Answer:
The value of k is -5.
Step-by-step explanation:
To find the value of k, start by using the known information we have in the equation for slope. The equation is below.
m(slope) = (y2 - y1)/(x2 - x1)
In this equation, the first ordered pair would be (x1, y1) and the second would be (x2 , y2). So we put the values in for these variables and we get.
-1/5 = (-7 - k)/(6 + 4)
-1/5 = (-7 - k)/10
Now we can use cross multiplication to solve for k.
-1/5 = (-7 - k)/10
-1*10 = 5(-7 - k)
-10 = -35 - 5k
25 = -5k
-5 = k
Answer:
110
Step-by-step explanation:
A quadrilateral's angles always add up to 360 degrees. This is because a triangle has 180 degrees, and a quadrilateral can always be split into two triangles.
This said, we can set up the following expression:
40+128+82+x=360
168+82+x=360
250+x=360
x=110
The second graph is the slowest because the STEEPER the line, the faster the object is moving.

Answer:
The answer is 4w-5 its in its simplest form
We can find this answer by multiplying .14 by 87.6 to represent 14 cents for every mile.
87.6
<u> .14
</u>12.264
Since we are rounding to the nearest cent, that being the hundredths place, we know that it cost $12.26 to run the van that day.
