If ƒ(x ) = 3x + 1 and ƒ -1 = , then ƒ -1(7) =

Elden [556K]

F(x) = 3x + 1

let f(x) = y

y = 3x + 1

y - 1 = 3x

3x = y - 1

x = (y - 1)/3

From y = f(x), x = f⁻¹(y)

x = (y - 1)/3

f⁻¹(y) = (y - 1)/3

f⁻¹(7) = (7 - 1)/3 = 6/3 = 2

f⁻¹(7) = 2

The legs if an isosceles triangle are (3x^2+4x+2) inches and the base is (4x-5) inches. Find the perimeter of the triangle

alexdok [17]

Answer:

$P=(6x^2+12x-1)\ in$

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

The perimeter of triangle is equal to

$P=2(3x^2+4x+2)+(4x-5)$

Eliminate parenthesis

$P=6x^2+8x+4+4x-5$

Combine like terms

$P=(6x^2+12x-1)\ in$

The flower shop makes bouquets with ten flowers in each bouquet.

denis-greek [22]

I agree with with the florist because when you divide 207 by 10 you will get 20.7. This means that the florist could make 20 bouquets but seven flowers would be left out.
Hope this helps and please mark brainliest!

consider the function represented by the equation 16b = 4r - 12. write the equation in function notation, where b is the indepen

katovenus [111]

When you write a function in the form $y=f(x)$ , y is the dependent variable, and x is the independent variable.

So, if b is the independent variable, it means that we have to solve the expression for r.

To do so, we perform the following steps: start with

$16b = 4r - 12$

Add 12 to both sides

$16b+12 = 4r$

Divide both sides by 4:

$4b+3 = r$

So, we wrote the expression in the form $r = f(b) = 4b+3$ , which means that r is the dependent variable and b is the independent variable, as requested.
