Answer:
-1/2, negative slopeStep-by-step explanation:
As per graph it is visible that the slope is negative, it goes down when x-value increases
Use two points to find the slope:
(-4, -1) and (0, -3)Slope formula:
m = (y2 - y1)/(x2 - x1)Value of the slope:
m = (-3 - (-1))/(0 - (-4)) = -2/4 = -1/2Related Questions

f(0) and f(2) in function notation form
Answers
Answers:
f(0) = 1
f(2) = 5
============================================
Explanation:
Determining f(0)
The y intercept point (0,1) indicates that x = 0 and y = 1 pair up together. Recall that y = f(x), which means f(x) = 1 when x = 0. This is shortened to f(0) = 1.
-----------------
Determining f(2)
Start at 2 on the x axis. Draw an arrow pointing directly upward until you get to the curve. See the diagram below. Then move to the left until you hit the y axis. You should arrive at y = 5.
This tells us x = 2 and y = 5 pair up together. Therefore, f(2) = 5.

Set the equations equal to each other.
4x+3=-x-2
Subtract 3 from both sides
4x=-x-5
Add x to both sides
5x=-5
Divide both sides by 5
x=-1
Next, replace x with -1 in either equation to find y.
-(-1)-2=y
-1=y
3)
Do the same thing for this one and set them equal to each other
-2x+4=-1/3x-1
Add 1 to both sides
-2x+5=-1/3x
Add 2x to both sides
5=5/3x
Divide both sides by 5/3
x=3
Next, replace x with 3 in either equation
-2(3)+4=y
-2=y
Need help will 11&12!
Answers
Answer:
11.)60 degrees the lines on the triangle (the lil dashes) mean that that all the sides are equal making all the angles equal as well so all the angles equal 60 degrees.
12.) no, because in order for all the sides to be 12ft the angles have to be 60 degrees and this one is only 58 degrees so it wont exactly reach 12ft

A display in a grocery store has 120 pieces of fruit. Apples make up 3/5 of the display, and oranges make up 2/5 of the display. If 1/2 of the apples are green, how many green apples are there?
Answers
Answer:
36 green apples
Step-by-step explanation:
First, you should divide 120 by 5 since it is 3:2 and the denominator is 5. Since each part there are 24 fruits, you should now multiply that number by 3 which is 72. Since 1/2 of the apple display are green, you would need to divided 72 by 2 which gets you the answer of 36 green apples.

The Big Time Band put on a community concert. A total of 1,236 people attended the concert. There were twice as many adults as children who attended the concert. How many adults attended the concert?
Answers
Answer:
412 adults
Step-by-step explanation:
Let the number of adults be x
Let the number of children be y
If a total of 1,236 people attended the concert, then;
x + y = 1236 .....1
If there were twice as many adults as children who attended the concert, then;
y = 2x
Substitute y = 2x into 1
x + 2x = 1236
3x= 1236
x = 1236/3
x = 412
Hence 412 adults attended the concert.

N and P are equal to 48 degrees
Step-by-step explanation:
1. 3y^2=12y^2−144
2. Subtract 3y^2 from both sides
3. add 144 to both sides
4. 9y^2= 144
5. Divide both sides by 9
6. y^2 = 16
7. Take the square root of 16 ( which is y=±√16)
8. y = 4 or y = -4
(in this case, Y would equal 4 since the angles are not negative lol)
9. Plug 4 into the equations
10. Compare each answer to see if they are equal
11. submit!
Answer:
∠ N = ∠ P = 48°
Step-by-step explanation:
Δ KMP and Δ LJN are similar ( AA postulate ), then corresponding angles are congruent, that is
∠ P = ∠ N
12y² - 144 = 3y² ( subtract 3y² from both sides )
9y² - 144 = 0 ( add 144 to both sides )
9y² = 144 ( divide both sides by 9 )
y² = 16 ( take the square root of both sides )
y = [tex]\sqrt{16}[/tex] = 4
Then
∠ N = 3y² = 3(4)² = 3(16) = 48² = ∠ P
