It is B 80. Because it is 40 x 2 = 80. Hope thishelped
Answer:
See below
Step-by-step explanation:
I can't draw it for you so here are the points. Draw your triangle with them.
From the original triangle, to rotate 180 degrees around the origin, just imagine your are flipping your computer screen upside down which is 180 degrees. To get the coordinates for the points, just make each x and y value the opposite of what the origin is.
Original points ( 2, 1 ) ( 5, -2 ) ( 3, -4 )
Rotated points ( -2, -1 ) ( -5, 2 ) ( -3, 4 )
Answer: (2,11)
Step-by-step explanation:
To find the point where the functions will intersect, we want to find the place that they are equal to each other. We do this by setting the equations equal to each other.
5x+1=-2x+15 [add both sides by 2x]
7x+1=15 [subtract both sides by 1]
7x=14 [divide both sides by 7]
x=2
Now, we know that the functions intersect at x=2. To find the point, we would plug x back into both equations to ensure that the points are the same.
f(2)=5(2)+1 [multiply]
f(2)=10+1 [add]
f(2)=11
The point on f(x) is (2,11).
g(2)=-2(2)+15 [multiply]
g(2)=-4+15 [add]
g(2)=11
The point on g(x) is (2,11).
Since the point at x=2 is the same for f(x) and g(x), we know that the graph intersects at (2,11).
90 × 7 = 630 , it's not hard, it's easy
