All the items on the sale rack were 75 percent off their original price.

Mathematics
1 answer:
tresset_1 [31]3 years ago
4 0

Answer:

112 $ is the original price

Step-by-step explanation:

x \times 0.75 = 84 \\ x = 84 \div 0.75 \\ x = 112

you have to think that the original price multiplied by 0.75 (also known as 75%) gave the result of what he saves i.e 84 $. So we put up an equation with the original price multiplied by 75% which equals the 84 $ he saved on buying that item on sale

Fill in the table with the next four terms of the sequence a1=4 and an=3an – 1, if n≥2.
Alexeev081 [22]

Answer:

12, 36, 108, 324

Step-by-step explanation:

using the recursive formula and a₁ = 4 , then

a₂ = 3a₁ = 3 × 4 = 12

a₃ = 3a₂ = 3 × 12 = 36

a₄ = 3a₃ = 3 × 36 = 108

a₅ = 3a₄ = 3 × 108 = 324

Help asap!<br><br> Thanks in advance!<br><br> There's two questions btw:)
lutik1710 [3]

Answer:

[1].

Option A and D are correct.

[2].

Option A is correct

Step-by-step explanation:

[1].

Quadratic function states that it is an equation of second degree i.,e it contains at least one term that is squared.

The standard form of the quadratic equation is; ax^2+bx+c = 0

A.

y(y+4)-y = 6

Using distributive property: a\cdot (b+c) = a\cdot b + a\cdot c

y^2+4y-y=6

Combine like terms;

y^2+3y = 6

or

y^2+3y -6=0 which represents a quadratic equation.

B.

3a-7 = 2(7a-3)

3a-7 = 14a-6

or

11a+1 = 0 which is not a quadratic equation.

C.

(3x+2)+(6x-1) = 0

Combine like terms;

9x +1 = 0 which is not a quadratic equation.

D.

4b(b) = 0

4b^2 = 0 which represents the quadratic equation.

[2].

Given the parent function: y=x^2

The reflection rule over x axis is given by;

(x, y) \rightarrow (x, -y)

then

the function become: y = -x^2

Vertical shift:

If c is a positive real number, the graph y=f(x)+c is the graph of y =f(x) shifted upward c units.

If c is a positive real number, the graph y=f(x)-c is the graph of y =f(x) shifted downward c units.

then;

The graph y=-x^2-3 is the graph of y=-x^2 shifted 3 units down.

Therefore, the translation of the graph of  y=x^2 to obtain y=-x^2-3 is, reflect over the  x-axis and shift down 3
