Answer:

No solution

Step-by-step explanation:

You can solve this in a few ways. One way is to graph the equation, and the solution is the x-value of the point of intersection. Another way would be to factor, which is more difficult to complete with a square bigger than 2.

By graphing, you can see a parabola that never touches that x-axis, which means no solution.

Answer:

  21

Step-by-step explanation:

You want the value of the expression 2f(-3)-f(4), given that f(x) = 3x²-x+ 5.

A function is evaluated by putting the argument where the variable is, and simplifying the result. Polynomials are often easier to evaluate if they are written in Horner form.

  f(x) = 3x² -x +5

  f(x) = (3x -1)x +5

The values we need are ...

  f(-3) = (3(-3) -1)(-3) +5 = (-10)(-3) +5 = 35

  f(4) = (3(4) -1)(4) +5 = (11)(4) +5 = 49

Then the expression of interest has the value ...

  2f(-3) -f(4) = 2(35) -49 = 70 -49

  2f(-3) -f(4) = 21

The number of hits A got is 186 hits.

​A player's batting average is calculated by dividing the number of hits by the number of at-bats.

Player A batting average =  0.312

Number of at-bats A did =  596

We have to find the number of hits A got.

0.312 = Number of hits / 596

Number of hits = 0.312 x 596

                        = 185.952 hits.

Rounding to a whole number we get,

= 186 hits

Thus, the number of hits A got is 186 hits.

Answer: x=6

Step-by-step explanation: (x+54)+5x=90 -> 6x+54=90 -> 6x=36 -> x=6

you know it equals 90 because it's on a 180 and there's a right angle.

simplify the equation to 6x+54=90, subtract 54 from 90, and divide by 6 to isolate x.

The prediction method Linear Extrapolation is the method used to estimate a point on a line when the point does not lie between the given points.

Using the equation of a line to obtain a new data point based on an existing collection of data points is known as linear interpolation in mathematics.

Now,

Since it employs a linear model to forecast the necessary point that does not reside between the given locations, this prediction technique is known as linear extrapolation.

The numerical value in this sentence, "the average price of a house in the new subdivision is $257,000" describes a Population Parameter.

A population parameter is a figure that describes a fact about a whole population. In this sentence, we can see that the figure quoted is representative of an entire population. A sample statistic, on the other hand, describes something about a part of a population.

So, for the statement above, we can see that the average price is representative of all the houses in the new subdivision. Thus, the figure is a population parameter.

The graph of the given linear function can be seen in the image below.

Here we want to graph the line:

y = 3x - 2  (I think this is the line, the image is really blurry).

To graph this line (or any line, actually) what you need to do is find two points on the line.

To do so, you need to evaluate the function.

If we use x = 0, then:

y = 3*0 - 2 = -2

So we have the point (0, -2)

If we use x = 1, then:

y = 3*1 - 2 = 1

So we have the point (1, 1)

Now just graph these two points, and then draw a line that passes through both of them, you should get something like the image below.

Answer: GoodMorning: )✨Ok so We should Know that The top number in a fraction is always considered a numerator, and that It shows the number of parts we have. The bottom number in a fraction is considered a denominator. It shows the total number of parts into which anything is divided. For example, in the fraction 8/7, 8 is the numerator and 7 is the denominator.

Step-by-step explanation:  Like In this fraction 7/3, 7 is the numerator and 3 is the denominator. In the fraction 9/7, 9 is the numerator and 7 is the denominator.The value placed above the horizontal line in a fraction is called a numerator. It signifies the number of parts taken out of the whole. The numeric value below the vinculum of a fraction is called the denominator. It represents the total number of equal parts as a whole.

Now, as per the question;

The total number of bulbs be 120 and each bulb is working as independent event.

The reliability of each bulb is 99.9% = 0.999

Let 'p' the probability the bulb will work.

The probability that all will work = p¹²⁰

The probability that all will work = (0.999)¹²⁰ = 0.886

Answer:

Equation: 0.11x + 0.05(10500 - x) = 945

$7000 was invested at 11% and

$3,500 was invested at 5%

Step-by-step explanation:

There are two equations needed

Let x = amount of money invested at 11%
11% = 11/100 = 0.11 in decimal
Interest at 11% for 1 year = 0.11x

Amount of money invested at 5% interest. 5% = 0.05

= 10500 - amount invested at 11%= 10500 - x

Interest from this amount after 1 year = 0.05(10500 - x)

Total of these two = 945

So 0.11x + 0.05(10500 - x) = 945

The equation based on the information as it is given:

0.11x + 0.05(10500 - x) = 945

We know the total interest obtained was $945 so we have the equation
0.11x + 0.05(10500- 5x) = 945

Simplify

0.11x  + (525 - 0.05x) = 945
==>0.11x + 525 - 0.05x = 945

==> 0.06x = 945 - 525

==> 0.06x = 420

==> x = 420/0/06 = $7000

Amount invested at 11% interest is $7,000

Amount invested at 5% interest = 10,500 - 7,000 = $3,500

According  to the given data the slope mpq of the secant line pq  for the following values of x are :

The slope is defined as the proportion of both the vertical difference of two points, known as the rise, towards the horizontal change between those same two points, known as the run.

Calculate the values of two line points. Determine the difference in y-coordinates between these two locations (rise). Calculate the x-coordinate distinction between these two locations (run). Divide the x-coordinate variation (rise/run or slope) by the y-coordinate difference.

Slope(m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Clyde and Mason are 432 mi apart from each other in distance.

We are given that:

Clyde and mason can each leave a rest area on the Florida turnpike.

Clyde travels north whereas Mason travels south.

After 4 hr., we get that Clyde has gone 248 mi and Mason, due to the heavy traffic he got , traveled only 184 mi.

We need to tell how far are they from each other.

We will do this by addition.

Distance = 248 mi + 184 mi

Distance = 432 mi.
