Answer:
A - ASA
B - ASA
C - SAS
D - SSS
Step-by-step explanation:
I hope this helps you out!
41.2 cm
Step-by-step explanation:
subtract the y's and x's to get the distances
left & right sides are hypotenuses
top :
10 - (-2) = 12
bottom :
5 - (-7) = 12
left :
3 - (-4) = 7 = height
-7 -(-2) = -5 = 5 = base
pythagorean theorem
49 + 25 = 74
square root of 74 = 8.6
right :
same
perimeter :
12 + 12 + 8.6 + 8.6 = 41.2
Hey there!
A function is a relation to numbers in which an input value as a specific output value.
a) Is a function. All x values go to specific y values. For domain, look at the x values. You go from 2 to 8. So, 2≤x≤8 (we can assume the line just goes this long since we are not given anymore information) For the range, we have the same thing. It goes from 5 to 8. 5≤y≤8
b) Is not a function. 1 cannot go to two y-values.
c) Is not a function. Does not pass vertical line test.
d) Is a function. Passes the vertical line test. For the domain on this one, it would be infinite, which you could represent as (-∞,∞) It is infinite because the line as two arrows that continue forever. For the range, it would be anything greater than 2. y≥2 or 2≤y
The question stated you only needed to find the domain and range for the functions, so you would just do it for a) and d).
I hope this helps!
