Which graph represents this system?y=3 x+y=4
2 answers:
Answer:
The graph that represents the system is:
A graph that for y = 3 cuts the axis at point 3 and for x + y = 4 cuts the graph in the coordinates (0, 4), (1, 3), (2, 2), (4, 0) and others that comply with the rule that when added they give a value of 4.
<em>Exact graph as an annex.</em>
Step-by-step explanation:
As you can identify in the graph that is in the annex, the fragment <u>y = 3</u> (differentiated with red color in the graph) refers to the fact that the Y-axis is going to be cut at point 3 with a continuous horizontal line, while the fragment of the system <u>x + y = 4</u> (differentiated with blue color in the graph) refers to all those values of X and Y that when added together give a value of 4, in the answer I have given you the examples that more are denoted in the graph, but you can take others like (5, -1) since if you add them:
- -1 + 5 = 4
The final value of 4 given by the equation is still maintained.

answer :
Mark the point of intersection S of circles R and P, and construct line QS ( option 2 )
Step-by-step explanation:
when constructing a tangent line from one point ( lets say Q as seen in the question ) to a circle P. The next step should be to mark a point of intersection between the given circles and then construct a line through it
The formula for the area of a triangle is:
where B is the base of the triangle and h is the height
It appears that the height of the triangle is 5 units (not quite 4.5) and the base is 10 units.
Multiply these to get 50, and divide by 2 to get 25.
The area of the triangle should be 25 u²
Hope this helps! :)
