I'll mark as Brainliest, Please answer ASAP, Ihave MCAS tomorrow. How could this be true?? Please Explain.​
Vaselesa [24]

Answer:

See below

Step-by-step explanation:

The number of loaves of bread remaining can only go as low as ZERO (you can't have negative loaves) ...and can only go as high as when h = 0

     so    0 = 42-3.5 h    

             3.5 h = 42

                h = 12       and   min is  h = 0   ( when there are 42 loaves to start)

So:

<u>0≤ h ≤ 12 </u>

Find YW. YW = _<br><br> I just need the answer for YW no explanation needed.
KATRIN_1 [288]

Answer:

YW=20\ units

Step-by-step explanation:

we know that

In a parallelogram the diagonals bisect each other

The figure XYZW is a parallelogram

so

VW=VY

VX=VZ

<em>Find the value of b</em>

VW=VY

substitute the given values

b+8=5b

solve for b

5b-b=8\\4b=8\\b=2

Find the length of YW

YW=YV+VW ----> by addition segment postulate

YW=5b+b+8

substitute the value of b

YW=6(2)+8=20\ units

Find an equation for line perpendicular to 2x+6y=18 and goes through the point (8,-1)
bazaltina [42]

Answer:

3x +y = -2

Step-by-step explanation:

First of all, it is helpful to put the given equation in standard form. We can do that by dividing it by 2 to eliminate the common factor from the numbers.

 x -3y = 5

Next, since you want the perpendicular line, you can swap the coefficients of x and y, and negate one of them. This can give you ...

 3x +y = (some constant)

The constant will be found using the given point.

 3x +y = 3(2) +(-8) = -2 . . . the perpendicular line

An equation is ...

 3x +y = -2
