Answer:
<h2><u>(9, 76)</u></h2>Step-by-step explanation:
y = 7x + 13
y = 3x + 49
================
We can solve this in either of two ways: Mathematically and graphically.
<h2><u>Math</u></h2>Set the equations equal to each other (after all, y does equal y).
7x + 13 = 3x + 49
4x = 36
x = 9
Then use x = 9 to solve for y:
y = 7x + 13
y = 7(9) + 13
x = 76
<h2><u>Graph</u></h2>Plot the two equations. I use Desmos - its online and free. The intersection of the two lines reveals to answer: (9,76). See the attachment.
Answer:
Step-by-step explanation:
Sides of the figure = n = 7
<h3><u>Formula for measuring the interior angles of a polygon:</u></h3>(n - 2)×180
Where n is the number of sides in the polygon
So,
<h3><u>Measure of interior angles in the figure:</u></h3>= (n - 2) × 180
= (7 - 2) × 180
= 5 × 180
= 900
