Answer:
y = 3x + 1
Step-by-step explanation:
This new line is parallel to y = 3x - 5 and thus has the same slope (3).
Adapting the point-slope formula y = mx + b to this situation, we use m = 3 and substitute 0 for x and 1 for y:
1 = 3(0) + b
Therefore, b = 1, and the desired equation is
y = 3x + 1
A group of students must collect at least $160 to organize a science fair. They have already collected $20. Which graph best represents the possible amounts of money the students still need to collect? (1 point) Number line graph with closed circle on 160 and shading to the right. Number line graph with closed circle on 140 and shading to the right. Number line graph with closed circle on 20 and shading to the right Number line graph with closed circle on 180 and shading to the right.
Answer:
Number line graph with closed circle on 20 and shading to the right or c
Step-by-step explanation:
This is the best answer because you start of at 20 dollars and need to continue collecting money till you have 160 dollars.
Answer:
The 3rd one
Step-by-step explanation:
You have already collected $20. You need at least $160, but having even more money would be great. You need $160, but any number to the right of 160 would be even better as your goal.

A rectangular prism has a length of 9 in., a width of 4 in., and a height of 1 1/2in. The prism is filled with cubes that have edge lengths of 1/2 in. How many cubes are needed to fill the rectangular prism?
Hey there! :)
Answer:
432 cubes.
Step-by-step explanation:
Volume of rectangular prism: V = l × w × h
V = 9 × 4 × 1.5
V = 54 in³
Volume of cubes: V = s³
V = 1/2³
V = 1/8 in³
Set up an equation to solve for the # of cubes needed (x):
54 = 1/8x
Divide both sides by 1/8:
54 × 8/1 = x
x = 432 cubes.

Write each ratio in its simplest form.
A) 9 feet: 4 yards
B) 5 gallons : 8 quarts
C) 800 centimeters: 2 meters
Answer:
A. 4 yards = 12 ft
9 ft : 12 ft = 3:4
B. 5 gallons = 20 quarts
20 quarts : 8 quarts = 5:2
C. 2 meters = 200 cm
800 cm : 200 cm = 4:1
Answers:
A) 3:4
B) 5:2
C) 4:1
Step-by-step explanation:
Convert 4 yards to feet.
1 yard = 3 feet
4 yards = 12 feet
9 feet : 12 feet
Simplify the ratio.
9/3 : 12/3
3 feet : 4 feet
3 : 4
Convert 8 quarts to gallons.
1 quart = 0.25 gallons
8 quarts = 2 gallons
5 gallons : 2 gallons
5 : 2
Convert 2 meters into centimeters.
1 meter = 100 centimeters
2 meters = 200 centimeters
800 centimeters : 200 centimeters
Simplify the ratio.

O A. Yes, because every x-value corresponds to exactly one y-value.
O B. Yes, because the y-values are positive numbers.
O C. No, because none of the yvalues are the same.
O D. No, because each x-value is different,
The answer is A; every x-value must correspond to ONE y-value only. y-values can correspond with as many x-values as they want, but if you see an x-value corresponding with more than one y-value, that's not a function.
The table represent the function because every x-value corresponds to exactly one y-value.
What is function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Find the equation of the exponential function represented by the table below:
HELLPPP
Answer:
y = 4 [tex](\frac{1}{2}) ^{x}[/tex]
Step-by-step explanation:
For an exponential function in the form
y = a [tex]b^{x}[/tex]
Use ordered pairs from the table to find values of a and b
Using (0, 4 ), then
4 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), thus
a = 4, so
y = 4 [tex]b^{x}[/tex]
Using (1, 2 ) , then
2 = 4 [tex]b^{1}[/tex] = 4b ( divide both sides by 4 )
b = [tex]\frac{1}{2}[/tex]
Thus exponential function is
y = 4 [tex](\frac{1}{2}) ^{x}[/tex]
Answer:
y = 4 (\frac{1}{2}) ^{x}

a number cube numbered 1-6 is rolled 30 times and lands on an even number 18 times. How does this frequency compare to the expected frequency based on the probability of the number cube landing on an even number?
Answer:
The frequency is 3 more than expected
Step-by-step explanation:
There are 3 favourable outcomes: {2, 4, 6}
There are 6 possible outcomes: {1, 2, 3, 4, 5, 6}
probability of the number cube landing on an even number = favourable outcomes / possible outcomes = 3/6 = 1/2
If the cube is rolled 30 times, it is expected that in 1/2*30 = 15 times landed on an even number. The frequency: 18 is 3 more than expected

Answer:
a) 2.8 liters
b) 12400 cm³
Step-by-step explanation:
1 cm³ = 1 mL
1000 mL = 1 L
a)
2800 cm³ × (1 mL)/(1 cm³) × (1 L)/(1000 mL) = 2.8 L
b)
12.4 L × (1000 mL)/(1 L) × (1 cm³)/(1 mL) = 12400 cm³
this is a sketch of the curve with equation y=f(x) the vertex of the curve is at (2,-3)
Answer:
see explanation
Step-by-step explanation:
(a)
Given f(x) then f(x) + c represents a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
f(x) + 5 represents a shift up of 5 units, thus
(2, - 3 ) → (2, - 3 + 5 ) → (2, 2 )
(b)
Given f(x) then - f(x) represents a reflection of f(x) in the x- axis
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(2, - 3 ) → (2, 3 )
The vertex of the given curve is the minimum point on the curve.
The vertex of f(x) + 5 is (2,2)The vertex of -f(x) is (2,3)The vertex is given as:
[tex]\mathbf{(x,y) = (2,-3)}[/tex]
(a) The vertex of f(x) + 5
The rule of the given transformation is:
[tex]\mathbf{(x,y) \to (x,y + 5)}[/tex]
So, we have:
[tex]\mathbf{(x,y) \to (2,-3 + 5)}[/tex]
[tex]\mathbf{(x,y) \to (2,2)}[/tex]
Hence, the vertex of f(x) + 5 is (2,2)
(b) The vertex of -f(x)
The rule of the given transformation is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, we have:
[tex]\mathbf{(x,y) \to (2,-(-3))}[/tex]
[tex]\mathbf{(x,y) \to (2,3)}[/tex]
Hence, the vertex of -f(x) is (2,3)
