Answer:

Step-by-step explanation:

<u>Step 1: Determine if linear</u>

No, since the x term is squared, that produces the bend that makes a parabola. If the x term is not squared is just by itself, that is a linear equation.

Answer: NO

5 2/3 gave to her 4 friends how much did each one receive

Olin [163]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

If it is 5 + 2/3

_________________________________

Step (1)

First we have to find all she has :

$5 \frac{2}{3} = 5 + \frac{2}{3} = \frac{5 \times 3}{3} + \frac{2}{3} = \\ \frac{15}{3} + \frac{2}{3} = \frac{17}{3}$

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

$\frac{17}{3} \div 4 = \frac{17}{3} \times \frac{1}{4} = \frac{17}{12} \\$

So each of her friends receive 17/12 .

_________________________________

If it is 5 × 2/3

_________________________________

Step (1)

Firs we have to find all she has :

$5 \times \frac{2}{3} = \frac{10}{3} \\$

_________________________________

Step (2)

To find how much did each of them receive , we must divided all by the number of her friends which is 4.

So we have :

$\frac{10}{3} \div 4 = \frac{10}{3} \times \frac{1}{4} = \frac{10}{12} \\$

So each of her friends receive 10/12 .

_________________________________

And we're done.

Thanks for watching buddy good luck.

What is the equation of a line perpendicular to y= 3/4x +12 that passes through (12, 3)

ycow [4]

Answer:

y=-4/3x-9

−

Step-by-step explanation:

First we need to get the slope of the perpendicular line

The slope of a perpendicular line is equal to the negative inverse of the slope of the given line

−

⇒

−

⇒

−

⇒

−

Now that we have the slope, we need to find the y-intercept.

To find the y-intercept, we need to plug-in values of

and

that the line passes through

⇒

−

⇒

−

(

−

)

⇒

−

Therefore, the equation of the line is
