-18u+16u-7=9

-2u - 7 = 9       (combine like terms)

-2u = 16           (add 7 on both sides)

u = -8

Answer:

The correct answer to this problem is u = -8.

Step-by-step explanation:

To solve this problem, we first must combine like terms on the left side of the equation.  This means adding together the two terms that have a "u" multiplied by a number.  To combine them, we simply add the coefficients together, as we would with constant values.  This is modeled below:

-18u+16u-7=9

-2u - 7 = 9

Next, we want to add 7 to both sides of the equation.  This will cancel out the -7 on the left side of the equation, isolating the term with the variable u (what we are trying to solve for).

-2u - 7 + 7 = 9 + 7

-2u = 16

Finally, we want to divide both sides by -2 in order to isolate the variable u.  This will get rid of the coefficient of negative 2 and give us our answer.

u = 16/-2 = -8

Therefore, the answer to this question is u = -8.

Hope this helps!

Answer:

D

Step-by-step explanation:

Find (f + g)(x) then evaluate (f + g)(9)

(f + g)(x) = f(x) + g(x)

= 4x - 1 + x² - 2 = x² + 4x - 3

Now substitute x = 9 into the expression

(f + g)(9) = 9² + 4(9) - 3 = 81 + 36 - 3 = 114 → D

Answer:

J.117

Step-by-step explanation:

f(x) =4x-1

if f(2)= 4(2)-1

f(2)= 8-1 = 7

f(2) = 7 equation 1

g(x) =x2-2

if g(4)= (4)2-2

g(4) = 8-2 = 6 equation 2

Now,

(f+g)(9) =?

subtitute equation 1 and 2

(7+6)(9)=?

(13)(9)=?

13×9= 117

Hence, the answer is 117

I personally prefer to rewrite the inequality so the comparison is to zero. That is done in the second attachment, which rewrites it to ...

  |x| -4 > 0

by subtracting 1 from both sides. It is often easier to read the values of x-intercepts than it is to read the coordinate values where lines cross each other.

Answer:

Distribute

y - 2 = -2x - 8

Move the constant to the other side

y - 2 = -2x - 8

  +2 =        +2

y = -2x - 6

Answer:

s = P - t - r

Step-by-step explanation:

You are solving for the variable, s. To do so, isolate the variable. Note the equal sign, what you do to one side, you do to the other.

First, subtract the variable t from both sides of the equation:

P (- t) = s + t (-t) + r

P - t = s + r

Next, isolate the variable s by subtracting r from both sides:

P - t (-r) = s + r (-r)

P - t - r = s

s = P - t - r

s = P - t - r is your answer.

Answer:

4:24 p.m.

Step-by-step explanation:

Figure out how often the buses leave at the same time. This is the same as the least common multiple (LCM) of how often they leave the stadium.

The LCM is found by multiplying the maximum number of each prime factor found in any of the numbers.

The prime factors of a number are found by dividing it by whole numbers until the factors are all prime. Prime numbers only have the factors 1 and itself.

6 = 2 X 3

8 = 2 X 2 X 2

The greatest times 2 repeats is three times.

The greatest times 3 repeats is one time.

2 X 2 X 2 X 3 = 24

The LCM is 24, and the buses have the same leaving times every 24 minutes.

Find 24 minutes after 4:00 p.m. Change the minutes only, which are the numbers right of the colon : .

The buses will next leave together at 4:24 p.m.

Answer:

  -x^4y^2 +7x^3y^3 +2x^2y^4 -3xy^5

Step-by-step explanation:

The powers of x in the terms of the given expression are ...

so, we want to swap the last two terms to put them in the desired order:

  -x^4y^2 +7x^3y^3 +2x^2y^4 -3xy^5

Answer:

x = 10 and x = -10

Step-by-step explanation:

Given the function

[tex]f(x)=\dfrac{5x^2+3x+6}{x^2-100}[/tex]

This function is undefied when the denominator equals to 0. Find these values for x:

[tex]x^2-100=0\\ \\(x-10)(x+10)=0\\ \\x-10=0\ \ \text{or}\ \ x+10=0\\ \\x=10\ \ \text{or}\ \ x=-10[/tex]

This means that vertical lines x = 10 and x = -10 are vertical asymptotes (the graph of the function f(x) cannot meet these lines because this function is undefined at x = 10 and x = -10)

Answer:

(1) 5 , PI + 2, 17/3

(2) 3/2, sqrt (5), 2.5

(3) Sqrt(5)/2, PI – 2, 5/4

Step-by-step explanation:

For each number, begin by comparing the whole numbers. The one with the least whole number is the smallest while the one with the largest is the biggest number.

If the numbers being compared have the same whole numbers, check the decimal places. Begin with tenths. The one with the lowest number is the smallest number. If they are the same compare the hundredths, if they are the same compare thousandths...until you find a decimal that is different and can differentiate the numbers.

This is B.

Answer:

Option b) is correct

ie., [tex]x=\frac{3\pm \sqrt{5}}{2}[/tex]

Step-by-step explanation:

Given quadratic equation is [tex]x^{2}-3x+1=0[/tex]

To find the solutions of given equation:

Solution of quadratic equation [tex]ax^{2}+bx+c=0[/tex]

[tex]x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}[/tex] where a,b, are coefficients of [tex]x^{2}[/tex] and x respectively and c is constant.

From the given quadratic equation a=1, b=-3 and c=1

Part 1) Equation of a perpendicular line is [tex]y=\frac{2}{3}x+4[/tex]

Part 2) Equation of a parallel line is [tex]y=-\frac{3}{2}x+\frac{21}{2}[/tex]

Step-by-step explanation:

Part 1) Find the equation of the line that is perpendicular to the given line and passes through the point (3, 6).

we have

[tex]y=-\frac{3}{2}x-3[/tex]

The slope of the given line is [tex]m=-\frac{3}{2}[/tex]

Remember that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)

so

The slope of the perpendicular line to the given line is equal to

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

Find the equation of the line in point slope form

[tex]y-y1=m(x-x1)[/tex]

we have

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

[tex]point\ (3,6)[/tex]

substitute

[tex]y-6=\frac{2}{3}(x-3)[/tex]

Convert to slope intercept form

[tex]y=mx+b[/tex]

Isolate the variable y

[tex]y-6=\frac{2}{3}x-2[/tex]

[tex]y=\frac{2}{3}x-2+6[/tex]

[tex]y=\frac{2}{3}x+4[/tex]

Part 2) Find the equation of the line that is parallel to the given line and passes through the point (3, 6).

we have

[tex]y=-\frac{3}{2}x-3[/tex]

The slope of the given line is [tex]m=-\frac{3}{2}[/tex]

Remember that

If two lines are parallel, then their slopes are the same

so

The slope of the parallel line to the given line is equal to

Step-by-step explanation:

The explanatory variable and independent variable are similar terms. When a variable is not at all dependent on any factor then it is called an explanatory variable. So, it must be plotted along the independent axis i.e. x-axis.

On the other hand, a response variable is an alternate term of the dependent variable and in our case height is a corresponding dependent variable of explanatory variable age.

Whitney's speed was 35 miles per hour.

Let's let x represent Whitney's speed in miles per hour (mi/h). Then, Whitney's mother's speed would be x + 5 mi/h. Since time is equal to distance divided by speed, and both Whitney and her mother arrived at the same time, we can set their times equal to each other:

Whitney's time = Distance / Speed = 7 miles / x mi/h

Mother's time = Distance / Speed = 8 miles / (x + 5) mi/h

7/x = 8/(x + 5)

7(x + 5) = 8x

7x + 35 = 8x

x = 35 mi/h

Therefore, Whitney's speed was 35 miles per hour.

Answer:

Part 1) The perimeter of rectangle is equal to 24 units

Part 2) The area of rectangle is equal to 32 square units

Step-by-step explanation:

Part 1) Find the perimeter of rectangle

we know that

The perimeter of rectangle is equal to

[tex]P=2(L+W)[/tex]

where

L is the length of rectangle

W is the width of rectangle

we have

[tex]F(-2,5),R(-2,1),O(6,1),G(6,5)[/tex]

Plot the figure to better understand the problem

using a graphing tool

see the attached figure

Remember that in a rectangle opposite sides are congruent and the measure of each interior angle is equal to 90 degrees

so

[tex]FG=RO=L\\RF=OG=W[/tex]

the formula to calculate the distance between two points is equal to

[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]

step 1

Find the distance FG

[tex]F(-2,5),G(6,5)[/tex]

substitute the values

[tex]d=\sqrt{(5-5)^{2}+(6+2)^{2}}[/tex]

[tex]d=\sqrt{(0)^{2}+(8)^{2}}[/tex]

[tex]FG=8\ units[/tex]

step 2

Find the distance RF

[tex]R(-2,1),F(-2,5)[/tex]

substitute the values

[tex]d=\sqrt{(5-1)^{2}+(-2+2)^{2}}[/tex]

[tex]d=\sqrt{(4)^{2}+(0)^{2}}[/tex]

[tex]RF=4\ units[/tex]

step 3

Find the perimeter

[tex]P=2(L+W)[/tex]

we have

[tex]FG=RO=L=8\ units\\RF=OG=W=4\ units[/tex]

substitute

[tex]P=2(8+4)=24\ units[/tex]

Part 2) Find the area of rectangle FROG

we know that

The area of rectangle is equal to

[tex]A=LW[/tex]

we have

[tex]FG=RO=L=8\ units\\RF=OG=W=4\ units[/tex]

substitute

[tex]A=(8)(4)=32\ units^2[/tex]

The area and the perimeter of the rectangle FROG is evaluated as:

For a rectangle with length and width L and W units, we get:

The shortest distance(straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

The coordinates of the points of the rectangle FROG are given as:

F(-2,5), R(-2,1), G(6,5), and O(6,1) (from its plot, as given below)

FR and RO are length and width pair(we can call any one of them as length and other as width) of the considered rectangle as they are adjacent to each other.

We denote length of a line segment AB by |AB|

Thus, we get:

Now with the help of length and width, we can evaluate its perimeter and area, as shown below:

Step-by-step explanation:

To compare fractions, they need to have the same denominator.  So you need to find the least common multiple (LCM) of 10, 3, and 4.

To find the LCM, first write the prime factorizations.

3 = 3

4 = 2²

10 = 2×5

The LCM is the product of each factor raised to its highest exponent.

LCM = 2²×3×5

LCM = 60

Now we rewrite each fraction with this new denominator.

9/10 = 54/60

2/3 = 40/60

2/4 = 30/60

Answer:

You need to convert the numbers into the same format.

Step-by-step explanation:

If you want to keep them in fraction form, you need to find the least common multiple. This means the smallest number that can be divided by all of the denominators. For this example, the number would be 60, because 60/10 is 6, 60/3 is 2, and 60/4 is 15. Now that we know this, you need to make every denominator 60. You do this by multiplying the numerator by whatever you needed to multiply the denominator by to get 60. For example, you need to multiply 10 by 6 to get sixty, so you would multiply 9 by 6 as well. You would repeat this pattern with all of the numbers, getting 54/60 (9/10), 40/60 (2/3), and 30/60 (2/4). This makes it very easy to tell which is the larger number.

If you don't want to do all of that, you can use decimal form. To find what each number would be in decimal form, divide the numerator by the denominator. For example, 9 divided by ten is .9, 2 divided by 3 is .66..., and 2/4 is .5.

The median of given data is 42.5

And

The median after replacing 42 with 92 is 44.5

Step-by-step explanation:

A median is the middle value of the data that divided the data in two equal parts

Given data is:

46 43 39 48 52 40 42 98 20 38

First of all, the data has to arranged in ascending order

20, 38, 39, 40, 42, 43, 46, 48, 52, 98

As the number of values is even, n=10, the median will be the average of middle two numbers

20, 38, 39, 40, 42, 43, 46, 48, 52, 98

[tex]Median = \frac{42+43}{2}\\=\frac{85}{2}\\=42.5[/tex]

The median is 42.5

Now,

Replacing 42 with 92

20, 38, 39, 40, 92, 43, 46, 48, 52, 98

The data has to be re-arranged

So,

20, 38, 39, 40, 43, 46, 48, 52, 92, 98

As the number of values is same,

[tex]New\ median = \frac{43+46}{2}\\=\frac{89}{2}\\= 44.5[/tex]

Hence,

The median of given data is 42.5

And

The median after replacing 42 with 92 is 44.5
