It will take three days !!

Answer:

2 Days

Step-by-step explanation:

If April is able to complete the project in half the amount of time that Bob is, this means that she works twice as fast as Bob. If they work together, then, April will complete twice as much of the work as Bob will. This system can be represented by a simple equation.

If the project takes April 3 days to complete the project, this means that she is able to complete 1/3 of the project every day she works.

If the project takes bob 6 days to complete the project, this means that he is able to complete 1/6 of the project every day he works.

Therefore, to complete one whole project, the equation would be:

1=1/6x+1/3x

↓

1=1/2x

↓

2=x

Working together, they will complete the project in 2 days.

Write a linear function f with f(−9)=10 and f(−1)=−2
pashok25 [27]

First we need to find the slope of the function

The slope of a function is equal to

\frac{f(x_2)-f(x_1)}{x_2-x_1}

So now we plug this into the equation and find the slope (M will represent the slope)

m=\frac{10--2}{-9--1}\\m=\frac{12}{-8}\\m=-\frac{3}{2}

So the slope is -3/2


Now we can use point-slope form.

Point slope form is represented by

Y-Y_1=m(X-X_1)

So when we plug in our values we get

Y--2=-3/2(X--1)\\Y+2 = -3/2(X+1)\\Y+2 = -3/2X-3/2\\Y=-3/2X-7/2

So the equation is

Y = -3/2X-7/2

The midpoint of the sides of triangle ABC are labeled D, E, and F. If the perimeter of triangle DEF is 24 find the perimeter of
AleksAgata [21]
Ok well the only thing that makes since to me is that the triangle is a Equilateral Triangle, so all the sides are going to be the same. And if the perimeter is 24, then you divide that by 3, and you get 8. And if DEF is the midpoints of triangle ABC, then DEF is an upside down triangle in the triangle ABC. So all the sides of ABC are double whatever DEFs are. And DEFs were 8, so 8 times 2 is 16. And to get the perimeter you add that together 3 times and you get 48. So i'm not sure exactly how you would do this, but i'm pretty sure this is the way. If not i'm sorry i couldn't help. :(

Find the x-intercepts of the following polynomial function''<br> f (x) = x^2 - 2x - 80
pychu [463]

Answer:

(-8 , 0)

(10 , 0)

Step-by-step explanation:

(-8)^2 - 2(-8) - 80 = 0

(10)^2 - 2(10) - 80 = 0

then (-8 , 0) and (10 , 0) are x-intercepts Of the polynomial f

the others are not because (for instance):

(8)^2-2(8)-80 =

:)-32
