Answer:

+(1/3), assuming a corerection is made in the equation. (see below)

Step-by-step explanation:

The formaula provided is not a function. It simply states that f(x) = -(2/9) + (1/3). My response will assume that an "x" was intended after the -(2/9):

f(x) = -(2/9)x+1/3

A straight line have the form y = mx + b. IIt is comprised of the slope of the line, m (-2/9) and the y-intercept b (1/3). The y-intercept is the value of y when x is 0. That would be (1/3). Thus, (1/3) is the y-intercept.

Q1. Find y, if √12 - √147 + y√3 = 0

o-na [289]

Answer:

Q1. y = 5 Q2. (√2 - √3)/2

Step-by-step explanation:

√12 - √147 + y√3 = 0

Taking -√147 and √12 to the right hand side, we have

y√3 = √147 - √12

y√3 = √(3 × 49) - √(3 × 4)

y√3 = √3 × √49 - √3 × √4

y√3 = √3 × 7 - √3 × 2

y√3 = 7√3 - 2√3

y√3 = 5√3

Dividing both sides by √3, we have

y√3/√3 = 5√3/√3

y = 5

Sin45° - Cos30°

Since Sin45° = √2/2 and Cos 30° = √3/2

Substituting these values into the equation, we have

Sin45° - Cos30° = √2/2 - √3/2

Taking L.C.M of both factors, we have

Sin45° - Cos30° = (√2 - √3)/2

What is BC ? Enter your answer in the box. units?

White raven [17]

Answer:

The length of the BC is 25 units .

Step-by-step explanation:

As shown in the diagram

In ΔABC

∠B = ∠C (As given)

(If the angles are equal than their opposite sides are also equal .)

Thus

AB = BC

As given

AB = 4x + 4

AC = 6x - 14

Thus

4x + 4 = 6x - 14

6x - 4x = 14 + 4

2x = 18

$x = \frac{18}{2}$

x = 9

Put in the

BC = 2x + 7

= 2 × 9 + 7

= 18 + 7

= 25 units

Therefore the length of the BC is 25 units .
