Answer:

Find "f(6)" __-8__

Find x when "f(x)=2" __x=1__

Step-by-step explanation:

For the first part, we will substitute 6 into the f(x) to get "-2(6)+4" When simplified further, you get "-12+4" which is "-8"

For the second part we will substitute the two as the answer of f(x) "-2x+4=2" Simplifying this further we get "-2x=-2" This means that x=1

Answer:

A(-2/3)

B(-1/6)

C(1/2)

D(4/3)

There are 6 tics in each section.

That means each tic is 1/6

A(-4/6) -> (-2/3)

B(-1/6)

C(3/6) -> (1/2)

D(8/6) -> (4/3)

Answer:

a) £600

b) £1400

Step-by-step explanation:

a)

original price = x

reduced price = £420

reduced price is 70% of original price

Since the discounted price, £420, is 70% of the original price, x, then

70% of x = 420

0.7x = 420

x = 420/0.7

x = 600

Answer: £600

b)

original price = x

discounted price = £840

discount percentage = 40%

The original price is x, and x is 100% of the original price since 100% is the whole amount. The discount is 40% of the original price. 100% - 40% = 60%. That means the discounted price is 60% of the original price.

60% of x = 840

0.6x = 840

x = 840/0.6

x = 1400

Answer: £1400

Answer:

mΔ1 = 42°

mΔ2 = 42°

Step-by-step explanation:

Δ1 + 138° = 180°

Δ1 = 180° - 138°

Δ1 = 42°

Δ2 + 138° = 180°

Δ2 = 180° - 138°

Δ2 = 42°

The product (2y - 6)² of the  algebraic expression gives 4y² - 24y + 36

An algebraic expression is an expression that is made up of variables and constants, along with algebraic operations like addition, subtraction, square root, etc.

The product (2y - 6)² can be written as:

(2y - 6)² = (2y - 6)(2y - 6)        (clear the parenthesis)

             = 2y(2y - 6) -6(2y - 6)

            = 4y² - 12y - 12y + 36

            =  4y² - 24y + 36

Answer:

The correct answer is D

Step-by-step explanation:

The  graph of inequality y ≤ -2x is option D .

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

According to the question

y ≤ -2x  

The graph of inequality  

at x = -2

y≤ 4

at x = 3

y ≤ -2*3

y ≤ -6  

Hence, the  graph of inequality y ≤ -2x is option D .

Answer:

The length is x + 5y

The width is x - 2y

But see below.

Step-by-step explanation:

Remark

The point of this question is to factor the trinomial. It can be factored.

(x  5y)(x  2y )

has to be the beginning of the factoring process.

(x - 5y)(x + 2y) The signs are right. The factoring isn't. The middle term has to be plus.

(x + 5y)(x - 2y)

The length is x + 5y

The width is x - 2y

x must be larger than 2y, otherwise you will get a negative width. That  cannot be right.

The expression 3(r/t) "the quotient of three times a number, and 7 option (C) 3(r/t) is correct after applying the arithmetic operation.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

It is given that:

The expression is:

The quotient of three times a number and 7

Let the two numbers be r and t:

On division:

= r/t

= 3(r/t)

Thus, the expression 3(r/t) "the quotient of three times a number, and 7 option (C) 3(r/t) is correct after applying the arithmetic operation.

Answer:

y = 18/5(11)

Step-by-step explanation:

If y varies directly as x, this is expressed as;

y∝x

y = kx

k is the constant of proportional constant

if y = 18 and x = 5

18 = 5k

k = 18/5

to get the expression that can be used to find the value of y when x is 11

y = kx

y = 18/5(11)

This gives the required expression
