What is the value of x in the solution to this system of equations?
3x-5 y=22
y=-5x+ 32

x+1 for the given scores is 11.

To find  x+1 for the given scores, we need to sum up the scores and add 1 to the sum. Let's calculate step by step:

Step 1: Add up the scores.

3+0+5+2=10

Step 2: Add 1 to the sum.

10+1=11

So, x+1 for the given scores is 11.

Let's break down the steps for clarity. In Step 1, we simply add up the scores provided: 3, 0, 5, and 2. The sum of these scores is 10.

In Step 2, we add 1 to the sum obtained in Step 1. So, 10 + 1 equals 11.

Therefore, x+1 for the given scores is 11.

The value of r is 8 for the points to have a slope of -4.

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope of the line is also defined as the ratio of the rise and the run.

The slope is calculated by the formula below,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that the points are (5, 9) and (r, –3) and the slope is -4. The value of the unknown number will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

-4 = ( -3 - 9) / ( r - 5 )

-4r + 20 = -12

-4r = -32

r = 32 / 4

r = 8

Therefore, the value of r is 8 for the points to have a slope of -4.

Answer:

(-6 , 3)

Step-by-step explanation:

Co-ordinates of A = (-9,-1)

So let x¹ = -9 & y¹ = -1

Co-ordinates of B = (-3,7)

So let x² = -3 & y² = 7

According to Section formula ,

\((x',y') = ( \frac{mx^2 + nx^1}{m + n} ,\frac{my^2 +ny^1}{m + n} )\)

where (x' , y') are the co-ordinates of the point which divides a line segment internally & (m , n) are the ratios in which the line is divided into.

As we have to find the co-ordinates of mid-point of AB , here m = n = 1 (∵ A mid-point always divides a line segment into 2 equal parts. Hence the ratio of length of both lines will be 1 : 1 )

Putting the values in the above formula gives :

\((x' , y') = (\frac{-3-9}{1+1} , \frac{7-1}{1+1} ) = (\frac{-12}{2} , \frac{6}{2} ) = (-6 , 3)\)

∴ Co-ordinate of M = (-6 , 3)

Answer:

\(x=\frac{e^7-3}{7}\)

Step-by-step explanation:

4* ln(7x+3) + 12 = 40

4* ln(7x+3) + 12 - 12 = 40 - 12

4* ln(7x+3) = 28

ln(7x+3) = 28/4

ln(7x+3) = 7

e^7 = (7x + 3)

e^7 - 3 = 7x

\(x=\frac{e^7-3}{7}\)

Answer:

Y=(x+10)^2-105

Step-by-step explanation:

y=x^2+20x-5

y+?=x^2+20x+?-5

y+?=x^2+20x+100-5

y+100=x^2+20x+100-5

y+100=(x+10)^2-5

y=(x+10)^2-5-100

The solution to the differential equation x dx + dy = y + x²- y², with the initial condition y(e) = 1, is x = y + xln(x) - 1.

To solve the differential equation xdx + dy = y + x² - y², we can rewrite it as:

xdx + (y² - y)dy = x²dy.

Integrating both sides, we get:

∫xdx + ∫(y² - y)dy = ∫x²dy.

Integrating the left side:

(1/2)x²+ (1/3)(y³ - y²) = (1/2)x² + C.

Simplifying the equation, we have:

(1/3)(y³ - y²) = C.

Now, we can solve for y:

y³- y² = 3C.

To solve dx/dy = y + xln(x)/y, we can rewrite it as:

dx/dy = y/y + xln(x)/y,

dx/dy = 1 + (xln(x))/y.

Separating the variables, we get:

dx = (1 + (xln(x))/y)dy.

Integrating both sides, we have:

∫dx = ∫(1 + (xln(x))/y)dy.

x = y + xln(x) + C.

Using the initial condition y(e) = 1, we can substitute it into the equation:

e = 1 + elne + C,

e = 1 + e + C,

C = -1.

Therefore, the solution to the differential equation dx/dy = y + xln(x)/y, with the initial condition y(e) = 1, is:

x = y + xln(x) - 1.

Answer:

Yes, Mina is correct

Step-by-step explanation:

Let the triangles be A and B

Given

Triangle A:

\(Angles = 34, 57\)

Triangle B:

\(Angles = 89, 57\)

Required

Is Mina's claim correct?

First, we calculate the third angle in both triangles.

For A:

\(Third\ Angle = 180 - 34 - 57\)

\(Third\ Angle = 89\)

For B:

\(Third\ Angle = 180- 89 - 57\)

\(Third\ Angle = 34\)

For triangle A, the angles are: 34, 57 and 89

For triangle B, the angles are: 34, 57 and 89

Since both triangles have the same angles, then by the postulate of AAA (Angle-Angle-Angle), the triangles are similar.

The probability that the life span of the monitor will be more than 17,340 hours is approximately 0.0359, rounded to four decimal places.

We can use the standard normal distribution to solve this problem by standardizing the value of 17,340 hours to a z-score:

z = (17340 - 15000) / 1300 = 1.8

Using a standard normal distribution table or calculator, we find that the probability of getting a value greater than 1.8 is 0.0359.

Therefore, the probability that the life span of the monitor will be more than 17,340 hours is approximately 0.0359, rounded to four decimal places.

Answer:

Step-by-step explanation:

To determine the amount the player should win in a fair game, we need to calculate the probability of winning and then find the appropriate amount to be won.

First, let's consider the possible outcomes:

1. The game is lost if the first roll results in an odd number (3 possibilities: 1, 3, 5).

2. The game is won if the first roll results in an even number, and the second roll matches the first (3 possibilities: 2, 4, 6).

The probability of winning can be calculated as the probability of the second roll matching the first, which is 1/6 since there are six equally likely outcomes for each roll.

To make the game fair, the expected value of the winnings should be zero. In this case, the player loses the amount paid to play the game if they lose, and they win an unknown amount if they win. Since the probability of winning is 1/6, the amount won should be 6 times the amount paid to play the game.

Therefore, in a fair game, the player should win 6 times the amount paid to play.

The rate of the slower car is 152 km/hr.

Given:

two cars leave towns 340 kilometers apart at the same time and travel toward each other. one car's rate is 18 kilometers per hour less than the other's. if they meet in 2 hours.

Let x be the rate of slower car.

We have two cars heading towards each other. They start 340 km apart and meet up 2 hours later. This means that they are traveling:

340 / 2 = 170 km/hr towards each other.

If the two cars were traveling the same speed, they'd both be going:

170 / 2 = 85 km/hr

We know that one car is traveling 18 km/hr faster than the other car. One way we can account for this is to  ± 9 km/hr to the average speed:

85 ± 9 = 94 , 76 km/hr

rate of slower car x = 84 - 9 * 2

x = 76 * 2 km/hr

= 152 km/hr

Therefore The rate of the slower car is 152 km/hr.

Based on the information provided, it can be concluded that Houa can drive 125 miles for 7 gallons of gas.

To determine the number of gallons this person can drive, just observe the graph presented and determine the value of Y (miles driven) when the value of x (gallons of gas) is 7. Based on this principle it can be concluded that for 7 gallons Houa can drive 125 miles.

This implies that if we compare both cars (Houa's and Lincoln's), the car that requires less gasoline is Lincoln's car.

The inverse of y = x² + 15 is not a function because it fails the vertical line test, which states that a vertical line should intersect the graph of a function at most once.

To find the inverse of the given function y = x² + 15, we can follow these steps:

Step 1: Replace y with x and x with y: x = y² + 15.

Step 2: Solve this equation for y. Rearranging the equation gives us: y² = x - 15.

Step 3: Take the square root of both sides: y = ±√(x - 15).

Since we have a ± symbol in the equation, it indicates that the inverse is not a function. A function requires that each input value (x) corresponds to a unique output value (y). However, in this case, a single value of x can yield two possible values of y due to the ± symbol.

Therefore, the inverse of y = x² + 15 is not a function because it fails the vertical line test, which states that a vertical line should intersect the graph of a function at most once.
