Answer:
Answer: y=2x+13.
Step-by-step explanation:
Your input: find the equation of the line perpendicular to the line y=5/2−x/2 passing through the point (−4,5).
The equation of the line in the slope-intercept form is y=5/2−x/2.
The slope of the perpendicular line is negative inverse: m=2.
So, the equation of the perpendicular line is y=2x+a.
To find a, we use the fact that the line should pass through the given point: 5=(2)⋅(−4)+a.
Thus, a=13.
Therefore, the equation of the line is y=2x+13.
Answer: y=2x+13.
Answer:
Step-by-step explanation:
Sum of angles of a triangle = 180
x + (180 - 105) + (180 -140) = 180
x + 75 + 40 = 180
x = 180 -75 - 40
x = 65
It sucks that points have to be used in order to post questions.
Openstudy - the company that merged into Brainly - was much better.
Anyway, I think that the answer to this question is A. I'm not sure, though.
Answer:
here's the solution,
let the given ratios as constants, by multiplying with same variable x
the angles will be 3x , 7x and 2x
now, we know the sum of the given angles measures 180°, since the sum of measures of all interior angles of a triangle is 180°
=》3x + 7x + 2x = 180°
=》12x = 180°
=》x = 15°
so, the measures of each angle is :
3x = 15 × 3 = 45°
7x = 15 × 7 = 105°
2x = 15 × 2 = 30°
and now, we can observe that the largest angle is 105°
1/3x + 2 = 4/3x - 5
2 + 5 = 4/3x - 1/3x
7 = x
y = 1/3(7) + 2
y = 7/3 + 2
y = 7/3 + 6/3
y = 13/3
solution is : (7,13/3) <=
