Graph the line y = 2x - 5

Papessa [141]

Answer:

The Explanation is below with attachment.

Step-by-step explanation:

For the line y = 2x - 5

For Drawing a line on a graph we require minimum two points, but we will plot three points.

Here you can take any random value for X so that the corresponding Y value you will get.

So, put x = 0, in the equation we will get

$y = 2(0) - 5\\\therefore y = -5\\\therefore Let\ A(0,-5)$

Similarly,

Put x = 1 we will get,

$y= 2(1)-5\\\therefore y =-3\\\therefore Let\ B(1,-3)$

Again,

Put x = -1 we will get,

$y= 2(-1)-5\\\therefore y =-7\\\therefore Let\ C(-1,-7)$

Now we have three points say point A (0,-5)), point B (1.-3) and point C (-1,-7)

Find the

Mazyrski [523]

Answer:

54 cm

Step-by-step explanation:

The area (A) of an equilateral triangle is

A = $\frac{s^2\sqrt{3} }{4}$ ( s is the side length ) then

$\frac{s^2\sqrt{3} }{4}$ = 81 $\sqrt{3}$ ( multiply both sides by 4 to clear the fraction )

s² $\sqrt{3}$ = 324 $\sqrt{3}$ ( divide both sides by $\sqrt{3}$ )

s² = 324 ( take the square root of both sides )

s = $\sqrt{324}$ = 18

Thus

perimeter = 3 × 18 = 54 cm

Colin invests £2200 into his bank account. He receives 2.5% per year simple interest. How much will Colin have after 3 years? Gi

Helga [31]

Answer:

Colin will have $2365 after 3 years.

Step-by-step explanation:

Using PRT/100, we can find the interest and then sum it up with the principle amount.

=> 2200 x 2.5 x 3/100 = Interest
=> 22 x 2.5 x 3 = Interest
=> 55 x 3 = Interest
=> 165 = Interest
=> 2200 + 165 = Total amount
=> $2365

Hence, Colin will have $2365 after 3 years.

Hoped this helped.
