Applying the Pythagorean Theorem
Find the lengths of the two sidewalks
Step 1
square section
D=√{15²+15²}
D=√450 m
D=21.21 m
Step 2
rectangular section
D=√{15²+8²}
D=√289 m
D=17 m
Step 3
the sum of the lengths of the diagonals of the two sections is
17m + 21.21 m = 38.21 m
the answer is
38.2 m
The good option to multiply the top equation by is <u>-4</u>
<h3>
REASON :-</h3>
This is because, when we solve the equations, in the left side of first equation :-
☆ -2 can be multiplied by <em>-4</em><em> </em>to get the value 8 on the left side of second equation.
☆ This can help in easier elimination in the given set of equations.
■ The process is to be done as per the given below way :
Now the 8x on both equations can be cut.
Answer:
y = -1x + 3 or f(x) = -1x + 3
Step-by-step explanation:
Rise/run = 3/-3 =<em> <u>-1</u></em>
Crosses the y-axis at <em><u>3</u></em>
y = <em><u>-1</u></em>x + <em><u>3</u></em> or f(x) = <em><u>-1</u></em>x + <em><u>3</u></em>
The x-intercepts of a function are the values of the functions when y = 0.
Given the table below
x f(x)
-4 0
-2 2
0 8
2 2
4 0
6 -2
As can be seen from the table, the y [f(x)] values are 0, when x = -4 and when x = 4.
Therefore, the x-intercepts of the continuous function are (-4, 0) and (4, 0).
answer is A or C hope i helped
