3) An existing track is perpendicular to y=1/2x + 2 and passes through B(7,5)
stira [4]

Answer:

2. y=\frac{1}{2}x +3

Step-by-step explanation:

2. The line will be parallel to the current track which means they have the same slope. To write the equation, use the slope m=1/2 and the point (2,4) in point slope form:

y-y_1=m(x-x_1)\\y-4=\frac{1}{2}(x-2)

This is the equation of the line. You can convert it to slope intercept form:

y-4=\frac{1}{2}(x-2)\\y-4 = \frac{1}{2}x -1 \y=\frac{1}{2}x +3

Pepsi [2]

Answer:

9 cm

Step-by-step explanation:

The formula to find the area of a square is Base times height (B x H)

Since a square has equal sides, it means each side is 3 centimeters.

So, all you have to do is 3 times 3.

3 x 3=9

<u>Final answer</u>

9 cm

What is the value of n so that the expression x^2+12X+n is a perfect square trinomial?
Anton [14]
N is equal = 36

Or

n = 6^2

Because,

x^2 + 12x + 36 = x^2 + 2.6x + 6^2

= ( x + 6)^2
