Answer:

Step-by-step explanation:
Here, we have to convert the equation to slope-intercept form so we can find the perpendicular slope:




Since our slope is
, then that means the slope perpendicular to it is
.
Now we find our new y-intercept so that the line will pass through the point (-7,7):





Therefore, the equation of the new line is 
each box weighed 10 more pounds
and he lifted 12 boxes
so if you multiply 12 x the weight and then 12 times 10 more pounds each you would have 12c +12*10
which uses the equation 12(c+10)
Answer:
7
Step-by-step explanation:
Since x and y are directly proportional , so x = ky
6 = 42k
k = 6/42 = 1/7
12= (1/7)y
y = 84
The answer to this question is 110.3 ft. Hope this helps.
