Answer:
3.-5 is correct
Step-by-step explanation:
We are given,
The table which represents a function.
Now, 'A function is a relation in which every element of the domain has a unique image'.
So, from the table, we see that,
-5 has the image 15.
So, it cannot have another image.
Thus, the number which cannot be used to complete the table is -5.
Hence, option C is correct.
Delta math question —-
Answer:
21
Step-by-step explanation:
I think its 21, because the BD line divides the big triangle into 2 ones and they are equilateral triangle, sorry if I'm wrong
Answer:
BD = 21
Step-by-step explanation:
The sector divided AC into two equal pieces and since this is a right triangle the height of the triangle BD is equal to half of the base
(21+21) / 2 = x
42 / 2 = x
21 = x
Fransisco and kazuko guess the number of marbles in a jar. Fransisco guesses 50 marbles and kazuko guesses 60. The actual number of marbles is 55. Kazuko says there is less error in her guess because 50/50=10% and 5/60= 8.3%. Explain why kazuko is incorrect
Answer:
The difference in both the guessed values is 5 unit
Step-by-step explanation:
The less error computation is done by dividing the difference between the guessed value and the actual value.
Here in this case
Error in case of Fransisco = 55-50 = 5
Error in case of Kazuko = 60 -55 = 5
Hence, both have guessed incorrect value and their incorrect values is either 5 units less or 5 units higher than the actual value.
43/19 as a decimal rounded nearest hundredth
Answer:
2.26
Step-by-step explanation:
To round our answer to nearest hundredth, we will round our answer to 2 digits after decimal. We can see that thousandth value is less than 5 that is 3, so will keep last digit 6 as: Therefore, the decimal value of our given fraction is approximately 2.26 to the nearest hundredth.

Given that (3, 2, -6) and (-2,5, 1) are solutions of two equations in a system of three linear equations, which of the following is true about the system?
Answer :
The system can be inconsistent or consistent and independent or consistent and dependent.
Step-by-step explanation :
Consistent system: When the system of equation have atleast one solution then the system is consistent.
Inconsistent system: When the system of equation have no solution then the system is called inconsistent.
Dependent system: When the consistent system have infinite number of solutions then the system is called dependent.
Independent system: When the consistent system has exact one solution then the system is called independent system.
We are given two solutions of two equations are (3,2,-6) and (-2,5,1).
But the system of equations have three equations.
Then, the system of equations may have no solution or may have altleast one solution.
If given system of equations have no solutions then the system is inconsistent.
If the given system of equations have two or more than two solutions then the system is consistent and dependent.
If the given system of equations has exactly one solution then the system is consistent and independent.
The system can be inconsistent or consistent independent or consistent independent.

Cole bought 10 gallons of gas at the gas station with the lowest price. He paid with two $20 bills. Write and solve an equation to find his change.
Answer:
$4.3
Step-by-step explanation:
Cole bought 10 gallons of gas at the gas station with the lowest price.(the lowest price is $3.57 each gallon.) He paid with two $20 bills. Write and solve an equation to find his change.
two $20 bills = 2 * $20
= $40
Gallons of gas = 10
Lowest price of each gallon = $3.57
Cost of 10 gallons of gas = 10 * $3.57
= $35.7
Let his change = x
His change = Amount paid with - cost of gas
x = $40 - $35.7
x = $4.3
His change = $4.3

Anyone please me on this!!
Answer:
27 degrees
Step-by-step explanation:
So looking at this rhombus, we can make out 4 seperate traingles.
How many degrees are in a traingle? 180.
Looking at the traingle with z angle in it, we can see that it is a right traingle.
Now, lets subtract that 90 degrees from the 180.
This leaves us with the 63 degrees and x that make up the 90 degrees that are left.
Now all we have to do is subtract the 63 degrees from the 90 total degrees that we have left, and we will find out what z is equal to.
90 minus 63 is 27, so the angle of z is:
27 degrees
I hope this helps!
Note that I assumed these are right traingles, however I dont see how you can solve this without these being right trianlges, since you cannot use sin, cos, or tan to find this value without another angle or side length.

PLZ HELP ASAP!! Given g(x)=f(x)+k, enter the value for k that transforms the function f into g?
What does k=
Answer:
k = -2
Step-by-step explanation:
firstly, let us examine the kind of transformation that we have
We have a transformation from (3,2) to (3,0) and (-3,0) to (-3,-2)
So, we are actually subtracting 2 from the values of f(x) to get the values of g(x)
This shows a vertical translation to the tune of 2 units in the downward direction
So, the correct answer here is that -2 is being subtracted from f(x) to give g(x)
Accordingly, the value of k in the question is -2

Graph f(x) = 6x^2-11+3 and
find the zeroes
Answer:
x = ±1.155
Step-by-step explanation:
We need to graph the given function [tex]f(x) = 6x^2-11+3[/tex] and find its zeroes.
The attached figure shows the graph of the given function.
To find zeroes,
Put f(x) = 0
So,
[tex]6x^2-11+3=0\\\\x=\pm 1.155[/tex]
Hence, this is the required solution.

Lacey graphed a system of linear equations. What is the solution to the system of
equations?
45678910
(-1,3)
(0,2)
(-4,2)
Answer:
(-1, 3)
Step-by-step explanation:
In order for a point to be a solution to a system of equations, the lines have to intersect at that point in the graph. We can see that the two lines at the graph intersect at (-1,3), so that must be the solution.

Help! Best answer gets brainliest
Answer:
7.9
Step-by-step explanation:
the first thing to do is find the second projection.
16-7 = 9
than we can use a proportion to find BD
7 : BD = BD : 9
BD = √9 x 7 = √63 = 7.9
we have to use the square root because in the proportion BD Is repeated two times. If we don’t use it, we find BD^2
