For all values of x f(x) = 3x + 2 Find f-¹(-12)

Mathematics
1 answer:
Novosadov [1.4K]2 years ago
8 0

Answer:

-4.67

Step-by-step explanation:

first find f^-1(x)

let f(x)=y

y=3x+2

3x=y-2

x=y-2/3

Therefore f^-1(x)=x-2/3

Now f^-1(-12)=-12-2/3

=-14/3

=-4.67

What is the slope of the line perpendicular to y=-3x+4?
inessss [21]

The perpendicular line would have a slope of 1/3.

Perpendicular lines have opposite and reciprocal slopes.

To do the opposite, take the original slope (-3) and change the sign (3).

To do the reciprocal, take the slope we changed (3) and flip it as a fraction (1/3).

This gives us a new slope of 1/3.

The coordinates of each rectangle ABCD are A (0,2) B (2,4) C (3,3) D (1,1). Find the distance of each side of the rectangle then
EastWind [94]

AB = CD = √8 ≈ 2.8 units

BC = AD = √2 ≈ 1.4 units

Area of the rectangle ABCD = 3.92 units²

Perimeter of the rectangle ABCD = 8.4 units

<h3>How to Find the Area and Perimeter of a Rectangle?</h3>

Given the coordinates of vertices of rectangle ABCD as:

  • A(0,2)
  • B(2,4)
  • C(3,3)
  • D(1,1)

To find the area and perimeter, use the distance formula to find the distance between A and B, and B and C.

Using the distance formula, we have the following:

AB = √[(2−0)² + (4−2)²]

AB = √[(2)² + (2)²]

AB = √8 ≈ 2.8 units

CD = √8 ≈ 2.8 units

BC = √[(2−3)² + (4−3)²]

BC = √[(−1)² + (1)²]

BC = √2 ≈ 1.4 units

AD = √2 ≈ 1.4 units

Area of the rectangle ABCD = (AB)(BC) = (2.8)(1.4) = 3.92 units²

Perimeter of the rectangle ABCD = 2(AB + BC) = 2(2.8 + 1.4) = 8.4 units

the base of a triangle is 5/8. The height is 1/3 feet. how much greater is base of the triangle than the height?
maks197457 [2]
Namely, how many times does 1/3 go into 5/8?  well, is their quotient,

\bf \cfrac{\quad \frac{5}{8}\quad }{\frac{1}{3}}\implies \cfrac{5}{8}\cdot \cfrac{3}{1}\implies \cfrac{15}{8}\implies 1\frac{7}{8}
