Answer:
y= 16, 64, 256, 1024
y/x= 16/2, 64/3, 256/4, 1024/5,
Step-by-step explanation:
This is just like any other equation, except instead of x being a number, it is an exponent. For example, when x equals 2, y equals 16 because y always equals four to the power of x. This applies to all of the parts in your table. when x equals 3, y equals 4^3 (4 times 4 times 4) which is 64, and when x equals 4, y equals 4^4 (4 times 4 times 4 times 4), which is 256.
For the y over x part that is just the value y, divided by the value x. For the first line on the table x equals 2, and we know y equals 16 (4^2 is 4 times 4, which is 16) so 16 divided by 2 is 8. That is the answer.
Hope this helps :)

Which linear inequality is represented by the graph? y > 2x 3 y < 2x 3 y > −2x 3 y < −2x 3
The equation represents the inequality will be y < −2x + 3.Option d is correct.
What is linear inequality?Linear inequalities involve at least one linear algebraic expression. A polynomial of degree 1 is compared to another algebraic expression of degree less than or equal to 1.
Different types of linear inequalities can be represented in a variety of ways.
The linear equation with slope m and intercept y is given as;
y=mx+c
The inequalities are as follows;
(a). y > 2x +3
(b). y < 2x+ 3
(c). y > −2x+ 3
(d). y < −2x+ 3
Because the line meets the y-axis,(0,3)the y-intercept is 3.
The points are (0,3)and(1,1)
The line's slope may be calculated as follows.
[tex]\rm m= \frac{1-3}{1-0} \\\\ \rm m= -2[/tex]
On putting the given origin value;
[tex]y < -2x+3 \\\\0 < -2(0)+3\\\\0 < 3[/tex]
From all the data obtained we get the equation given in option d is correct.
Hence the equation that represents the inequality will be y < −2x + 3.Option d is correct.

Limits do not give the y-value AT the given x; rather they give what y-values the function is __________ AROUND the given x
Using limits, it is found that the correct statement is:
they give what y-values the function is AROUND the given x.
What is a limit?The limit of a function f(x) as a value of x = a is approached is given by:
[tex]y = \lim_{x \rightarrow a} f(x)[/tex]
The limit can be calculated at a point in which a function is not continuous, for example, in which we consider the lateral limits, which is not the exact value at x = a, but the value of the function as x approaches a by the left and by the right, hence the correct statement is:
they give what y-values the function is AROUND the given x.

Insert three arithmetic means between -16 and 4.
Answer:
Three arithmetic means between -16 and 4 are : 20 , 10 and [tex]\frac{20}{3}[/tex]
Step-by-step explanation:
we have to find out three arithmetic means between -16 and 4
-16 , ____ , ____ , ____ 4
so , lets take the mean like this ,
-16 , -16+d , -16+2d ,-16+3d , 4
First mean -: -16 +d = 4
d= 4+16
d = 20
second mean -: -16 +2d = 4
2d= 4+16 = 20
d= [tex]\frac{20}{2}[/tex]
d= 10
third mean -: -16+3d = 4
3d = 20
d=[tex]\frac{20}{3}[/tex]
Therefore , all the three arithmetic means between -16 ad 4 are 10 , 20 and [tex]\frac{20}{3}[/tex] .

Find the domain and range of the function represented by the graph
Step-by-step explanation:
Work and answer shown above
The Domain is -4 ≤ x ≤ 2
Range = 2 ≤ y ≤ 6
We have given a graph of a function. We have to find the domain and the range of the function
The domain refers to the set of all valid input values for a function. It represents the values for which the function is defined or meaningful. In other words, it is the set of x-values that can be plugged into the function to obtain a corresponding y-value.
The range, on the other hand, refers to the set of all possible output values or y-values that result from evaluating the function with the input values from the domain. It represents the set of all values that the function can attain.
As we can see from the graph
value of x is greater than and equal -4 and less than and equals 2
Domain = -4 ≤ x ≤ 2
Value of y is grater than and equal to 2 and less than and equal to 6
Range = 2 ≤ y ≤ 6

Answer:
c
Step-by-step explanation:
To find the maximum point, differentiate:
D' = -8p +160
Set to zero and solve for p:
D' = 0
⇒ -8p +160 = 0
⇒ 8p = 160
⇒ p = 20
Input p = 20 into the original equation to find D:
D = -4(20)² + 160(20) -310 = 1290
Therefore, the price is $20 and the maximum number of drills is 1,290

The formula for distance traveled d is d=rt, where r is the average speed of the object and t is time traveled. If an object travels 30 meters in 20 seconds, what is its speed
Answer:
Step-by-step explanation:
Distance formula:
d = rt
where d = distance, r = average speed and t = time travelled.
They told us that an object travels 30 meters in 20 seconds.
So we can say d = 30 and t = 20
If you put these values back into the distance formula you get:
d = rt
30 = r times 20
30 = 20 r
So now we want to find what "r" (average speed) is.
Divide both sides by 20.
20 r = 30
r = [tex]\frac{30}{20}[/tex] = 1.5 meters per second.

Answer:
Step-by-step explanation:
3x^2 + 8x - 16 - SOMETHING = x^2 - 4
Re-arranging left and right:
SOMETHING = 3x^2 + 8x - 16 - x^2 + 4
= (3x^2 - x^2) + 8x - 16 + 4
= 2x^2 + 8x - 12
Answer:
Original expression: [tex]3x^2+8x-16[/tex]
Let [tex]a[/tex] be the quantity Amir subtracted from the original expression.
Expression after subtraction: [tex]x^2-4[/tex]
[tex]\implies (3x^2+8x-16)-a=x^2-4[/tex]
Solve for [tex]a[/tex]:
[tex]\implies 3x^2+8x-16-a=x^2-4[/tex]
Add 4 to both sides:
[tex]\implies 3x^2+8x-12-a=x^2[/tex]
Subtract [tex]x^2[/tex] from both sides:
[tex]\implies 2x^2+8x-12-a=0[/tex]
Add [tex]a[/tex] to both sides:
[tex]\implies 2x^2+8x-12=a[/tex]
Therefore, Amir subtracted [tex]2x^2+8x-12[/tex] from the original expression.
