Answer:

318 days or 10.6 months,

No, because the time between august and december is 8 months and it would take 10 to complete the tunnel

Step-by-step explanation:

start by determining the slope:

subtract the remaining distance from the total distance to determine distance so far, then divide by time.

m = (3200 - 1700)/5

m = 1500/5

m = 300

y = mx + b

Plug in to solve for x.

3200 = 300x + 0

3200 = 300x

divide y by m. This is x. (this is known as inverse operation if you didnt know already.)

3200 = 300(10.6_)

The third choice is right. The constant is 5.

In the equation 4x + 5...
4x is a term.
4 in 4x is a coefficient.
x is a variable, or a letter that represents an unknown value.
5 is a constant.

3 - what = 11<br><br> please help with this one
SOVA2 [1]
So we can set up a simple equation for this, where the word “what” is a variable, x. This equation is 3 - x=11. Then we subtract 3 from both sides, giving us -x=8. We can divide both sides by -1, giving us x=-8. The answer would be -8. Hope this helped.

For what value of k will the graph of 2x + ky = 6 be perpendicular to the graph of 6x – 4y = 12?
bekas [8.4K]
Perpendicular is when the slopes multiply to negative 1

remember
the slope of the line in form
ax+by=c is -a/b

find slopes

2x+ky=6
slope is -2/k

6x-4y=12
slope is -6/-4=3/2

so

-2/k times 3/2=-1
solve for k
-6/(2k)=-1
times both sides by 2k
-6=-2k
divide by -1
3=k

k has to be 3
