Answer:
r = 7
Step-by-step explanation:
To solve this, we can plug in a pair of x and y values and solve for r.
y = rx | Plug in a pair
42 = r*6 | Now divide both sides by 6
7 = r.
We can test this by plugging in r with a pair.
y = (7)x
77 = 7*11, 77 = 77, This equation is correct.
Answer:
No, this is because the word obtuse is in the name obtuse triangle as well as it being a whole different angle than an acute angle. Obtuse angles are are greater than 90 degress but less than 180 while the acute angle is less than 90.
Step-by-step explanation:
I'm not sure if this question was correctly transcribed but is it suppose to read find if x=15, find y = 6x+30 ?
If so then y = 120
The way it is written now, If x = 15 then 6x cannot equal 30 which is why I asked. Sorry if I'm not understanding the question.

Answer:
y = 1/5x -2
Step-by-step explanation:
When a point and slope are given, sometimes it is easiest to start with the point-slope form of the equation. Then it can be rearranged to the desired form.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y -0 = 1/5(x -10) . . . . . line with slope 1/5 through point (10, 0)
y = 1/5x -2 . . . . . . . eliminate parentheses to get slope-intercept form
_____
Note that the slope in the attached picture is 1/5, but your problem text says it is 5. Very different equations will result from these different slopes.
