Answer:
x= 7, y= -7 or (7, -7)
Step-by-step explanation:
3x-y=28
3x+y=14
because the y is opposite of each other in both equations you can cancel them out
3x=28
3x=14
next you add 3x to 3x, then 28 to 14 and get...
6x=42
next divide both sides by 6 and you get your answer for x...
x=7
now you must solve for y and you do this by substituting what you found for x in one equation it doesn't matter which because you'll get the same answer but you can check for both to make sure...
3(7)+y=14
21+y=14
y=-21+14
y=-7

Answer:
74 °
Step-by-step explanation:
the sum of every angle from a triangle is 180
so to find b is add 80 with 26 which is 106
then subtract 180 with 106
the final answer is 74
Answer:
The answer to your question is No
Step-by-step explanation:
To answer this question use the Vertical line test. This test states that if we draw a vertical line and intercepts the function only in one point it is a function.
It the vertical line intersects the graph in two or more points, it is not a function.
See the picture below
The graph given is not a function because the vertical line crosses the graph in three points.
The circle graph is usually used to show proportions of a whole.
The Venn Diagram is used to represent the relationship between two or more collection of objects.
The double bar graph is used to compare two variables over a period of time.
The line graph is used to compare the trends of a variable over a period of time.
Therefore, the <span>graphical representation that would best display the number of points a home team and a visitor’s team scored in each game this season is the double bar graph.</span>
