Answer:

7. [tex](f+g)(x) = 6x - 2[/tex]

8. [tex](f-g)(x) = 2x + 8[/tex]

Step-by-step explanation:

We are given two function, f(x) and g(x).

We want to find their addition and their subtraction, and we do this combining like terms.

The functions are:

[tex]f(x) = 4x + 3[/tex]

[tex]g(x) = 2x - 5[/tex]

7. Find (f+9) (x)

[tex]4x + 3 + 2x - 5 = 4x + 2x + 3 - 5 = 6x - 2[/tex]

So

[tex](f+g)(x) = 6x - 2[/tex]

8. Find (f - g) (x)

[tex]4x + 3 - (2x - 5) = 4x + 3 - 2x + 5 = 4x - 2x + 3 + 5 = 2x + 8[/tex]

So

[tex](f-g)(x) = 2x + 8[/tex]

Answer:

   slope = 10

Step-by-step explanation:

Examination of the values shows you that each y-value is 10 times the corresponding x value. That means the slope is 10. (If the ratios were different, then the slope formula would need to be used. The fact that they are all the same means y is proportional to x.)

__

You can use the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (40 -20)/(4 -2) = 20/2

  m = 10

The slope is 10.

Answer:

x = -3

Step-by-step explanation:

Notice that the addition of angle <CDH plus angle <HDE have to give the measure of angle <CDE (which is 144 degrees as stated in the problem)

Then, we can say in equation form:

<CDH + <HDE = 144

replacing with their expressions in terms of x:

x + 93 + 57 + x = 144

solving for x:

2 x + 150 = 144

2 x = 144 - 150

2 x = - 6

x = -3

Answer:

Step-by-step explanation:

Welp, we gotta solve for the solutions

Step 1

3(-2x + 4) = -6x – 12  Simplify

Step 2

3(-2x + 4) = -6x – 12  subtract 12 from the sides

-6x+12-12=-6x-12-12

-6x=-6x-24

Step 3

-6x=-6x-24  add 6x to the sides

-6x+6x=-6x-24+6x

Answer:

The Fundamental Graphing Principle for Functions says that for a point (a, b) to be on the graph,

f(a) = b. In particular, we know f(0) = 1, f(2) = 3, f(4) = 3 and f(5) = 5. Suppose we wanted to

graph the function defined by the formula g(x) = f(x) + 2. Let’s take a minute to remind ourselves

of what g is doing. We start with an input x to the function f and we obtain the output f(x).

The function g takes the output f(x) and adds 2 to it. In order to graph g, we need to graph the

points (x, g(x)). How are we to find the values for g(x) without a formula for f(x)? The answer is

that we don’t need a formula for f(x), we just need the values of f(x). The values of f(x) are the

y values on the graph of y = f(x). For example, using the points indicated on the graph of f, we

can make the following table.

x (x, f(x)) f(x) g(x) = f(x)

In general, if (a, b) is on the graph of y = f(x), then f(a) = b, so g(a) = f(a) + 2 = b + 2. Hence,

(a, b+ 2) is on the graph o

main role x (x, f(x)) f(x) g(x) = f(x) + 2 (x, g(x))

Answer:

UY = 90

GH = 4

Step-by-step explanation:

Property of similarity of two similar figures:

"If two figures are similar, their corresponding sides are proportional"

Since, FGHIJ ~ YUVWX

[tex]\frac{FG}{UY}= \frac{GH}{UV}= \frac{IJ}{WX}[/tex]

[tex]\frac{10}{UY}= \frac{GH}{36}= \frac{6}{54}[/tex]

[tex]\frac{10}{UY}= \frac{6}{54}[/tex]

UY = [tex]\frac{54\times 10}{6}[/tex]

UY = 90

[tex]\frac{GH}{36}= \frac{6}{54}[/tex]

GH = [tex]\frac{6\times 36}{54}[/tex]

880 just took the test

Step-by-step explanation:

Answer:

880 is correct

Step-by-step explanation:

if the mean is 800 and the standard deviation is 40, she needs two of the standard deviation added to 800. Which makes the equation: 800 + 40 + 40 which equals 880.

Step-by-step explanation:

Hello!

[tex]\large\boxed{(4, -150)}[/tex]

We can solve for the vertex by completing the square. Begin by factoring out 6 from the equation to simplify the process:

6(x² - 8x) - 54 = 0

To complete the square, we must look at the first two terms (x² - 8x).

Remember that squaring a binomial uses the format a² + 2ab + b². We are already given a² and 2ab², so solve for b:

-8 / 2 = -4. This is the value of b.

We can rewrite this as:

(x - 4)²

However, this produces +16 which much be taken into account. Substitute (x - 4)² into the original equation:

6(x - 4)² - 54 = 0

Multiply 16 by the term in the front and subtract to cancel out this term:

6(x - 4)² - 54 - (6 · 16) = 0

Simplify:

6(x - 4)² - 150 = 0

In this form, the vertex is given as:

a(x - h)² + k, where h = x-coordinate and k = y-coordinate of the vertex.

In this instance, h = 4 and k = -150, so the coordinates of the vertex are:

(4, -150)

Answer:

y = 6x²-48x-54 has a vertex at (4,-150)

Step-by-step explanation:

There is no vertex. The solution set to 6x²-48x-54 = 0 is two points, (-1,0) and (9,0).

If you mean y = 6x²-48x-54, that is an up-opening parabola.

Put the equation into vertex form:

y = 6x²-48x-54

 = 6(x²-8x)-54

 = 6(x²-8x+4²)-6·4²-54

 = 6(x-4)² - 150

vertex at (4,-150)

Answer:

A, C, and E

Step-by-step explanation:

To solve the equation, you would divide both sides by 5 to get t alone. the remaining equation would be t=35.

To figure out t, you need to do division, therefore the scenario requires division.

A. You can do 175 tons of food ÷ 5 tons a day. t represents the number of days. Therefore, 175÷5=35 days. (division)

B. This would be $175 - $5 since Thomas gave his sister $5. Thomas is left with $170 in winnings. (subtraction)

C. 175 minutes are used to grade 5 tests. 175 minutes ÷ 5 tests = 35 minutes spend grading 1 test. (division)

D. Mary's bookshelf holds 175 books and the top shelf only holds 5. Therefore, 175 books - 5 books on the top shelf = 170 books on the bottom shelf (unless there are more shelves). (subtraction)

E. 175 days ÷ 5 gallons of paint a day. 175÷5 = 35 gallons of paint used. (division)
