If y varies directly as x and y=32 when x=4. find the constant of variation​
Llana [10]

Answer:

k = 8

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 32 when x = 4, then

32 = 4k ( divide both sides by 4 )

8 = k

Swap x and y, f^-1 is and solve for y to get f^-1 the inverse of f. f(f^-1)=f^-1(f)=x is the identity as a check
f(2)=3*2+1=7 (2,7)
f^-1(7)=2 (7,2)

How can addition properties help me add whole numbers
Bas_tet [7]

Answer:

There are four addition properties that help to add whole numbers :

For any  whole number a, b, and c ;

1. <u>Closure property of addition </u>-   a+b

For example:

2+3=5

4+3=7

We can conclude that if we add any two whole number , we get another whole number.

2. <u>Associative property of addition</u>- when any whole number or variable are added, then that can be grouped in different way without changing result

a+(b+c)=(a+b)+c

For example:  

2+(3+4)=(2+3)+4

3.<u> </u><u>Commutative property of addition</u>- when any  whole number or variable are added, then the order changed without changing the result.

a+b=b+a

For example: 2+3=3+2

4. <u>Identity property of addition</u>- when 0 is added to a whole number or variable , the result is the same variable or number.

a+0=0+a

For example: 3+0=0+3

0 is called an Identity for addition of whole numbers.

In the diagram below of triangle PQS, S is the midpoint of PR and T is the midpoint of QR. If ST = 5x - 22, and PQ = 3x + 19, wh
SIZIF [17.4K]

Answer:

PQ = 46

Step-by-step explanation:

The midsegment ST is half the length of the third side PQ , that is

ST = \frac{1}{2} PQ , so

5x - 22 = \frac{1}{2} (3x + 19) ← multiply both sides by 2 to clear the fraction

10x - 44 = 3x + 19 ( subtract 3x from both sides )

7x - 44 = 19 ( add 44 to both sides )

7x = 63 ( divide both sides by 7 )

x = 9

Then

PQ = 3x + 19 = 3(9) + 19 = 27 + 19 = 46
