Step-by-step explanation:
the red point is (4, -5).
so, y - (-5) = -1/7(x - 4)

Answer:
x=7
y=2
Step-by-step explanation:
10 + 2x = -2y ➡y = -5-x
replace y with -5-x in the first equation
-5-x-x = 9➡ -2x-5 = 9 ➡-2x = 9+5 ➡ x = -7
now use this information to find value of y
y - (-7)=9 ➡y = 2
We know that
An acute triangle is a triangle with all three angles acute (less than 90 degree ).
An obtuse triangle is one with one obtuse angle (greater than 90 degree) and two acute angles.
A right triangle is one with one right angle (angle equal to 90 degree ) and two acute angles.
therefore
The answer is
Is not possible
The first is going to be, D. & the second question is, C.
