Answer:

Red

Step-by-step explanation:

Let x = number of laps and Let y = time taken to complete laps

She is able to run one lap in 7 minutes

Given this information we want to create an equation

the equation would be

7x = y

Now that we have created an equation we want to find how many laps she can run in 56 minutes.

The time is represented by 7 so we plug in 56 into y

so now we have

7x = 56

Finally we solve for x

*divide each side by 7*

56/7 = 8

7x / 7 = x

we're left with x = 8 meaning that she can run 8 laps in 56 minutes

In conclusion the answer is the Red one

What is the midpoint of AB?
Citrus2011 [14]

Answer:

(-4, -\frac{1}{2})

Step-by-step explanation:

Hi there!

We are given the line segment, with the end points AB

The coordinates of A are (-5, -4), and the coordinates of B are (-3, 3).

We want to find the midpoint of the line segment AB

The midpoint formula is given as (\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2}), where (x_1, y_1) and (x_2, y_2) are coordinates

We have two coordinates, which is what we need, but let's label their values to avoid any confusion:

x_1=-5\\y_1=-4\\x_2=-3\\y_2=3

Now substitute those values into the formula:

(\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})

(\frac{-5+ -3}{2}, \frac{-4+ 3}{2})

Now simplify the numerator and denominator

(\frac{-8}{2}, \frac{-1}{2})

Simplify again:

The midpoint is (-4, -\frac{1}{2})

Hope this helps!

If f (a.b) = f(a) + f(b) and f (2) = 3, then f (32) equals how can we get 15 after this
attashe74 [19]
Hello,

f(4)=f(2*2)=f(2)+f(2)=3+3=6
f(8)=f(2*4)=f(2)+f(4)=3+6=9
f(16)=f(2*8)=f(2)+f(8)=3+9=12
f(32)=f(2*16)=f(2)+f(16)=3+12=15
