Identifying the domain and range of the relation.
Answer:
1. The domain is (-2, -1, 0, 1) the rage is (4,2,0,2) 2. It is a function
Step-by-step explanation:
The domain in a pair is always the first number. The range is always the second number in the ordered pair.
Answer:
Domain: {−2,−1,0,1}
Range: {0,2,4}
Step-by-step explanation:
The domain is all the x-coordinates, but NEEDS TO BE ORDERED, which are {−2,−1,0,1} and you also need to include the curly brackets { }.
The range is all the y-coordinates and also NEEDS TO BE ORDERED, which are {0,2,4} and you also still need to include those curly brackets { }.

(PLEASE ANSWER!) Two distinct lines, L and M, are each perpendicular to the same line N. What is the measure of the angle where line L meets line N? What is the measure of the angle where line M meets line N?
Answer:
90 and 90
Step-by-step explanation:
If they are perpendicular it means they cross at a 90 degree angle so since both L and M are perpendicular to N both the answers would be 90
Hope This Helps :)
The measure of the angle where line L meets line N is 90° ;
and the measure of the angle where line M meets line N is 90°.
What are perpendicular lines?In geometry, perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).
Now it is given that,
Two distinct lines, L and M, are each perpendicular to the same line N.
Line L is perpendicular to line N.
Since angle between two perpendicular lines = 90°.
So, angle between line L and line N = 90°
Similarly, Line M is also perpendicular to line N.
Therefore, angle between line M and line N = 90°
Thus, The measure of the angle where line L meets line N is 90° ;
and the measure of the angle where line M meets line N is 90°.

The number of students, SSS, serviced by the school system in the town of Emor, ttt years from 2000 can be modeled by the function S(t)=10{,}000(1.1)^t. The number of classrooms, C, in the town of Emor, t years from 2000 can be modeled by the function C(t)=450+40t. Let D be the average number of students per classroom in Emor's school system t years from 2000.
Answer:
The formula of D (t) is .1000.(1.1)/45+4t
Step-by-step explanation:
The expression representing the number of students serviced by the school system in the town of Emor, t years from 2000 is:
And the expression representing the number of classrooms in the town of Emor, t years from 2000 is: s(t)=10,000.(1.1)^t
The expression D (t) represents the average number of students per classroom in Emor's school system t years from 2000.
Then the average number of students per classroom can be computed by:
C(t)=450+40t.
Average number of students/classroom = Number of students/Number of classrooms so the answer is D (t) .1000.(1.1)/45+4t
Thus,the formula of D (t) is .
Which of these triangle pairs can be mapped to each other using a single reflection?
Triangles F E G and F G L are congruent. Triangle F E G is reflected across line F G to form triangle F G L.
Triangles F E G and G L M are congruent. Triangle E F G is rotated about point G to form triangle G L M.
Triangles F E G and L M N are congruent. Triangle F E G is shifted down and to the right to form triangle L M N.

The slope of the line that represents the data Nicholas collected is -63, and the y-intercept is 825. Explain what these represent in the context of the situation. Remember that x is the number of days, and y is the number of canned goods. The slope of the line that represents the data Nicholas collected is -63, and the y-intercept is 825. Explain what these represent in the context of the situation. Remember that x is the number of days, and y is the number of canned goods.
Answer:
slope of - 63 in the context means, as the number of days increases by 1, The number of canned goods there is 63 reduction in yhe number of canned goods.
An intercept value of 825 means the Number of canned goods even when the number of days is 0.
Step-by-step explanation:
Given that:
Slope = - 63
y intercept = 825
x = number of days
y = number of canned goods
From the general form of a linear model :
y = mx + c
m = slope / gradient ; c = intercept
Hence,
y = - 63x + 825
A slope of - 63 in the context means, as the number of days increases by 1, The number of canned goods there is 63 reduction in yhe number of canned goods.
An intercept value of 825 means the Number of canned goods even when the number of days is 0.
Answer:
The slope indicates that the soup kitchen uses 63 cans per day. The y-intercept shows that there were initially 825 cans at the soup kitchen.

1/2z+6=3/2(z+6) need the answer asap
Answer:
z = -3
Step-by-step explanation:
[tex]\frac{1}{2}[/tex]z+6 = [tex]\frac{3}{2}[/tex](z+6)
Expand and cancel out brackets.
[tex]\frac{1}{2}[/tex]z+6 = [tex]\frac{3}{2}[/tex]z +
Simplify.
[tex]\frac{1}{2}[/tex]z+6 = [tex]\frac{3}{2}[/tex]z + 9
Isolate x and numbers.
[tex]\frac{3}{2}[/tex]z - [tex]\frac{1}{2}[/tex]z = 6-9
Simplify.
[tex]\frac{2}{2}[/tex]z = -3
z = -3
Answer:
z=−3
Step-by-step explanation:
1/2*z+6-(3/2*(z+6))=0
Simplify 3/2
1 3
((— • z) + 6) - (— • (z + 6)) = 0
2 2
Simplify 1/2
Rewrite the whole as 6.1 Pull out like factors :
-2z - 6 = -2 • (z + 3) a fraction using 2 as the denominator.
-z - 3 = 0
7.1 Solve : -z-3 = 0
Add 3 to both sides of the equation :
-z = 3
Multiply both sides of the equation by (-1) : z = -3

Answer:
b
Step-by-step explanation:
Helpppppppp asap please with calculations pls pls pls
Answer:
For the first one it is y = -5x because for it to be direct it can't have a b-intercept. it must start at 0.
Second question: y2 - y1/x2 - x1
13-(-8)/(-4)-3
21/(-7)
-3 is the slope
y= -3x + b
13 = -3(-4) + b
13 = 12 + b
12 - 13 = b
b = -1
y=-3x-1
0 = -3x - 1
1 = -3x
1/-3 = -3x/-3
x= -1/3
y=-3x-1
y=-3(0)-1
y= -1
The answer to the 3rd question is y = 1x + 2 because the rise over run is one and the line crosses the y-intercept at 2.
I am not sure if these answers are correct.
