Which equation is the inverse of y = 7x² - 10?
The inverse of y = 7x² - 10 is √(x+10)÷7
What does mathematics inverse mean?Inverse operations, such as addition and subtraction, multiplication and division, are pairs of mathematical operations where one operation reverses the effects of the other. The term "inverse" refers to the reciprocal of a number, i.e., x - 1 = 1 / x. One is the result when a number is multiplied by its reciprocal, or inverse.
based on the available facts;
y = 7x^2 - 10
Switch y and x.
x = 7y^2 - 10
Solve for y.
Add 10 to both sides.
x + 10 = 7y^2
Divide both sides by 7.
(x + 10)/7 = y^2
√ both sides.
√(x + 10)/7 = y
Replace y with f^-1(x)
f^-1(x) = √(x + 10)/7y = 7x^2 - 10
Switch y and x.
x = 7y^2 - 10
Solve for y.
Add 10 to both sides.
x + 10 = 7y^2
Divide both sides by 7.
(x + 10)/7 = y^2
√ both sides.
√(x + 10)/7 = y
Replace y with f^-1(x)
f^-1(x) = √(x + 10)/7

Answer:
x=3 and N is the mid-point.
Okay, so if N is the mid-point.
E D=15
E N=4 x -1
N D=4+ 2 x
6 x -3=15
Now get the 6 x by itself, so move the 3 over
So it would be: 6 x =18
So that would be 6 divided by 6 is x and then 18 divided by 6 equals 3
So, X equals 3

Step-by-step explanation:
A bag contains 3 blue chips, 7 red chips, 4 yellow chips, and 5 green chips. A chip is randomly drawn from the bag. Find probability.
P (not red)
If a chip is randomly drawn from the bag, the probability it is not a red one is P(not red) = 12/19.
Probability of an event A is the number of event A divided by all possible outcomes. Mathematically,
P(A) = n(A)/n(S)
where:
n(A) = number of event A
n(S) = number of all possible outcomes or sample space.
Suppose there 3 possible outcomes, A, B, and C, then:
n(S) = n(A) + n(B) + n(C)
1 = P(A) + P(B) + P(C)
The probability the outcome is not event A is equal to the probability of (B or C), or in other words,
However,
P(B or C) = P(B) + P(C)
It means,
P(not A) = 1 - P(A)
In the given problem:
Number of chips:
Blue = 3
Red = 7
Yellow = 4
Green = 5
Total chips = 3 + 7 + 4 + 5 = 19
If a chip is randomly drawn, the probability it will be a red one is:
P(red) = 7/19
Hence
P(not red) = 1 - 7/19 = 12/19

The graph of an absolute value function has a vertex of (3, 6) and crosses the x-axis at (-3,0) and (9,0). What is the equation of the absolute value function?
The equation of the absolute value function is y = -|x - 3| + 6
How to determine the equation of the absolute value function?The given parameters are
Vertex = (3, 6)
Crosses the x-axis at (-3,0) and (9,0)
An absolute value equation is represented as
y = a|x - h| + k
Where
Vertex = (h, k)
So, we have
y = a|x - 3| + 6
At (-3, 0), we have
0 = a|-3 - 3| + 6
This gives
0 = a|-6| + 6
So, we have
0 = 6a + 6
Solve for a
a = -1
Substitute a = -1 in y = a|x - 3| + 6
y = -|x - 3| + 6
Hence, the equation of the absolute value function is y = -|x - 3| + 6

Prove by C/D formula that cos A + cos 2A + cos 5A = cos 2A (1 + 2 cos 3A)
We have proved the trigonometric expression cos A + cos 2 A + cos 5 A = cos 2 A (1 + 2 cos 3 A) by using C/D formula.
We are given the expression:
cos A + cos 2 A + cos 5 A = cos 2 A (1 + 2 cos 3 A)
We need to prove the expression.
We know that:
Cos C + Cos D = 2 cos ( C + D / 2) cos ( C - D / 2)
Using this identity, we get that:
= cos 5 A + cos A + cos 2 A = cos 2 A (1 + 2 cos 3 A)
= 2 cos ( 5A + A / 2) cos ( 5A - A / 2) + cos 2 A = cos 2 A (1 + 2 cos 3 A)
= 2 cos 3 A cos 2 A + cos 2 A = cos 2 A (1 + 2 cos 3 A)
= cos 2 A ( 2 cos 3A + 1) = cos 2 A (1 + 2 cos 3 A)
= cos 2 A (1 + 2 cos 3 A) = cos 2 A (1 + 2 cos 3 A)
LHS = RHS
Hence proved.

9. a flat shape with 4 straight sides where: all sides have equal length, and every interior angle is a right angle
It is square-shaped as it is 4-straight sides with equal length, and every interior angle is right angle.
Why do you use the term "right angle"?A right angle is defined as an angle in geometry and trigonometry that is exactly 90 degrees, or pi /2 radians, or one-quarter turn. The adjacent angles are right angles if a ray is positioned so that its terminus is on a line and they are equal. An interior angle is a shape's internal angle. The closed shape with sides and vertices is a polygon. All of the inner angles of a regular polygon are equal to one another. For instance, a square has interior angles that are all exactly right angles, or 90 degrees. The right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection. The symbol is used to indicate a right angle.

Graph the line y = x on graph paper.
a. Draw a slope triangle.
b. Rotate your slope triangle 90° around the origin to get a new
slope triangle. What is the new slope?
c. Write an equation of a line perpendicular to y = x.
Answer: To graph y = x is simple, it is a line that intercepts at 0, and goes up by 1/1, or 1 (rate of change)
Step-by-step explanation:
1. For C, it's simple, it is y = -x, since the negative reciprocal slope is usually perpendicular to the original number (if not able to convert to fractions, like 1, it's just the same whole number, but a negative).
2. For the "Rotate your slope triangle 90 degrees"; seems simple, which I think you should do a reciprocal of the number, and make it a negative, for ie. 3 is a slope, when changed, it becomes -1/3. so the new slope is a negative reciprocal.

Using linear equations, A rental car company charges prices based on the number of days you rent the car will charge $185 if you rent the car for 7 days.
What is a linear equation?A linear equation is an algebraic equation of the form y=mx + b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
Let us consider the number of days = x
The equation when number of days(x) <= 4,
⇒ $50 + $25x1 = y1
If the car is rented for more than 4 days, (x>4)
⇒ $45 + $20x2 = y2
Now, we are to calculate the rent for 7 days,
which equals,
y2 = $45 + $20x2
for x2 = 7,
y2 = $45 + $20 × 7
⇒ 45 + 140

A minor league baseball team plays 94 games in a season. if the team won 16 more than twice as many games as they lost, how many wins and losses did the team have?
The number of wins is 68 ad losses is 26.
How to compute the value?Let the number of losses = l
Therefore, the number of wins will be: = (2 × l) + 16 = 2l + 16
Total games = 94
Therefore we will add the equation
l + 16 + 2l = 94
3l + 16 = 94
3l = 94 - 16
3l = 78
Divide
l = 78/3
l = 26
Losses = 26
Number if wins = 2l + 16 = 2(26) + 16 = 52 + 16 = 68

The equation that come in the process of solving this quadratic equation by completing square method.So, according to the question
We have
x² - 10x + 9 = 0.We have to solve that quadratic equation by completing square method.
So, we know that
In Completing square method, we have to convert this quadratic equation in square form.
So,
x² - 10x + 9 = 0.
Now, by multiplying both sides by the square of the x-coefficient, we get
x² - 10x + 9 + (-10/2)² = 0 + (-10/2)²
x² - 10x + 9 + (-5)² = 0 + (-5)²

which conversion factors are used to multiply to 18 cm/s to get meters per minute? select each correct answer.
The conversion factors are used to multiply to 18 cm/s to get meters per minute is 60s/1m.
What is conversion?The conversion procedure depends on the unique circumstances and the targeted goal. A rule, a contract, technical requirements, or other norms that have been made public may control this. The precision of the initial measurement must not be increased or decreased during some unit conversions from one system to another. Soft conversion is another name for this. It doesn't need altering the way the thing being measured is physically constructed.
A hard conversion or an adaptable conversion, on the other hand, could not be perfect equivalents. In the new system, it converts the measurement to practical and usable numbers and units. Sometimes it entails rearranging the item's parts significantly or changing its size.
18 cm/s means 18 cm in 1 second.
You must change 1 second into a minute and 18 cm into meters when converting 18 cm/s into meters per minute. 18 cm = 18/100 meters.
1 second = 1/60 minutes.
18/100 meters per 1/60 minutes
18/100÷1/60 = 18/100 ×60/1
= 18 ×(60/100) meters per minute
The factor is 60s/100cm, which is equivalent to 60s/1m
