Answer:

  4

Step-by-step explanation:

To find the value of g(7), locate 7 on the x-axis. Follow the grid line upward until it meets the graph (blue line). At that point, follow the grid line to the left until it meets the y-axis. Read the value from the scale on the y-axis.

  g(7) = 4

You question is a little unclear but I'm going to assume you meant how much the guinea pig walked.

The hamster walked 20 feet, and the guinea pig walked 1/4 less. So you find 1/4 of 20, which is 5. Then, you subtract 20 and 5: 20-5 = 15. So the guinea pig walked 15 feet.

56%

Answer:v= 17/48

Step-by-step explanation:

-12v=1/4-9/2 move constant to the right hand side and change its sign

-12v=-17/4 subtract the fractions

v=17/48 divide both sides by -12

**my previous answer was wrong

Answer:

True

Step by Step explanation:

the absolute value bars are limiting the y value not x so any number between negative infinity and positive infinity can be in the domain

Answer:

The first table

Step-by-step explanation:

A linear function is represented when x and y are increased at a constant rate. In the first table, you can see that as x increases by 1, y increases by 1/2, thus the first table is a linar function.

Filling in your tax return online can make payments easier because a computer does what it's told to do ; with absolutely no mistakes, unless a bug occurs.

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

Multiply 12 and 2 by 3 to get the "easier to work with" fraction

[tex]\frac{12}{1}[/tex] = [tex]\frac{36}{3}[/tex]

Now, multiply two until you get 36

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36

It takes 18 times to get to 36.

That means the answer is 18.

Answer:

17

Step-by-step explanation:

if you subtract 4 from 89, which is the shipping cost. 89 - 4 = 85. Then divided 85 by 5 because that will show how much he paid for them in total, by how much a singular book is. Telling you how many books he bought. 85/5 = 17.

Answer:

A.) 5b+4=89

B.) 17 books

Step-by-step explanation:

To find A.), we must create a linear equation. Let b be the number of books Sam ordered. We write 5b because each book is 5 dollars. Then we add 4 dollars to the equation to represent the shipping fee. Then we write "equals to 89",  because it says that is the total cost. So we get the equation 5b+$4=$89

To find B.), we must solve the equation. Isolate the variable, by subtracting 4 from both sides. We then get 5b=$85. Now we divide by 5 to get only the variable and to get rid of the coefficient. We get b=17. So Sam bought 17 books.

Answer: ∠BEA ≅ ∠BEC

Step-by-step explanation:

Answer:

123°

Step-by-step explanation:

A supplementary is an angle where two angles add up to be 180°.We can subtract to find its supplement.

180 - 57 = 123°

Best of Luck!

Answer:

123°

Step-by-step explanation:

The supplementary angle is the other angle that makes both angles a linear pair.

So you would do 180° - 57° to solve your answer, which equals 123°

Hope this helps!

Answer:

81

Step-by-step explanation:

3(21 + 6)

(3 x 21) + (3 x 6)

63 + 18

81

Answer:

3*21+3*6     =   81

Step-by-step explanation:

3(21+6) is basically 3 times 21 plus 3 times 6. You are distributing the 3 to the 21, and then also to the 6. Once you distribute the 3, you get 3*21+3*6.  First, multiply 3 by 21 to get 63. Then, multiply 3 by 6 to get 18. Follow the equation and add them together to get your answer of 81.

You could also do it a different way and instead of doing 3*21+3*6, you could do the original equation, and do 3(21+6).  21+6=27    You then have 3(27).      3 times 27 is 81. You get the same answer, you could just do it a different way.

Answer:

You're right must be a different problem

Answer:

Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft

Step-by-step explanation:

Amount of  sausage links made on Friday morning = 8 ft

Amount of  sausage links used on Friday night = 4 ft

Amount of  sausage links remaining = 8 - 4 = 4ft           (i)

Amount of  sausage links made on Saturday morning = 8 ft         (ii)

So,

Total amount of  sausage links = 8 + 4 = 12 ft   (from (i) and (ii) )

Amount of  sausage links used on Saturday night = 12 ft

Amount of sausage links remaining = 12 - 12 = 0 ft

Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft

Answer:

L

Step-by-step explanation:

the square root is 7.2111111. thats the closest

Answer:

C. l

Step-by-step explanation:

The square root of 52 is about 7.211.

Since there is a negative sign in front of the square root, then it means that the answer is about -7.211.

On the number line you have a little bit over -7.3, a little less than -7.3 and a little more than -7.2. The closest answer would be the point that is a little more than -7.2.

Answer:

5 feet

Step-by-step explanation:

When you place the 13 foot ladder, the ladder, floor, and wall forms a right triangle and the ladder will become the hypotenuse.

We use the Pythagorean Theorem. Let x be the distance from the building.

x^2 +12^2 = 13^2

x^2 + 144 = 169

x^2 = 169 - 144

x^2 = 25

Take the square root of 25 and you get 5

x = 5

To find the point slope of a line you must first know the slope of the two points. You would substitute the points into the slope formula y2-y1/x2-x1.

Then you would put the slope into the point slope formula:

y-y1=m(x-x1)

"m" is the slope of the formula.

Answer:

It would be $7.50.

Step-by-step explanation: 2 pounds of bananas is $3, so we know that 4 pounds of bananas would be $6. Now, 1 pound of bananas would be $1.50! Because 1 pound is half of 2 pounds. Knowing this, one pound of bananas would be $1.50, beucuase its half.
