Look at the photo i send, and you will understand, i Hope that answer i get is correct which can help you
Angle A should be equal to 47
Answer:
the equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5)
= -5 = -2x + 15
Step-by-step explanation:
Write an equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5).
Using the slope intercept equation,
y = mx +c
m = slope = 1/2
For two lines to be perpendicular, the product of their slopes is -1
Let the slope of the other line be m2
m1×m2 =-1
1/2×m2 = -1
m2 = -1/(1/2) = -2
Slope of line = -2
For points (10, -5), x = 10, y =-5
-5 = -2× 10 +c
-5 = -20+ c
c = -5+20= 15
the equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5)
-5 = -2x + 15
Answer:
no idea what to find would you please like to explain about this question
Answer:
x = -2
y = - 5
Step-by-step explanation:
-5y - 10x = 45
-3y + 10x = -5
------------------------Add
-8y = 40
y = -5
-3(-5) + 10x = -5
15 + 10x = -5
10x = -20
x = -2
Answer
x = -2 and y = - 5
