Answer:

Not equivalent

Step-by-step explanation:

At first sight, without any computation, it is obvious that ⁸/₅ and ⁷/₉ are not equivalent by the fact that one of them is greater than one

(numerator > denominator), and the other is not (numerator < denominator).

I can not do question 8 since I can not see it.

Luke bought a jacket that was 30% off the cost. He paid sales tax of 6% after the discount had been applied. If the jacket had a
nasty-shy [4]

Answer: the actual amount that Luke paid including tax is $55.65

Step-by-step explanation:

The initial price of the jacket is $75.

Luke bought a jacket that was 30% off the cost. This means that the amount of discount on the Jacket is

30/100 × 75 = 0.3 × 75 = $22.5

The price of the jacket after the discount had been applied is

75 - 22.5 = $52.5

He paid sales tax of 6% after the discount had been applied. This means that the amount of sales tax that he paid on the jacket is

6/100 × 52.5 = 0.06 × 52.5 = 3.15

Therefore, the actual amount that Luke paid including tax is

52.5 + 3.15 = $55.65

Suppose that the functions r and s are defined for all real numbers x as follows.
mixas84 [53]
ANSWER

Given

r(x) = x - 1


and

s(x) = 3 {x}^{2}
ANSWER TO QUESTION 1

(r + s)(x) = r(x) + s(x)


(r + s)(x) = x - 1 + 3 {x}^{2}


(r + s)(x) =  3 {x}^{2}  + x - 1



ANSWER TO QUESTION 2



(r \times s)(x) = r(x) \times s(x)


(r \times s)(x) = (x - 1) \times 3 {x}^{2}


(r \times s)(x) = 3 {x}^{3}  - 3 {x}^{2}

ANSWER TO QUESTION 3

( r - s)(x) = r(x) - s(x)



( r - s)(x) = x - 1 - 3 {x}^{2}


( r - s)( - 3) =  (- 3) - 1 - 3 ({ - 3}^{2} )



( r - s)( - 3) =   - 4 - 3  \times 9



( r - s)( - 3) =   - 4 - 27 =  - 31

Which is a proportional relationship<br> y=x+1<br> y=3x+3<br> y=4x<br> y=8+x
yulyashka [42]

Answer:

4=4x

Step-by-step explanation:

the formula y=mx+b

corresponds to y=slope+y intercept

all proportional relationships start on the origin so the y-intercept is always 0

the fact that the equation y = 4x doesn't have an intercept shows its proportional this can go with any similar equation like y = 4.5x
