Answer:
The number that could not be a value of y if y = 4x² - 6 is -12.
Step-by-step explanation:
What is the value of y for a function of f(x)?The value of y for which a function f(x) = y = 4x² - 6 can be determined by knowing the smallest value of y for which x is equal to zero.
So, from the equation y = 4x² - 6, we will replace the value of x with zero to determine the smallest value of y.
y = 4(0) - 6
y = 0 - 6
y = -6
Thus, any number smaller than -6 could not be a value of y for the equation y = 4x² - 6.
Therefore, we can conclude that the number that could not be a value of y if y = 4x² - 6 is -12.

The new translated function will be more towards the origin , as the value of length is decreased , Option C is the right answer.
What is a Function ?A function is a mathematical statement used to relate a dependent and an independent variable.
It is given that
Area of a Rectangle is 10 sq. unit
Width of the Rectangle is x unit
Length is given by
l(x) = 10 / x
When the length of the Rectangle is increased by 1 ,
The new function will be
l(x) = 10 /(x+1)
The new translated function will be more towards the origin , as the value of length is decreased ,
This is represented by Graph 3 ,
This can be proved by keeping the value of x
let x = 2
y = 10 /3 = 3.333
This is only in the graph 3 , Therefore Option C is the right answer.

Thé nth term rule for a sequence is 4n + 7 what is the 3rd term of this sequence?
Answer:
a₃ = 19
Step-by-step explanation:
to find the third term substitute n = 3 into the nth term rule
a₃ = 4(3) + 7 = 12 + 7 = 19
Answer:
a₃ = 19
Step-by-step explanation:
the relationship between any two terms of an arithmetic sequence (in our case the relationship between the 3rd term and nth term) gives us this equality :
[tex]a_n - a_3 = 4(n-3)[/tex]
Then
4n + 7 - a₃ = 4n - 12
Then
7 - a₃ = - 12
Then
7 + 12 = a₃
Then
a₃ = 19

The jones family and the Connor family both bought the same boxed package of sugar cubes at the store, in which the cubes were arranged in 5 layers. After drinking of 61 cups of tea, the Joneses found that they were out of sugar. The Connors' sugar box was enough to last them thought 88 cups of tea. Both families put either 2 or 3 pieces of sugar per cup. How many sugar cubes were in the box
The number of sugar cubes in the box is 180
How to determine the number of sugar cubes?The given parameters are:
Layers = 5Pieces = 2 or 3Cups of tea = 61 and 88Multiply 61 and 88 by 2 and 3
61 * 2 = 122
61 * 3 = 183
88 * 2 = 176
88 * 3 = 264
The number of sugar cubes cannot be 122 and 264, because they are out of the range
So, we have:
183 and 176
There are 5 layers.
This means that the number of sugar cubes is divisible by 5.
The only number between 176 and 183 that is divisible by 5 is 180
Hence, the number of sugar cubes is 180

Between what months will the temperature be below 0°C?
The months with temperature below 0° is August and October.
GIven,
T(m) = 4 sin (π/6 m)₊2
In the above equation, T(m) is the average temperature in a month in degrees Fahrenheit, and m is the month of the year.
T(8) = 4 sin (8π/6 m)₊2
= 4 sin (4π/3 )₊2
= 4 sin (π₊π/3 )₊2
= ₋4 sin π/3 ₊2
= ₋4×√3/2 ₊2
= ₋2√3 ₊ 2 <0
The function for the average monthly temperature, in m months from january is given by
T(0) = 4 sin(10π/6) ₊ 2
= 4 sin(5π/3) ₊ 2
= 4 sin(2π ₋ π/3) ₊ 2

Which linear function has the same y-intercept as the one that is represented by the graph? On a coordinate plane, a line goes through points (negative 4, 0) and (0, 3). a y = 2 x minus 4 b y = 2 x minus 3 c y = 2 x + 3 d y = 2 x + 4
The line which is having same y intercept as the line which passes through points (-4,0) and (0,3) is y=2x+3.
Given Points through which the line passes through are (-4,0) and (0,3)
We have to find the equation whose y intercept is equal to the y intercept of the line whose points given above.
First of all we have to find the y intercept of the line which passes through (-4,0) and (0,3). Equation of line is :
y-y1=(y2-y1)/(x2-x1)*(x-x1)
y-0=(3-0)/(0+4) *(x+4)
y=3/4(x+4)
y -intercept exists where x=0
put x=0
y=3
So the options are:
y=2x-4y=2x-3y=2x+3y=2x+4By putting the value of x in all options we will find
y=-4
y=-3
y=3
y=4
So the third option is correct.

The exponential function is [tex]f(x) = 18(12)^{-x-4} + 2[/tex]
How to determine the equation?An exponential function is represented as:
y = b^x
Where b represents the base.
The base is given as:
b = 12
So, we have:
y = (12)^x
It is vertically compressed by a factor of 1/8.
So, we have:
y = 18(12)^x
When reflected across the y-axis, we have:
[tex]y = 18(12)^{-x}[/tex]
The horizontal asymptote is y = 2.
So, we have:
[tex]y = 18(12)^{-x} + 2[/tex]
It passes through the point (-3, 4).
So, we shift the function to the right by 4 units
[tex]y = 18(12)^{-x-4} + 2[/tex]
Express as a function
[tex]f(x) = 18(12)^{-x-4} + 2[/tex]
Hence, the exponential function is [tex]f(x) = 18(12)^{-x-4} + 2[/tex]
