Step 1
<u>Find the slope of the line</u>
Let

the slope is equal to

substitute



Find the equation of the line
we know that
the equation of the line into slope-intercept form is

where
m is the slope
b is the y-intercept
in this problem we have

------> the y-intercept is the point A
substitute

Step 2
<u>Find the equation of the inequality</u>
we know that
the solution is the shaded area above the dotted line
so
above dotted line---------> represent the symbol (
)
the inequality is

therefore
<u>the answer is</u>

To find their mph you would have to divide by 2 to find out how much they got in 1 hour instead of 2. You would have to do 4 2/3 / 2. An easier way to do this is just doing 14/3 x 1/2 which is the same thing except making 4 2/3 a fraction and changing divided by 2 to multiply 1/2. The answer you would get is 14/6, which is 2 1/3 miles per hour. To do this quickly you could just look at the question and divide 4 by 2 to get 2 and then divide 2/3 by 2 to get 1/3 and then add them up.
Hope this helps!
Vertical angles equal each other so (13x-85) = 97
we can solve for x:
13x-85 = 97
add 85 to each side:
13x = 182
divide both sides by 13
x = 182 / 13
x = 14
z and 97 are supplementary angles and need to equal 180 degrees
z = 180 - 97 = 83
The answer is 6.05. Is it correct?
