What is the value of f1(7)?

Answer:

The wording of this question is vague.  Are the numbers 3.4, 2.2, and 4.6 the weights in pounds (lbs) of the individual items carried by each hiker?  I will assume that each of x hikers carries 3 items of weights 3.4, 2.2, and 4.6 lbs, and I will assume that you seek the total weight W carried by the group of x hikers.

W = (number of hikers)(pounds carried by each hiker) = x(3.4 + 2.2 + 4.6) lbs.

There is not much more i can tell you without additional information or clarification.

Step-by-step explanation:

Answer: d, f

Answer:

Step-by-step explanation:

1). Replace one equation with a multiple of itself.

2x + 7y = 3 ⇔ 4(2x) + 4(7y) = 4(3)

2). Yes, systems are equivalent.

Answer:

Step-by-step explanation:

(2x -3y + 5z) - (-4x -y +8z)

6x-2y-3z  combine terms With the - in between, it changes the signs to the opposite in the second ()

[tex]y = - \frac{1}{2} x + 9[/tex]

since the slope-intercept equation is y=mx+b

m represents the slope

b represents the y-intercept

19 mph + 14 mph = 33 mph

198 miles / 33 mph = 6 hours

It will take them 6 hours to meet.

im pretty sure it's 6 hours

hopefully you get it right :)

Answer: 2 miles per hour

Step-by-step explanation:

Answer:

Step-by-step explanation:

we call one side x and the other side 4x-7. Because in a rectangle opposite sides are equal we can now set up an equation.

x + x + 4x-7 +4x-7 = 180

              10x - 14 = 180

                   10x = 194

                    x = 19.4

the lenght of the other side is 4(19.4)-7 = 70.6

Answer:

n = -7-5i

Step-by-step explanation:

This is the inverse property of addition

Answer:

0.4 times .7 equals .28. So e = .7

Step-by-step explanation:

Ok, so you got the parent function y = x^2 and it changed to y = x^2 -8

#'s inside the parenthesis would move it left or right and #'s outside the parenthesis would move it up or down. Since there are no parenthesis the x coordinate is 0, hence it doesn't move left or right. Because of this we know that the graph will be moved up or down. Now we look to see is the # negative or positive. If negative, we move it down. If positive, we move it up. Looking at this problem, we see that it will move it down. Next look at the #. This will indicate how much you will move the graph. In this problem, we will move the graph down 8.

Therefore,

When you change the graph y = x^2 to y = x^2 -8, you are moving the graph down 8.

Answer: So if the equation change the graph as y=x^2-8 the graph will move 8 points down.

Darius can buy 16 heads of cabbage

Step-by-step explanation:

28.80 divided by 1.80 is equal to 16.

Answer:

It is C

Step-by-step explanation:

To get the new coordinates you would move the shape up the y-axis 8 times, and right on the x-axis 8 times as well.

Answer:

C

Step-by-step explanation:

You can either compare two similar points or just count the units on the graph

Answer:

I believe the answer is 3. AM = MB

Step-by-step explanation:

For the first option, 1/2 of AB is obviously equal to AM. Therefore, the second option is also correct.

As far as the fourth option, CD equals AB since a compass was used to gather the points, ensuring they are equidistance.

Answer:

in about 0.92 hours or 55.2 minutes

Step-by-step explanation:

The time they take to paint the room:

Pragnesh and Qazi  = 2 hours

Pragnesh and Ronghui = 3 hours

Qazi and Ronghui = 4 hours

Meaning, each hour (1)  they'll paint:

Pragnesh and Qazi  =  [tex]\frac{1}{2th}[/tex] of the room

Pragnesh and Ronghui = [tex]\frac{1}{3th}[/tex] of the room

Qazi and Ronghui = [tex]\frac{1}{4th}[/tex] of the room

By summing all their work abilities we can determine how long it would take if all three students worked together to paint the fence, which is:

[tex]\frac{1}{2} + \frac{1}{3} + \frac{1}{4} = \frac{13}{12th}[/tex] of the room each hour. Therefore the whole (1) room would be painted in 1 ÷ [tex]\frac{13}{12}[/tex] = [tex]\frac{12}{13} hours[/tex] or 0.92 hours or 55.2 minutes (0.92 * 60).

Answer:

Step-by-step explanation:

Answer:It would cost $11.70 for 2.25 pounds of gummy worms.

Step-by-step explanation:

$2.60*4=$10.40 for 2 pounds

$2.60/2=$1.30 for 1/4 of a pound which is equal to 0.25

$10.40+$1.30=$11.70 for 2.25 pounds of gummy worms

Answer:

Juan does not have enough lumber to make the five shelves.

Step-by-step explanation:

Let assume that:

If Juan bought a piece of lumber that is 18 feet long.

and the bookcase will have = 5 shelves

Also, the length of each bookcase = 2 1/2 long = 2.5 long

Then the amount required for the five shelves = 5 × 2.5

= 12.5 feet long

Therefore, we can say Juan does not have enough lumber to make the five shelves.

Hence, he will need an addition of: (18 - 12.5) feet = 5.5 feet piece of lumber

Answer:

Step-by-step explanation:

In an equation, the additive property of equality states that if we add or subtract the same number to both sides of an equation, the sides remain equal.

transitive property,  If a = b and b = c, then a = c.

Segment Addition Postulate Defined. The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation AB + BC = AC.

Answer:

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

General Formulas and Concepts:

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

Step-by-step explanation:

Step 1: Define points

(3, 5)

(6, 7)

Step 2: Find slope m

m = y2 - y1 / x2 - x1

substitute values (3,5) , (6,7)

m = 7 - (5) / 6 - (3)

simplify

m = 2/3

Answer:

6

Step-by-step explanation:

Remember PEMDAS. This will help you a lot in algebra.

P Parenthesis

E Exponents

M Multiplication

D Division

A Addition

S Subtraction

This is the order of how all the operations should take place.

Note: Multiplication and Division happen together. Just go from left to right. This is the same for Addition and Subtraction.

Onto the problem!

First, look at PEMDAS.

P stands for Parenthesis so first we look for those.

In this case, we have a set here. Solve whatever is inside.

[tex]\frac{1}{2}*(4+8)[/tex]

[tex]\frac{1}{2}*(12)[/tex]

Next, look for Exponents. There aren't any in this expression, so we're okay to move on.

Now, look for Multiplication or Division.

[tex]\frac{1}{2}*(12)[/tex]

[tex]6[/tex]

The answer is 6.

I really hope this helped you! Asking for help is a great first step in math! Keep at it and I'm sure you'll succeed. :)

Answer:

6

Step-by-step explanation:

Answer:

-24 = 3x + 9

-24 - 9 = 3x

-33 = 3x

-33/3 = x

-11 = x

x = -11

Add 9 to both sides

So

-15=2x

Divide both sides by 2

So

X=-7.5

Hope this helps!
