the equation of line that is perpendicular to 2x+y=3 & passes through points (2,-5) is:
Step-by-step explanation:
Given equation of line is:
Let m1 be the slope of given line and
m2 be the slope of line perpendicular to given line
The slope of first line will be (The coefficient of x)
m1 = -2
We know that the product of slopes of two perpendicular lines is -1
So,
slope-intercept form is:
Putting the value of slope we get
Putting the point in the equation
Putting the value of b
Hence,
the equation of line that is perpendicular to 2x+y=3 & passes through points (2,-5) is:

Answer:
c
Step-by-step explanation:
just put the first part in the calculator home screen and look at the answer
Answer:
a) 3x-5=16
b) 30cm
Step-by-step explanation:
a) 5(x-1)=2(x+8)
5x-5=2x+16
5x-2x-5=16
3x-5=16
b) solving the equation gives x=7
put x=7 into first line, 5(7-1)=30cm
to check we can place it into second one as well
2(7+8)=30cm
