What is 2x - 3 if x equals 7?

Answer:

1. The heavier the dogs are, the shorter lifespan they have.

2. The lifespan of a bloodhound is on average 10 years long

3. Number 2

Step-by-step explanation:

#1 explination: Since its obvious that the graph angles downwards as it goes towards the left, and because as you go to the left you get heavier dogs, put 2 and 2 together and you get my answer.

#2 explination: We see 3 dots around 90 pounds, one that lives 11 years, and 2 that live 10 years. Since we need to be accurate, we need to find the average of 10, 11, and 10. (10+10+11)/3=10.33. Now we round to 10, so 10 is our answer.

#3 explination: Since there is a bloodhound that lives to be 14, we have two answers, 2 or 3. 1 doesn't work since if Alfonso doesn't have good estimation, the first two questions wouldn't matter *the more you know*. Since we see no unusual pattern between any of the three dots I mentioned earlier, Dani must of forgotten her dog's age (probably because of that dog years thing.)

Answer:

3n−32=7n+28

n=-15

Step-by-step explanation:

Let's solve your equation step-by-step.

3n−32=7n+28

Step 1: Subtract 7n from both sides.

3n−32−7n=7n+28−7n

−4n−32=28

Step 2: Add 32 to both sides.

−4n−32+32=28+32

−4n=60

Step 3: Divide both sides by -4.

−4n/−4=60/−4

n=−15

Answer:

4x - 16

Step-by-step explanation:

5.5x + 1 - (1.5x + 17)

5.5x + 1 -1.5x -17

Combine like terms

4x + 1 -17

4x -16

The Simplified Expression is 4x - 17.

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

Given:

5.5x + 1−(1.5x+17)

Now, simplifying the expression

5.5x + 1 - 1.5x - 17

Now, combining the like terms

= (5.5 x - 1.5x ) + 1 - 17

= 4x - 17

Answer:

I can't see three but I'll answer the first two.

Step-by-step explanation:

Number one: The first, third, and fifth options are correct,

Number two: A is correct because if you divide 3/4 you get 0.75. Check by multiplying 0.75 for one by 4 and you get three dollars.

So for three, one pound of pears costs two dollars. That is consistent with the graphs. Pick the answer that states that the best.

Answer:

A. 2

B. 3

Step-by-step explanation:

Remember that the slope of a function is rise over run, or change in y over change in x

The "formula" for this would be [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where you're plugging in the values of the corresponding points (x1, y1) and (x2, y2)

I know all the x's and y's seem confusing but it'll make more sense once we actually apply it

Let's actually start with function b, since there is a graph to help you visualize this. The slope is how many squares up the line travels after going right 1 square. For example, look at the point (1,1) and count how many squares up it goes until the next point (2,4)

Its 3 squares up! and from (1,1) to (2,4) we've moved to the right only one square

so per every 1 square to the right, we move up 3

3/1 = 3, so the slope for b is 3

Note that you can do this with any two points on this graph, so if you started with the same point (1,1) and this time you counted all the way to (4,10), you would find that for 3 squares to the right, you go up 9

but now we need to find how far up you go for ONE square,

so you would do 9/3 = 3

3 up per one square over!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

okay, now let's apply this to function A

for this next step, remember that this works for any two points on the line

you can see that when x is at 1, y is at 5, so that represents a point at (1,5)

there is also a point at (2,7)

now imagine in your head you are looking at line that goes from (1,5) to (2,7)

how far up does the line go? Because you are going from 5 to 7, it goes up 2. If you're working with bigger numbers you can simply subtract, like 7-5 = 2.

next we need to know how far over the line goes. The x values go from 1 to 2, so that means you move one square to the right. This makes sense because 2-1 = 1

so, per every 1 square over, you move up 2, and therefore the slope is 2

Answer:

-4e - 9

Step-by-step explanation:

This requires combining like terms, which means that you combine the same types of values. In this one there are two "types" of values: something that involves the variable e and just normal numbers. Let's say that the "e"s are oranges and the regular numbers are apples. Remember, you can't simply add oranges and apples together

let's start with apples (the regular numbers)

you have -19 (just pretend the minus sign is attached to the value following)

and +10

so -19+10 is -9

we have -9 apples

so now let's look at oranges, represented by e

you have 3e and -7e

if one e is one orange, then you could say that there are 3 oranges and -7 oranges

so if you subtract you get -4e, or -4 oranges

now let's add that back together with the apples, remembering that you can't actually combine them

so it would be -4e - 9

(-4 oranges and -9 apples)
