Answer:

The y intercept would be (0, 1/3)

The number at the end is always the y value. In a y intercept x is always 0.

Step-by-step explanation:

Midpoint of Hypotenuse

= [(0 + n)/2, (n + 0)/2]

= (n/2, n/2) or (0.5n, 0.5n).

A number times 5 increased by 4 is equal to that same number. Find the number.

MrMuchimi

Let the number be n. Then 5n + 4 = n. simplifying, 4n = -4, and n = -1

Solve for c.<br> -c/2+43 = 50

noname [10]

$\huge\text{Hey there!}$

$\mathsf{-\dfrac{c}{2}+43=50}$

$\large\text{SUBTRACT 43 to BOTH SIDES}$

$\mathsf{-\dfrac{c}{2}+43-43=50-43}$

$\large\textsf{CANCEL out: 43 - 43 because that gives you 0}$

$\large\textsf{KEEP: 50 - 43 because it helps solve for the c-value}$

$\mathsf{50 - 43 = \bf 7}$

$\large\text{NEW EQUATION: }\mathsf{-\dfrac{c}{2}=7}$

$\large\textsf{MULTIPLY }\mathsf{\dfrac{2}{-1}}\large\textsf{ to BOTH SIDES}$

$\mathsf{\dfrac{2}{-1}\times-\dfrac{c}{2}= \dfrac{2}{-1}\times7}$

$\large\textsf{CANCEL out: your RIGHT SIDE of the equation because that gives}\\\large\textsf{you 1}$

$\large\textsf{KEEP: }\mathsf{\dfrac{2}{-1}\times7}\large\textsf{ because that helps solve for the c-value}$

$\uparrow\large\text{SIMPLIFY THE EQUATION ABOVE \& YOU HAVE YOUR}\\\large\text{C-VALUE}\uparrow$

$\boxed{\boxed{\large\text{ANSWER: \huge\bf c = -14}}}\huge\checkmark$

$\large\text{Good luck on your assignment and enjoy your day!}$

(10 pts) A relation R is defined on the set Z by "a R b if a - b is divisible by 5" for a, b e Z. Examine if R is an equivalence

9966 [12]

Answer:

Yes

Step-by-step explanation:

Given that a relation R is defined on the set Z by "a R b if a - b is divisible by 5

for a, b in the set of integers.

Reflexive:

We have

for any a, $a-a=0 = 5(0)$

i.e. (a,a) is related. Hence reflexive

ii) Symmetric:

If a-b is divisible by 5, then b-a is also divisible by 5. Hence symmetric

iii) Transitive

If $a-b = 5m and\\ b-c = 5l$

adding we get

$a-c=5(m+l)$

Hence R is transitive

It follows that R is an equivalence relation on Z
