than one y-value.
However, functions can have repeating y-values. So, y-values can have more than one x-value; as seen in quadratic functions. This means that answer B cannot be correct.
Vertical Line Test
The vertical line test is a way to determine if a graph is a function. A graph passes the vertical line test if you can draw a vertical line at every point on the coordinate plane and not have it intersect with the graph more than once.
On the graph in the question, a vertical line would intersect with the graph twice at the x-values greater than -1. Since the graph fails the vertical line test, it is not a function.
