Suppose y varies directly as x, and y=14 when x=4. What is the value of y when x=9

Katena32 [7]

Given :-

y varies directly as x, and y=14 when x=4.

To Find :-

the value of y when x=9 .

Solution :-

According to Question ,

y = kx ( k is constant )

When y = 14 and x = 4 ,

14 = k(4)
k = 14/4
k = 7/2

When x = 9 ,

y = 7/2*9
y = 63/2
y = 31.5

Please help I really need help please

Answer:

Step-by-step explanation:

The side lengths must satisfy the Pythagorean Theorem to be a right triangle. The formula is $a^2 + b^2 = c^2$ where a is the smallest side, b is the medium side, and c is the largest side. Test each set of numbers.

$a = 6, b = 8, c= 10\\6^2 + 8^2 = 10^2\\36 + 64 = 100\\100 = 100$

This satisfies the theorem. Since this is a multiple choice question, only one solution is possible. A is the solution.

1. (10 points) Explain how to factor the following:

kap26 [50]

Answer:

A. 3m² + 4m + 1 = 0

3m² + 3m + m + 1 = 0

3m (m + 1) + 1 (m + 1) = 0

( 3m + 1 ) (m + 1) = 0

B. 16n - 25

16n = 25

n = 25/16

How many pounds and ounces are there in 26 oz?

a_sh-v [17]

1 pound = 16 ounces

_ pound = 26 ounces

Multiply 1 × 26 = 26

Divide 26 ÷ 16 = 1.625 or 2

So, 1.625 or 2 pounds will equal to 26 ounces.

Hope this helps :)

Explain how you can use absolute value to tell wether the sum of two integers is positive or negative

Rudiy27

Step-by-step explanation:

Using absolute value to tell wether the sum of two integers is positive or negative.

Suppose we have a positive integer,

x and a negative interger, -x and we want to find their sum, we take the absolute values of each of the integers, that is |x| and |-x|. Then we subtract these values: |x| - |-x|. If the larger integer is positive, the result of the difference is positive, but if the larger number is negative, the result of the difference is negative.

For any integer x, x + (-x) = 0
