Which equation is the inverse of y=9x^2-4

(1)

we are given two points

A=(-3,-4)

B=(2,0)

and point P [tex](-1, -\frac{12}{5} )[/tex] partitions AB

Let's assume it partitions into m:n

so, we get

[tex]\frac{AP}{PB}=\frac{m}{n}[/tex]

so, we can write our point as

[tex](-1,-\frac{12}{5} )=(\frac{2m-3n}{m+n},\frac{0m-4n}{m+n})[/tex]

now, we can set x-value to x-value

and y-value to y-value

and then we can solve for m and n

[tex]-1= \frac{2m-3n}{m+n}[/tex]

[tex]-\frac{12}{5} =\frac{0m-4n}{m+n}[/tex]

now, we can solve for m/n

[tex]-m-n=2m-3n[/tex]

[tex]3m=2n[/tex]

[tex]\frac{m}{n} =\frac{2}{3}[/tex]

so, option-C.........Answer

Infinitely many solutions.

To solve this problem, we set up equations based on the fact both boys cover the same distance in the given time. Taking Matthew’s speed as ‘x’, we find that 'x' equals 40 yards per minute, meaning Matthew’s speed is 40 yards per minute and Lowe’s is 120 yards per minute.

The scenario can be resolved by employing the concepts of rate, time, and distance. Here, we need to recognize that 'rate' stands for the speed at which each boy is moving, 'time' signifies the duration in which Lowe overtakes Matthew, and 'distance' represents how far Matthew was when Lowe started pursuing him.

In this instance, Lowe's speed is stated to be three times faster than Matthew's speed. Since both boys are present in the same place after 30 minutes (when Lowe overtakes Matthew), we can say that they've both traveled the same distance. We can state this mathematically as:

Matthew's speed * 30 minutes = 1200 yards, and Lowe's speed * 30 minutes = 1200 yards

As we know that Lowe's speed is three times Matthew's speed, let's consider Matthew's speed as 'x'. As a result,

Lowe's pace becomes '3x'.

Because both equations equal 1200 yards, we may set the two equations equal to each other and solve for 'x':

x * 30 = 3x * 30

Dividing both sides by 30 yields 'x' = 40 yards per minute. Therefore, Matthew's speed is 40 yards per minute, and Lowe's speed is 3x, or 120 yards per minute.

Final answer:

To find the average speed of the big airplane that leaves after the small airplane, calculate the time the small airplane took to cover the distance and then use that to find the time the big airplane spent traveling to determine its speed. The average speed of the big airplane is 500 mph.

Explanation:

The average speed of the small airplane can be calculated using the formula:

Speed = Distance / Time

Given that the small airplane travels 625 miles at an average speed of 250 mph, the time taken is 625 / 250 = 2.5 hours. As the big airplane leaves 1.25 hours later and both planes arrive at the same time, the big airplane traveled for 2.5 - 1.25 = 1.25 hours. The average speed of the big airplane can be calculated as 625 miles / 1.25 hours = 500 mph.

no because the first five equals 5000

the second 5 equals 500

the third 5 equals 50

and the fourth 5 equals 5.

To find the number of times greater, let us divide 5.3 by 0.53.

Number of times greater = [tex]\frac{5.3}{0.53}[/tex]

[tex]=\frac{5.3}{0.53}(\frac{100}{100} )[/tex]

[tex]=\frac{530}{53}[/tex]

Hence, 5.3 is 10 times greater than 0.53.

The measure of angle 4 will be 42 degrees because corresponding angles are equal when two lines are cut by a transversal, and in this case, angle 5 and angle 4 are corresponding angles.

The concept involved here is that corresponding angles are equal when two lines are cut by a transversal. In the given problem, angle 5 and angle 4 are corresponding angles because they occupy the same relative position at an intersection of a transversal and two lines. Therefore, if the measure of angle 5 (m angle 5) is 42 degrees, then the measure of angle 4 (m angle 4) will also be 42 degrees.

If you have to find x-intercept, then you have to equate y to 0. Thus,

when y=0, x+2·0=5 and x=5.

Point (5,0) is x-intercept.

Answer: (5,0)

The x-intercept of the graph is:

                                5

and the point where it is obtained is (5,0)

We know that the x-intercept of a graph is the x-value of the point where it's y-value is zero.

Similarly the  y-intercept of a graph is the y-value of the point where it's x-value is zero.

We are given a equation of a line as:

             [tex]x+2y=5[/tex]

Hence, when y=0 in the equation we get:

 [tex]x=5[/tex]

Hence, the point where the x-intercept is obtained is: (5,0)

and the x-intercept of the graph is: 5

First, we start with the product

so _________ * _________

The square root of 300 is approximately 17.32, placing it between the integers 17 and 18. The square of 17 is 289, and 18 is 324, confirming this placement.

The square root of 300 falls between two consecutive integers. To find the closest integers, we can estimate the square root's value. The square root of 300 is approximately 17.32, as 17 squared is 289 and 18 squared is 324. Therefore, the square root of 300 is greater than 17 but less than 18.

In terms of integers, the square root of 300 is between 17 and 18. These are the closest integers that the square root of 300 falls between.

To further validate this, we can square both 17 and 18. The square of 17 is 289 (less than 300), and the square of 18 is 324 (greater than 300). This confirms that the square root of 300 indeed lies between 17 and 18.

In summary, the closest integers that the square root of 300 falls between are 17 and 18.

The easy way to do this is:

Since the radius of the second circle is exactly 6 times the radius of the first circle, you could just multiply the circumference by 6:

9.42 x 6 = 56.52!  But let's double-check.

9 x 2 = 18    So, the diameter is 18.

18 x 3.14 = 56.52!     So, 56.52 is the correct answer!

Remark

The formula you should be using is

C = k*r because this is a variation question. There are ways of doing this without solving for k, but it is a good idea to solve for k first.

Givens

C = 9.42

r = 1.5

k = ??

K =

C = k*r

9.42 = k * 1.5

k = 9.42/1.5

k = 6.28 which is what it should be given that pi = 3.14. But you must check.

r = 9

C = k*r

C = 6.28 * 9

C = 56.52 which rounded = 57 to the nearest inch

Answer:

Hey there! The correct answer would be x=-4.

Step-by-step explanation:

To start, you would first need to combine your like terms, terms that are not only raised to the same power but also have the same exact variables. In this case, your like terms are -6x and -11x:

-6x-11x=68 --> -17x=68

Now, divide both sides by -17 in order to isolate your variable term:

-17x/-17 = 68/-17

x=-4

Therefore, your answer would be x=-4.

To check to make sure this answer is right, plug -4 in for x and see if the result is 68=68:

-6(-4)-11(-4)=68

24+44=68

68=68
