Can someone please answer this and show working out? thankyou.

Step-by-step explanation:

Using PEDMAS solve the expression

First solve the terms in the bracket first

When two negative signs meet it becomes positive.

We have

First convert the decimal to an improper fraction

That's

So we have

To solve change the division sign to multiplication sign and reverse the second fraction

That's

Multiply the fractions

Reduce the fraction by 6

We have the final answer as

Hope this helps you

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
