Unit rates can be helpful with creating a ratio table and plotting the equivalent ratios on a coordinate plane. Explain why. PLEASE ANSWER ASAP AND PLEASE GIVE ME THE ANSWER!!!

### Answers

**Answer:**

Unit rate is often a useful means for comparing ratios and their associated rates when measured in different units. The unit rate allows us to compare varying sizes of quantities by examining the number of units of one quantity per one unit of the second quantity. This value of the ratio is the unit rate.

What is the solution to this system of equations? 4x + 5y = 7

3x – 2y =-12

The solution is

(-2, 3)

(3.-1)

(18. -9)

(13,-9)

### Answers

**Answer:**

(-2, 3)

**Step-by-step explanation:**

4x + 5y = 7

3x - 2y = -12

Let's solve this by elimination. We want to eliminate one variable at a time. This means we need to multiply the equations to create a common multiple to cancel out a variable.

Let's work with y.

5y and -2y: For these values to cancel out, we need to multiply each term to create a common multiple.

2(4x + 5y = 7)

5(3x - 2y = -12)

Multiply.

8x + 10y = 14

15x - 10y = -60

Eliminate.

23x = -46

Divide both sides by 23.

x = -2

Now that we know x, let's plug it back into one of equations to find y.

4x + 5y = 7

4(-2) + 5y = 7

Multiply.

-8 + 5y = 7

Add.

5y = 15

Divide.

y = 3

Now we know x and y; let's plug both back into the equation we have not checked yet.

3x - 2y = -12

3(-2) - 2(3) = -12

Multiply.

-6 - 6 = -12

Subtract.

-12 = -12

Your solution is correct.

(-2, 3)

Hope this helps!

There is an integer a such that a − 1 a is not an integer. For every integer a, a − 1 a is not an integer. There is an integer a such that a − 1 a is an integer. (b) Is the given statement true or false? If the statement is true, enter TRUE; if the statement is false, enter a value of a that could be used as part of a counterexample that justifies its falseness.

### Answers

**Answer:**

a) There is an integer a such that [tex]\frac{a-1}{a}[/tex] is an integer

b) False

**Step-by-step explanation:**

Statement : ∀a ∈ Z, (a − 1) a is not an integer

A) The correct negation will be :

**There is an integer a such that **[tex]\frac{a-1}{a}[/tex]** is an integer**

B) The Given statement is FALSE because

when we assume the value of a = 1

( a - 1 ) / a = (1 - 1 ) / 1 = 0 ; which is an integer

What is the quotient when (x+ 2) is divided into the polynomial 2x2 - 2x - 12?

O A. 2x-5 with no remainder

O B. X+ 3 with a remainder of -2

O C. 2x-3 with a remainder of 5

O D. 2x-6 with no remainder

### Answers

**Answer:**

2x² - 2x - 12 ÷ (x+2)

= 2x - 6

**D.**** ****2****x****-****6**** ****with ****no ****remainder**

The **quotient **when (x + 2) is **divided **into the polynomial 2x² - 2x - 12 is, (2x - 6) with no remainder.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that;

To find the **quotient **when (x + 2) is divided into the polynomial

2x² - 2x - 12.

Now,

The **polynomial **is,

⇒ 2x² - 2x - 12

⇒ 2 (x² - x - 6)

⇒ 2 (x² - 3x + 2x - 6)

⇒ 2 [ x (x - 3) + 2(x - 3) ]

⇒ 2 [ (x + 2) (x - 3) ]

Hence, We can **divide **polynomial by (x + 2) as;

⇒ 2 [ (x + 2) (x - 3) ] ÷ (x + 2)

⇒ 2 (x - 3)

⇒ 2x - 6

Therefore, the **quotient **when (x + 2) is **divided **into the polynomial

2x² - 2x - 12 is, (2x - 6) with no remainder.

### Answers

**Answer:**

180 cm^2

**Step-by-step explanation:**

**Remark**

If you put the slices that have been removed back into the figure, and figure out the resulting rectangle and subtract the slices, you get an answer that is easily calculated.

**Note**

The square on the upper right is 6 cm high. That makes the width of the rectangle 9 + 6 = 15. The length is already known as 15. So this square is 15 by 15 = 225

The lower right triangle is a little harder to handle. The total width is 15. The height of the triangle is 6 + 6. The first 6 comes from the square that was removed. The total with is 15. So the height of the lower right triangle is 15 - 12 = 3

Answer

The answer to the square on the upper left that was removed = 6*6 = 36

The answer to the triangle on the lower right is 1/2 * 6 * 3 = 9

The total of the removed figues is 36 + 9 = 45

The area of the figure with both figures removed is 225 - 45 = 180 cm^2

Addison sells plants. She sold 7 times as many as tomato plants as pepper plants, for a total of 64 plants sold. How many pepper plants did she sell? PLEASE SOMEONE GIVE ME THE ANSWER AHHHH

### Answers

She sold 8 pepper plants.

From this problem I made the equation

7p+p=64

I knew that it needed to be 7 times however many pepper plants she sold, so I substituted p until it equaled 64.

7*8+8=64

56+8=64

64=64

So she sold 8 pepper plants and 56 tomato plants for a total of 64 plants.

**Answer:**

8 pepper plants were sold.

**Step-by-step explanation:**

Assuming [tex]x=[/tex] the number of pepper plants sold, she sold [tex]7x[/tex] tomato plants and [tex]x[/tex] pepper plants, and since tomato plants sold + pepper plants sold = 64, we can turn this into the equation [tex]7x+x=64[/tex]. To solve this first we combine like terms to get [tex]8x=64[/tex]. Cancel the 8 by dividing both sides by 8 and we get [tex]x=8[/tex], which is the number of pepper plants sold. (We could also multiply x by 7 to get the number of tomato plants sold, which is 56.) Hope this helps!
