Sum : $(5 x+1)$

Term : 1, $5x$ and $3y$

Product : $9(5x+1),5x$ and $3y$

Factor : 5 and x, 3 and y, 9 and 5x+1

Quotient : $\frac{9(5x+1)}{3y}$

Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.

Explanation:

The expression is $\frac{9(5x+1)}{3y}$

Sum: Sum is the result of addition of terms.

Thus, from the expression,

Sum = $(5 x+1)$

Term : A term is a single number or a variable or a number multiplied with a variable.

Thus, from the expression,

Term = 1, $5x$ and $3y$

Product : Product is the result of multiplication of numbers.

Thus, from the expression,

Product = $9(5x+1),5x$ and $3y$

Factor : The numbers that are multiplied is called a factor.

Thus, from the expression,

Factor = 5 and x, 3 and y, 9 and 5x+1

Quotient : Quotient is the result of dividing two numbers or variables.

Thus, the given whole expression is a quotient.

Hence, Quotient = $\frac{9(5x+1)}{3y}$

Coefficient : Coefficient of a variable is a number multiplied with a variable.

Thus, from the expression,

Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.

If (x + k) is a factor of f(x), which of the following must be true?

KIM [24]

Answer:

Step-by-step explanation:

(x + k) is a factor of f(x)

x+k=0 => <u>x= -k;</u> <em>-k is a root of f(x)</em>

=> f(-k)=0

A boat crew rowed 10.5 miles downstream, with the current, in 1.5 hours. the return trip upstream , against the current , covere

alukav5142 [94]

Answer:

The speed of the boat is 5 miles per hours

The speed of the current is 2 miles per hours .

Step-by-step explanation:

Given as :

The distance cover by boat downstream = D = 10.5 miles

The time taken by boat to cover D distance = T = 1.5 hours

The distance cover by boat Upstream = d = 10.5 miles

The time taken by boat to cover d distance = t = 3.5 hours

Let The speed of boat = x mph

Let The speed of current = mph

Now, According to question

∵ Speed = $\dfrac{Distance}{Time}$

<u>For Downstream</u>

x + y = $\dfrac{D}{T}$

Or, x + y = $\dfrac{10.5}{1.5}$

Or, x + y = 7 .......A

<u>For Upstream</u>

x - y = $\dfrac{d}{t}$

Or, x - y = $\dfrac{10.5}{3.5}$

Or, x - y = 3 .......B

Now, Solving eq A and eq B

So, (x + y) + (x - y) = 7 + 3

Or, (x + x) + (y - y) = 10

Or, 2 x + 0 = 10

∴ x = $\dfrac{10}{2}$

i.e x = 5 mph

So, The speed of the boat = x = 5 miles per hours

Put the value of x into eq A

∵ x + y = 7

Or, 5 + y = 7

∴ y = 7 - 5

i.e y = 2 mph

So, The speed of the current = y = 2 miles per hours

Hence, The speed of the boat is 5 miles per hours and The speed of the current is 2 miles per hours . Answer
