Number 15 is the only function on the page because a function is when even input has a different output. so 2 numbers can’t be equal to the same output. 14 is the only one that fits that description. 13 implies that’s it’s not a function bc there are only 3 outputs (1,2, or 3) and there are 4 inputs meaning that every input will not have a different output making it not a function
<span>The answer is the third statement. "The triangles are congruent because triangle R'S'T' is a rotation of triangle RST and rotation in a rigid motion" The triangles are congruent because the image is a rotation (There is a rotation of 180 degrees) of the original and a rotation is a rigid motion. The best way to test it out is to assign values to the points for points R, S, and T and then apply the rule to see where the new image will be. </span>
Answer:
2.5 hours
Step-by-step explanation:
Find unit rate so 1 page per 30 mins. 30 x 5 = 150 minutes. Since it asks for hours, 150/60= 2 hours and 30 minutes or 2.5 hours
First let us represent
x-width
x+3-length
Since it has a width and length, we can say it is a rectangle so the formula for the perimeter of it is 2(l+w)
p=2(l+w)
58=2(x+3+x)
58=(2x+3)2
58=4x+6
52=4x
x=13
the width is 13 and the length is 16
