Which function is the inverse of f(x)=2x+3

2 answers:

6 0

The answer would be:

f(x) = -2x-3

Because the answer would be the same number but not positive, instead, negative.

Hope it helped,

Happy homework/ study/ exam!

Find x in terms of f(x):-

f(x) = 2x + 3
2x = f(x) - 3
x = (f(x) - 3) / 2

so the inverse = f-1(x) = (x - 3) / 2

Decide whether there is enough information to prove that △WXZ≅△YZX using the SAS Congruence Theorem.

Ratling [72]

Answer:

Step-by-step explanation:

ΔWXZ and ΔYZX

WZ ≅XY {Given}

ZX ≅ ZX {Reflexive property}

∠W ≅ ∠Y

But for SAS congruent the congruent angles should between congruent sides( WX & WZ should be congruent to ZY & XY respectively).

So it cannot be proved using SAS congruent

Lanya's house is located at (2 2/3, 7 1/3) on a map. The store where she works is located at (-1 1/3, 7 1/3). what is the distan

notka56 [123]

Answer:

Option A: 4 units is the correct answer.

Step-by-step explanation:

Given that:

Layana's house is located at ( $2\frac{2}{3}, 7\frac{1}{3}$ )

Store is located at ( $-1\frac{1}{3},7\frac{1}3}$ )

We can find distance between two points by using distance formula.

S = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

The points can also be written as;

House (8/3, 22/3)

Store (-4/3, 22/3)

Putting values in the formula.

S = $\sqrt{\frac{8}{3}-(-\frac{4}{3}))^2+(\frac{22}{3}-\frac{22}{3})^2$

S = $\sqrt(\frac{8}{3}+\frac{4}{3}+0$

S = $\sqrt{(\frac{8+4}{3})^2$

S = $\sqrt{(\frac{12}{4})^2$

S = $\sqrt{(4)^2$

S = 4 units

Hence,

Option A: 4 units is the correct answer.

What is the value of x?<br> A.2<br> B.3<br> C.6<br> D.7

Ira Lisetskai [31]

Answer:

Step-by-step explanation:

Given 2 secants from a point outside the circle.

Then the product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is

(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)

(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides

x² + 13x + 12 = x² + 9x + 20 ← subtract x² + 9x from both sides

4x + 12 = 20 ( subtract 12 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2 → A
