Perimeter is legnth +legnth + width + width or
P=2L+2W
L=2W
subsitute L=2W for L in P=2L+2W
P=2(2W)+2W
P=4W+2W
P=6W
we know that Perimiter=30 so
30=6W
divide both sides by 6
5=Width
subsitute W=5 for W in L=2W
L=2(5)
L=10
to check
10=2(10)+2(5)
30=20+10
30=30
checks
Legnght=10
Width=5

Your answer would be C and D, the domain for this function is all real numbers, and the range for this function is the set {-5}.
C is correct: The domain of a function is the amount of x values. For example, if you had a line going from an x value of 1 to an x value of 3, the domain would be {1<x<3}.
In this case, C is stating the domain of this function is all real numbers. This is true, because the straight line will continue for all values of x, so therefore the domain is all values of x, or all real numbers.
D is correct: The range is the exact opposite of a domain of a function. It is the number of y values the function covers.
In this case, D is stating the range is {-5}. This is correct, because the straight line only covers the y value of -5, so therefore that is the range.
A is therefore incorrect because the domain has already been established as all real numbers. B is incorrect because a horizontal line is a function, and one value of y can have multiple values of x. E is incorrect because the range has already been established as only one number.
Good luck!
Answer:
Distance between nina's house to her friend's home = AC = 5 miles
Step-by-step explanation:
Distance between nina's house to her school = BC = 4 miles
Distance between nina's school to her friend's home = BA = 3 miles
Distance between nina's house to her friend's home = AC = ??
From the ΔABC
AC = 5 miles
Therefore Distance between nina's house to her friend's home = AC = 5 miles
Well since we’re given 2 angles, 62 and 58, we have enough information to solve the problem.
Since any triangles angles always add up to 180 degrees, we can simply add up 62 and 58 then subtract from 180.
62
+58
———
120
Now to find the last angle of the triangle you have to subtract 120 from 180 which is 60 degrees. This means x = 60.
However we’re not done, with this 60 we can now calculate y. Since the line is a 180 angle line! We can just subtract 60 from 180 which gives us 120.
The angle of y is 120
