Answer: A function is so F(X) = Y where for every X exist only one Y, in this case you can see that F(3) = 4 and F(3) = 3, so the independent variable x = 3, has two solutions y.
So the solution is A, because a function cannot have two different y values for one x value.

Your football team gained four yards on the first down into yards on the second down during its last possession which number is the additive inverse of yards gained
A-2
B -6
C 4
d 6
Answers
Answer:
B. -6
Step-by-step explanation:
There is a mistake in the question. It would have to say:
Your football team gained four yards on first down and two yards on second down during its last possession
So, your team gained 4 + 2 = 6 yards.
Calling x, the additive inverse of 6, the following equation must be satisfied:
6 + x = 0
x = 0 - 6
x = -6
1: -(5x + 7) + 1 = -5x -5
2: 4x - 7 + 2x = 2(3x - 3) - 1
3: -4x - 2 = -2(1 - 4x)
Answers
-5x -6 = -5x + 5
-5x - 6 + 6 = -5x +5 + 6
-5x = -5x +11
-5x + 5x = -5x + 5x + 11
0 does not equal 11 so there is not solution to number 1 or you can write 0 does not equal 11.
2. 4x - 7 + 2x = 2(3x-3) -1
6x - 7 = 6x -6 -1
6x -7 + 7 = 6x -7 + 7
(6x = 6x) / 6
x = x; this is an identity which means x can be any real number and the value will still be equal.
3. -4x -2 = -2(1 - 4x)
-4x - 2 = -2 + 8x
-4x - 2 + 2 = -2 + 2 + 8x
(-4x = 8x) / -4
x = -2x ; there is no real answer

-1-10m=-81 We combine our like-terms.
+1 +1
-10m=-80 We add1 to both sides (to isolate the variable).
/-10 /-10
m=8 We divide by -10 on both sides (to isolate the variable).
With the math above, we know that the solution to the first equation is that m=8. Now let's begin the second.
-5(6v-7)-7=238 We start with our equation.
-30v+35-7=238 We distribute our "-5."
-30v+28=238 We combine our like-terms.
-28 -28
-30v=210 We subtract 28 from both sides (to isolate the variable).
/-30 /-30
v=-7 We divide by -30 on both sides (to isolate the variable).7
Using the math above, we can see that the solution to the second equation is v=-7.

negative one sixth of a number is less than -9
Answers
explanation:
step 1: set up the problem: -1/6n<-9
step 2: multiply both sides by the reciprocal of -1/6, -6, to isolate n
step 3: -9 times -6 is positive 54
so the number is 54
The number will be greater than 54 such that a negative one-sixth of a number is less than -9.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
A mathematical phrase in which the sides are not equal is referred to as being unequal.
Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Let's suppose that number is x
Then,
negative one-sixth of x
-(1/6)x is less than -9
-(1/6)x < -9
-x < -54
Multiplying by - will change the sign of inequality
So,
x > 54
Hence "The number will be greater than 54 such that a negative one-sixth of a number is less than -9".

the answer would be b. C=(2,0), A=(0,1), T=(1,4)
all x's move 2 to the right and no change in y
Solution: If a shape is being translated neither it's shape nor size changes.When we translate a shape we just move a shape or geometrical figure by certain distance either horizontally or vertically or both horizontally and vertically.
Coordinates of Triangle CAT is →C(0,0), and A(-2,1), and T(-1,4).
In option (a) vertices C has not been translated , but A and T are translated.Which is Untrue because we have to move all the vertices by same value. But x and y can have different value.
In option (b) all the coordinates C,A,and T is being translated along→ x by 2 units , horizontally right, but not translated in vertical direction.
C(0,0)⇒C(0+2,0+0)→C(2,0)
A(-2,1)⇒C(-2+2,1+0)→C(0,1)
T(-1,4)⇒C(-1+2,4+0)→C(1,4)
In option C, Coordinates of A and B are changed but not of C, So in this case translation can't happen.
In option D , C is being translated 2 units horizontally left , but amount of translation in A and T are different.
So , Option (b) is true.

Answers
m∠A =73.7°
m∠B = 16.3°
m∠C = 90°
Answer:
(C)
Step-by-step explanation:
It is given that a right triangle, ACB which is right angled at C has BC = 24 inches, and AB = 25 inches.
We know that m∠C=90°,
Using the trigonometry in ΔACB, we have
[tex]sinB=\frac{AC}{AB}[/tex]
Substituting the given values, we get
⇒[tex]sinB=\frac{24}{25}[/tex]
⇒[tex]B=sin^{-1}(0.96)[/tex]
⇒[tex]B=73.7^{\circ}[/tex]
Also, [tex]sinA=\frac{CB}{AB}[/tex]
Substituting the given values, we get
⇒[tex]sinA=\frac{7}{25}[/tex]
⇒[tex]A=sin^{-1}(0.28)[/tex]
⇒[tex]A=16.3^{\circ}[/tex]
Therefore, the measure of the angles in triangle ABC are m∠A ≈ 73.7°, m∠B ≈ 16.3°, m∠C ≈ 90°.
Thus, option C is correct.

A group of students is investigating whether copper is a better thermal conductor than steel. The students take a copper wire and a steel wire of the same length and diameter. They put equal lengths of wax on one end of each wire and dip the other end into a beaker of hot water. The length of wax left on the wires after 10 minutes is shown.
Experimental Observations
Copper Steel
Original length of wax: 3 cm 3 cm
Length of wax after 10 minutes: 0.7 cm 1.8 cm
What was the dependent variable in this experiment?
Type of wire used
Original length of wire
Original length of wax
Thermal conductivity of wire
Answers
The correct dependent variable in this experiment is the Length of wax after 10 minutes.
In the context of an experiment, the dependent variable is the variable that is being measured or tested in the experiment. It is the outcome that the experimenters are interested in observing to determine the effect of the independent variable.
In this case, the students are investigating the thermal conductivity of copper and steel wires by observing how much wax melts over a fixed period of time when the wires are heated. The independent variable is the type of wire used (copper or steel), as this is what the students are changing to see its effect on the dependent variable.
The dependent variable is the length of wax remaining after 10 minutes because this measurement is expected to change based on the thermal conductivity of the wire. The better the thermal conductor, the more heat will be transferred along the wire, and the more wax will melt. Since the students are measuring how much wax has melted (by subtracting the length of wax after 10 minutes from the original length), this is the dependent variable.
The original length of wire and the original length of wax are control variables; they are kept constant to ensure that any differences in the dependent variable are due to the independent variable (the type of wire) and not due to other factors. The thermal conductivity of the wire is a property being indirectly measured through the observation of the dependent variable. It is not directly measured and thus is not the dependent variable.

Answers
Final answer:
After solving the original equation 2/3(6x+12)=-24, we find x = -8. Comparing this solution with the provided equations, the ones that have the same value for x are 9x+18=-24, 18x+36/2=-24, and x=-8.
Explanation:
To find which equations have the same value for x as 2/3(6x+12)=-24, we must first solve the original equation to find the value of x it yields:
2/3(6x+12) = -24
Multiply both sides by 3/2 to eliminate the fraction:
6x + 12 = -24 * (3/2)
6x + 12 = -36
Subtract 12 from both sides:
6x = -48
Divide by 6:
x = -8
Now we will compare this solution with the other equations:
4x+8=24 -> Does not match.9x+18=-24 -> When solving for x, we get x=-8, which matches.4x+12=-24 -> Does not match.18x+36/2=-24 -> Simplify to get 9x+18=-24, x = -8, matches.4x=-36 -> Does not match.4x=-32 -> Does not match.x=-9 -> Does not match.x=-8 -> Directly given the solution, which matches.Therefore, the equations that have the same value of x as the original equation are 9x+18=-24, 18x+36/2=-24, and x=-8.

Answers
The measure of an interior angle of the regular polygon is 156 degrees and the polygon has 15 sides.
Explanation:In a regular polygon, the measure of an exterior angle is equal to 360 degrees divided by the number of sides of the polygon. In this case, the measure of the exterior angle is given as 24 degrees. So we can set up the equation:
24 = 360 / n
Where n is the number of sides. Cross multiplying, we get:
n = 360 / 24 = 15
So the polygon has 15 sides. To find the measure of an interior angle, we can use the formula:
Interior Angle = 180 - Exterior Angle
Interior Angle = 180 - 24 = 156 degrees

Find the center and radius for the circle defined by the equation x^2 + y^2 + 5x -y + 2
Answers
Center is (-2.5, 0.5)
Radius is 2.12 units
Note: the value of the radius is approximate and rounded to 2 decimal places
If you need the exact value in terms of a square root, then the exact radius is sqrt(4.5) units long where 'sqrt' stands for 'square root'
-----------------------------------
-----------------------------------
Work Shown:
We need to complete the square for the x and y terms
x^2 + y^2 + 5x - y + 2 = 0
(x^2 + 5x) + (y^2 - y) + 2 = 0
(x^2 + 5x + 6.25 - 6.25) + (y^2 - y) + 2 = 0 .... see note1 below
(x^2 + 5x + 6.25 - 6.25) + (y^2 - y + 0.25 - 0.25) + 2 = 0 .... see note2 below
(x^2 + 5x + 6.25) - 6.25 + (y^2 - y + 0.25) - 0.25 + 2 = 0
(x^2 + 5x + 6.25) + (y^2 - y + 0.25) + (-6.25 - 0.25 + 2) = 0
(x^2 + 5x + 6.25) + (y^2 - y + 0.25) - 4.5 = 0
(x + 2.5)^2 + (y - 0.5)^2 - 4.5 = 0
(x + 2.5)^2 + (y - 0.5)^2 = 4.5
So the center is (-2.5, 0.5) and the radius is roughly 2.12 units, which is the result of taking the square root of 4.5
sqrt(4.5) = 2.12132 approximately and that rounds further to 2.12
