Step-by-step explanation:

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

Answer:

Step-by-step explanation:

7x - 8(2x - 3) + 2 = 8

Expand bracket and Minus 2 on both sides

7x - 16x + 24 = 6

Minus 24 on both sides, and simplify the "x's"

-9x = -18

Divide by -9 on both sides

x = 2

Answer:

x = -2

Step-by-step explanation:

3{-x + 2x + 1} = x - 1

-3x + 6x + 3 = x - 1

3x + 3 = x - 1

2x = -4

x = -2

Answer:

Yellow:  [tex]\frac{8}{15}[/tex]

Step-by-step explanation:

tangent = opposite [tex]\div[/tex] adjacent

Opposite A = 16

Adjacent A = 30 (Not 34, since that is the hypotenuse or the longest line in the triangle)

Thus, tan A = [tex]\frac{16}{30} =\frac{8}{15}[/tex]

Answer:

8/15

Step-by-step explanation:

Since this is  a right triangle

tan theta = opp/ adj

tan A = 16/ 30

tan A = 8/15

Answer:

11 and 19

Step-by-step explanation:

solution

let,the lenght be (x+8) and width be x.

Now,

The perimeter of rectangle=2(l*w)

or,60=2(x+8*x)

or,60=4x+16

or,60-16=4x

or,44=4x

or,44÷4=x

x=11

breath=11

length=(x+8)

=11+8

=19

Answer:

-84

Step-by-step explanation:

Answer: Graph (0,10) and (3,9).

Step-by-step explanation: The equation is written in slope-intercept form (y=mx+b). b represents the y-intercept.

So you would graph (0,10) on the graph.

To find the other points, you can use the triangle method for finding slope. -1/3x is the slope. -1 means you go down by one space on the y line. 3 means you go right by 3 spaces on the x line. This leads you to the point (3,9). You can use this method to find the other points on the graph.

Answer:

[tex]\lim_{x \to 2} (x+1)(3x^2-9) = 9[/tex]

Step-by-step explanation:

Step 1: Write out limit

[tex]\lim_{x \to 2} (x+1)(3x^2-9)[/tex]

Step 2: Evaluate

(2 + 1)(3(2)² - 9)

3(3(4) - 9)

3(12 - 9)

3(3)

Answer:

m = - 2n + 5

Step-by-step explanation:

Given the equation:

m+1=-2n+6

Rearrange the equation so that n is the independent variable

The independent variable is the predictor variable, Hence causes a change in the value of predicted variable obtained.

m+1=-2n+6

m = - 2n + 6 - 1

m = - 2n + 5

m = - 2n + 5

The general form of a regression equation:

y = ax + b

Where y = dependent variable

x = independent variable ; a = Coefficient of slope ; b = intercept

Hence, the equation : m = - 2n + 5

Answer:

9y

Step-by-step explanation: Product is also the same thing of multiplication so 9 x y equals to 9y.

~~~~Inuola1234

The expression for the product of y and 9 is 9y.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The product of y and 9.

This can be written as,

= 9y

Thus,

The expression is 9y.

Factors  Multiples

1, 2, 3, 6 6 12

Step-by-step explanation:

Given :

Price of property , P = $145000 .

Money paid off in two ways a short term note at 11% interest and a long term note at 8% interest.

Total interest , I = $13850 .

To Find :

The amount of each note .

Solution :

Let , x money is paid off in 11 % interest rate and ( 145000-x) in 8% interest rate.

Therefore , their sum of interest in mathematics is given by :

[tex]\dfrac{11x}{100}+\dfrac{8(145000-x)}{100}=13850\\\\11x+1160000-8x=1385000\\\\3x=225000\\\\x=\$75000[/tex]

Therefore , the amount of note is $75000 and $70000 for 11% and 8% interest rate respectively .

Hence , this is the required solution .

Answer:

No, Sam is not correct. The graph of a proportional relationship has the form y = kx, where k is the constant of proportionality. Sam added the constant of proportionality instead of using it as the coefficient of x. The correct equation is y = 6x. Sam’s graph would be a straight line, but it would not pass through the origin.

I think you meant to write [tex]\{x | x \in \mathbb{N} \text{ and } 15 \le x \le 50\}[/tex]

If so, then the answer is Choice A. {15, 16, 17, 18, ..., 50}

We simply list every natural number from 15 to 50, including both endpoints. The three dots mean "continue this pattern". This way we don't literally have to write out every single value (there are 50-15+1 = 36 values in this set).

Note: the set of natural numbers is {1,2,3,...} so a natural number is basically a whole number, but 0 is not included. Negative values aren't included either.
