You find the slope of line 5x-2y-8..then slope of line (l) × slope of line 5x-2y-8= -1.. You find the slope of (l).. Then (l) : y-yO=slope(x-xO)
Then you substitute..

The question is unclear, so I'm going to go with this being the original question:
5x-2y=8
From this starting point we can rearrange to find the gradient of the line.
y= (5/2)x +4

Therefore the line l, has gradient -2/5, from here we can see that the line must have equation y = (-2/5)x

Paul [167]

Answer:

2 1/3 cups

Step-by-step explanation:

The total number of cups of mixed nuts purchased is ...

(8 bags)·(3 1/2 cups/bag) = 8·3.5 cups = 28 cups

When those are shared 12 ways, each share is ...

(28 cups)/(12 shares) = (28/12) cups/share = 2 1/3 cups/share

Each share is 2 1/3 cups.

what is the length, in units, of the hypotenuse of a right triangle if each of the two legs is 3 units? square root of 18 units
AfilCa [17]

Answer:

Option 1 is correct that is square root of 18.

Step-by-step explanation:

We will use pythagoras theroem to find the length of hypotenuse

c^2=a^2+b^2

Here, c is hypotenuse,a is one leg and b is the other leg.

Here, a=b=3

On substituting the values in the formula we get:

c^2=3^2+3^2=18

c=\sqrt{18}

Hence, Option 1 is correct that is square root of 18.

A triangle has a height that is 4 /3 the length of its base. If the length of its base is 24 cm, what is its area?
ASHA 777 [7]
Triangle Area = ½ * height * base

base = 24 therefore
height = (4/3) * base = (4/3) * base = 32 cm

Triangle Area = ½ * 32 * 24
= 384 cubic centimeters

Archy [21]

Answer:

A. 12.5 miles per hour B. 0.36 hours

3.75/.30=12.5 , so divide 3.75 by the time 0.30 hours and you get your miles per hour

next, take 4.5 and divide by the new mph 12.5 from your previous answer.

4.5/12.5=0.36 hours
