(100 points) Match each ordered pair on the left with the functions on the right
Answers
Answer:
(6, 1) ⇒ y = 2/4x - 2
(-8, -0.8) ⇒ y = 3/5x + 4
(9, 0.7) ⇒ y = 3/10x - 2
(2, 7.4) ⇒ y = 1/5x + 7
Step-by-step explanation:
Let's substitute each pair in the equations to find the right one :
(6, 1)
⇒ 1 = 2/4 (6) - 2
⇒ 1 = 3 - 2
⇒ 1 = 1
⇒ Equation matched √
(6, 1) ⇒ y = 2/4x - 2
(-8, -0.8)
⇒ -0.8 = 1/5 (-8) + 7
⇒ -0.8 = -8/5 + 7
⇒ -0.8 = -1.6 + 7
⇒ -0.8 = 5.4
⇒ Incorrect equation ×
⇒ -0.8 = 3/5 (-8) + 4
⇒ -0.8 = -24/5 + 4
⇒ -0.8 = -4.8 + 4
⇒ -0.8 = -0.8
⇒ Equation matched √
⇒ (-8, -0.8) ⇒ y = 3/5x + 4
(9, 0.7)
⇒ 0.7 = 3/10 (9) - 2
⇒ 0.7 = 27/10 - 2
⇒ 0.7 = 2.7 - 2
⇒ 0.7 = 0.7
⇒ Equation matched √
⇒ (9, 0.7) ⇒ y = 3/10x - 2
(2, 7.4)
⇒ 7.4 = 1/5 (2) + 7
⇒ 7.4 = 2/5 + 7
⇒ 7.4 = 0.4 + 7
⇒ 7.4 = 7.4
⇒ Equation matched √
⇒ (2, 7.4) ⇒ y = 1/5x + 7

Thomas found a box that had a volume of 150 in3. He measured the height of the box to be 2 inches and the length was 10 inches more than the width. What is the width of the box?
Answers
The width of the rectangular box with volume of 150 cubic inches is: 5 inches.
What is the Volume of a Box?Volume of a box = (length)(width)(height).
Given the following:
Volume of the box = 150 in.³Height = 2 in.Width = w in.Length = w + 10 in.150 = (w + 10)(w)(2)
2w² + 20w - 150 = 0
Factorize
(w - 5)(w + 15) = 0
w = 5, w = -15
The width cannot be negative, therefore, the width of the box is: 5 inches.

y is directly proportional to the square root of x, y is 75 and x is 100. find a formula linking x and y
Answers
Answer:
y = 7.5[tex]\sqrt{x}[/tex]
Step-by-step explanation:
given y is directly proportional to [tex]\sqrt{x}[/tex] then the equation relating them is
y = k[tex]\sqrt{x}[/tex] ← k is the constant of proportion
to find k use the condition y = 75 , x = 100 , then
75 = k[tex]\sqrt{100}[/tex] = 10k ( divide both sides by 10 )
7.5 = k
y = 7.5[tex]\sqrt{x}[/tex] ← equation of proportion

Step-by-step explanation:
Sum of all angles of triangle = 180

∠Z = 180 - 156

The catalog is advertising a stack of these cups that is 95 cm tall. Lori says, “That must be a misprint because a stack of that height is not possible.”
Do you agree or disagree with Lori? Explain your reasoning.
Answers
Answer:
in particular, the relationship between height of stack and number of cups yields a non-whole number of cups, corresponding to a height of 95 cm. In this context, that is not possible because we do not allow for parts of cups.
Step-by-step explanation:
It is possible for a stack of cups to be 95 cm tall depends on the size and shape of the cups and how they are stacked.
What is Area of Rectangle?The area of Rectangle is length times of width.
Assuming the cups are all the same size and shape, the height of the stack would depend on the number of cups in the stack.
if each cup is 5 cm tall, a stack of 19 cups would be 95 cm tall (19 x 5 = 95).
If the cups are irregularly shaped or have varying sizes, it may be more difficult to stack them in a way that reaches 95 cm in height.
It is possible for a stack of cups to be 95 cm tall depends on the size and shape of the cups and how they are stacked.
It is possible for some stacks of cups to reach this height, but not necessarily all stacks of cups.
Hence, it is possible for a stack of cups to be 95 cm tall depends on the size and shape of the cups and how they are stacked.

Part D: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part B and Part C to draw the graph. (4 points)
Answers
A) factor f(x) are 3/5 and -1.
B) x-intercepts of the graph of f(x) are (3/5, 0) and (-1, 0).
C) The end behavior is explained by vertex of the graph which is (-0.2, -3.2)
D) The graph is symmetrical about x = -0.2. shown below
What is factorization?Factorizing is a way of writing an expression as a product of its factors using brackets.
Given function is : 5x² + 2x − 3
A)5x² + 2x − 3
= 5x² + 5x-3x − 3
= 5x(x+1)-3(x+1)
=(5x-3)(x+1)
So, factors will be 3/5 and -1.
B) f(x)= 5x² + 2x − 3
The x-intercepts are when f(x) = 0.
So, x-intercepts are (3/5, 0) and (-1, 0).
C) The x-coordinate of the vertex is the midpoint of the zeros.
midpoint= (3/5-1)/2
=-0.2
To find the y-coordinate of the vertex, substitute the found value of x into the given equation:
f(-0.2)= 5(-0.2)² + 2(-0.2) − 3
=-3.2
So, the end behavior is explained by vertex of the graph which is (-0.2, -3.2)
D) By plotting the zeroes and the vertex of the f(x).
The axis of symmetry is the x value of the vertex.
Thus, the graph is symmetrical about x = -0.2.
