Step-by-step explanation:
Change g(n) to y
y = 2n - 2
2y - 2 = n
2y = n + 2
y = (n + 2)/2
g^-1(n) = 1/2n + 1
solution is B

Pentagon JKLMN is similar to pentagon VWXYZ. What is the measurement of angle X? Group of answer choices 60o 120o 150o 30o
Answers
===========================================================
Explanation:
Based on the diagram, angles L and X are the top most angles. They correspond to have angle L = angle X = 60 degrees
Though you shouldn't rely solely on a diagram because the figures may be oriented in a strange way. A better way is to look at the letter sequences of JKLMN and VWXYZ
Notice how L and X are the third letters of JKLMN and VWXYZ respectively. This means the letters pair up and are congruent angles (since the polygons are similar). So this is a non-visual way to see how angle L = angle X = 60.

What is the distance, to the nearest whole number, from K (5, 6) to P (1, 1)?
Answers
Answer:
The answer is 6 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
K (5, 6) P (1, 1)
The distance from K to P is
[tex] |KP| = \sqrt{ ({5 - 1})^{2} + ({6 - 1})^{2} } \\ = \sqrt{ {4}^{2} + {5}^{2} } \\ = \sqrt{16 + 25} \\ = \sqrt{41} \\ = 6.403124[/tex]
We have the final answer as
6 units to the nearest whole numberHope this helps you
Setting 7/3 equal to which ratio would result in a valid proportion?
9/49
18/42
42/18
49/9
Answers
To determine which ratio would result in a valid proportion when set equal to StartFraction 7 over 3 EndFraction, we need to find the ratio that is equivalent to StartFraction 7 over 3 EndFraction.
To do this, we can cross-multiply. When we cross-multiply StartFraction 7 over 3 EndFraction and another ratio, the product of the numerator of StartFraction 7 over 3 EndFraction and the denominator of the other ratio should be equal to the product of the denominator of StartFraction 7 over 3 EndFraction and the numerator of the other ratio.
Let's check each option:
1. StartFraction 9 over 49 EndFraction:
7 x 49 = 343
3 x 9 = 27
These values are not equal, so it is not a valid proportion.
2. StartFraction 18 over 42 EndFraction:
7 x 42 = 294
3 x 18 = 54
These values are not equal, so it is not a valid proportion.
3. StartFraction 42 over 18 EndFraction:
7 x 18 = 126
3 x 42 = 126
These values are equal, so it is a valid proportion.
4. StartFraction 49 over 9 EndFraction:
7 x 9 = 63
3 x 49 = 147
These values are not equal, so it is not a valid proportion.
Therefore, the ratio that results in a valid proportion when set equal to StartFraction 7 over 3 EndFraction is StartFraction 42 over 18 EndFraction.

Oscar owns his own towing and auto repair service. He charges $45 for towing and $20 per hour, h, for labor. There is an additional charge for parts, p. Oscar uses this formula to determine the total cost, C, for towing and repairing a car. C = 45 + 20h + p What is the total cost, C, to tow and repair a car that requires four hours of labor and $109 worth of parts?
Answers
Answer:
24,28-11 that the answer
Step-by-step explanation:
Total cost C =$229 to tow and repair a car that requires 4hours of labor and $109 worth of parts.
What is total cost?"Total cost is defined as the sum of all the expenses which is required to produce a product."
According to the question,
C=total cost,
h= hour of labor
p = additional charges for parts
Total cost given as
C= 45 +20h + p
h = 4hour
p = $109
Substitute the value in the total cost we get,
C = 45+20(4) +109
=$229
Hence, total cost C =$229 to tow and repair a car that requires 4hours of labor and $109 worth of parts.

Explanation:
Triangle ABC is isosceles because AC = BC.
The angles opposite these congruent sides are angle ABC and angle BAC. These are the base angles.
For any isosceles triangle, the base angles are congruent.
Angle BAC = 69 degrees is given. So angle ABC = 69 as well.
-------------------
The missing angle must add to the two other angles so that all three angles in a triangle add to 180
(angle ABC) + (angle BAC) + (angle BCA) = 180
69 + 69 + (angle BCA) = 180
138 + (angle BCA) = 180
angle BCA = 180-138
angle BCA = 42
-------------------
Angle DCE is congruent to angle BCA because they are vertical angles.
Triangle DCE is a right triangle. The missing angle is 90-(angle BCA) = 90-42 = 48
